Hello, i receive this error:
{{
“error”: “Authorization field/api_key missing in request. If you do not have a token, please sign up for one at https://openrouteservice.org”
}}
Api key is correct because i paste link generated from instruction i obtain correct response from browser as you can see:
what am I doing wrong?
Hi @Fabio7586,
your API key is still visible in the second URL.
You can try adding a Content-Type Header similar to the Accept header with
"Content-Type: application/json; charset=utf-8".
That might be the problem, but not quite sure as i’m not familiar with C#.
If you can get the request to work, would be great if you let us know how, so we can update the C# example of the Playground.
Best regards
No way, seems related to Authenticate so i decided to change apporoach: I followed example about posting json:
Quotas are ok; I checked result JSON format with online tool.
Someone can help me?
Thank you
Hmm that’s rather strange…
Maybe you have to set it directly in the request, else it might be derived from the content, which is a string…
try this:
As you suggested, i followed example:
result is:
[0:] Response: StatusCode: 405, ReasonPhrase: ‘Not Allowed’, Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{

}
Any ideas?
Found a solution for GET:
var url = "https://api.openrouteservice.org/v2/directions/driving-car?api_key=your_api_key&start=8.681495,49.41461&end=8.687872,49.420318";
var httpRequest = (HttpWebRequest)WebRequest.Create(url);
httpRequest.Headers["Authorization"] = "Bearer your_api_key";
var httpResponse = (HttpWebResponse)httpRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}
Console.WriteLine(httpResponse.StatusCode);
I’m trying to test POST method with an online working tool. No way to work it give same error given by my app:
For the get request both api_key parameter and Authorization header can be used.
However, in the Header you don’t need Bearer, just Authorization: 5b3ce3.....
In your online tool, you don’t have th right path to the directions endpoint. It should be something like:
https://api.openrouteservice.org/v2/directions/driving-car
Please check the documentation for available ones.
You can try generating a curl request with the example code button, to see which the minimal Headers are that you nead for the request.
Ok, you are right: in the GET it doesn’t need Bearer; it work without it.
For the POST following code works very well:
var url = "https://api.openrouteservice.org/v2/directions/driving-car/json";
var httpRequest = (HttpWebRequest)WebRequest.Create(url);
httpRequest.Method = "POST";
httpRequest.Accept = "application/json";
httpRequest.Headers["Authorization"] = "Bearer 5b3ce3597851110001cf6xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
httpRequest.ContentType = "application/json";
var data = @"{""coordinates"":[[8.681495,49.41461],[8.686507,49.41943],[8.687872,49.420318]]}";
using (var streamWriter = new StreamWriter(httpRequest.GetRequestStream()))
{
streamWriter.Write(data);
}
var httpResponse = (HttpWebResponse)httpRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}
Console.WriteLine(httpResponse.StatusCode);
but,
your example in the API Playground dont work (ok, in the online tool with correct uri, works) check screen with result error:
AH, I FORGOT to say that, i’m using Xamarin Forms that support only mono framework (yes in short will be support fully .net 6 and c#9) taht is similar to .net standard 2.
Here you go
using System;
using System.Text;
using System.Net.Http;
using System.Net.Http.Headers;
using Newtonsoft.Json;
var baseAddress = new Uri("https://api.openrouteservice.org");
using (var httpClient = new HttpClient{ BaseAddress = baseAddress })
{
httpClient.DefaultRequestHeaders.Clear();
httpClient.DefaultRequestHeaders.TryAddWithoutValidation("accept", "application/json, application/geo+json, application/gpx+xml, img/png; charset=utf-8");
httpClient.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue("Bearer", "xxx");
// quotes might have to be escaped
using (var content = new StringContent("{\"coordinates\":[[8.681495,49.41461],[8.686507,49.41943],[8.687872,49.420318]]}", Encoding.UTF8, "application/json"))
{
using (var response = await httpClient.PostAsync("/v2/directions/driving-car", content))
{
string responseData = await response.Content.ReadAsStringAsync();
var data = JsonConvert.DeserializeObject(responseData);
var serialised = JsonConvert.SerializeObject(data);
Console.WriteLine(serialised);
}
}
}
OMG It works. I’m sure that i have tested your solution and it gave me:
{
“error”: “Daily quota reached or API key unauthorized”
}
maybe i was worng in something…
Thank you for fully support you gave me!!!
