我正在编写一个程序，该程序采用磁力链接，然后使用 RCP 调用远程客户端并在 Deluge 中打开磁力链接。我使用 xmlrpcc4win 作为我的 RPC 库。到目前为止，我可能已经花了一个半小时的时间，大部分时间都在谷歌上搜索这个错误，几乎没有运气。
我的代码如下：
// ConsoleApplication6.cpp : Defines the entry point for the console application.
//
//This program is designed to open magnet links on a remote server using RPC calls.
#include "stdafx.h"
#include "timxmlrpc.h"
#include <iostream>
#include <string>
#include <fstream>
//some basic defines...
#define BASIC_OPPERATION 2
#define SUCCESS 0
#define FAILURE -1
//define funftion prototypes
int callRpc(std::string);
int checkUrl(std::string);
int main(int argc, char* argv[])
{
//convert char* argv[] to string for error handling.
std::string sPassedMagnet = argv[1];
int status;
//chect to see if program is being opened with the correct number of params
if(BASIC_OPPERATION == argc)
{
//check passed link value
checkUrl(sPassedMagnet);
//start RCP call
status = callRpc(sPassedMagnet);
//handle errors
if(SUCCESS != status)
{
std::cout << "Call not successfull" << std::endl;
return FAILURE;
}
//print out a success message
std::cout << "Call made was successfull\n" << std::endl;
std::cout << "Hit Enter..." << std::endl;
std::cin.get();
}
return SUCCESS;
}
int checkUrl(std::string sPassedMagnet){
//nice simple bit of code to check if the link passed in is indeed
//a magnet link, or just some random text that is of no use.
//define local variables
int status;
std::string scheckMag = ("magnet:");
//check to see if string passed in contains 'magnet:'
if (std::string::npos != sPassedMagnet.find(scheckMag))
{
std::cout << "found magnet!\n\n" << std::endl;
std::cout << "Magnet link: " << sPassedMagnet << "\n" << std::endl;
status = SUCCESS;
}
//handle errors if the string does not contain :magnet
else
{
std::cout << "That's not a magnet link...\n" << std::endl;
std::cout << "Press any key...\n" << std::endl;
std::cin.get();
status = FAILURE;
}
return status;
}
int callRpc(std::string sPassedMagnet){
//set client to connect to
//maybe add a scan in from a config file?
XmlRpcClient Connection("localhost:8080/RCP2");
Connection.setIgnoreCertificateAuthority();
// Call: add_torrent_magnet(uri, options):
XmlRpcValue args, result;
args[0] = sPassedMagnet;
args[1] = 1;
// Replace this function name with your own:
if (! Connection.execute("add_torrent_magnet", args, result))
{
std::cout << Connection.getError();
}
//else if (result.getType() == XmlRpcValue::TypeString)
//{
// std::cout << std::string(result);
//}
else
{
std::cout << "Success\n";
}
return SUCCESS;
}
到目前为止，我构建代码时的输出如下：

好的，现在我已经包含了 timxmlrpc.cpp 并将 wininet.lib 链接到我的项目。我现在得到以下...
