Problem analysis of nodejs implementation of webservice

The content of this article is about the analysis of the problem of nodejs implementing webservice. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

Library, tool

node-soap
soapui

Create

Note the order of parameters in args

const soap = require('soap');
let URL = "你的wsdl路径，可以是url或者本地文件";
// 注意参数顺序！！！！！！！！！
let args = {
    key1: val1,
    key2: val2
};
// promise创建
let client = await soap.createClientAsync(URL);

// callback创建
soap.createClient(url, function(err, client) {
    client.MyFunction(args, function(err, result) {
          console.log(result);
    });
});

I personally like the promise form. Calling other functions can be implemented in two ways. If it is asynchronous, you need to add "Async" after the function name you call.

Call

There is nothing special about having only one layer of parameter data, such as:

args = {
    key1: val1,
    key2: val2
}

If there is another layer in the parameter, node-soap will not automatically generate the band based on wsdl Data with namespace prefix will fail to parse XML after being transmitted to the server.

For example:

let val2: Array<datatype> = [
        {
            key3: val3
        }
    ];
let args = {
    key1: val1,
    key2: val2
}</datatype>

At this time, you need to do some extra work when passing in the data. Change it to:

let val2: Array<datatype> = [
        {
            key3: val3
        }
    ];
let args = {
    key1: val1,
    key2: {
        dataType: val2
    }
}</datatype>

The above dataType is the type when generating xml. There is a declaration in xml; if there is no declaration, it is written in another way, such as:

// dataType或namespace prefix在生成xml未声明
let val2: Array<datatype> = [
        {
            key3: val3
        }
    ];
let args = {
    key1: val1,
    key2: val2
}</datatype>

needs to be rewritten as (Array is used here to refer to the namespace prefix generated by soapui, and other types are specified. The implementation should be universal);

let val2: Array<string> = [
        val3,
        val4
    ];
let args = {
    attributes: {
       'xmlns:arr': 'http://schemas.microsoft.com/2003/10/Serialization/Arrays'
    },
    key1: val1,
    key2: {
        "arr:string": val2
    }
}</string>

Pay attention to the order of parameters in args

const soap = require('soap');
let URL = "你的wsdl路径，可以是url或者本地文件";
// 注意参数顺序！！！！！！！！！
let args = {
    key1: val1,
    key2: val2
};
// promise创建
let client = await soap.createClientAsync(URL);

// callback创建
soap.createClient(url, function(err, client) {
    client.MyFunction(args, function(err, result) {
          console.log(result);
    });
});
