为什么我的Flask应用返回测试状态码为308的响应?

问题描述：

我正在对我的Flask应用进行单元测试.被测试的代码如下:

I'm unit testing my Flask app. The code under test is as follows:

@app.route("/my_endpoint/", methods=["GET"])
def say_hello():
    """
    Greets the user.
    """
    name = request.args.get("name")
    return f"Hello {name}"

测试如下:

class TestFlaskApp:
    def test_my_endpoint(self):
        """
        Tests that my endpoint returns the result as plain text.
        :return:
        """
        client = app.test_client()
        response = client.get("/my_endpoint?name=Peter")
        assert response.status_code == status.HTTP_200_OK
        assert response.data.decode() == "Hello Peter"

错误是:

预期:200实际:308

Expected :200 Actual :308

因此，而不是确定"；(200)我收到了永久重定向"消息，(308)

So instead of "OK" (200) I'm getting a "Permanent Redirect" (308)

答

如果 @ app.route 以斜杠结尾，则还必须在测试中使用斜杠:代替

If the @app.route ends with a slash you must also use the slash in the test: Instead of

response = client.get("/my_endpoint?name=Peter")

使用

response = client.get("/my_endpoint/?name=Peter")

在单元测试中.

这很有意义，但是我花了很长时间才找到.

It makes sense yet took me too long time to find out.
