It support HTTP and HTTPS, the 5 | latter through a hijacking of the request with locally generated SSL certs. 6 | 7 | ## Installtion 8 | 9 | $ npm install -g middlefiddle 10 | 11 | ## Installation via Github 12 | 13 | # Depends on Node 0.6.x 14 | $ git clone git://github.com/mdp/middlefiddle.git 15 | $ cd middlefiddle 16 | $ npm install 17 | $ npm link #If you want to use it globally 18 | 19 | ## Usage 20 | 21 | ### Basic usage 22 | 23 | By default middlefiddle will start logging traffic and modifying 24 | requests based on site specific middleware found in '.middlefiddle/sites' 25 | 26 | You can find an example in 27 | [.middlefiddle/sites](https://github.com/mdp/middlefiddle/tree/master/.middlefiddle/sites) 28 | 29 | # Start middlefiddle with default options 30 | $ middlefiddle 31 | # Proxy will be at port 8080 32 | 33 | ### Using the logger 34 | 35 | $ middlefiddle logger 36 | # Now open http://localhost:8411 37 | 38 | # Only log for a certain URL 39 | $ middlefiddle logger --url google.com 40 | 41 | # Only log certain statuses 42 | $ middlefiddle logger --status 404 43 | 44 | # Only log responses containing text 45 | $ middlefiddle logger --grep "setTimeout" 46 | # Also work with regex 47 | $ middlefiddle logger -r --grep "Mark(Percival)?" 48 | # And case insensitive 49 | $ middlefiddle logger -ri --grep "m@mdp\.im" 50 | 51 | ## Site specific middleware 52 | 53 | MiddleFiddle can alter requests based on the host name. You'll find some examples in 54 | [.middlefiddle/sites](https://github.com/mdp/middlefiddle/tree/master/.middlefiddle/sites) 55 | 56 | Simple add the middleware to your __~/.middlefiddle/sites__ directory, with 57 | the appropriate hostname. For example, __~/.middlefiddle/sites/github.com.coffee'__ 58 | would get injected on any request to github.com 59 | 60 | MiddleFiddle middleware is connect compatible. Anything you can do with 61 | Connect, you can do with middlefiddle middleware. 62 | 63 | ### Examples 64 | ---- 65 | 66 | ### Saving any mp3's from a site 67 | 68 | For example, lets say you want to save all the streamed mp3's from 69 | Soundcloud.com 70 | 71 | *Found in [soundcloud.com.coffee](https://github.com/mdp/middlefiddle/tree/master/.middlefiddle/sites/soundcloud.com.coffee)* 72 | 73 | fs = require 'fs' 74 | module.exports = (Mf) -> 75 | (req, res, next) -> 76 | res.on 'body', -> 77 | if res.headers["content-type"] == 'audio/mpeg' 78 | fileName = req.path.replace(/^[a-zA-Z]/, '').split('.')[0] 79 | path = "#{process.env["HOME"]}/Downloads/soundcloud#{fileName}.mp3" 80 | fs.writeFile path, res.body, -> 81 | console.log "Saved #{res.body.length} bytes to #{path}" 82 | next() 83 | 84 | ### Find and replace any text 85 | 86 | In this case we used the MiddleFiddle helper 'replace' 87 | 88 | *Found in [github.com.coffee](https://github.com/mdp/middlefiddle/tree/master/.middlefiddle/sites/github.com.coffee)* 89 | 90 | module.exports = (Mf) -> 91 | replacement = (string, req, res) -> 92 | contentType = res.headers['content-type'] || '' 93 | if contentType.search(/html/) >= 0 94 | string.replace(/repositories/ig, "suppositories") 95 | else 96 | false 97 | return Mf.replace(replacement) 98 | 99 | ### Modify outbound request headers 100 | 101 | Here we are going to change the user agent to GoogleBot 102 | 103 | *Found in [ft.com.coffee](https://github.com/mdp/middlefiddle/tree/master/.middlefiddle/sites/ft.com.coffee)* 104 | 105 | module.exports = (Mf) -> 106 | # I'm the Google, let me in! 107 | (req, res, next) -> 108 | req.headers['user-agent'] = "GoogleBot" 109 | next() 110 | 111 | ## Web Logging 112 | 113 | By default MiddleFiddle logs all outbound traffic to a web based logger on localhost:8411 114 | 115 | ![Request Logger](http://mdp.github.com/middlefiddle/images/RequestLogger.jpg) 116 | ![Request Logger](http://mdp.github.com/middlefiddle/images/RequestDetails.jpg) 117 | 118 | 119 | ## Configuration 120 | 121 | MiddleFiddle looks for a .middlefiddle directory in the current working directory, or at ~/.middlefiddle. 122 | 123 | Inside you'll find a config.coffee file, https certs, and a sites directory. 124 | 125 | You'll need to add the https certs to you keychain if you want to avoid 126 | the browser warning. The certs are generated on the first launch of 127 | middlefiddle and are therefor unique to each machine. 128 | 129 | 130 | ## HTTPS Hijacking 131 | 132 | When an HTTPS request is first seen, MiddleFiddle generates a certificate for that domain, signs 133 | it with its own generated root cert, and stores the cert for future use in 134 | ~/.middlefiddle/certs 135 | 136 | In order to make this look legit to your browser, you'll need to add the generated 137 | root cert in ~/.middlefiddle/ca.crt to your keychain. This cert is auto generated 138 | just for your machine, so you won't be compromising your browser security. 139 | 140 | ## Things to note 141 | 142 | Connect typically doesn't have a simple way to hijack downstream responses since it's streaming, so 143 | middlefiddle emits events on the response along with writing to the stream. 144 | 145 | res.on 'data', (chunk) -> 146 | console.log chunk.toString() 147 | 148 | res.on 'end', (chunk) -> 149 | console.log chunk.toString() 150 | 151 | res.on 'close', (chunk) -> 152 | console.log "Closed response" 153 | 154 | You've also got a couple helper properties: 155 | 156 | - req.href #=> String: The full requested URL, including the scheme, 157 | host, path, and query params 158 | - req.ssl #=> Boolean: Did it come via SSL? 159 | - req.startTime #=> Datetime: When the request was started 160 | - res.endTime #=> Datetime: I'll let you guess 161 | 162 | ## Modify responses 163 | 164 | ### Modifying the headers 165 | 166 | Response headers can be modified before they are sent to the browser. 167 | Just wait till they're available: 168 | 169 | *Example in [add_csp.coffee](https://github.com/mdp/middlefiddle/tree/master/.middlefiddle/fiddles/add_csp.coffee)* 170 | 171 | ### Replace the response body 172 | 173 | Modifying the a response body means buffering the stream, 174 | waiting for it to finish, then making the replacement and sending it 175 | back downstream. The 'replace' middleware provides this. 176 | 177 | * Usage example in [github.com.coffee](https://github.com/mdp/middlefiddle/tree/master/.middlefiddle/sites/github.com.coffee)* 178 | 179 | ## Testing 180 | 181 | Tests can be run from within the repo 182 | 183 | npm install 184 | npm test 185 | 186 | ## TODO 187 | 188 | - Clean up cert generation 189 | - Expand logging 190 | - Add more middleware 191 | 192 | ## Want to contribute 193 | 194 | Criticism is gladly accepted as long as it's in the form of a pull request. 195 | 196 | ## Development 197 | 198 | MiddleFiddle is written in CoffeeScript. It's set 199 | up with a Cakefile for building files in `src/` to `lib/` and running 200 | tests with nodeunit. There's also a `docs` task that generates Docco 201 | documentation from the source in `src/`. 202 | 203 | Released under the MIT license. 204 | 205 | Mark Percival 206 | -------------------------------------------------------------------------------- /bin/certgen.sh: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | 3 | dir=$3 4 | serial=$2 5 | cert_dir="$dir/certs" 6 | ca_key_file="$dir/ca.key" 7 | ca_crt_file="$dir/ca.crt" 8 | cert_key_file="$cert_dir/$1.key" 9 | cert_csr_file="$cert_dir/$1.csr" 10 | cert_crt_file="$cert_dir/$1.crt" 11 | 12 | if [ ! -e $ca_key_file ];

IT IS EXTREMELY UNWISE TO LOAD CODE FROM SERVERS YOU DO 16 | NOT CONTROL. 17 | 18 | 19 | This file creates a global JSON object containing two methods: stringify 20 | and parse. 21 | 22 | JSON.stringify(value, replacer, space) 23 | value any JavaScript value, usually an object or array. 24 | 25 | replacer an optional parameter that determines how object 26 | values are stringified for objects. It can be a 27 | function or an array of strings. 28 | 29 | space an optional parameter that specifies the indentation 30 | of nested structures. If it is omitted, the text will 31 | be packed without extra whitespace. If it is a number, 32 | it will specify the number of spaces to indent at each 33 | level. If it is a string (such as '\t' or ' '), 34 | it contains the characters used to indent at each level. 35 | 36 | This method produces a JSON text from a JavaScript value. 37 | 38 | When an object value is found, if the object contains a toJSON 39 | method, its toJSON method will be called and the result will be 40 | stringified. A toJSON method does not serialize: it returns the 41 | value represented by the name/value pair that should be serialized, 42 | or undefined if nothing should be serialized. The toJSON method 43 | will be passed the key associated with the value, and this will be 44 | bound to the value 45 | 46 | For example, this would serialize Dates as ISO strings. 47 | 48 | Date.prototype.toJSON = function (key) { 49 | function f(n) { 50 | // Format integers to have at least two digits. 51 | return n < 10 ? '0' + n : n; 52 | } 53 | 54 | return this.getUTCFullYear() + '-' + 55 | f(this.getUTCMonth() + 1) + '-' + 56 | f(this.getUTCDate()) + 'T' + 57 | f(this.getUTCHours()) + ':' + 58 | f(this.getUTCMinutes()) + ':' + 59 | f(this.getUTCSeconds()) + 'Z'; 60 | }; 61 | 62 | You can provide an optional replacer method. It will be passed the 63 | key and value of each member, with this bound to the containing 64 | object. The value that is returned from your method will be 65 | serialized. If your method returns undefined, then the member will 66 | be excluded from the serialization. 67 | 68 | If the replacer parameter is an array of strings, then it will be 69 | used to select the members to be serialized. It filters the results 70 | such that only members with keys listed in the replacer array are 71 | stringified. 72 | 73 | Values that do not have JSON representations, such as undefined or 74 | functions, will not be serialized. Such values in objects will be 75 | dropped; in arrays they will be replaced with null. You can use 76 | a replacer function to replace those with JSON values. 77 | JSON.stringify(undefined) returns undefined. 78 | 79 | The optional space parameter produces a stringification of the 80 | value that is filled with line breaks and indentation to make it 81 | easier to read. 82 | 83 | If the space parameter is a non-empty string, then that string will 84 | be used for indentation. If the space parameter is a number, then 85 | the indentation will be that many spaces. 86 | 87 | Example: 88 | 89 | text = JSON.stringify(['e', {pluribus: 'unum'}]); 90 | // text is '["e",{"pluribus":"unum"}]' 91 | 92 | 93 | text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); 94 | // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' 95 | 96 | text = JSON.stringify([new Date()], function (key, value) { 97 | return this[key] instanceof Date ? 98 | 'Date(' + this[key] + ')' : value; 99 | }); 100 | // text is '["Date(---current time---)"]' 101 | 102 | 103 | JSON.parse(text, reviver) 104 | This method parses a JSON text to produce an object or array. 105 | It can throw a SyntaxError exception. 106 | 107 | The optional reviver parameter is a function that can filter and 108 | transform the results. It receives each of the keys and values, 109 | and its return value is used instead of the original value. 110 | If it returns what it received, then the structure is not modified. 111 | If it returns undefined then the member is deleted. 112 | 113 | Example: 114 | 115 | // Parse the text. Values that look like ISO date strings will 116 | // be converted to Date objects. 117 | 118 | myData = JSON.parse(text, function (key, value) { 119 | var a; 120 | if (typeof value === 'string') { 121 | a = 122 | /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value); 123 | if (a) { 124 | return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], 125 | +a[5], +a[6])); 126 | } 127 | } 128 | return value; 129 | }); 130 | 131 | myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) { 132 | var d; 133 | if (typeof value === 'string' && 134 | value.slice(0, 5) === 'Date(' && 135 | value.slice(-1) === ')') { 136 | d = new Date(value.slice(5, -1)); 137 | if (d) { 138 | return d; 139 | } 140 | } 141 | return value; 142 | }); 143 | 144 | 145 | This is a reference implementation.
