Php sends json data instances through curl post

Using php curl to send json data is the same as other data in curl post. Next I will summarize several examples of sending json data in curl post, I hope you can better understand the curl post json data.

Example 1

The Code is as follows:

Copy code

$ Data = array ("name" => "Hagrid", "age" => "36 "); $ Data_string = json_encode ($ data );   $ Ch = curl_init ('HTTP: // api. local/rest/users '); Curl_setopt ($ ch, CURLOPT_CUSTOMREQUEST, "POST "); Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ data_string ); Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true ); Curl_setopt ($ ch, CURLOPT_HTTPHEADER, array ( 'Content-Type: application/json ', 'Content-Length: '. strlen ($ data_string )) );   $ Result = curl_exec ($ ch );

Example 2

The Code is as follows:

Copy code

Function http_post_data ($ url, $ data_string ){ $ Ch = curl_init (); Curl_setopt ($ ch, CURLOPT_POST, 1 ); Curl_setopt ($ ch, CURLOPT_URL, $ url ); Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ data_string ); Curl_setopt ($ ch, CURLOPT_HTTPHEADER, array ( 'Content-Type: application/json; charset = UTF-8 ', 'Content-Length: '. strlen ($ data_string )) ); Ob_start (); Curl_exec ($ ch ); $ Return_content = ob_get_contents (); Ob_end_clean (); $ Return_code = curl_getinfo ($ ch, CURLINFO_HTTP_CODE ); Return array ($ return_code, $ return_content ); } $ Url = "http://xx.xx.cn "; $ Data = json_encode (array ('A' => 1, 'B' => 2 )); List ($ return_code, $ return_content) = http_post_data ($ url, $ data );

Example 3

The Code is as follows:

Copy code

$ Data = '{ "Button ":[ { "Type": "click ", "Name": "Today's songs ", "Key": "V1001_TODAY_MUSIC" }, { "Type": "click ", "Name": "Introduction to singers ", "Key": "V1001_TODAY_SINGER" }, { "Name": "menu ", "Sub_button ":[ { "Type": "click ", "Name": "hello word ", "Key": "V1001_HELLO_WORLD" }, { "Type": "click ", "Name": "like us ", "Key": "V1001_GOOD" }] }] }'; $ Ch = curl_init ($ urlcon); // request URL Curl_setopt ($ ch, CURLOPT_CUSTOMREQUEST, "POST "); Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ data); // $ data JSON string Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true ); Curl_setopt ($ ch, CURLOPT_HTTPHEADER, array ('content-Type: application/json', 'content-Length: '. strlen ($ data ))); $ Data = curl_exec ($ ch ); Print_r ($ data); // returned after successful creation: {"errcode": 0, "errmsg": "OK "}

Summary: The Core code is Content-Type: application/json. This is the file format Type.
