node.js - NodeJS套接字挂起超时

Question

这本质上是长时间运行的进程(大约 30 分钟)的超时错误。

如何增加请求的超时时间？我已经尝试过 request.setTimeout(0, console.log); 但它对它没有任何影响。

var request = http.request({
    hostname: 'localhost',
    method: 'POST',
    port: 3000,
    headers: {
        'accept': 'application/json;charset=UTF-8',
    }
}, function(response){
    var body;
    var buffers = [];
    response.on('data', buffers.push.bind(buffers));
    response.on('end', function(){
        try {
            body = Buffer.concat(buffers).toString();
        } catch(error) {console.error(body)}
    });
}).on('error', function(error){ // errors caught in here
    console.error("http error");
    console.error(error);
});

request.setTimeout(0, console.log);

错误:

{ Error: socket hang up
    at createHangUpError (_http_client.js:323:15)
    at Socket.socketOnEnd (_http_client.js:426:23)
    at Socket.emit (events.js:194:15)
    at endReadableNT (_stream_readable.js:1103:12)
    at process._tickCallback (internal/process/next_tick.js:63:19) code: 'ECONNRESET' }

罪魁祸首在服务器端是强大的，并且抛出中止错误

您需要在发出请求之前或发出请求时设置超时。

var request = http.request({
    hostname: 'localhost',
    method: 'POST',
    port: 3000,
    timeout: 0,
    headers: {
        'accept': 'application/json;charset=UTF-8',
    }
}, function(response){
    var body;
    var buffers = [];
    response.on('data', buffers.push.bind(buffers));
    response.on('end', function(){
        try {
            body = Buffer.concat(buffers).toString();
        } catch(error) {console.error(body)}
    });
}).on('error', function(error){ // errors caught in here
    console.error("http error");
    console.error(error);
});
