-------------------------------------------------------------------------------- 1 | HttpRequest 2 | ======= 3 | A simple `HTTP Request` package for golang. `GET` `POST` `DELETE` `PUT` 4 | 5 | 6 | 7 | ### Installation 8 | go get github.com/kirinlabs/HttpRequest 9 | 10 | 11 | ### How do we use HttpRequest? 12 | 13 | #### Create request object use http.DefaultTransport 14 | ```go 15 | resp, err := HttpRequest.Get("http://127.0.0.1:8000") 16 | resp, err := HttpRequest.SetTimeout(5).Get("http://127.0.0.1:8000") 17 | resp, err := HttpRequest.Debug(true).SetHeaders(map[string]string{}).Get("http://127.0.0.1:8000") 18 | 19 | OR 20 | 21 | req := HttpRequest.NewRequest() 22 | req := HttpRequest.NewRequest().Debug(true).SetTimeout(5*time.Second) 23 | resp, err := req.Get("http://127.0.0.1:8000") 24 | resp, err := req.Get("http://127.0.0.1:8000",nil) 25 | resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest") 26 | resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest","address=beijing") 27 | 28 | ``` 29 | 30 | #### Set headers 31 | ```go 32 | req.SetHeaders(map[string]string{ 33 | "Content-Type": "application/x-www-form-urlencoded", 34 | "Connection": "keep-alive", 35 | }) 36 | 37 | req.SetHeaders(map[string]string{ 38 | "Source":"api", 39 | }) 40 | ``` 41 | 42 | #### Set cookies 43 | ```go 44 | req.SetCookies(map[string]string{ 45 | "name":"json", 46 | "token":"", 47 | }) 48 | 49 | OR 50 | 51 | HttpRequest.SetCookies(map[string]string{ 52 | "age":"19", 53 | }).Post() 54 | ``` 55 | 56 | #### Set basic auth 57 | ```go 58 | req.SetBasicAuth("username","password") 59 | ``` 60 | 61 | #### Set timeout 62 | ```go 63 | req.SetTimeout(5) //default 30s 64 | ``` 65 | 66 | #### Transport 67 | If you want to customize the Client object and reuse TCP connections, you need to define a global http.RoundTripper or & http.Transport, because the reuse of the http connection pool is based on Transport. 68 | ```go 69 | var transport *http.Transport 70 | func init() { 71 | transport = &http.Transport{ 72 | DialContext: (&net.Dialer{ 73 | Timeout: 30 * time.Second, 74 | KeepAlive: 30 * time.Second, 75 | DualStack: true, 76 | }).DialContext, 77 | MaxIdleConns: 100, 78 | IdleConnTimeout: 90 * time.Second, 79 | TLSHandshakeTimeout: 5 * time.Second, 80 | ExpectContinueTimeout: 1 * time.Second, 81 | } 82 | } 83 | 84 | func demo(){ 85 | // Use http.DefaultTransport 86 | res, err := HttpRequest.Get("http://127.0.0.1:8080") 87 | // Use custom Transport 88 | res, err := HttpRequest.Transport(transport).Get("http://127.0.0.1:8080") 89 | } 90 | ``` 91 | 92 | #### Keep Alives，Only effective for custom Transport 93 | ```go 94 | req.DisableKeepAlives(false) 95 | 96 | HttpRequest.Transport(transport).DisableKeepAlives(false).Get("http://127.0.0.1:8080") 97 | ``` 98 | 99 | #### Ignore Https certificate validation，Only effective for custom Transport 100 | ```go 101 | req.SetTLSClient(&tls.Config{InsecureSkipVerify: true}) 102 | 103 | HttpRequest.Transport(transport).SetTLSClient(&tls.Config{InsecureSkipVerify: true}).Get("http://127.0.0.1:8080") 104 | ``` 105 | 106 | #### Object-oriented operation mode 107 | ```go 108 | req := HttpRequest.NewRequest(). 109 | Debug(true). 110 | SetHeaders(map[string]string{ 111 | "Content-Type": "application/x-www-form-urlencoded", 112 | }).SetTimeout(5) 113 | resp,err :=

HttpRequest.Debug(true).SetHeaders(map[string]string{}).Get("http://127.0.0.1:8000") 131 | ``` 132 | 133 | 134 | #### Multi parameter 135 | ```go 136 | resp, err := req.Get("http://127.0.0.1:8000?id=10&title=HttpRequest",map[string]interface{}{ 137 | "name": "jason", 138 | "score": 100, 139 | }) 140 | defer resp.Close() 141 | 142 | body, err := resp.Body() 143 | if err != nil { 144 | return 145 | } 146 | 147 | return string(body) 148 | ``` 149 | 150 | 151 | ### POST 152 | 153 | ```go 154 | // Send nil 155 | resp, err :=
