如何使用Flask test_client设置请求参数? [英] How to set request args with Flask test_client?

问题描述

我必须测试一个从 request.args 获取某些信息的视图.

I have to test out a certain view that gets certain information from request.args.

我不能嘲笑它，因为视图中的很多东西都使用了request对象.我唯一想到的替代方法是手动设置 request.args .

I can't mock this since a lot of stuff in the view uses the request object. The only alternative I can think of is to manually set request.args.

我可以使用 test_request_context()来做到这一点，例如:

I can do that with the test_request_context(), e.g:

with self.app.test_request_context() as req:
    req.request.args = {'code': 'mocked access token'}
    MyView()

现在，该视图内的请求将具有我设置的参数.但是，我需要调用我的视图，而不仅仅是初始化它，所以我使用以下方法:

Now the request inside this view will have the arguments that I've set. However I need to call my view, not just initialize it, so I use this:

with self.app.test_client() as c:
    resp = c.get('/myview')

但是我不知道如何以这种方式操纵请求参数.

But I don't know how to manipulate the request arguments in this manner.

我已经尝试过了:

with self.app.test_client() as c:
    with self.app.test_request_context() as req:
        req.request.args = {'code': 'mocked access token'}
        resp = c.get('/myview')

但这不会设置 request.args .

推荐答案

将 query_string 参数传递给 c.get ，该参数可以是 dict ， MultiDict 或已编码的字符串.

Pass the query_string argument to c.get, which can either be a dict, a MultiDict, or an already encoded string.

with app.test_client() as c:
    r = c.get('/', query_string={'name': 'davidism'})

测试客户端请求方法将其参数传递给Werkzeug的 EnvironBuilder ，在此进行记录.

The test client request methods pass their arguments to Werkzeug's EnvironBuilder, which is where this is documented.
