request的getReader()和getInputStream()只能调用一次

java1234

baas默认会自己读取一次吗？我需要在baas里发送post请求并且要在请求体中带参数

BeX5中为什么用baas去操作？在biz层的action中可以用HttpClient去操作

baas中的也可以自己用HttpClient看一下

biz用httpclient可以的，baas用就会报这个错， biz太慢了啊，baas快多了

所以就想请教一下是不是因为baas会默认读取一次请求体内容，导致我在baas发post请求会报错！

baas都具体的源码都已经提供的，需要自己跟踪看看，或者就不要用baas提供的方法，自己完全定义

biz和baas一样都是去查数据查数据，如果默认确认是不是biz的分页没设置http://docs.wex5.com/bex5-deploy-question-list-10027/
