在NodeJS中使用node-soap时出错

Question

this.getSoap = function (request, response) {
var soap = require('node-soap');

var url = 'http://identificacion.uci.cu/servicios/v5/servicios.php';
var args = { IdExpediente: '016381' };

soap.createClient(url, function (err, client) {
    client.ObtenerFotoDadoIdExpediente(args, function (err, result) {
        if (err) {
            throw err
            client.describe();
        } else
            console.log(result);
    });
});

return response.render('index', {
    variable: 'valor'
    });
};

我使用以下文档：Github项目

现在我的文件看起来是：

var soap = require('soap');

// url del wsdl
this.getSoap = function (request, response) {
var url = 'http://identificacion.uci.cu/servicios/v5/servicios.php';
var args = { IdExpediente: '016381' };

soap.createClient(url, function (err, client) {
    if (err) {
        console.log(err);
    } else {
        client.ObtenerFotoDadoIdExpediente(args, function (err, result) {
            if (err) {
                throw err
                client.describe();
            } else
                console.log(result);
        });
    }
});

并在我的服务器中获取以下内容：

无法设置null的属性“descriptions”

Answer 1

第一件事首先--当抛出一个错误，指定对象“没有方法”，并且我们期望有一个给定名称的方法，这通常表明对象（或类）没有通过定义或错误的require语句正确定义（不一定是您使用不当）。

查看您提供的文档链接，引起此问题的最初项目是require('node-soap')；语句。虽然该项目在github上被称为“node-soap”，但文档中提供的require语句表明该包的名称为“soap”。

尝试替换：

var soap = require('node-soap');

var soap = require('soap');

让我们知道这是否解决了问题--干杯。

这是一个单独的问题（你的第一个问题已经解决了）：

在文档中，client.descripe()方法用于提供“作为JavaScript对象的服务、端口和方法的描述”。

if (err) {
    throw err
    client.describe();
}
