如何使用数据库、用户名、密码从数据库网络获取 api

Question

I'm setting up My connection with SAP Service layer one. I have used static API but this time want to connect to API using

[
    username: { UserName: 'MySAPUserName', DBCompany: MySAPDBName }, 
    Password: "MySAPPassword"
]

I don't know how to setup connection in react native using this basic authentication.

I trie some of the solution but failed to get the response

var headers = new Headers();
    headers.append("Authorization", "Basic " + base64.encode('{UserName:'MySAPUserName',DBCompany:MySAPDBName}:MySAPPassword'));
    fetch("https://EEPLhana:50000/b1s/v1/ProjectsService_GetProjectList",{
        headers: headers
    }) 
    .then((response) => response.json())
    .then((responseJson) => {
        console.log(responseJson);
    })
    .catch((error) =>{
        console.error(error);
    });

I am not sure if you have these variables in scope, since you have only shared a snippet. But assuming these are variables, the string concatenation is wrong. and the structure also seems wrong

headers.append("Authorization", "Basic " + base64.encode('{"UserName":"'+MySAPUserName+'","DBCompany":"'+MySAPDBName+'", "Password":"'+MySAPPassword+'"}'));

A better approach would be to create an object and stringify it like below

let auth = { Username: MySAPUserName, DBCompany: MySAPDBName, Password: MYSAPPassword };
headers.append("Authorization", "Basic " + base64.encode(JSON.stringify(auth)));
