Detailed explanation of Nodejs calling WebService

This article mainly introduces the sample code of Nodejs calling WebService. The editor thinks it is quite good. Now I will share it with you and give it as a reference. Let’s follow the editor to take a look, I hope it can help everyone.

In the past two days, I have been trying to write js for pure static pages to call WebService written in Java, but I have been unable to succeed (the main construction period is tight, I will study it later when I have more free time, and see if I can You cannot write a pure static page js to call WebService). In the end, there is no other way but to change to Node JS to call WebService. I wanted to find some information on the Internet, but found that nothing was satisfactory. In the end, I could only refer to the documents on the official website and made a client-side program based on my own needs. I hope it will be helpful to everyone.

First do the preliminary preparations. Assume that you have installed nodejs, because I did not set it through the project, but directly through the command, so Let's first install the nodejs package that needs to be used (if you use the project method, you can configure package.json to achieve it)

The command is as follows

npm install soap 
npm install sinon 
npm install request 
npm install debug 
npm install lodash 
npm install soap 
npm install concat-stream 
npm install optional 
npm install ejs 
npm install xml-crypto 
npm install node-uuid 
npm install sax 
npm install strip-bom 
npm install selectn 
npm install mocha –save-dev

Installation After finishing this part, you can start writing code. File name myServer.js.

The code is as follows

var wsdlOptions ={
  "overrdeRootElement":{
    "namespace":"xmlns:tns",
    "xmlnsAttributes":[{
        "name":"xmlns:ns",
        "value":"http://www.php.cn/"
    }]
  }
};

var url='http://www.php.cn/WebService/WebService?wsdl';

var soap=require('soap');

var args={'Param1':'value1','Param2':'value2'};
soap.createClient(url,wsdlOptions,function(err,client){
if(err!==null){
console.log(err);
}
// client.setSOAPAction(url);
client.MyService(args,function(err,result){
if(err!==null){
console.log(err);
}
console.log
(result);
});

});

Test through the command

##

node myServer.js

, and the result will be based on The data returned by the server, what I get here is a JSON data. (According to the data returned by the server, what I get here is a JSON data.

Note: http://www.php.cn Replace it with the namespace of your own service, var url='http://www.php.cn/WebService/WebService?wsdl'; replace it with your own service address. It is best not to use new Array() to create the args parameter. Using JSON data, the number of parameters needs to be set more realistically. Finally, if you want to run it on a browser, you need to solve the security problem before it can be used normally.
