error : redirect_uri_mismatch :: The redirect_uri MUST match the registered callback URL

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。我可以在 Github 和 return 上验证自己回到我的应用程序，但在其显示 404 Not Found Error 和 url 其 http://localhost:5000/login/authorized?error=redirect_uri_mismatch&error_description=The+redirect_uri+MUST+match+the+registered+callback+URL+for+this+application... 中，回调 url 似乎是正确的，因为它是我在 github 上给出的，但它仍然显示 redirect_uri mismatch 。我正在阅读文档 here 并了解到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 ）
你能帮忙的话，我会很高兴。谢谢。

App.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"，其中包含两个视图“/github”和“/github/authorized”。蓝图还配置了 url_prefix 的“/login”，因此您的回调 URL 因此需要 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.
