However, in order to 10 | execute the `go build` compilation process, the buildpack requires the `go` 11 | dependency that can be provided by a buildpack like the [Go Distribution 12 | CNB](https://github.com/paketo-buildpacks/go-dist). 13 | 14 | ## Usage 15 | 16 | To package this buildpack for consumption: 17 | 18 | ``` 19 | $ ./scripts/package.sh 20 | ``` 21 | 22 | This builds the buildpack's Go source using `GOOS=linux` by default. You can 23 | supply another value as the first argument to `package.sh`. 24 | 25 | ## Go Build Configuration 26 | Please set the following environment 27 | variables at build time either directly (ex. `pack build my-app --env 28 | BP_ENVIRONMENT_VARIABLE=some-value`) or through a [`project.toml` 29 | file](https://github.com/buildpacks/spec/blob/main/extensions/project-descriptor.md) 30 | 31 | ### `BP_GO_BUILD_LDFLAGS` 32 | The `BP_GO_BUILD_LDFLAGS` variable allows you to set a value for the `-ldflags` build flag 33 | when compiling your program. 34 | 35 | ```shell 36 | BP_GO_BUILD_LDFLAGS= -X main.variable=some-value 37 | ``` 38 | 39 | ### `BP_GO_TARGETS` 40 | The `BP_GO_TARGETS` variable allows you to specify multiple programs to be 41 | compiled. The first target will be used as the start command for the image. 42 | 43 | ```shell 44 | BP_GO_TARGETS=./cmd/web-server:./cmd/debug-server 45 | ``` 46 | 47 | ### `BP_GO_BUILD_FLAGS` 48 | The `BP_GO_BUILD_FLAGS` variable allows you to override the default build flags 49 | when compiling your program. 50 | 51 | ```shell 52 | BP_GO_BUILD_FLAGS= -buildmode=default -tags=paketo -ldflags="-X main.variable=some-value" 53 | ``` 54 | 55 | ### `BP_GO_BUILD_IMPORT_PATH` 56 | The `BP_GO_BUILD_IMPORT_PATH` allows you to specify an import path for your 57 | application. This is necessary if you are building a $GOPATH application that 58 | imports its own sub-packages. 59 | 60 | ```shell 61 | BP_GO_BUILD_IMPORT_PATH= example.com/some-app 62 | ``` 63 | 64 | ### `BP_GO_WORK_USE` 65 | The `BP_GO_WORK_USE` variable allows you to initialise a workspace file and add 66 | modules to it. This is helpful for building submodules which use relative 67 | replace directives and `go.work` is not checked in. Usually, this is set 68 | together with `BP_GO_TARGETS`. 69 | 70 | ```shell 71 | BP_GO_WORK_USE=./cmd/controller:./cmd/webhook 72 | ``` 73 | 74 | ### `BP_KEEP_FILES` 75 | The `BP_KEEP_FILES` variable allows to you to specity a path list of files 76 | (including file globs) that you would like to appear in the workspace of the 77 | final image. This will allow you to perserve static assests. 78 | 79 | `BP_KEEP_FILES=assets/*:public/*` 80 | -------------------------------------------------------------------------------- /build.go:

Like the standard 9 | http.ServeMux, mux.Router matches incoming requests against a list of 10 | registered routes and calls a handler for the route that matches the URL 11 | or other conditions. The main features are: 12 | 13 | * Requests can be matched based on URL host, path, path prefix, schemes, 14 | header and query values, HTTP methods or using custom matchers. 15 | * URL hosts, paths and query values can have variables with an optional 16 | regular expression. 17 | * Registered URLs can be built, or "reversed", which helps maintaining 18 | references to resources. 19 | * Routes can be used as subrouters: nested routes are only tested if the 20 | parent route matches. This is useful to define groups of routes that 21 | share common conditions like a host, a path prefix or other repeated 22 | attributes. As a bonus, this optimizes request matching. 23 | * It implements the http.Handler interface so it is compatible with the 24 | standard http.ServeMux. 25 | 26 | Let's start registering a couple of URL paths and handlers: 27 | 28 | func main() { 29 | r := mux.NewRouter() 30 | r.HandleFunc("/", HomeHandler) 31 | r.HandleFunc("/products", ProductsHandler) 32 | r.HandleFunc("/articles", ArticlesHandler) 33 | http.Handle("/", r) 34 | } 35 | 36 | Here we register three routes mapping URL paths to handlers. This is 37 | equivalent to how http.HandleFunc() works: if an incoming request URL matches 38 | one of the paths, the corresponding handler is called passing 39 | (http.ResponseWriter, *http.Request) as parameters. 40 | 41 | Paths can have variables. They are defined using the format {name} or 42 | {name:pattern}. If a regular expression pattern is not defined, the matched 43 | variable will be anything until the next slash. For example: 44 | 45 | r := mux.NewRouter() 46 | r.HandleFunc("/products/{key}", ProductHandler) 47 | r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler) 48 | r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler) 49 | 50 | Groups can be used inside patterns, as long as they are non-capturing (?:re). For example: 51 | 52 | r.HandleFunc("/articles/{category}/{sort:(?:asc|desc|new)}", ArticlesCategoryHandler) 53 | 54 | The names are used to create a map of route variables which can be retrieved 55 | calling mux.Vars(): 56 | 57 | vars := mux.Vars(request) 58 | category := vars["category"] 59 | 60 | Note that if any capturing groups are present, mux will panic() during parsing. To prevent 61 | this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to 62 | "/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably 63 | when capturing groups were present. 64 | 65 | And this is all you need to know about the basic usage. More advanced options 66 | are explained below. 67 | 68 | Routes can also be restricted to a domain or subdomain. Just define a host 69 | pattern to be matched. They can also have variables: 70 | 71 | r := mux.NewRouter() 72 | // Only matches if domain is "www.example.com". 73 | r.Host("www.example.com") 74 | // Matches a dynamic subdomain. 75 | r.Host("{subdomain:[a-z]+}.domain.com") 76 | 77 | There are several other matchers that can be added. To match path prefixes: 78 | 79 | r.PathPrefix("/products/") 80 | 81 | ...or HTTP methods: 82 | 83 | r.Methods("GET", "POST") 84 | 85 | ...or URL schemes: 86 | 87 | r.Schemes("https") 88 | 89 | ...or header values: 90 | 91 | r.Headers("X-Requested-With", "XMLHttpRequest") 92 | 93 | ...or query values: 94 | 95 | r.Queries("key", "value") 96 | 97 | ...or to use a custom matcher function: 98 | 99 | r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool { 100 | return r.ProtoMajor == 0 101 | }) 102 | 103 | ...and finally, it is possible to combine several matchers in a single route: 104 | 105 | r.HandleFunc("/products", ProductsHandler). 106 | Host("www.example.com"). 107 | Methods("GET"). 108 | Schemes("http") 109 | 110 | Setting the same matching conditions again and again can be boring, so we have 111 | a way to group several routes that share the same requirements. 112 | We call it "subrouting". 113 | 114 | For example, let's say we have several URLs that should only match when the 115 | host is "www.example.com". Create a route for that host and get a "subrouter" 116 | from it: 117 | 118 | r := mux.NewRouter() 119 | s := r.Host("www.example.com").Subrouter() 120 | 121 | Then register routes in the subrouter: 122 | 123 | s.HandleFunc("/products/", ProductsHandler) 124 | s.HandleFunc("/products/{key}", ProductHandler) 125 | s.HandleFunc("/articles/{category}/{id:[0-9]+}"), ArticleHandler) 126 | 127 | The three URL paths we registered above will only be tested if the domain is 128 | "www.example.com", because the subrouter is tested first. This is not 129 | only convenient, but also optimizes request matching. You can create 130 | subrouters combining any attribute matchers accepted by a route. 131 | 132 | Subrouters can be used to create domain or path "namespaces": you define 133 | subrouters in a central place and then parts of the app can register its 134 | paths relatively to a given subrouter. 135 | 136 | There's one more thing about subroutes. When a subrouter has a path prefix, 137 | the inner routes use it as base for their paths: 138 | 139 | r := mux.NewRouter() 140 | s := r.PathPrefix("/products").Subrouter() 141 | // "/products/" 142 | s.HandleFunc("/", ProductsHandler) 143 | // "/products/{key}/" 144 | s.HandleFunc("/{key}/", ProductHandler) 145 | // "/products/{key}/details" 146 | s.HandleFunc("/{key}/details", ProductDetailsHandler) 147 | 148 | Note that the path provided to PathPrefix() represents a "wildcard": calling 149 | PathPrefix("/static/").Handler(...) means that the handler will be passed any 150 | request that matches "/static/*". This makes it easy to serve static files with mux: 151 | 152 | func main() { 153 | var dir string 154 | 155 | flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir") 156 | flag.Parse() 157 | r := mux.NewRouter() 158 | 159 | // This will serve files under http://localhost:8000/static/ 160 | r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir)))) 161 | 162 | srv := &http.Server{ 163 | Handler: r, 164 | Addr: "127.0.0.1:8000", 165 | // Good practice: enforce timeouts for servers you create! 166 | WriteTimeout: 15 * time.Second, 167 | ReadTimeout: 15 * time.Second, 168 | } 169 | 170 | log.Fatal(srv.ListenAndServe()) 171 | } 172 | 173 | Now let's see how to build registered URLs. 174 | 175 | Routes can be named. All routes that define a name can have their URLs built, 176 | or "reversed". We define a name calling Name() on a route. For example: 177 | 178 | r := mux.NewRouter() 179 | r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler). 180 | Name("article") 181 | 182 | To build a URL, get the route and call the URL() method, passing a sequence of 183 | key/value pairs for the route variables. For the previous route, we would do: 184 | 185 | url, err := r.Get("article").URL("category", "technology", "id", "42") 186 | 187 | ...and the result will be a url.URL with the following path: 188 | 189 | "/articles/technology/42" 190 | 191 | This also works for host and query value variables: 192 | 193 | r := mux.NewRouter() 194 | r.Host("{subdomain}.domain.com"). 195 | Path("/articles/{category}/{id:[0-9]+}"). 196 | Queries("filter", "{filter}"). 197 | HandlerFunc(ArticleHandler). 198 | Name("article") 199 | 200 | // url.String() will be "http://news.domain.com/articles/technology/42?filter=gorilla" 201 | url, err := r.Get("article").URL("subdomain", "news", 202 | "category", "technology", 203 | "id", "42", 204 | "filter", "gorilla") 205 | 206 | All variables defined in the route are required, and their values must 207 | conform to the corresponding patterns. These requirements guarantee that a 208 | generated URL will always match a registered route -- the only exception is 209 | for explicitly defined "build-only" routes which never match. 210 | 211 | Regex support also exists for matching Headers within a route. For example, we could do: 212 | 213 | r.HeadersRegexp("Content-Type", "application/(text|json)") 214 | 215 | ...and the route will match both requests with a Content-Type of `application/json` as well as 216 | `application/text` 217 | 218 | There's also a way to build only the URL host or path for a route: 219 | use the methods URLHost() or URLPath() instead. For the previous route, 220 | we would do: 221 | 222 | // "http://news.domain.com/" 223 | host, err := r.Get("article").URLHost("subdomain", "news") 224 | 225 | // "/articles/technology/42" 226 | path, err := r.Get("article").URLPath("category", "technology", "id", "42") 227 | 228 | And if you use subrouters, host and path defined separately can be built 229 | as well: 230 | 231 | r := mux.NewRouter() 232 | s := r.Host("{subdomain}.domain.com").Subrouter() 233 | s.Path("/articles/{category}/{id:[0-9]+}"). 234 | HandlerFunc(ArticleHandler). 235 | Name("article") 236 | 237 | // "http://news.domain.com/articles/technology/42" 238 | url, err := r.Get("article").URL("subdomain", "news", 239 | "category", "technology", 240 | "id", "42") 241 | 242 | Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking. 243 | 244 | type MiddlewareFunc func(http.Handler) http.Handler 245 | 246 | Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created). 247 | 248 | A very basic middleware which logs the URI of the request being handled could be written as: 249 | 250 | func simpleMw(next http.Handler) http.Handler { 251 | return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { 252 | // Do stuff here 253 | log.Println(r.RequestURI) 254 | // Call the next handler, which can be another middleware in the chain, or the final handler. 255 | next.ServeHTTP(w, r) 256 | }) 257 | } 258 | 259 | Middlewares can be added to a router using `Router.Use()`: 260 | 261 | r := mux.NewRouter() 262 | r.HandleFunc("/", handler) 263 | r.Use(simpleMw) 264 | 265 | A more complex authentication middleware, which maps session token to users, could be written as: 266 | 267 | // Define our struct 268 | type authenticationMiddleware struct { 269 | tokenUsers map[string]string 270 | } 271 | 272 | // Initialize it somewhere 273 | func (amw *authenticationMiddleware) Populate() { 274 | amw.tokenUsers["00000000"] = "user0" 275 | amw.tokenUsers["aaaaaaaa"] = "userA" 276 | amw.tokenUsers["05f717e5"] = "randomUser" 277 | amw.tokenUsers["deadbeef"] = "user0" 278 | } 279 | 280 | // Middleware function, which will be called for each request 281 | func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler { 282 | return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { 283 | token := r.Header.Get("X-Session-Token") 284 | 285 | if user, found := amw.tokenUsers[token]; found { 286 | // We found the token in our map 287 | log.Printf("Authenticated user %s\n", user) 288 | next.ServeHTTP(w, r) 289 | } else { 290 | http.Error(w, "Forbidden", http.StatusForbidden) 291 | } 292 | }) 293 | } 294 | 295 | r := mux.NewRouter() 296 | r.HandleFunc("/", handler) 297 | 298 | amw := authenticationMiddleware{tokenUsers: make(map[string]string)} 299 | amw.Populate() 300 | 301 | r.Use(amw.Middleware) 302 | 303 | Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to. 304 | 305 | */ 306 | package mux 307 | -------------------------------------------------------------------------------- /integration/testdata/mod/vendor/github.com/gorilla/mux/go.mod: -------------------------------------------------------------------------------- 1 | module github.com/gorilla/mux 2 | 3 | go 1.12 4 | -------------------------------------------------------------------------------- /integration/testdata/mod/vendor/github.com/gorilla/mux/middleware.go: -------------------------------------------------------------------------------- 1 | package mux 2 | 3 | import ( 4 | "net/http" 5 | "strings" 6 | ) 7 | 8 | // MiddlewareFunc is a function which receives an http.Handler and returns another http.Handler. 9 | // Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed 10 | // to it, and then calls the handler passed as parameter to the MiddlewareFunc. 11 | type MiddlewareFunc func(http.Handler) http.Handler 12 | 13 | // middleware interface is anything which implements a MiddlewareFunc named Middleware. 14 | type middleware interface { 15 | Middleware(handler http.Handler) http.Handler 16 | } 17 | 18 | // Middleware allows MiddlewareFunc to implement the middleware interface. 19 | func (mw MiddlewareFunc) Middleware(handler http.Handler) http.Handler { 20 | return mw(handler) 21 | } 22 | 23 | // Use appends a MiddlewareFunc to the chain.
