ios - pjusa 与 iOS 出现错误 (PJSIP_ENOCREDENTIAL) [状态 = 171101]

Question

我已经构建并将 pjsip 链接到 iOS 项目并尝试连接服务器，但即使在初始连接后它也会给出身份验证错误。

我读了很多地方但没有找到任何解决方案，这是我连接服务器的函数..

startPjsip("1002", "10.26.114.254");

和c函数

int startPjsip(char *sipUser, char* sipDomain)
{
    pj_status_t status;
    // Create pjsua first
    status = pjsua_create();
    if (status != PJ_SUCCESS) error_exit("Error in pjsua_create()", status);

    // Init pjsua
    {
        // Init the config structure
        pjsua_config cfg;
        pjsua_config_default (&cfg);

        cfg.cb.on_incoming_call = &on_incoming_call;
        cfg.cb.on_call_media_state = &on_call_media_state;
        cfg.cb.on_call_state = &on_call_state;

        // Init the logging config structure
        pjsua_logging_config log_cfg;
        pjsua_logging_config_default(&log_cfg);
        log_cfg.console_level = 4;

        // Init the pjsua
        status = pjsua_init(&cfg, &log_cfg, NULL);
        if (status != PJ_SUCCESS) error_exit("Error in pjsua_init()", status);
    }

    // Add UDP transport.
    {
        // Init transport config structure
        pjsua_transport_config cfg;
        pjsua_transport_config_default(&cfg);
        cfg.port = 5060;

        // Add TCP transport.
        status = pjsua_transport_create(PJSIP_TRANSPORT_UDP, &cfg, NULL);
        if (status != PJ_SUCCESS) error_exit("Error creating transport", status);
    }

    // Add TCP transport.
    {
        // Init transport config structure
        pjsua_transport_config cfg;
        pjsua_transport_config_default(&cfg);
        cfg.port = 5060;

        // Add TCP transport.
        status = pjsua_transport_create(PJSIP_TRANSPORT_TCP, &cfg, NULL);
        if (status != PJ_SUCCESS) error_exit("Error creating transport", status);
    }

    // Initialization is done, now start pjsua
    status = pjsua_start();
    if (status != PJ_SUCCESS) error_exit("Error starting pjsua", status);

    // Register the account on local sip server
    {
        pjsua_acc_config cfg;

        pjsua_acc_config_default(&cfg);

        char sipId[MAX_SIP_ID_LENGTH];
        sprintf(sipId, "sip:%s@%s", sipUser, sipDomain);
        cfg.id = pj_str(sipId);

        char regUri[MAX_SIP_REG_URI_LENGTH];
        sprintf(regUri, "sip:%s", sipDomain);
        cfg.reg_uri = pj_str(regUri);

        cfg.cred_info[0].realm = pj_str((char *)"*");

        cfg.cred_info[0].scheme = pj_str((char *)"digest");

        cfg.cred_info[0].username = pj_str((char *)"1002");

        cfg.cred_info[0].data_type = PJSIP_CRED_DATA_EXT_AKA;
        cfg.cred_info[0].data = pj_str((char *)"1234");

        status = pjsua_acc_add(&cfg, PJ_TRUE, &acc_id);
        if (status != PJ_SUCCESS) error_exit("Error adding account", status);
    }

    return 0;
}

这是 pjusa 中的配置结构

 * username and password required to authorize to a specific realm.
 *

 * i.e. realm = pj_str("*");.

    } ext;
};

Answer 1

您正在填充凭据数组但没有告诉 pjsip 它应该使用多少条目。在配置中设置凭据计数(在上述情况下:设置为 1):

/** 
 * Number of credentials in the credential array.
 */
unsigned        cred_count;
