用multipart/form-data卷曲文件上传

我用curl文件上传时遇到了问题。我想在视频托管网站上传我的服务器文件。该脚本需要Content-type: multipart/form-data和Content-type: video/mp4，但我不知道我该怎么做。上传后，文件有content type application/octet-stream。用multipart/form-data卷曲文件上传

这里是脚本

class curl 
{ 
     function __construct($use = 1) 
     { 
     $this->ch = curl_init(); 
       if($use = 1) 
       { 
         curl_setopt ($this->ch, CURLOPT_POST, 1); 
         curl_setopt ($this->ch, CURLOPT_COOKIEJAR, 'cookie.txt'); 
         curl_setopt ($this->ch, CURLOPT_FOLLOWLOCATION, 1); 
         curl_setopt ($this->ch, CURLOPT_RETURNTRANSFER, 1); 
       } 
       else 
       { 
         return 'There is the possibility, that this script wont work'; 
       } 
     } 
     function first_connect($loginform,$logindata) 
     { 
       curl_setopt($this->ch, CURLOPT_URL, $loginform); 
       curl_setopt($this->ch, CURLOPT_POSTFIELDS, $logindata); 
     } 
     function store() 
     { 
       $this->content = curl_exec ($this->ch); 
     } 
     function execute($page) 
     { 
       curl_setopt($this->ch, CURLOPT_URL, $page); 
       $this->content = curl_exec ($this->ch); 
     } 
     function close() 
     { 
       curl_close ($this->ch); 
     } 

     function __toString() 
     { 
     return $this->content; 
     } 

     function upload($file) 
     { 
      curl_setopt($this->ch, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data")); 
      curl_setopt($this->ch, CURLOPT_URL, 'http://uploadsite.com/index.php?act=files&do=upload'); 
      $postdata = array("file[]" => "@/".realpath($file)); 
      echo $postdata; 
      curl_setopt($this->ch, CURLOPT_POSTFIELDS, $postdata); 
      curl_exec ($this->ch); 
     } 
} 


$getit = new curl(); 
$getit->first_connect('http://uploadsite.com/index.php?act=login&login=true','login=true&file_session=&email=xxx%40yahoo.de&password=xxx&upload=Login'); 
$getit->store(); 
$getit->execute('http://uploadsite.com/index.php?act=user&do=home'); 
$getit->upload('Sample.mp4');

而且从livehttpheaders

包替换此行：

$postdata = array("file[]" => "@/".realpath($file));

有：

$postdata = array("file[]" => "@/".realpath($file).";type=video/mp4");

它应该工作。

是的，谢谢你:) – user1488846

我已经使用curl来连接一个web服务，并使用类似的想法上传一个文件，但它没有奏效。与之前的答案不同的原因，所以我将描述我的解决方案;也许我的经验对别人有用。

我有两个问题。第一个是我的Web服务不喜欢文件名中的绝对路径。如果OP代码$文件有一个路径，然后使用：

$postdata = array('file[]' => "@/".realpath($file));

变为：

Content-Disposition: form-data; name="file[]"; filename="/tmp/iy56ham"

和路径产生了错误的请求。所以我不得不使用chdir，basename和dirname以避免在$ postdata中使用路径。

在另一方面，卷曲发一个额外的头，在OP未显示：

Expect: 100-continue

我的web服务不喜欢它（没有叽叽喳喳WS），并将其与回答：

417 Expectation Failed

为了避免卷曲发送该问题的头，你可以使用：

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

所以你设置空预计头卷曲不会被100次继续覆盖。

希望这可以帮助别人......
