总返回:CURLE_COULDNT_CONNECT,啥情况

漫步者、 2013-12-27 02:11:45

代码如下：

void MyCurLayerTest::initLayer() {

    CURL *curl = 0;

    curl_global_init(CURL_GLOBAL_DEFAULT);

    curl = curl_easy_init();

    if(curl == 0) {

        exit(1);

    } 



    CURLcode code;

    curl_easy_setopt(curl, CURLOPT_URL, "http://www.baidu.com");

    curl_easy_setopt(curl, CURLOPT_HTTPAUTH, CURLAUTH_ANY);

    curl_easy_setopt(curl, CURLOPT_READFUNCTION, &MyCurLayerTest::wirteDatafunction);

    code = curl_easy_perform(curl);//断点的时候，这里的返回值总是CURLE_COULDNT_CONNECT

    curl_easy_cleanup(curl); // 

    curl_global_cleanup();

    switch(code)

    {

    case CURLE_OK:

        CCLOG("CURL_OK\n");

        break;

    default:

        break;

    }

}



size_t MyCurLayerTest::wirteDatafunction(void *ptr_header, size_t infor_size, size_t n_number, void *os_stream) {

    return infor_size * n_number;

}

求指导！

求指导！

是否需要代理，程序能否访问网络，防火墙等[/quote] 访问不了网络，得到的返回值是无法连接上。
