我已经尝试了几个小时来发出发送文件的POST请求。
I've been trying for several hours to make a POST request that sends a file.
首先尝试一个简单的 file_get_contents（）与流上下文，似乎不工作。
First tried a simple file_get_contents() with stream context, doesn't seem to work. I never get a response back while the GET on a different URL works.
我在网络上搜索了一个HTTP客户端，发现在Packagist上下载了40万次的Guzzle;我决定尝试这种技术。
I searched on the web for an HTTP client and found Guzzle which was downloaded 400k times on Packagist; I decided to try out this technology. Well documented but, alas, getting an error also when posting that damn file.
$request = $client ->post('/files/') ->addPostFields(array('comments' => 'no value')) ->addPostFile('file', 'test.doc') ->setAuth($this->username, $this->password);我花了几个小时的时间浏览网页，发现我有一个417期望失败issue。
It took me hours of reading and scouring the web to find out that I had a "417 Expectation Failed" issue.
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>417 Expectation Failed</title> </head><body> <h1>Expectation Failed</h1> <p>The expectation given in the Expect request-header field could not be met by this server. The client sent<pre> Expect: 100-Continue, 100-Continue </pre> </p><p>Only the 100-continue expectation is supported.</p> </body></html>在网上进行更多搜索后，我最终阅读了Expect：100-continue这是由Guzzle自动发送的，所以我尝试：
After more searching on the web, I ended up reading on the "Expect: 100-continue" header that was sent automatically by Guzzle, so I tried:
$request->removeHeader('expect');我现在遇到错误的请求：
I now end up with a bad request:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>400 Bad Request</title> </head><body> <h1>Bad Request</h1> <p>Your browser sent a request that this server could not understand.<br /> Request header field is missing ':' separator.<br /> <pre> zzle/3.7.3 curl/7.15.5 PHP/5.3.27</pre> </p> </body></html>打印请求标题以找到：missing，i get：
Printing the request headers to find that : missing, i get:
var_dump($request->__toString()); POST /files/ HTTP/1.1 Host: nunc57.qc.bell.ca User-Agent: Guzzle/3.7.3 curl/7.15.5 PHP/5.3.27 Content-Type: multipart/form-data Authorization: Basic bm92YTpzeW5hcHNl现在我真的很抱歉，我希望有人已经找到一个解决这个问题的解决方案。我真的厌倦了所有这些：（
Now I'm really stumped, I hope someone has already found a solution to this issue. I'm getting really tired of all this :(
推荐答案我想知道是否POST到 / files / （带斜杠）可能会导致问题，也许这会强制内部重定向和颠倒Goutte，但不是一个Web浏览器？我试着调整您的页面，使您POST到 / files 或 / files / something 。
I wonder whether POSTing to /files/ (with a trailing slash) might be causing problems. Perhaps this forces an internal redirect and upsets Goutte, but not a web browser? I'd try adjusting your page so that you POST either to /files or /files/something.
可以使用网络浏览器访问目标网址，我还建议您使用浏览器工具记录请求标头，并查看是否有任何标头可以添加到您的Guzzle请求。
If you can POST okay to the target URL using a web browser, I'd also suggest you record the request headers using browser tools, and see if there are any headers that could be added to your Guzzle request.
