" CURLE_OUT_OF_MEMORY"通过https发布时出错 [英] "CURLE_OUT_OF_MEMORY" error when posting via https

问题描述

我正在尝试编写一个使用libCurl将肥皂请求发布到安全Web服务的应用程序.此Windows应用程序是基于libCurl 7.19.0版构建的，而libCurl版本是7.1opens-0.9.8i构建的.与curl相关的相关代码如下:

I am attempting to write an application that uses libCurl to post soap requests to a secure web service. This Windows application is built against libCurl version 7.19.0 which, in turn, is built against openssl-0.9.8i. The pertinent curl related code follows:

FILE *input_file = fopen(current->post_file_name.c_str(), "rb");
FILE *output_file = fopen(current->results_file_name.c_str(), "wb");
if(input_file && output_file)
{
    struct curl_slist *header_opts = 0;
    CURLcode rcd;

    header_opts = curl_slist_append(header_opts, "Content-Type: application/soap+xml; charset=utf8");
    curl_easy_reset(curl_handle);
    curl_easy_setopt(curl_handle, CURLOPT_NOPROGRESS, 1);
    curl_easy_setopt(curl_handle, CURLOPT_WRITEDATA, output_file);
    curl_easy_setopt(curl_handle, CURLOPT_READDATA, input_file);
    curl_easy_setopt(curl_handle, CURLOPT_URL, fs_service_url);
    curl_easy_setopt(curl_handle, CURLOPT_POST, 1);
    curl_easy_setopt(curl_handle, CURLOPT_HTTPHEADER, header_opts);
    rcd = curl_easy_perform(curl_handle);
    if(rcd != 0)
    {
        current->curl_result = rcd;
        current->curl_error = curl_easy_strerror(rcd);
    }
    curl_slist_free_all(header_opts);
}

当我尝试执行URL时，curl返回一个CURLE_OUT_OF_MEMORY错误，该错误似乎与分配SSL上下文失败有关.有人遇到过这个问题吗?

When I attempt to execute the URL, curl returns an CURLE_OUT_OF_MEMORY error which appears to be related to a failure to allocate an SSL context. Has anyone else encountered this problem before?

推荐答案

经过进一步调查，我发现此错误是由于无法通过调用SSL_library_init()初始化openSSL库而引起的.

After further investigation, I found that this error was due to a failure to initialise the openSSL library by calling SSL_library_init().
