HTTP request POST with x-www-form-urlencoded in Agular 6

I need to make an HTTP POST request with x-www-form-urelcoded in angle 6.

I tried something like:

  pesquisaEmail(email): Observable<any>{
    let headers = new HttpHeaders();
    headers.append('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
    headers.append('Content-Type', 'application/x-www-form-urlencoded');

    this.token = localStorage.getItem('currentUser');

    return this._http.post<any>(AppSettings.API_ENDPOINT_EMAIL,
      {email: email,
      token_jc: this.token},
      { headers: headers, observe: 'response' })
        .pipe(
          map((response) => ({data: response.body, status: response.status}))
      )}

}

@Edit I've also tried:

pesquisaEmail(email): Observable<any>{
    let headers = new HttpHeaders();
    headers.append('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
    headers.append('Content-Type', 'application/x-www-form-urlencoded');

    this.token = localStorage.getItem('currentUser');
    let body = new URLSearchParams();
    body.set('email', this.token);
    body.set('token_jc', email);

    return this._http.post<any>(AppSettings.API_ENDPOINT_EMAIL,
      body,
      { headers: headers, observe: 'response' })
        .pipe(
          map((response) => ({data: response.body, status: response.status}))
      )}

}

but unsuccessful

I get a bad request error. Does anyone know how I can make this type of request?
