Created a MTAR application in VS Code with app router . made the changes in start file of approuter to a different file let say custominfo.js as below
below is the code in custominfo.js
const approuter = require("@sap/approuter");
const jwtDecode = require("jwt-decode");
const rp = require("request-promise");
const xsenv = require("@sap/xsenv");
xsenv.loadEnv();
const dest_service = xsenv.getServices({ dest: { tag: "destination" } }).dest;
const uaa_service = xsenv.getServices({ uaa: { tag: "xsuaa" } }).uaa;
const sUaaCredentials = dest_service.clientid + ":" + dest_service.clientsecret;
const sDestinationName = "devapi";
let ar = approuter();
ar.beforeRequestHandler.use("/data", (req, res) => {
let email = jwtDecode(req.user.token.accessToken).email;
return rp({
uri: uaa_service.url + "/oauth/token",
method: "POST",
headers: {
"Authorization": "Basic " + Buffer.from(sUaaCredentials).toString("base64"),
"Content-type": "application/x-www-form-urlencoded"
},
form: {
"client_id": dest_service.clientid,
"grant_type": "client_credentials"
}
}).then((data) => {
const token = JSON.parse(data).access_token;
return rp({
uri: dest_service.uri + "/destination-configuration/v1/destinations/" + sDestinationName,
headers: {
"Authorization": "Bearer " + token
}
});
}).then((data) => {
const oDestination = JSON.parse(data);
const url = oDestination.destinationConfiguration.URL;
// need to send email address and app router url to fetch some json data in the API c
configured in destination
}).then((result) => {
}).catch((error) => {
});
});
ar.start();
In the above node js script i need to send email address and app router URL to other REST api to fetch some data .
so question was
How would i get email address from JWT Token in first Request Promise(rp) and destination URL from destination service in second Request Promise(rp) and pass these thing to third Request promise (rp) .
Third Request promise should trigger a REST API (Url is extracted from the destination service in second RP ) and should send the email address and the app router url in the header part to that REST API returns custom JSON .
i was able to get url and email in separate Request promise but couldn't get the app router URL.
