异常getaddrinfo enotfound
在看NodeJS开发指南这本书时,书中的一个例子,讲解http.request的.代码如下:
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
1 var http = require('http'); 2 var querystring = require('querystring'); 3 var contents = querystring.stringify({ 4 name: 'byvoid', 5 email: 'byvoid@byvoid.com', 6 address: 'Zijing 2#, Tsinghua University', 7 }); 8 var options = { 9 host: 'www.byvoid.com', 10 path: '/application/node/post.php', 11 method: 'POST', 12 headers: { 13 'Content-Type': 'application/x-www-form-urlencoded', 14 'Content-Length' : contents.length 15 } 16 }; 17 var req = http.request(options, function(res) { 18 res.setEncoding('utf8'); 19 res.on('data', function (data) { 20 console.log(data); 21 }); 22 }); 23 req.write(contents); 24 req.end();
在运行时会出现以下的error:
events.js:72
throw er;// Unhandled 'error' event
^
Error: getaddrinfo ENOTFOUND
at errnoException (dns.js:37:11)
at Object.onanswer [as oncomplete](dns.js:124:16)
随后,查看了官方关于http.request的函数说明.
将代码host: 'www.byvoid.com',修改为 hostname:url.parse( 'www.byvoid.com').hostname.
即可成功运行.
