Flask中代码：
@app.route(“/login”) def login(): requestArgs = request.args gLog.debug(‘requestArgs=%s’, requestArgs) # requestArgs=ImmutableMultiDict([(‘next’, u’http://hd.webonn.com/’)]) nextRedirectUrl = requestArgs.get(“next”, “”) gLog.debug(“nextRedirectUrl=%s”, nextRedirectUrl) return redirect(url_for(“wechat_auth”, nextRedirectUrl=nextRedirectUrl)) def login_required(f): @wraps(f) def decorated_function(*args, **kwargs): if g.user is None: return redirect(url_for(‘login’, next=request.url)) return f(*args, **kwargs) return decorated_function @app.route(“/wechat_auth”) def wechat_auth(): if nextRedirectUrl: gLog.debug(“after wechat auth, redirect to nextRedirectUrl=%s”, nextRedirectUrl) # after wechat auth, redirect to nextRedirectUrl=http://hd.webonn.com/ return redirect(nextRedirectUrl) @app.route(‘/join_event/<event_id>’, methods=[‘POST’]) @login_required def join_event(event_id): |
现在的问题是：
当访问：
http://hd.webonn.com/join_event/event-6c316a40-1f14-495a-a7af-80c2febe31df
时，调用到：join_event是POST
但是需要去判断是否登陆：login_required
其中会掉转到login－》wechat_auth
微信授权登录后，再redirect回来
但是等回来的时候的url已经变成了GET了：
导致页面无法访问：
Method Not Allowed The method is not allowed for the requested URL. |
flask redirect post
python – Make a POST request while redirecting in flask – Stack Overflow
python – How to redirect to an external url with parameters and POST method? – Stack Overflow
然后去改为：
@app.route(“/login”, methods=[‘GET’, ‘POST’]) def login(): requestArgs = request.args gLog.debug(‘requestArgs=%s’, requestArgs) # requestArgs=ImmutableMultiDict([(‘next’, u’http://hd.webonn.com/’)]) nextRedirectUrl = requestArgs.get(“next”, “”) gLog.debug(“nextRedirectUrl=%s”, nextRedirectUrl) requestMethod = request.method gLog.debug(“requestMethod=%s”, requestMethod) if requestMethod == “POST”: gLog.debug(“redirect to wechat_auth using code 307 for %s”, nextRedirectUrl) return redirect(url_for(“wechat_auth”, nextRedirectUrl=nextRedirectUrl), code=307) else: return redirect(url_for(“wechat_auth”, nextRedirectUrl=nextRedirectUrl)) @app.route(“/wechat_auth”, methods=[‘GET’, ‘POST’]) # @app.route(“/wechat_auth”) def wechat_auth(): if nextRedirectUrl: gLog.debug(“after wechat auth, redirect to nextRedirectUrl=%s”, nextRedirectUrl) # after wechat auth, redirect to nextRedirectUrl=http://hd.webonn.com/ if requestMethod == “POST”: gLog.debug(“redirect using code 307 for %s”, nextRedirectUrl) return redirect(url_for(nextRedirectUrl), code=307) else: return redirect(url_for(nextRedirectUrl)) else: gLog.debug(“after wechat auth, redirect to default router: index”) return redirect(url_for(“index”)) def login_required(f): @wraps(f) def decorated_function(*args, **kwargs): if g.user is None: requestMethod = request.method requestArgs = request.args gLog.debug(‘when g.user is None, requestMethod=%s, requestArgs=%s’, requestMethod, requestArgs) if requestMethod == “POST”: gLog.debug(“redirect to login using code 307 for %s”, request.url) return redirect(url_for(‘login’, next=request.url), code=307) else: return redirect(url_for(‘login’, next=request.url)) return f(*args, **kwargs) return decorated_function |
然后又出错：
［已解决］Flask中redirect时出错：BuildError Could not build url for endpoint Did you mean show_event instead
最后，其实还是没有完全解决此处的问题：此处因为涉及到多次的跳转
