我已经上传了一个压缩文件7-zip选项add to .zip只包含一个名为text.txt的文件到这个GitHub repo，我如何可以读取文件text.txt的内容 * 而不 * 写入磁盘？
我正在使用curl将zip文件下载到内存中：

#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;
    }
    
    std::string Download(const std::string& url) 
    {
        CURL* curl_handle;
        CURLcode res;
    
        std::string chunk;
    
        curl_global_init(CURL_GLOBAL_ALL);
    
        curl_handle = curl_easy_init();
        curl_easy_setopt(curl_handle, CURLOPT_URL, url.c_str());
        curl_easy_setopt(curl_handle, CURLOPT_WRITEFUNCTION, WriteMemoryCallback);
        curl_easy_setopt(curl_handle, CURLOPT_WRITEDATA, &chunk);
        curl_easy_setopt(curl_handle, CURLOPT_USERAGENT, "libcurl-agent/1.0");
    
        // added options that may be required
        curl_easy_setopt(curl_handle, CURLOPT_FOLLOWLOCATION, 1L);  // redirects
        curl_easy_setopt(curl_handle, CURLOPT_HTTPPROXYTUNNEL, 1L); // corp. proxies etc.
        curl_easy_setopt(curl_handle, CURLOPT_VERBOSE, 1L); // we want it all
        // curl_easy_setopt(curl_handle, CURLOPT_REDIR_PROTOCOLS, CURLPROTO_HTTP | CURLPROTO_HTTPS);
    
        res = curl_easy_perform(curl_handle);
    
        if(res != CURLE_OK) {
            std::cerr << "curl_easy_perform() failed: " << curl_easy_strerror(res) << '\n';
        } else {
            std::cout << chunk.size() << " bytes retrieved\n";
        }
    
        curl_easy_cleanup(curl_handle);
        curl_global_cleanup();
    
        return chunk;
    }

int _tmain(int argc, _TCHAR* argv[])
{
    std::string link = "https://github.com/R3uan3/test/raw/main/text.zip";
    auto data = Download(link);
}

在搜索能够解压缩内存上的zip的lib时，我找到了这个：libzip（欢迎使用任何lib）。
在搜索示例时，我找到了这个answer，但是他正在将一个zip文件从disk加载到内存中，并阅读它的内容。
如何读取与字符串data上的curl一起下载的zip？
当我在调试器中可视化data的内容时，它显示PK，我尝试将其传递给zip *z，但z返回null

//Open the ZIP archive
        int err = 0;
        zip *z = zip_open(data.c_str(), 0, &err);
    
        //Search for the file of given name
        const char *name = "text.txt";
        struct zip_stat st;
        zip_stat_init(&st);
        zip_stat(z, name, 0, &st);
    
        //Alloc memory for its uncompressed contents
        char *contents = new char[st.size];
    
        //Read the compressed file
        zip_file *f = zip_fopen(z, name, 0);
        zip_fread(f, contents, st.size);
        zip_fclose(f);
