help for newbie!

[Anonymous]

Hi all,

I have problems calling 2.0 getUserInfo.  Here's the specs:

  API 2.0:
     blogger2.getUserInfo([["appkey" => "BIGHONKINGAPPKEY"]
                      ["username" => "stevej"]
                              ["password" => "myfakepassword"]])

The following code always fails:

  XmlRpcValue login, user;
  login[0]["username"] = "uuu";
  login[0]["password"] = "ppp";
  login[0]["appkey"] = "aaa";
  if (c.execute("GetUserInfo", login, user))
    std::cout << "NoSuchMethod call: fault: " << c.isFault() << ", result = " << user << std::endl;
  else
    std::cout << "Error calling 'GetUserInfo'\n";

Any ideas?

Thanks,
J

I can't help without more info. What fails?
What message do you get?

It may be useful to dump more messages from XmlRpc++ using XmlRpc::setVerbosity(5);

I tried using a different method, but I think it's a socket connection problem.  I asked the server developer, and he said the server is up.

XmlRpcClient new client: host http://someServer, port 9000.
XmlRpcClient::execute: method getBlogs (_connectionState 0).
XmlRpcClient::doConnect: fd 100.
XmlRpcClient::close: fd 100.
XmlRpcSource::close: closing socket 100.
XmlRpcSocket::close: fd 100.
XmlRpcSource::close: done closing socket 100.
Error in XmlRpcClient::doConnect: Could not connect to server (error 11004).
Error calling 'getBlogs'
Press any key to continue

The following is my code (modified from HelloClient.cpp):
#include "XmlRpc.h"
#include <iostream>
using namespace XmlRpc;

int main(int argc, char* argv[])
{
  if (argc != 3) {
    std::cerr << "Usage: HelloClient serverHost serverPort\n";
    return -1;
  }
  int port = atoi(argv[2]);
  XmlRpc::setVerbosity(5);

  // Use introspection API to look up the supported methods
  XmlRpcClient c(argv[1], port);
  XmlRpcValue login, blogs;
  login[0]["username"] = "uuu";
  login[0]["password"] = "pppd";
  login[0]["appkey"] = "aaa";
  if (c.execute("getBlogs", login, blogs))
    std::cout << "NoSuchMethod call: fault: " << c.isFault() << ", result = " << blogs << std::endl;
  else
    std::cout << "Error calling 'getBlogs'\n";

  return 0;
}

The following is the method signatures:
blogger2.getBlogs(Struct login) => Array of Struct blogs

The following is the data structure:
Struct 'login':
  username -> String
  password -> String
  appkey -> String
  clientID -> String
  token -> String (not implemented yet. will be addressed with the blogger2.secure.* module)

Struct 'blog':
  blogID -> String
  url -> String
  blogName -> String

Let me add that the first time I ran after re-compile, I got error code 11001.  After that, it was 11004.

What seems to be the problem here?

[Chris Morley]

The errors are from gethostbyname, called from XmlRpcSocket::connect. It attempts to resolve a hostname to an IP address.

11001  is WSAHOST_NOT_FOUND, 11004 is WSANO_DATA (assuming you are on win32 and using winsock2).

Try taking the http:// stuff off your hostname, it is supposed to be a real hostname, not a url.

Thanks for the speedy reply!  Getting rid of "http://" does make it work! 

Keep up the good work.  I am looking forward to new features in future releases.
