Solve the problem that php cannot accept post value

When this happens, we need to check the value of the parameter

Content-Type: in our header

php://inputCan read unprocessed POST data. Compared with$HTTP_RAW_POST_DATA, it puts less pressure on memory and does not require specialphp.ini settings.php://inputcannot be used forenctype=multipart/form-data

But I summarized it through code comparison and the results are as follows:

Coentent-Typeis application/x-www-data-urlencodedandmultipart/form-data, PHP will request the data When passed to$_POST

Content-Typetype, the corresponding data in the http request package will be filled in the variable$HTTP_RAW_POST_DATA.

Content-Typeis notmultipart/form-data, PHP will not send http request body data Fill inphp://input, otherwise everything else will work. The length to fill in, specified byContent-Length.

Content-Typeisapplication/x-www-data-urlencoded,php://inputdata will follow$_POSTThe data is consistent.

php://inputis the same as HTTPRAWPOSTDATA∗∗., butphp://input is more efficient than **HTTP_RAW_POST_DATAand does not require configurationphp.ini

httpRequested in theGETformat, thebodybody is empty.

Solution

enable_post_data_reading = On always_populate_raw_post_data = On
