我正在尝试从private GitHub资源库下载一个文件，当前代码：
#include <curl/curl.h>static size_t WriteMemoryCallback(void* contents, size_t size, size_t nmemb, void* userp) {size_t realsize = size * nmemb;auto& mem = *static_cast<std::string*>(userp);mem.append(static_cast<char*>(contents), realsize);return realsize;}void Download(std::string& data, char* url){CURL* curl_handle;CURLcode res;struct curl_slist* slist{};curl_handle = curl_easy_init();curl_easy_setopt(curl_handle, CURLOPT_URL, url);SecureZeroMemory(url, strlen(url));slist = curl_slist_append(slist, "Authorization: token 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");slist = curl_slist_append(slist, "Content-Type: application/json");curl_easy_setopt(curl_handle, CURLOPT_HTTPHEADER, slist);curl_easy_setopt(curl_handle, CURLOPT_TCP_KEEPALIVE, 0);curl_easy_setopt(curl_handle, CURLOPT_WRITEFUNCTION, WriteMemoryCallback);curl_easy_setopt(curl_handle, CURLOPT_WRITEDATA, &data);curl_easy_setopt(curl_handle, CURLOPT_USERAGENT, "libcurl-agent/1.0");curl_easy_setopt(curl_handle, CURLOPT_FOLLOWLOCATION, 1L); // redirects//curl_easy_setopt(curl_handle, CURLOPT_VERBOSE, 1L); // only to debugres = curl_easy_perform(curl_handle);if(res != CURLE_OK)std::cerr << "curl_easy_perform() failed: " << curl_easy_strerror(res) << '\n';curl_easy_cleanup(curl_handle);curl_global_cleanup();}int main(int argc, char* argv[]) {std::string data;Download(data, /* link */);}
这是下载到data的内容：
<!DOCTYPE html><html lang="en" data-color-mode="auto" data-light-theme="light" data-dark-theme="dark" data-a11y-animated-images="system"><head><meta charset="utf-8"><link rel="dns-prefetch" href="https://github.githubassets.com"><link rel="dns-prefetch" href="https://avatars.githubusercontent.com"><link rel="dns-prefetch" href="https://github-cloud.s3.amazonaws.com"><link rel="dns-prefetch" href="https://user-images.githubusercontent.com/"><link rel="preconnect" href="https://github.githubassets.com" crossorigin><link rel="preconnect" href="https://avatars.githubusercontent.com">...
我想问题出在设置授权令牌上，我也试过了：
slist = curl_slist_append(slist, "Authorization: Bearer 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");slist = curl_slist_append(slist, "Content-Type: application/json");

添加授权和接受标头，如下所示：
则呼叫了
并以以下形式提供指向该文件的链接：

您应该包括以下行
否则，在请求中根本不会使用您精心创建的头列表，并且根本不会传输任何身份验证令牌。
此外，由于您使用的是GET请求，因此标头
没有任何意义
就足够了（我非常希望这不是您的实际令牌！如果是，请迅速使其无效并生成一个新令牌！）。
