［已解决］微信授权出问题：页面无限循环跳转始终无法结束

折腾：

［已解决］微信授权失败：redirect_uri参数错误

之后，又出现另外的问题：

页面一直跳转，无法结束了。

最后终止了服务器，才看到502的错误，页面才停止：

看来是需要写代码，确保正确处理的：

当可以获得code参数，就停止跳转，就继续执行其它的逻辑的。

代码改为：

@app.route("/")

def hello():

requestArgs = request.args

app.logger.debug(‘requestArgs=%s’, requestArgs)

needRedirect = False

paraCode = request.args.get(‘code’, ”)

app.logger.debug(‘paraCode=%s’, paraCode)

if not paraCode :

needRedirect = True

paraState = request.args.get(‘state’, ”)

app.logger.debug(‘paraState=%s’, paraState)

# if not paraState :

# needRedirect = True

if needRedirect:

redirect_uri = "http://hd.webonn.com"

authorize_url = wechat.generate_oauth2_authorize_url(redirect_uri)

app.logger.debug(‘redirect_uri=%s, authorize_url=%s’, redirect_uri, authorize_url)

return redirect(authorize_url)

else:

callbackOkStr = u"回调成功: code=%s, state=%s" % (paraCode, paraState)

return make_response(callbackOkStr)

界面效果：

［总结］

此处的正确逻辑就是去判断，当有回调的url中已经获得了code参数，就不继续跳转了。即可。
