PHP gets data in different formats in HTTP POST

The POST method in the HTTP protocol has multiple formats of data protocols, which are identified by different Content-types in the HTTP header. Commonly used ones are

application/x-www-form- urlencoded, which is the most common, is the format of the from form. In the HTTP head, it is Content-Type: application/x-www-form-urlencoded.

multipart/form-data, this is used to upload files, in the HTTP head is Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

Raw This is not particularly commonly used. The transmitted data has only one segment in the HTTP body and is not stored in the form of key-value pairs. In the HTTP head, it is Content-Type: application/json, Content-Type: text,Content-Type: application/xml,Content-Type: text/xml, etc. For

Content-Type: application/x-www-form-urlencoded

The data of this form can be obtained directly in php using $_POST['name']. There is nothing Special

Content-Type: multipart/form-data;

Data in this format can be obtained by using $_POST['name'] in php Data can be obtained using $_FILES['file'].For data in Raw format, it cannot be obtained using the above two methods, and other methods need to be used.

1. Use

file_get_contents("php://input")

Get; write a simple php file to test it<pre class="brush:php;toolbar:false">&lt;?php $test=file_get_contents(&quot;php://input&quot;); echo $test;</pre>Test it with postman

No problem, you can receive it

2. Use

$GLOBALS['HTTP_RAW_POST_DATA']

Receive<pre class="brush:php;toolbar:false">&lt;?php $test=$GLOBALS[&amp;#39;HTTP_RAW_POST_DATA&amp;#39;]; echo $test;</pre>Test it with postman

Damn it, something went wrong, the prompt was not found

HTTP_RAW_POST_DATA

What the hell is this array index? After some Google, I saw this paragraph on the official website of PHP Words

It turns out that

HTTP_RAW_POST_DATA

has been abandoned in php5.6 and has been deleted in php7.0 and later versions. I use The php version is 7.2, something must be wrongOkay, then just use

file_get_contents("php://input")

Get it In actual development, frameworks are generally used. I use thinkphp more. In tp5.0, you can use the getInput() function of Request to obtain the data in Raw

<?php

namespace app\index\controller;

use think\Request;

class Index
{
    public function index(Request $request)
    {
        echo $request->getInput();
    }
}

Test it

No problem, you can obtain it normally
