Question

我正在尝试使用php cURL将图片上传到特定网站，但我真的不明白我需要发送哪些参数，因为数据看起来有点奇怪。这是我用http分析器得到的
Type : multipart/form-data; boundary=---------------------------182983931283 -----------------------------182983931283 Content-Disposition: form-data; name="file"; filename="Blue hills.jpg" Content-Type: image/jpeg


-----------------------------182983931283
Content-Disposition: form-data; name="file"; filename="Blue hills.jpg"

Content-Type: image/jpeg

Here appears the souce of the image itself like "ÿØÿàÿØÿàÿØÿàÿØÿàÿØÿàÿØÿà" -----------------------------182983931283 Content-Disposition: form-data; name="action" images -----------------------------182983931283 Content-Disposition: form-data; name="anonymous_email"



Y
-----------------------------182983931283
Content-Disposition: form-data; name="site_id"

1
-----------------------------182983931283

and so on other parameters. The issue that I have is that I don't understand what is the boundary, where do I get it from (because it doesn't appear in the html document that generates the POST and how should I make the post . If you would give me a simple example to post the above parameters to http://example.com I will definitely get the trick . 
Currently I'm using the following function to make the post :


   function processPicturesPage($title, $price, $numbedrooms, $description) {        //Set the login parameters and initiate the Login process    
    $fields = array(


"changedImages" => "", 
"site_id" => "1", 
"posting_id" => "", 
"current_live_date" => "", 
"images_loaded" => "", 
"image_actions" => "", 
"title" => $title, 

);
        foreach($fields as $key=>$value)  { 
                $fields_string .= $key.'='.$value.'&'; 
        }
        rtrim($fields_string,'&');
        $URL = "http://www.example.com/cgi-bin/add_posting.pl";
        return $this->processCurlrequest($URL, count($fields), $fields_string);
    }

我有卷曲选项（Cookie等）和网址。

发送多部分数据时，边界用作每个字段之间的分隔符。这些边界由cURL自动创建，您不必担心它们。

curl post picture multipart / form-data，php cURL需要帮助！
