For a Dutch employment agency I'm trying to write a bit of code that will use the Google index API to update googles information when a new job is posted or removed. For starters I try to get the notification status, but the response is 404 despite the website obviously being available.
As a starting programmer my conclusion is that I likely made an error within the code somewhere, or that the task at hand is simply impossible since the API is not officially available in my country (The Netherlands)
I unfortunately don't have any ownership of similar sites located in supported countries to assure my code is the problem here.
Searching for topics on this error returns a massive amount of information, none of it so far seems to address my issue sadly enough.
The error appears at the line using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
Below is my code:
using Google.Apis.Auth.OAuth2;
using System.IO;
using System.Threading.Tasks;
class AccessTokenGenerate
{
public static async Task<string> GetAccessTokenFromJSONKeyAsync(string jsonKeyFilePath, params string[] scopes)
{
using (var stream = new FileStream(jsonKeyFilePath, FileMode.Open, FileAccess.Read))
{
return await GoogleCredential
.FromStream(stream) // Loads key file
.CreateScoped(scopes) // Gathers scopes requested
.UnderlyingCredential // Gets the credentials
.GetAccessTokenForRequestAsync(); // Gets the Access Token
}
}
public static string GetAccessTokenFromJSONKey(string jsonKeyFilePath, params string[] scopes)
{
return GetAccessTokenFromJSONKeyAsync(jsonKeyFilePath, scopes).Result;
}
public static async Task<string> GetTokenAndCall()
{
var keyFilePath = @"E:\LocationOnDisk\KeyFilename.json";
var scopes = new[] { "https://www.googleapis.com/auth/indexing" };
GoogleCredential credential;
using (var stream = new FileStream(keyFilePath, FileMode.Open, FileAccess.Read))
{
credential = GoogleCredential.FromStream(stream)
.CreateScoped(scopes);
}
var token = await credential.UnderlyingCredential.GetAccessTokenForRequestAsync();
return token;
}
public static string GetToken()
{
var task = GetTokenAndCall();
task.Wait();
var result = task.Result;
return result;
}
}
using System;
using System.IO;
using System.Net;
class Program
{
static void Main(string[] args)
{
var token = AccessTokenGenerate.GetToken();
string responseString = "";
string uri = "https://indexing.googleapis.com/v3/urlNotifications/metadata?url=https%3A%2F%2Fwww.WEBSITEHERE.nl%2F";
WebRequest request = WebRequest.Create(uri);
request.PreAuthenticate = true;
request.ContentType = "application/json";
request.Headers.Add("Authorization", "Bearer " + token);
request.Method = "GET";
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
using (Stream stream = response.GetResponseStream())
using (StreamReader reader = new StreamReader(stream))
{
responseString = reader.ReadToEnd();
}
Console.WriteLine(responseString);
Console.ReadKey();
}
}
