[已解决]Flask中添加了Flask-Login和login_required后访问某个路由出错:405 Method Not Allowed the method is not allowed for the requested URL

之前已经添加了Flask-Login:

[记录]如何在Flask中实现记住微信公众号的用户帐户的登录状态

且给此处的对应的一个路由接口:join_event,添加了login_required:

@app.route(‘/join_event/<int:event_id>’, methods=[‘POST’])
@login_required
def join_event(event_id):
    requestMethod = request.method
    requestArgs = request.args
    gLog.debug(‘requestMethod=%s, requestArgs=%s’, requestMethod, requestArgs)
    gLog.debug(‘type(event_id)=%s, event_id=%s’, type(event_id), event_id)
    eventIdInt = event_id
    curUser = g.user
    gLog.debug(“type(curUser)=%s, curUser=%s”, type(curUser), curUser)

然后内部调试期间,也发现:

已经去实现,跳转到微信授权登录的页面了

但是此处竟然是:

如图(横屏的截图):

搜:

Method Not Allowed the method is not allowed for the requested URL

参考:

后来从log中看到:

所以才知道:

是此处的代码没有写好:

把:

    toAddUserOpenid = request.args.get(“toAddUserOpenid”, “”)
    gLog.debug(“toAddUserOpenid=%s”, toAddUserOpenid)
    (joinedOk, errorStr) = joinToEvent(userOpenid = toAddUserOpenid, eventIdInt = eventIdInt)

改为:

    curUser = g.user
    gLog.debug(“type(curUser)=%s, curUser=%s”, type(curUser), curUser)
    # toAddUserOpenid = request.args.get(“toAddUserOpenid”, “”)
    # gLog.debug(“toAddUserOpenid=%s”, toAddUserOpenid)
    # (joinedOk, errorStr) = joinToEvent(userOpenid = toAddUserOpenid, eventIdInt = eventIdInt)
    (joinedOk, errorStr) = joinToEvent(userOpenid = curUser.openid, eventIdInt = eventIdInt)

即,此处不再用之前的每次把当前的用户的opendi传递来传递去的

而是:

用g.user保存已登录的用户

就可以正常的实现加入活动的功能了。

[总结]

此处是代码写的有问题:

之前已经整合了Flask-Login,且给join_event添加了login_required,但是join_event内部却没有使用g.user,而是获取,已经去掉了没有传递的参数:toAddUserOpenid

导致后续用户找不到,出现405的错误。

后来正常的使用g.user,就可以正常访问页面,正常加入此处的活动了。
