XmlRPC入门_基于C的服务端、客户端

以下客户端与服务端的代码内容为官网给出的示例，此处拷贝记录，了解基础使用方式。

1、服务端

#include <iostream>
#include <winsock2.h>
#include <windows.h>

#include "xmlrpc-c/base.h"
#include "xmlrpc-c/server.h"
#include "xmlrpc-c/server_abyss.h"
#include <direct.h>
#include <stdio.h>
#include <stdlib.h>
#include <direct.h>
static xmlrpc_value *sample_add(xmlrpc_env * const envP,
    xmlrpc_value * const paramArrayP,
    void *         const serverInfo,
    void *         const channelInfo) {

    xmlrpc_int32 x, y, z;

    /* Parse our argument array. */
    xmlrpc_decompose_value(envP, paramArrayP, "(ii)", &x, &y);
    if (envP->fault_occurred)
        return NULL;

    /* Add our two numbers. */
    z = x + y;

    /* Sometimes, make it look hard (so client can see what it's like
       to do an RPC that takes a while).
    */
    if (y == 1)
        Sleep(5);

    /* Return our result. */
    return xmlrpc_build_value(envP, "i", z);
}

int main() {
    struct xmlrpc_method_info3 const methodInfo = {
        /* .methodName     = */ "sample.add",
        /* .methodFunction = */ &sample_add,
    };
    xmlrpc_server_abyss_parms serverparm;
    xmlrpc_registry * registryP;
    xmlrpc_env env;

    xmlrpc_env_init(&env);

    registryP = xmlrpc_registry_new(&env);
    if (env.fault_occurred) {
        printf("xmlrpc_registry_new() failed.  %s\n", env.fault_string);
        exit(1);
    }

    xmlrpc_registry_add_method3(&env, registryP, &methodInfo);
    if (env.fault_occurred) {
        printf("xmlrpc_registry_add_method3() failed.  %s\n",
            env.fault_string);
        exit(1);
    }

    serverparm.config_file_name = NULL;   /* Select the modern normal API */
    serverparm.registryP = registryP;
    serverparm.port_number = 8080;
    serverparm.log_file_name = "/tmp/xmlrpc_log";

    printf("Running XML-RPC server...\n");

    xmlrpc_server_abyss(&env, &serverparm, XMLRPC_APSIZE(log_file_name));
    if (env.fault_occurred) {
        printf("xmlrpc_server_abyss() failed.  %s\n", env.fault_string);
        exit(1);
    }
    /* xmlrpc_server_abyss() never returns unless it fails */

    return 0;
}

 2、客户端

#include <iostream>
#include "xmlrpc-c/base.h"
#include "xmlrpc-c/client.h"
#include "xmlrpc-c/client_global.h"
#include "xmlrpc-c/util.h"

static void dieIfFaultOccurred(xmlrpc_env * const envP) {
    if (envP->fault_occurred) {
        fprintf(stderr, "ERROR: %s (%d)\n",
            envP->fault_string, envP->fault_code);
        exit(1);
    }
}

int main(int const argc, const char ** const argv) {

    xmlrpc_env env;
    xmlrpc_value * resultP;
    xmlrpc_int32 sum;
    const char * const serverUrl = "http://localhost:8080/RPC2";
    const char * const methodName = "sample.add";

    if (argc - 1 > 0) {
        fprintf(stderr, "This program has no arguments\n");
        exit(1);
    }

    /* Initialize our error-handling environment. */
    xmlrpc_env_init(&env);

    /* Create the global XML-RPC client object. */
    xmlrpc_client_init2(&env, XMLRPC_CLIENT_NO_FLAGS, NAME, VERSION, NULL, 0);
    dieIfFaultOccurred(&env);

    printf("Making XMLRPC call to server url '%s' method '%s' "
        "to request the sum "
        "of 5 and 7...\n", serverUrl, methodName);

    /* Make the remote procedure call */
    resultP = xmlrpc_client_call(&env, serverUrl, methodName,
        "(ii)", (xmlrpc_int32)5, (xmlrpc_int32)7);
    dieIfFaultOccurred(&env);

    /* Get our sum and print it out. */
    xmlrpc_read_int(&env, resultP, &sum);
    dieIfFaultOccurred(&env);
    printf("The sum is %d\n", sum);

    /* Dispose of our result value. */
    xmlrpc_DECREF(resultP);

    /* Clean up our error-handling environment. */
    xmlrpc_env_clean(&env);

    /* Shutdown our XML-RPC client library. */
    xmlrpc_client_cleanup();

    return 0;
