从mongoose服务器下载tar.gz

I'm trying to download a zipped file through a web GUI connected to a mongoose web server. I figured the naive approach would be to pass the ifstream into the ostream response:

我正在尝试通过连接到mongoose Web服务器的Web GUI下载压缩文件。我认为天真的方法是将ifstream传递给ostream响应:

...
std::stringstream zip_location;
zip_location << path << "/" << timestamp << ".tar.gz";
std::ifstream zip_file(zip_location.str());

if(zip_file){
    // Enters here fine
    request.set_response_content_type("application/x-tar-gz");
    request.add_response_header(new http_header_fields::cache_control_no_cache);
    request.out() << zip_file;
    return true;
}
...

However, the response I get is just an encoded string: MHg3ZjRmYTk5Y2RhYjA=, but I want the browser to download the zip file.

但是,我得到的响应只是一个编码字符串:MHg3ZjRmYTk5Y2RhYjA =,但我希望浏览器下载zip文件。

Its worth noting that I am using an older version of mongoose and I can't seem to find any solutions in the examples.

值得注意的是,我使用的是较旧版本的mongoose,我似乎无法在示例中找到任何解决方案。

Turns out there is indeed a virtual function implemented in the request class that does download a file. All you need to do is pass a string corresponding to the path of the file.

事实证明,确实在请求类中实现了一个下载文件的虚函数。您需要做的就是传递与文件路径对应的字符串。

if(zip_file){
    request.set_response_content_type("application/x-tar-gz");
    request.add_response_header(new http_header_fields::cache_control_no_cache);
    request.send_file(zip_loc.str());
    return true;
}

Hopefully this is helpful.

希望这很有帮助。
