记录一个诡异的bug
将对接oa跳转到会议转写的项目oa/meetingtranslate项目发布到天宫，结果跳转到successPage后报错
这一看就是successPage接口名没对上啊，查了一下代码，没问题啊。
小心起见，我就把successPage的方法请求方式从Post改为Get和POST都可以
发布到测试环境，发现测试环境也报错，也报同样的错。
但是报错之后，我点击地址栏，啥也不改，点击回车，就跳转到好使的页面了
绝了，也就是说，这个请求地址是好使的，那为啥从OA验证中心回来就不好使了呢，绝了
我把这个successPage地址，加入到OA测试环境‘智能中心’那个应用，点击‘智能中心’跳转，跳转回successPage，也是不好使。
完了，完全没有想法了，我以为是天宫的问题，/ai/oa/meetingtran...这个路径找不到，就把整改项目的/oa/请求路径都去掉了，也不好使
把meetingtrans服务的实例地址，放到‘智能中心’这个应用，依旧不好使。
逼的没招了，在本地测一下吧，发现本地也不好使，但是报错：

我擦，进到XXXXController的261行看了一下，发现是successPage里面的请求http方法报错，竟然进入到了successPage方法，我以为根本没进去呢
赶紧debug了一下，发现是successPage方法里面的http请求报错了，所以导致了看起来像successPage这个请求没找到对应的方法。
点击地址栏按回车直接访问的话，因为没传进去参数，所以没走到报错的地方，所以能正常返回错误。
我擦我擦我擦我擦
以后写接口，尽量都加上try catch，防止报错接口就崩了
