在使用"request“模块的node.js中使用POST操作时出现故障

Question

我正在使用node js，jasmine框架来进行API自动化测试。我有个POST手术。我使用npm-request来做这个操作。

我在测试用例中的代码如下

describe('Verification of BS_057_LockDN',()=>{

    it('Verify success response for BS_057_LockDN',function(done){
        var path=require('path');
        let inputJson=require(path.resolve('./inputRequests/lockDNInput.json'));
        let endpoint=require(path.resolve('./config/endpointLockDN.json'));

        const fetch=require('node-fetch');

        let baseUrl=endpoint.url;
        let apikey=endpoint.apikey;

    let fullUrlWithQueryParameters= baseUrl + "?apikey=" + apikey

        console.log(fullUrlWithQueryParameters);
        console.log(inputJson);
        console.log("test");


        var request = require('request');

     request.post(fullUrlWithQueryParameters,inputJson,
    function (error, response, body) {
        console.log('ew fu----------------------------------------------')
        if (error) 
            {

                console.log(error);
                return done();
            }
            console.log('first');
            console.log('HTTP STATUS CODE:'+ response.statusCode);
            console.log('second');
            console.log(body);
            expect(body).not.toBeUndefined();
            expect(body.Header.MsgType_T).toBe('RESPONSE');
            done();
    }
);

    },1000*60*60)


})

当我运行这个测试用例时，我得到以下错误

我不确定为什么我的POST操作没有定义。我使用的方法是正确的吗？

我已经附加了SOAP ui请求和响应。

Answer 1

您的请求似乎是可以的。但是您正在尝试从body中未定义的字段读取数据

expect(body.Header.MsgType_T).toBe('RESPONSE');

这里"Header“不存在于body中。

Answer 2

在没有检查的情况下，永远不要进行两步对象访问。

在这里，您正在访问"expect(body.Header.MsgType_T).toBe('RESPONSE');“中的"body.Header.MsgType_T”，而没有检查"body.Header“是否存在。

希望这能帮上忙..
