运行使用gSOAP创建的web服务客户端时出现SSL错误 我用C++和gSOAP编写了一个用于Web服务编程的客户端。目前，该客户端应调用SendSMS程序，并向指定的号码发送一条sms文本消息，以代替“收件人”，请参见下面的cod。程序运行平稳，但短信未发送。经调查，我发现这条线 int message_status_code=service.SendSMS("https://www.experttexting.com/exptapi/exptsms.asmx","SendSMS",request_packet,request_packet_response);

给出错误代码，该代码的值等于SOAP_SSL_error

为了纠正这个问题，我在使用g++编译时使用了标志-DWITH_OPENSSL，但没有用

请帮我调试这个问题

#include "soapH.h"
#include "ExptTextingAPISoap.nsmap"
#include "soapExptTextingAPISoapProxy.h"

int main(){
   struct soap soap;
   soap_init(&soap);
   string UserID="MY USER Id";
   string PWD="MY PASSWORD";
   string APIKEY="MY API KEY";
   string FROM="FROM";
   string TO="RECEIVER";
   string MSG="MY MESSAGE";
   _ns1__SendSMS* request_packet=soap_new_set__ns1__SendSMS(&soap,&UserID,&PWD,&APIKEY,&FROM,&TO,&MSG);
   _ns1__SendSMSResponse* request_packet_response=soap_new__ns1__SendSMSResponse(&soap);
   ExptTextingAPISoapProxy service(soap);
   int message_status_code=service.SendSMS("https://www.experttexting.com/exptapi/exptsms.asmx","SendSMS",request_packet,request_packet_response);
   service.destroy();
   return 0;
}

在进行服务调用之前，需要提供ssl上下文。如果服务器不需要客户端身份验证，则可以使用下面的代码，否则需要提供客户端证书和密钥

if (soap_ssl_client_context(&soap,
    /* SOAP_SSL_NO_AUTHENTICATION, */ /* for encryption w/o authentication */
    /* SOAP_SSL_DEFAULT | SOAP_SSL_SKIP_HOST_CHECK, */  /* if we don't want the host name checks since these will change from machine to machine */
    SOAP_SSL_DEFAULT,   /* use SOAP_SSL_DEFAULT in production code */
    NULL,       /* keyfile (cert+key): required only when client must authenticate to server (see SSL docs to create this file) */
    NULL,       /* password to read the keyfile */
    "cacert.pem",   /* optional cacert file to store trusted certificates, use cacerts.pem for all public certificates issued by common CAs */
    NULL,       /* optional capath to directory with trusted certificates */
    NULL        /* if randfile!=NULL: use a file with random data to seed randomness */ 
  ))
  { soap_print_fault(&soap, stderr);
    exit(1);
  }

服务器似乎需要SSL连接，但客户端并没有。SSL连接的代码在哪里？我没有SSL连接的代码。我使用SoapClient在php中调用了相同的web服务，它工作了。我不太了解SoapClient，但在这段代码中我没有看到任何SSL握手。你试过SSL握手吗？
