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: "));
