我看到必须确保从计算机正确解析了DNS，请查看节点文档以确保域是可解析的。

原始问题

我正在编写一个基于节点的程序，用户可以要求我代表他们执行一次httprequest
{当然，他们向我提供一些数据和调用方法}，但是每次我执行一次httprequest，都会给我一个错误

getaddrinfo ENOENT这是我的代码的外观

function makehttprequest(deviceid, httpaction, httppath,methods, actiondata, callback) {
console.log('we are here with httpaction' + httpaction + ' path ' + httppath + ' method ' + methods + ' action data ' + actiondata);
 //do the http post work, get the data, and call the callback function with return data
 var options = {
   host: httpaction,
   port: 80,
   path: httppath,
   method: methods
 };

    try {
      var req = http.request(options, function(res) {
        console.log('STATUS: ' + res.statusCode);
        console.log('HEADERS: ' + JSON.stringify(res.headers));
        res.setEncoding('utf8');
        res.on('data', function (chunk) {
          console.log('BODY: ' + chunk);
        });
      });
    } catch(e) {
      console.log('error as : ' + e.message);
    }

    req.on('error', function(e) {
      console.log('problem with request: ' + e.message);
    });

    // write data to request body
    console.log('writing data to request ..');
    req.write(actiondata);
    console.log('finished writing data to request…');
    req.end();
    console.log('request ended…');
}
