Question

我在Python Flask中编写了一个函数来处理多个api的oauth2回调。

现有的功能是：

@app.route('/external_api/<api>/oauth2callback', methods=['POST', 'GET'])
def gdrive_oauth2callback(api):
    toReturn = external_api.APIs[api]['lib'].oauth2callback(os.path.join(APP_OAUTH, str(api + '_id.json')))
    userSession = UserSession()
    userSession.addUserAuth(api)
    return toReturn

但是这会导致构建错误：

raise BuildError(endpoint, values, method)
BuildError: ('gdrive_oauth2callback', {}, None)

我很困惑为什么会发生这种情况，就像我用字符串＆＃39; gdrive＆＃39;替换api变量一样。没有创建错误，它完美地工作。我在两种情况下都以相同的方式调用该函数（example.com/external_api/gdrive/oauth2callback），我想知道Flask是否无法同时处理POST请求和GET请求。同一时间，如果其他人有同样的问题？

完整的错误日志如下：

raise BuildError(endpoint, values, method)
BuildError: ('gdrive_oauth2callback', {}, None) - at=info method=GET path

如果有人能给我任何指示，那就太棒了！谢谢！

我认为烧瓶一定不能失败，如果看一下这个例子，它可以很好地运作，http://flask.pocoo.org/snippets/62/。

我试过了：

from flask import Flask
app = Flask(__name__)

@app.route("/<name>",methods=['POST', 'GET'])
def hello(name):
   return "Hello World!"+name

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

它在发布和获取请求时工作正常。我知道这不是什么，但它表明问题可能不是。
