python-2.7 - 错误:redirect_uri_mismatch::redirect_uri 必须与注册的回调 URL 匹配

Question

所以我正在尝试使用 Github OAuth API 在 Flask 中学习 OAuth，我正在为此使用 flask_dance 库。我能够在 Github 上验证自己并返回到我的应用程序，但在它显示 404 Not Found Error 并且在 url 中它的 http://localhost:5000/login/authorized?error =redirect_uri_mismatch&error_description=The+redirect_uri+MUST+match+the+registered+callback+URL+for+this+application... ，回调 url 似乎是正确的，因为它是我在 github 上给出的，但仍然显示 redirect_uri 不匹配。我正在阅读文档 here并且知道我们可以从请求中删除 redirect_uri 参数，但我不确定该怎么做。(我在 Windows 10 上)
你能帮忙的话，我会很高兴。谢谢。

应用.py

from flask import Flask, redirect, url_for
from werkzeug.contrib.fixers import ProxyFix
from flask_dance.contrib.github import make_github_blueprint, github

app = Flask(__name__)
app.wsgi_app = ProxyFix(app.wsgi_app)
app.secret_key = "supersekrit"
blueprint = make_github_blueprint(
    client_id="xxxxxxxxx",
    client_secret="xxxxxxxx",
)
app.register_blueprint(blueprint, url_prefix="/login")

@app.route("/signup")
def index():
    if not github.authorized:
        return redirect(url_for("github.login"))
    resp = github.get("/user")
    assert resp.ok
    return "You are @{login} on GitHub".format(login=resp.json()["login"])

if __name__ == "__main__":
    app.run(debug=True)

您的回调 URL 不正确 - 应该是 http://localhost:5000/login/github/authorized

Flask-Dance 的文档说代码创建了一个蓝图“github”，其中有两个 View “/github”和“/github/authorized”。该蓝图还配置了“/login”的 url_prefix，因此您的回调 URL 需要为 http://localhost:5000/login/github/authorized。 .

This code makes a blueprint that implements the views necessary to be a consumer in the OAuth dance. The blueprint has two views: /github, which is the view that the user visits to begin the OAuth dance, and /github/authorized, which is the view that the user is redirected to at the end of the OAuth dance. Because we set the url_prefix to be /login, the end result is that the views are at /login/github and /login/github/authorized. The second view is the “authorized callback URL” that you must tell GitHub about when you create the application.
