整个想法是在 unix 套接字上使用 LXD RESTful API 进行本地操作。以下代码对于每 2 或 3 个错误运行良好一次。我不知道是否与node.js有关或与lxd api有关。

有错误的输出

请求问题：写 EPIPE { [错误：写 EPIPE] 代码：'EPIPE'，errno：'EPIPE'，系统调用：'write'，地址：未定义}

编码：

var querystring = require('querystring');
var http = require('http'), req, response;

var socketUSD='/var/lib/lxd/unix.socket';

function RestConsume(){ };

RestConsume.prototype._doRequest_=function(httpMethod,pathAPI,data,fnCallBack){
        var dataString = JSON.stringify(data);
        var headers = {};

        if (httpMethod==='GET'){
            pathAPI+='?'+querystring.stringify(data);

        }else{
            headers = {
              'Content-Type': 'application/json',
              'Content-Length': dataString.length
            };
        }
        var options = {
                socketPath: socketUSD,

                method: httpMethod,
                headers: headers
            };

        var req=http.request(options, function (res){
            res.setEncoding('utf-8');

            var resultString="";

            res.on('data',function(data){
                resultString +=data;
            });//end res.on('data')//

            res.on('end',function(){
                console.log(resultString);
                var responseObject = JSON.parse(resultString);
                fnCallBack(resultString);
            });
        });

        req.write(dataString);
        req.end();
        req.on('error', function(e) {
            console.log('Haciendo '+httpMethod);
          console.log('problem with request: ' + e.message);

固定：使用文档.

更准确地说：

http.request(options, callback).end();

现在，代码就像一个魅力。
