我正在尝试将图像文件发布到服务器。最初我在家里没有代理测试我的脚本,它工作正常。但是当我在学院使用相同的脚本时,它会抛出一些错误。上传图像的功能如下

function upload($filepath,$dir)

{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_VERBOSE, 0);
    curl_setopt($ch, CURLOPT_PROXY, 'localhost:7777');
    curl_setopt($ch, CURLOPT_PROXYUSERPWD, 'ae07b026:kpack');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_URL, 'http://finalytics.in/sites/scrap/uploader.php' );
    $post_array = array(
        "my_file"=>"@".$filepath,
        "upload"=>"Upload",
        "dir"=>$dir
    );
    print_r($post_array);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_array); 
    $response = curl_exec($ch);
    echo $response; 

}

和uploader.php是一个只保存图像的普通文件。

我得到的错误是这样的

        ERROR
    The requested URL could not be retrieved

While trying to process the request:

    POST /sites/scrap/uploader.php HTTP/1.1
    Proxy-Authorization: Basic YWUwN2IwMjY6a3BhY2s=

The following error was encountered:

    Invalid Request 

Some aspect of the HTTP Request is invalid. Possible problems:

    Missing or unknown request method
    Missing URL

    Request is too large

答案 0 :(得分:12)

问题是代理服务机构使用的是“SQUID”。 Squid不支持Expect:100-continue。

所以最后将这个添加到我的选项中

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));

并且一切正常。

如果以上解决方案无效,请添加

curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data",'Expect:  '));
