This can then be used as-is, or given to another third-party library to make cross-origin communication as familiar as a normal ajax request. 42 | 43 | ### Using PPX with jQuery 44 | 45 | The above example can be made simpler using the PPX jQuery plugin: 46 | 47 | ```html 48 | 49 | 50 | 51 | 57 | ``` 58 | 59 | The call `jQuery.proxyAjaxThroughPostMessage()` sets up an [ajax prefilter][] which will automatically proxy requests to foo.com if the host browser doesn't already support CORS. 60 | 61 | ### Using PPX with jQuery and yepnope.js 62 | 63 | You can use PPX with [yepnope.js][] and jQuery, too: 64 | 65 | ```html 66 | 67 | 68 | 81 | ``` 82 | 83 | This will only load PPX's JS code if CORS support isn't detected in the host browser. 84 | 85 | ## Development 86 | 87 | After cloning the git repository and entering its directory, you can start the development server by running: 88 | 89 | python server.py 90 | 91 | This will start two local web servers on ports 9000 and 9001. The functional tests make CORS requests from one to the other to ensure that everything works as expected. 92 | 93 | To start the tests, browse to http://localhost:9000/test/. 94 | 95 | ## Limitations 96 | 97 | Currently, the following features of the [XMLHttpRequest API][] are unsupported: 98 | 99 | * username and password arguments to `open()` 100 | * `getResponseHeader()` (though `getAllResponseHeaders()` is supported) 101 | * `responseXML` 102 | 103 | Several features of the massive [CORS Specification][] are unsupported: 104 | 105 | * Only [simple requests][] can be sent; anything requiring a preflighted request will be rejected for security purposes. 106 | 107 | * Response headers aren't automatically culled down to the [simple response header][] list as prescribed by the spec. 108 | 109 | * Because the `Origin` header can't be set by the same-origin proxied request, PPX sets an `X-Original-Origin` header with the origin of the window making the request. This may be used by servers in place of `Origin`, e.g. to set the appropriate value for `Access-Control-Allow-Origin` in the response. 110 | 111 | * Because the same-origin proxied request can't control whether or not a cookie is transmitted during its request, all cross-origin requests sent should be assumed to have them. Note that we don't currently check the value of `Access-Control-Allow-Credentials` before returning responses, either, so be *very careful* if your site uses cookies. 112 | 113 | ## Similar Projects 114 | 115 | [pmxdr][] provides similar functionality but doesn't provide an XMLHttpRequest API, so it can't necessarily be used as a drop-in replacement. It's also larger than PPX, but supports more features out-of-the-box. 116 | 117 | There's [xdomain](https://github.com/jpillora/xdomain). It doesn't use postMessage. 118 | 119 | ## License 120 | 121 | ``` 122 | The MIT License (MIT) 123 | 124 | Copyright (c) 2011-2014 Atul Varma 125 | 126 | Permission is hereby granted, free of charge, to any person obtaining a copy 127 | of this software and associated documentation files (the "Software"), to deal 128 | in the Software without restriction, including without limitation the rights 129 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 130 | copies of the Software, and to permit persons to whom the Software is 131 | furnished to do so, subject to the following conditions: 132 | 133 | The above copyright notice and this permission notice shall be included in 134 | all copies or substantial portions of the Software. 135 | 136 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 137 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 138 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
