卷曲简单的文件上传 - 417预期失败

问题描述

我有一个简单的文件上传后与卷曲的问题...
我做了这么多次，但在这种情况下，我让永诺417预期失败的服务器。
当我尝试后与我的浏览器它的工作原理100％，但有没有卷曲。

i have a problem with a simple file upload post with cURL...i did it so many times but in this case i allways get "417 Expectation Failed" from server.When i try to post with my browser it works 100% but with cURL not.

这就是我的配置：

我简单的测试形式，多数民众赞成如下：

my simple test form thats works:

<form action="http://images.example.com/image_upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="userfile" size="50">
    <input type="submit" name="submit">
</form>

在这里image_upload.php：

here the image_upload.php:

<?php
    $uploaddir = '/var/www/images.example.com/images/';
    $uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
    if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
        echo "File is valid, and was successfully uploaded.\n";
    } else {
        echo "Upload failed";
    }
?>

我卷曲的脚本（image_upload.sh）看起来是这样的：

my cURL script (image_upload.sh) looks like this:

#!/bin/sh

file=$1

result=$(curl -s -L -F "userfile=@$file;type=application/octet-stream;" "http://images.example.com/image_upload.php")

echo $result

和这里的服务器头：

> POST /image_upload.php HTTP/1.1
> User-Agent: curl/7.18.2 (i486-pc-linux-gnu) libcurl/7.18.2 OpenSSL/0.9.8g zlib/1.1.4 libidn/1.8 libssh2/0.18
> Host: images.example.com
> Accept: */*
> Content-Length: 579

< Connection: close
< Content-Length: 0
< Date: Thu, 02 Feb 2012 21:29:22 GMT
< Server: lighttpd/1.4.19

我不知道哪里出错，也许你可以识别它。
谢谢

i don't know where the error is, maybe you can recognize it.Thanks

推荐答案

也可以使用设置选择头设置固定的：

Can also be fixed using set opt header setting:

curl_setopt($curl,CURLOPT_HTTPHEADER,array("Expect:  "));
