无法理解如何获取特定图片的网址链接

Question

我目前拥有imgur文档中所述的以下代码：

CURL *curl;
    CURLcode res;
    std::string image_hash;
    curl = curl_easy_init();
    if(curl) {
        curl_easy_setopt(curl, CURLOPT_CUSTOMREQUEST, "POST");
        curl_easy_setopt(curl, CURLOPT_URL, "https://api.imgur.com/3/image");
        curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
        curl_easy_setopt(curl, CURLOPT_DEFAULT_PROTOCOL, "https");
        struct curl_slist *headers = NULL;
        headers = curl_slist_append(headers, "Authorization: Client-ID {{***********}}");
        curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
        curl_mime *mime;
        curl_mimepart *part;
        mime = curl_mime_init(curl);
        part = curl_mime_addpart(mime);
        curl_mime_name(part, "image");
        curl_mime_data(part, "C:/Users/HP/Documents/CinderFiles/TestUpload.jpg", CURL_ZERO_TERMINATED);
        curl_easy_setopt(curl, CURLOPT_MIMEPOST, mime);
        res = curl_easy_perform(curl);
        curl_mime_free(mime);
    }

    // Get image url
    curl_easy_cleanup(curl);
    CURLcode res1;
    curl = curl_easy_init();
    if(curl) {
        curl_easy_setopt(curl, CURLOPT_CUSTOMREQUEST, "GET");
        curl_easy_setopt(curl, CURLOPT_URL, "https://api.imgur.com/3/image/{{imageHash}}");
        curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
        curl_easy_setopt(curl, CURLOPT_DEFAULT_PROTOCOL, "https");
        struct curl_slist *headers = NULL;
        headers = curl_slist_append(headers, "Authorization: Client-ID {{***********}}");
        curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
        curl_mime *mime;
        curl_mimepart *part;
        mime = curl_mime_init(curl);
        part = curl_mime_addpart(mime);
        curl_easy_setopt(curl, CURLOPT_MIMEPOST, mime);
        res1 = curl_easy_perform(curl);
        curl_mime_free(mime);
    }
    curl_easy_cleanup(curl);

但是，我不确定如何从curl请求中准确获取网址。有人可以澄清一下吗？
