我正在尝试使用node.js发出一个简单的HTTP GET请求,但是使用node.js v0.3.4-pre(即截至今天早上从HEAD编译)时遇到了麻烦。这是我的代码:
var cli = require('cli');
var http = require('http');
var url = require('url');
cli.parse();
cli.main(function(args, opts) {
this.debug(args[0]);
var siteUrl = url.parse(args[0]);
var site = http.createClient(siteUrl.port, siteUrl.host);
console.log(siteUrl);
var request = site.request("GET", siteUrl.pathname, {'host' : siteUrl.host})
request.end();
request.on('response', function(response) {
response.setEncoding('utf8');
console.log('STATUS: ' + response.statusCode);
response.on('data', function(chunk) {
console.log("DATA: " + chunk);
});
});
});
这是我得到的错误:
node.js:68
throw e; // process.nextTick error, or 'error' event on first tick
^

最佳答案
发现该错误,除非URL明确命名端口,否则siteUrl.port
将为undefined
。因此,解决方案是:
var site = http.createClient(siteUrl.port || 80, siteUrl.host);
