我目前正在尝试从 POP3 Gmail 帐户中读取一些邮件，并且我使用 libCurl 库来完成此任务。我创建了一个std::list m_mailsInbox存储该帐户内每封电子邮件的索引。

如您所见，我正在使用提到的索引在此列表中获取，并阅读了存储在std::string dataEmail中的每封邮件。在这个变量中，我有邮件的标题和正文，我需要的是使用 mimetic 库创建一个MimeEntity对象。

这是我当前的代码：

void MailServer::ReadMails(char *username,char *password)
{
    //fetchs into the list one by one
    for(std::list<MailInbox>::iterator it = m_mailsInbox.begin(); it != m_mailsInbox.end(); ++it)   
    {
        struct MemoryStruct chunkMail;
        chunkMail.memory = (char*) malloc(1);  //it will grow as necessary
        chunkMail.size = 0;    //there's no data at this point

        curl_easy_setopt(handle,CURLOPT_USERNAME,username);
        curl_easy_setopt(handle,CURLOPT_PASSWORD,password);

        m_popsAccount = "pop3s://pop.gmail.com:995/" + it->index;   //creates the URL for the email it->index (i.e: 1)

        curl_easy_setopt(handle, CURLOPT_URL, m_popsAccount.c_str());
        curl_easy_setopt(handle, CURLOPT_USE_SSL, CURLUSESSL_ALL); 
        curl_easy_setopt(handle, CURLOPT_SSL_VERIFYPEER, 0); 
        curl_easy_setopt(handle, CURLOPT_SSL_VERIFYHOST, 0); 
        curl_easy_setopt(handle, CURLOPT_HEADER, 1); 
        curl_easy_setopt(handle, CURLOPT_WRITEFUNCTION, WriteMemoryCallback);
        curl_easy_setopt(handle, CURLOPT_VERBOSE, 1); 

        curl_easy_setopt(handle, CURLOPT_WRITEDATA, (void *)&chunkMail);
        //some servers needs this validation
        curl_easy_setopt(handle, CURLOPT_USERAGENT, "libcurl-agent/1.0");

        res = curl_easy_perform(handle); 
        if(res != CURLE_OK)
        {
            fprintf(stderr, "curl_easy_perform() failed: %s\n",
                curl_easy_strerror(res));
        }
        else //everything was fine
        {
            printf("%s\n",chunkMail.memory); //here is the information of the email

            if(ReadMailHeader(chunkMail.memory))
            {
                std::string dataEmail = chunkMail.memory;
                //if returns true, the mail must be saved
                MimeEntity mime; 
                //how i create this object using dataEmail string??                 
            }           
        }

        //frees the data inside
        if(chunkMail.memory)
            free(chunkMail.memory);
    }
}

有什么建议么？

                std::istringstream ss(std::string(chunkMail.memory,m_mailsInbox.at(i).size));

                ios_base::sync_with_stdio(false);   

                //si la funcion retorno true, entonces hay que guardar los datos
                MimeEntity me(ss);

这已经足够了！:)
