相信很多人会跟我一样,token验证之后,发送消息给订阅号,没有消息返回。

以下,说一下我辛苦调试得到的解决办法:

首先,token验证:

自己写的token一直验证失败,找了好久,没有发现bug。实在没办法,就用了官方的示例代码。并且通过示例代码调试,发现了一个让我吐血的bug(也不算bug):

token验证貌似要求字符编码格式!!!!

官方的示例代码,直接上传到服务器,token直接过!

把官方示例代码改为UTF-8格式,再上传覆盖,token失败失败!失败!

后来,把自己写的修改为ANSI格式还是token失败!醉了醉了!那只好用官方示例代码。在此,说下,token是一次握手验证,验证过一次就不用了。

 

下面,言归正传,貌似偏题了...orz

token验证之后,直接用官方示例代码,赶紧测试自己的订阅号,结果....发出去的消息就跟泼出去的水一样,什么鬼都没有返回...orz

又各种找bug,各种群问,各种搜索....历经本博主九九八十一的努力,终于找出了问题所在(这里是指我自己开发的,并不包括全部,如果你有不同的bug,欢迎交流):

1、最容易被忽视的一个bug,官方给的示例代码,压根就没调用写好的那个responseMsg()函数!

2、把之前的token代码注释,也就是$wechatObj->valid();这行代码。因为toke验证那段代码会有一个echo $echostr,会把responseMsg()函数里的echo $resultStr;(56行)xml格式混乱,输回给微信服务器就无法识别了(貌似只能识别xml格式,还有json格式)。(token验证是一次握手验证,验证开发者之后,就可以不用了,赶紧让它消失在我们整洁的代码orz...)

3、最恶心的一个bug,还是字符编码问题!orz...xml要求UTF-8编码,所以,把示例代码改回UTF-8编码!这个bug找的让我崩溃!!!

 

下面是我修改后的代码,能正常运行,无bug,需要的可以参考一下
