对不起,伙计们,我有点迷路了。如何在管道时使用console.log response.statusCode
?
var express = require('express');
var path = require('path');
var request = require('request');
var fs = require('fs');
var app = express();
var port = 8000;
var destination = fs.createWriteStream('./downloads/google.html');
var url = "http://www.google.com/";
request(url).pipe(destination)
.on("finish", function() {
console.log("done");
console.log(response.statusCode); // <<<<<<<<<<<<<<<<<<<<<<<<<<<< this
})
.on("error", function(err){
console.log(err);
});
app.listen(port, function(){
console.log('running server on ' + port);
});
答案 0 :(得分:5)
您需要从response
抓住request
事件。它不会出现在管道的finished
事件中。您还应该考虑在管道之前捕获错误。这是您将捕获网络错误的地方。在管道之后你会发现文件错误。
request(url)
.on('response', function(response) {
console.log(response.statusCode) // <--- Here 200
})
.on("error", function(err){
console.log("Problem reaching URL: ", err);
})
.pipe(destination)
.on("finish", function(response) {
console.log("done");
})
.on("error", function(err){
console.log("Problem writing file: ", err);
});
