解决方案

我认为问题是 CURLOPT_POSTFIELDS

从PHP手册...

在HTTPPOST操作中发布的完整数据。要发布文件，请使用@前缀一个文件名，并使用完整路径。文件类型可以通过跟随文件名显式指定，其类型为格式; type = mimetype。这个参数可以作为像'para1 = val1& para2 = val2& ...'这样的urlencoded字符串传递，或者作为一个数组，字段名为key，字段数据为value。如果value是一个数组，Content-Type头部将被设置为multipart / form-data。从PHP 5.2.0开始，如果文件使用@前缀传递到此选项，则值必须是一个数组。

http://php.net/manual/en/function.curl-setopt.php

它应该只包含有效载荷，而不是整个标头。

It says the browser sent a request the server could not understand .. I don't exactly understand what went wrong in my PHP code. Can someone please help me understand where I went wrong. Thanks !

<?php
    $url ="http://127.0.0.1/sensor/sens/data.php";
    $xml_data = file_get_contents("/usr/local/www/data/data.xml");
    $header ="POST HTTP/1.0 \r\n";
    $header .="Content-type: text/xml \r\n";
    $header .="Content-length: ".strlen($xml_data)." \r\n";
    $header .="Content-transfer-encoding: text\r\n";
    $header .="Connection: close \r\n\r\n";
    $header .= $xml_data;
    $ch = curl_init();
    curl_setopt ($ch,CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch,CURLOPT_POST,true);
    curl_setopt($ch,CURLOPT_POSTFIELDS,$header);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 4);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header);
    $data = curl_exec($ch);  // if the post is successful , the server will return some data.
    echo $data;

    #$info = curl_getinfo($ch);
    #
    #if(!curl_errno($ch))
    #   echo 'It took '.$info['total_time'].'seconds to send a request to'.$info['url'];
    #
    #   else
    #

    curl_close($ch);
    echo $data;







    ?>

解决方案

I think the problem is with CURLOPT_POSTFIELDS

From the PHP Manual...

The full data to post in a HTTP "POST" operation. To post a file, prepend a filename with @ and use the full path. The filetype can be explicitly specified by following the filename with the type in the format ';type=mimetype'. This parameter can either be passed as a urlencoded string like 'para1=val1&para2=val2&...' or as an array with the field name as key and field data as value. If value is an array, the Content-Type header will be set to multipart/form-data. As of PHP 5.2.0, value must be an array if files are passed to this option with the @ prefix.

http://php.net/manual/en/function.curl-setopt.php

It should hold just the payload and not the entire header.
