cannot authenticate with API 400 bad request

I'm trying to authenticate the user with API. I have implemented a method for login function

login()

this.key = this.credentials.username + ":" + this.credentials.password;
this.base64 = btoa(this.key) //base64

this.url = encodeURI(this.base64); //url

this.contentHeader = new HttpHeaders().set("Authorization", "Basic " + this.url);

return new Promise((resolve, reject) =>
console.log(this.contentHeader)
this.http.post(this.LOGIN_URL, null, headers: this.contentHeader )
.subscribe(res =>
resolve(res);
console.log("success:" + res)
res => this.authSuccess(res.id_token)

, (err) =>

console.log("rejected");
reject(err);
);
);


I'm trying to concatenate username and password and then encoded to base64. again it encoded to URL and post with combining with the header. I'm getting authenticated properly with the postman correctly. but in the ionic app, it says bad request.

When you send a POST request using HTTP or HTTPClient, the second parameter is sent as the POST body. It seems in your code you're sending the Authorization not as a header, but as the POST body.

Change it to:

this.http.post(this.LOGIN_URL, null,
headers: HttpHeaders().set("Authorization", "Basic " + this.url)
)
