我正在Python Flask中編寫一個函數來處理多個API的oauth2回調函數。蟒蛇瓶無法合併GET和POST請求

,因爲它代表的功能是:

@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 

然而這會導致生成錯誤:

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

我很困惑,爲什麼發生這種情況,因爲當我更換API變量與字符串'gdrive'沒有錯誤創建,它完美的作品。我在兩種情況下都以相同的方式調用函數(example.com/external_api/gdrive/oauth2callback),我想知道Flask是否無法同時處理POST請求和GET請求,以及如果其他人有同樣的問題?

完整的錯誤日誌低於:

ERROR:app:Exception on /external_api/gdrive/connect [GET]

如果任何人都可以給我在這的指針,這將是偉大的!謝謝!

'return flask.redirect(flask.url_for('gdrive_oauth2callback'))'不會傳遞'api'的值。 – davidism

我認爲燒瓶一定不能失敗,如果你看看這個例子,它可以完美地工作,http://flask.pocoo.org/snippets/62/

我想:

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() 

並能正常工作的崗位和GET請求。我知道這不是明智之舉,但它顯示了問題可能不是什麼。
