为什么PUT 403显示为Aborted？

问题描述

我做了一个虚拟的django视图，接受 PUT 请求：

I've made a dummy django view that accepts PUT requests:

# urls.py
url(r'^put/.*$', 'put', name='put'),

# views.py
def put(request):
    print request.method
    return HttpResponse()

现在，当我尝试对视图进行 PUT xhr调用时，它返回403：

Now, when I try to make a PUT xhr call to the view, it returns a 403:

（为什么它返回403，我现在不在乎）。真正的问题是：

(why it returns 403, I don't care right now). The REAL problem is this:

XHR调用返回状态0（已中止？！），即使实际响应为403，包含内容（通知内容长度为156400）。

The XHR call returns status 0 (aborted?!), even if the real response was a 403, with content (notice 156400 content length).

为什么不显示403响应？

编辑： PUT 请求如下：

var xhr = new XMLHttpRequest();
var path = "/" + u.settings.key;
path += "?partNumber=" + (chunk + 1) + "&uploadId=" + u.upload_id;

var method = "PUT";
var authorization = "AWS " + u.settings.access_key + ":" + signature;
var blob = u.file.slice(start, end); // mozSlice / webkitSlice, depending on browser
xhr.upload.addEventListener("progress", progress_handler);
xhr.addEventListener("readystatechange", handler);
xhr.addEventListener("error", error_handler);
xhr.addEventListener("timeout", error_handler);

xhr.open(method, /*u.settings.host*/ "http://localhost:8000/put" + path, true);

xhr.setRequestHeader("x-amz-date", date);
xhr.setRequestHeader("Authorization", authorization);
xhr.setRequestHeader("Content-Type", u.settings.content_type);
xhr.setRequestHeader("Content-Disposition", "attachment; filename=" + u.file.name);

xhr.send(blob);

推荐答案

我认为浏览器假设它是一个交叉域请求收到403时意味着禁止访问。这就是浏览器没有将数据处理回发出请求的javascript代码的原因。服务器应为所有响应发送Action-Control-Allow-Origin标头。

I think browser is assuming that it is a cross-domain request when it receives 403 which means forbidden access. That's the reason why browser is not handling data back to the javascript code that made the request. Server should send 'Action-Control-Allow-Origin' header for all the responses.
