Question

我使用AngularJS编写Web应用程序，因为CORS问题我使用NodeJS。好吧，当我试图在我的节点中发出请求时，我收到了这个错误：

TypeError: https.request is not a function

我的NodeJS文件（index.js）：

var express = require('express')
var cors = require('cors')
var bodyparser = require('body-parser');
var querystring = require('querystring');
var rootCas = require('ssl-root-cas/latest').create();
rootCas.addFile(__dirname + '/ssl/ovccatastromehes.crt');
const https = require('https').globalAgent.options.ca = rootCas;
var request = require('request');

var app = express()

app.use(bodyparser.urlencoded({extened:false}));
app.use(bodyparser.json()); 
app.use(function (req, res, next) {

    // Website you wish to allow to connect
    res.setHeader('Access-Control-Allow-Origin', 'http://localhost:8080');

    // Request methods you wish to allow
    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');

    // Request headers you wish to allow
    res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type,Authorization');

    // Set to true if you need the website to include cookies in the requests sent
    // to the API (e.g. in case you use sessions)
    res.setHeader('Access-Control-Allow-Credentials', true);

    // Pass to next layer of middleware
    next();
});


app.get('/space/:id', cors(), function (req, res) {
    var soapRequest = '<?xml version="1.0" encoding="utf-8"?>'
            +'<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">'
            +'<soap:Body>'
                +'<Provincia xmlns="http://www.catastro.meh.es/"></Provincia>'
                +'<Municipio xmlns="http://www.catastro.meh.es/"></Municipio>'
                +'<SRS xmlns="http://www.catastro.meh.es/">EPSG:4326</SRS>'
                +'<RefCat xmlns="http://www.catastro.meh.es/">'+req.params.id+'</RefCat>'
            +'</soap:Body></soap:Envelope>';

    var options = {
        host: 'ovc.catastro.meh.es',
        path: '/ovcservweb/ovcswlocalizacionrc/ovccoordenadas.asmx',
        method: 'POST',
        headers : {
            "SOAPAction" : "http://tempuri.org/OVCServWeb/OVCCoordenadas/Consulta_CPMRC",
            "Content-Type": "text/xml; charset=utf-8",
            "Content-Length": Buffer.byteLength(soapRequest)}
    };

    var httpreq = https.request(options, function (response) {
        response.setEncoding('utf8');
        response.on('data', function (chunk) {
            console.log("body: " + chunk);
            res.send(chunk);
        });
        response.on('end', function() {
            //res.send('ok');
        });
    });

    httpreq.write(soapRequest);
    httpreq.end();
});

app.listen(8100, function () {
  console.log('CORS-enabled web server listening on port 8100')
});

我称之为节点的服务：

.factory("catastro", function($http, $sce) {
    /*
     *  INICIALIZACIÓN DE VARIABLES
    */
    var url = 'http://localhost:8100/space/';
    var cat = {};

    /*
     *  FUNCIONES
    */
    // Obtener XML por referencia catastral
    cat.leerReferenciaCatastral = function(rc) {
        var urladd = url + rc;
        return $http.get(urladd)
        .then(function(respuesta) {
            return respuesta.data;
        });
    };

    return cat;
})

这是我第一次使用NodeJS而且我有点迷失了。我搜索过＆＃39; https＆＃39;和请求是一个功能...任何建议？

Answer 1

那是因为你试图调用request对象上的rootCas函数：

const https = require('https').globalAgent.options.ca = rootCas;

换句话说，您可以在rootCas和require('https').globalAgent.options.ca分配https。

相反，试试这个：

const https = require('https');
https.globalAgent.options.ca = rootCas;

的NodeJS。 TypeError：https.request不是函数
