Question

我刚开始使用Node.js，我正在尝试使用节点soap扩展来使用SOAP服务。我现在正在使用示例服务调用，但似乎无法启动并运行。

var soap = require('soap');
var fs = require('fs');

reqURL = fs.readFile('www.webservicex.net/stockquote.asmx?WSDL', 'UTF-8', function(err, data){
    if(err) console.log(err)
        soap.createClient(data, function(err, client){
            client.StockQuote.StockQuoteSoap.GetQuote({symbol:'NKE'}, function(err, response){
                if(err) console.log(err);
                    console.log(response);
            });
            console.log('Here is the SOAP sent to ' + data + client.lastrequest);
        });
});

这是我得到的错误：

{ [Error: ENOENT, open 'c:\dev\workspace\WebDevClass\node\www.webservicex.net\st
ockquote.asmx?WSDL']
  errno: -4058,

Answer 1

检查出来

var soap = require("soap");
var url = 'http://www.webservicex.net/stockquote.asmx?WSDL';

reqURL = soap.createClient(url, function(err, client){
    if(err) {
        console.log(err);
        return;
    }

    client.StockQuote.StockQuoteSoap.GetQuote({symbol:'NKE'}, function(err, response){
            if(err) {
                console.log(err);
                return;
            }

            console.log(response);
    });
});

Answer 2

试试这个

SELECT p.id, name, 
   count(distinct lwho.id) delivered_likes, 
   count(distinct lwhom.id) received_likes, 
   count(distinct lmut.id) mutual_likes
FROM people AS p
LEFT JOIN likes AS lwho ON p.id = lwho.who
LEFT JOIN likes AS lwhom ON p.id = lwhom.whom
LEFT JOIN likes AS lmut ON lwhom.who = lmut.whom AND lwhom.whom = lmut.who
GROUP BY p.id,p.name;

从Node.js调用SOAP服务
