如果请求超过1450 B，请在PHP中正确读取POST请求参数？ [英] Read POST request parameters properly in PHP for request more than 1450 B?

问题描述

我在api.php脚本上收到POST请求。红色内容使用此代码：

I receive POST request on my api.php script. The content red using this code:

$fp = fopen('php://stdin', 'r');
$all = "";
while($line = fgets($fp, 4096)) { 
    $all .= $line; 
}
echo $all;

如下所示：

Content-Disposition: form-data; name="intro"

O
------------V2ymHFg03ehbqgZCaKO6jy
Content-Disposition: form-data; name="title"

T
------------V2ymHFg03ehbqgZCaKO6jy
Content-Disposition: form-data; name="apiKey"

------------V2ymHFg03ehbqgZCaKO6jy
Content-Disposition: form-data; name="method"

/media/add
------------V2ymHFg03ehbqgZCaKO6jy
Content-Disposition: form-data; name="upload_field"; filename="original_filename.png"
Content-Type: image/png


------------V2ymHFg03ehbqgZCaKO6jy--

正如你所看到的，我得到4个名为intro，title，apiKey和method的参数，以及一个名为original_filename.png的文件1460字节。

As you can see I get 4 parameters called intro, title, apiKey and method, and one file called original_filename.png with size of 1460 bytes.

不幸的是，我的$ _POST数组是空的。当orginal_filename.png小于1450字节时有什么奇怪$ _POST包含所有参数，而stdin是空的。

Unfortunately, my $_POST array is empty. What is weird when orginal_filename.png is less than 1450 bytes $_POST contains all parameters, and stdin is empty.

我希望能够像正常一样阅读这些字段人类PHP来自$ _POST。

I would like to be able to read these fields like normal human PHP being from $_POST.

如何从$ _POST正确读取此POST请求参数？

What to do in order to read this POST request parameters properly from $_POST?

推荐答案

正如我刚刚在手册中看到的那样，enctype =multipart / form-data不提供原始发布数据，但您也可以尝试使用

As I just read in the manual, raw post data is not available with enctype="multipart/form-data" but can you can also try with

$fp = fopen('php://stdin', 'rb');

请注意 b 标志。

此外，请确保php.ini中 always_populate_post_data = On

Also, make sure that always_populate_post_data=On in your php.ini
