尝试从 Django 中的 POST 解析`request.body` [英] Trying to parse `request.body` from POST in Django

问题描述

出于某种原因，我无法弄清楚为什么 Django 没有正确处理我的 request.body 内容.

For some reason I cannot figure out why Django isn't handling my request.body content correctly.

它以 JSON 格式发送，查看 Dev Tools 中的 Network 选项卡将其显示为请求负载:

It is being sent in JSON format, and looking at the Network tab in Dev Tools shows this as the request payload:

{creator: "creatorname", content: "postcontent", date: "04/21/2015"}

这正是我希望它被发送到我的 API 的方式.

which is exactly how I want it to be sent to my API.

在 Django 中，我有一个接受这个请求作为参数的视图，只是为了我的测试目的，应该将 request.body["content"] 打印到控制台.

In Django I have a view that accepts this request as a parameter and just for my testing purposes, should print request.body["content"] to the console.

当然，什么都没有打印出来，但是当我打印 request.body 时，我得到了这个:

Of course, nothing is being printed out, but when I print request.body I get this:

b'{"creator":"creatorname","content":"postcontent","date":"04/21/2015"}'

所以我知道我确实发送了一个正文.

so I know that I do have a body being sent.

我尝试过使用 json = json.loads(request.body) 也无济于事.设置该变量后打印 json 也不会返回任何内容.

I've tried using json = json.loads(request.body) to no avail either. Printing json after setting that variable also returns nothing.

推荐答案

在 Python 3.0 到 Python 3.5.x 中，json.loads() 只接受一个 unicode 字符串，所以你必须解码 request.body(这是一个字节字符串)，然后将其传递给 json.loads().

In Python 3.0 to Python 3.5.x, json.loads() will only accept a unicode string, so you must decode request.body (which is a byte string) before passing it to json.loads().

body_unicode = request.body.decode('utf-8')
body = json.loads(body_unicode)
content = body['content']

在 Python 3.6 中，json.loads() 接受字节或字节数组.因此，您不需要解码 request.body(假设它以 UTF-8、UTF-16 或 UTF-32 编码).

In Python 3.6, json.loads() accepts bytes or bytearrays. Therefore you shouldn't need to decode request.body (assuming it's encoded in UTF-8, UTF-16 or UTF-32).
