使用 http.request 在 node.js 中获取二进制内容 [英] Getting binary content in node.js with http.request

问题描述

我想从 https 请求中检索二进制数据.

I would like to retrieve binary data from an https request.

我发现了一个类似的问题，使用了请求方法，使用请求获取 Node.js 中的二进制内容，说将 encoding 设置为 null 应该可以，但它不会.

I found a similar question that uses the request method, Getting binary content in Node.js using request, is says setting encoding to null should work, but it doesn't.

options = {
    hostname: urloptions.hostname,
    path: urloptions.path,
    method: 'GET',
    rejectUnauthorized: false,
    encoding: null
};

req = https.request(options, function(res) {
    var data;
    data = "";
    res.on('data', function(chunk) {
        return data += chunk;
    });
    res.on('end', function() {
        return loadFile(data);
    });
    res.on('error', function(err) {
        console.log("Error during HTTP request");
        console.log(err.message);
    });
})

将编码设置为 'binary' 也不起作用

setting encoding to 'binary' doesn't work either

推荐答案

接受的答案对我不起作用(即，将编码设置为二进制)，即使提出问题的用户提到它也不起作用.

The accepted answer did not work for me (i.e., setting encoding to binary), even the user who asked the question mentioned it did not work.

这对我有用，取自:http://chad.pantherdev.com/node-js-binary-http-streams/

http.get(url.parse('http://myserver.com:9999/package'), function(res) {
    var data = [];

    res.on('data', function(chunk) {
        data.push(chunk);
    }).on('end', function() {
        //at this point data is an array of Buffers
        //so Buffer.concat() can make us a new Buffer
        //of all of them together
        var buffer = Buffer.concat(data);
        console.log(buffer.toString('base64'));
    });
});
