xmlrpc++谁用过？

大爷想要时光机 2009-07-08 04:26:12

怎么给远程调用methodCall加参数呢，也就是客户端的接口execute中，第二个参数是给这个xmlrpc调用带上参数的，参数有数组和结构体，利用XmlRpcValue这个类来传，具体是怎么传递呢？

XmlRpcValue可以当做数据或者结构来用，支持[]操作符。
例如：params可以使用
params[0]["Name"] = "ZhangSan";
params[0]["Age"]=12;

不过我用测试程序没问题，但是把服务器放在多线程程序中的非GUI线程运行，就不稳定，有时候能行，有时候不行，暂时还没解决。

里面哪个接口不清楚的话直接点里面的链接即可！

希望能对你有所帮助，谢谢！

这个基本上没用，我看的就是官方的文档，只有类的声明和成员函数的原型，没有demo，不知道怎么调用

bool XmlRpcClient::execute  ( const char *  method,  

  XmlRpcValue const &  params,  

  XmlRpcValue &  result   

 )    



Execute the named procedure on the remote server. 



Parameters:

 method  The name of the remote procedure to execute  

 params  An array of the arguments for the method  

 result  The result value to be returned to the client  



Returns:

true if the request was sent and a result received (although the result might be a fault).

Currently this is a synchronous (blocking) implementation (execute does not return until it receives a response or an error). Use isFault() to determine whether the result is a fault response.
