|
|

<h2>POST</h2>
|
|
<div>When sending data via a POST or PUT request, two common formats (specified via the Content-Type header) are:</div>
|
|
<ul><li><div>application/json</div></li><li><div>application/x-www-form-urlencoded</div></li></ul>
|
|
<div>Many APIs will accept both formats, so if you're using curl at the command line, it can be a bit easier to use the form urlencoded format instead of json because</div>
|
|
<ul><li><div>the json format requires a bunch of extra quoting</div></li><li><div>curl will send form urlencoded by default, so for json the Content-Type header must be explicitly set</div></li></ul>
|
|
<div>This gist provides examples for using both formats, including how to use sample data files in either format with your curl requests.</div>
|
|
<h2>curl usage</h2>
|
|
<div>For sending data with POST and PUT requests, these are common curl options:</div>
|
|
<ul><li><div>request type</div></li><ul><li><div>-X POST</div></li><li><div>-X PUT</div></li></ul><li><div>content type header</div></li><li><div>-H "Content-Type: application/x-www-form-urlencoded"</div></li><li><div>-H "Content-Type: application/json"</div></li><li><div>data</div></li><ul><li><div>form urlencoded: -d "param1=value1&m2=value2" or -d @data.txt</div></li><li><div>json: -d '{"key1":"value1", "key2":"value2"}' or -d @data.json</div></li></ul></ul>

<h3>POST application/x-www-form-urlencoded</h3>
