我是 OpcUA 的新手并使用 Open62541 v3.0 - rc2。

我正在尝试连接到 B&R 设备上的 OpcUA 服务器。

当我尝试连接到服务器（使用用户名和密码）时，我收到此消息"No suitable UserTokenPolicy found for the possible endpoints"和此 return-value UA_STATUSCODE_BADINTERNALERROR。

UA_StatusCode statusCode = UA_Client_connect_username(client,endpoint,"user","password");

与UAExpert 的设备连接正常。

阿联酋专家的日志打印以下消息：

安全策略：' http: //opcfoundation.org/UA/SecurityPolicy#None '

UA-Expert 中的连接设置： UA-Expert 中的连接设置

为什么我无法使用以下代码连接到服务器？

#include "open62541.h"

UA_Logger logger = UA_Log_Stdout;

int main(void) {
    const char* endpoint = "opc.tcp://br-automation:4840";

    UA_ClientConfig config = UA_ClientConfig_default;
    UA_Client *client = UA_Client_new(config);

    UA_StatusCode statusCode = UA_Client_connect_username(client,endpoint,"user","password");

    if(statusCode != UA_STATUSCODE_GOOD){
        UA_LOG_ERROR(logger, UA_LOGCATEGORY_CLIENT, "Not connected. Got StatusCode 0x%X",statusCode);
    }
    else{
        UA_LOG_INFO(logger,UA_LOGCATEGORY_CLIENT,"Connected");
    }

    UA_Client_delete(client);

    return statusCode;
}

UA_Client_getEndpoints() 给出以下结果：
