带有数据的nodejs httprequest-获取错误getaddrinfo ENOENT [英] nodejs httprequest with data - getting error getaddrinfo ENOENT

问题描述

我看到必须确保从计算机正确解析了DNS，请检出

I see one has to make sure that the DNS is resolved properly from the machine, check out the node documentation to make sure that domain is resolvable.

我正在编写一个基于节点的程序，用户可以在该程序中要求我代表他们执行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httprequest时，它都会我有错

i am writing a nodes based program,in which the user can ask me to do a httprequest on their behalf {off course they provide me with some data, and method to call with} but every time i do a httprequest it gives me an error

getaddrinfo ENOENT 这就是我的代码的样子

getaddrinfo ENOENT this is how my code looks

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…');
}

推荐答案

我已经看到，当您的主机(您通过httpaction传入)前面有方案(即"http://")时，就会发生这种情况.您的主机必须严格是"www.google.com"之类的域名，而不是" http://www.google.com "或"www.google.com/hello-world"或" http://www.google.com /hello-world ".

I've seen this happen when your host (which you pass in as httpaction) has the scheme (so "http://") in front of it. Your host should strictly be the domain like "www.google.com" not "http://www.google.com" or "www.google.com/hello-world" or "http://www.google.com/hello-world".

仅保留域.
