MFC http post请求url带参数

MFC之HTTP POST请求（VS2013环境多字符编码） 1、函数调用阅读详情

如题，我需要向web端服务器post一些数据，对方给我的url的后面带个 ?sessionid= (sessionid内容，已提前获取）
我原来是这样

CHttpFile* pFile = pConnection->OpenRequest( CHttpConnection::HTTP_VERB_POST,

 obj + sessionid);

发现总是404
而另外一个url后面没有带sessionid的，其他全部过程一致，完全没有问题。
我猜想sessionid不能这么放，请问该怎么做？
谢谢

你的URL不是用AfxParseURL解析的吗？

不带jsessionid：
AfxParseURL(“http://192.168.1.150:8080/offline/secutity/employee/addMedicare.json”,  ...);
带jsessionid：
AfxParseURL(“http://192.168.1.150:8080/offline/secutity/employee/addMedicare.json?jsessionid=afadafdfad”,  ...);

不是用AfxParseURL解析的，我直接拆分了，在配置文件里配的而且这个函数我也看了，也就得到个server object 和port，如果说唯一能放后面那个jsessionid=*****的那部分，也只有object了（或者就不该放这里），我开始就放object来用的，就是不行

先看你的URL是否正确，其次就是抓包对比一下，看是不是你提交的数据格式有问题

url当然没有问题啦？直接浏览器输服务端那边是能看到的，直接拼接在pstrObjectName后面就是不行
