How does php write the json file sent by the client from the server?

Php: how to write the server to get the json sent from the client? the client uses the libcurl library to send a request to the server over http. how can I write a request not to use the socket PHP to receive the request?

You first
File_put_contents('test.txt ', 'get:'. print_r ($ _ get, 1). 'post: '. print_r ($ _ post, 1 ));
Check the content in test.txt.

If the http get method is used, the data is saved in the $ _ GET array.
If the http post method is used, the data is usually stored in the $ _ POST array.
Note: If the post method does not specify the data type, the submitted data can be obtained through $ HTTP_RAW_POST_DATA.

After finding the data, you can use the json_decode function to convert it to an array or object.

Direct output
Print_r ($ _ POST); ECHO "111 ";
Pint_r ($ _ GET );

Print_r ($ _ POST, 1) I did not see anything directly... The client sends a string.

Who are you looking for directly print_r ($ _ POST? To the client?
Does your client display the code for returning data?

So I want you to send print_r ($ _ POST, 1) to the file so that you can check it.

Get: Array

Post: Array

What I got is this, haha, or nothing... it hurts.

Again
File_put_contents('test.txt ', file_get_contents ('php: // input '));
Look

Sorry, I am not helpful.

Again
File_put_contents('test.txt ', file_get_contents ('php: // input '));
Look

Nothing left ..

Are you sure the client sends data?

Are you sure you want to solve the decoding problem? my client uses c ++ libcurl post.

Why did you not receive any data?

If possible, post the C ++ code snippet.

Curl_easy_cleanup (curl );

} Else {

Return true;

Int allLength; // The total stream length.
Std: vector AllData; // total data

// This function is called when data is returned from the server.
Size_t HHttp: write_data (uint8_t * dataPtr, size_t size, size_t nmemb, void * stream ){

Int len = size * nmemb;

If (len! = 1440 ){
CCLog ("received server data, returned data length: % I", allLength );

} Else {
AllLength + = len;
AllData. push_back (dataPtr );

}

Are you right?
Generally
// Initialize libcurl
CURLcode return_code;
Return_code = curl_global_init (CURL_GLOBAL_WIN32 );
If (CURLE_ OK! = Return_code)
Return 0;
CURL * curl_handle;
CURLcode res;
Curl_handle = curl_easy_init ();
Curl_easy_setopt (curl_handle, CURLOPT_URL, url );
....
You have
CURL * curl;
But no
Curl = curl_easy_init ();
Can the if (curl) branch be included?

The code does run. the connection is successful. what should I do?
