cURL简单文件上传-417预期失败

linux

我对带有cURL的简单文件上传帖子有问题…我做了很多次,但是在这种情况下,我总是从服务器收到“ 417 Expectation
Failed”。当我尝试使用浏览器发布信息时,它可以100%正常运行,但不能使用cURL。

那是我的配置:

我简单的测试形式有效:

<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>

这是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";
    }
?>

我的cURL脚本(image_upload.sh)如下所示:

#!/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
> Expect: 100-continue
> Content-Type: multipart/form-data; boundary=----------------------------e237975526cf
>
< HTTP/1.1 417 Expectation Failed
< Connection: close
< Content-Length: 0
< Date: Thu, 02 Feb 2012 21:29:22 GMT
< Server: lighttpd/1.4.19

我不知道错误在哪里,也许您可​​以识别出它。

也可以使用set opt标头设置进行固定:

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