Question

好吧，我正在尝试使用lib cURL从URL下载.EXE。但是，有错误，如您在上面看到的。

我什么都没尝试。我收到错误消息说fopen不安全，我应该改用fopen_s，但是后来我使用了#define _CRT_SECURE_NO_WARNINGS，这是错误发生的地方


#define _CRT_SECURE_NO_WARNINGS

#include <stdio.h>
#include <stdlib.h>

#include "curl/curl.h"


static size_t write_data(void *ptr, size_t size, size_t nmemb, void *stream)
{
    size_t written = fwrite(ptr, size, nmemb, (FILE *)stream);
    return written;
}

int main(int argc, char *argv[])
{
    CURL *curl_handle;
    static const char *pagefilename = "https://download.expressvpn.xyz/clients/windows/expressvpn_7.1.1.7992.exe";
    FILE *pagefile;

    if (argc < 2) {
        printf("Usage: %s <URL>\n", argv[0]);
        return 1;
    }

    curl_global_init(CURL_GLOBAL_ALL);

    /* init the curl session */
    curl_handle = curl_easy_init();

    /* set URL to get here */
    curl_easy_setopt(curl_handle, CURLOPT_URL, argv[1]);

    /* Switch on full protocol/debug output while testing */
    curl_easy_setopt(curl_handle, CURLOPT_VERBOSE, 1L);

    /* disable progress meter, set to 0L to enable and disable debug output */
    curl_easy_setopt(curl_handle, CURLOPT_NOPROGRESS, 1L);

    /* send all data to this function  */
    curl_easy_setopt(curl_handle, CURLOPT_WRITEFUNCTION, write_data);

    /* open the file */
    pagefile = fopen(pagefilename, "wb");
    if (pagefile) {

        /* write the page body to this file handle */
        curl_easy_setopt(curl_handle, CURLOPT_WRITEDATA, pagefile);

        /* get it! */
        curl_easy_perform(curl_handle);

        /* close the header file */
        fclose(pagefile);
    }

    /* cleanup curl stuff */
    curl_easy_cleanup(curl_handle);

    curl_global_cleanup();

    return 0;
}

我希望它能够通过下载，但没有。它带有错误。
