用multipart/form-data卷曲文件上传
问题描述:
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。

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......
是的,谢谢你:) – user1488846
