Question

我已经完成了this post中的所有回复的print_r（$ _ POST）; ===＆GT;返回空数组的print_r（$ _ SERVER）;

Array ( [HTTP_HOST] => localhost 
        [HTTP_ACCEPT] => */* 
        **[HTTP__CONTENT_TYPE]** => application/json; charset=UTF-8" 
        [CONTENT_LENGTH] => 942
        **[CONTENT_TYPE]** => application/x-www-form-urlencoded 
        [PATH] => /usr/local/bin:/usr/bin:/bin 
        [SERVER_SIGNATURE] => Apache/2.2.14 (Ubuntu) Server at localhost Port 80
        [SERVER_SOFTWARE] => Apache/2.2.14 (Ubuntu) 
        [SERVER_NAME] => localhost 
        [SERVER_ADDR] => 127.0.0.1 
        [SERVER_PORT] => 80 
        [REMOTE_ADDR] => 127.0.0.1 
        [DOCUMENT_ROOT] => /var/www 
        [SERVER_ADMIN] => webmaster@localhost 
        [SCRIPT_FILENAME] => /var/www/slocation.php 
        [REMOTE_PORT] => 50657 
        [GATEWAY_INTERFACE] => CGI/1.1 
        [SERVER_PROTOCOL] => HTTP/1.1 
        [REQUEST_METHOD] => POST 
        [QUERY_STRING] => 
        [REQUEST_URI] => /slocation.php 
        [SCRIPT_NAME] => /slocation.php 
        [PHP_SELF] => /slocation.php 
        [REQUEST_TIME] => 1288466907 
    )

HTTP__CONTENT_TYPE和CONTENT_TYPE有什么区别？

的print_r（$ HTTP_RAW_POST_DATA）; ==＆GT;返回发布的正确数据
的file_get_contents（ 'PHP：//输入'）; ======＆GT;返回正确的数据。

只有$ _POST失败。

这是我的卷曲命令

$url = "http://localhost/slocation.php";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt ($ch, CURLOPT_HTTPHEADER, array('"Content-type: application/json; charset=UTF-8"'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
$result = curl_exec($ch);

要回答我自己的问题，“HTTP__CONTENT_TYPE和CONTENT_TYPE有什么区别？”
如果您看到“HTTP__CONTENT_TYPE”，则很可能意味着您在设置CONTENT-TYPE标头字段时出错。也许，当curl无法识别有效的CONTENT_TYPE值时，错误的值设置为HTTP__CONTENT_TYPE，CONTENT_TYPE采用默认值。

$ _POST在php中为空
