Problem in the Java API Matrix example on the documentation

openrouteservice
1

Hello,

I´m trying to run this matrix example provided on the documentation in Java (here):

Client client = ClientBuilder.newClient();
Entity<String> payload = Entity.json({"locations":[[9.70093,48.477473],[9.207916,49.153868],[37.573242,55.801281],[115.663757,38.106467]]});
Response response = client.target("https://api.openrouteservice.org/v2/matrix/driving-car")
  .request()
  .header("Authorization", "api_key")
  .header("Accept", "application/json, application/geo+json, application/gpx+xml, img/png; charset=utf-8")
  .header("Content-Type", "application/json; charset=utf-8")
  .post(payload);

System.out.println("status: " + response.getStatus());
System.out.println("headers: " + response.getHeaders());
System.out.println("body:" + response.readEntity(String.class));

However I’m getting an error on this line: Entity<String> payload = Entity.json({"locations":[[9.70093,48.477473],[9.207916,49.153868],[37.573242,55.801281],[115.663757,38.106467]]});

The error is this one:
Multiple markers at this line
- Syntax error, insert “;” to complete
LocalVariableDeclarationStatement
- The method json(T) in the type Entity is not applicable for the
arguments ()
- Syntax error on tokens, delete these tokens
- Syntax error, insert “)” to complete MethodInvocation

Since this is a straight up copy from the documentation and I’m relatively new to this matter, does anyone know how to solve it ?

Thanks

Please use proper (code) formatting, i.e. 3 backticks, it really hurts my brain to look at it otherwise.

The code on our documentation is auto-generated, we don’t write any of it. Maybe some of the backend folks will point out the mistake and we can override the code piece.

Hi,

without checking properly, just an idea:
The example is a <String> type Entity. But what is passed is a String followed by an array of floats/doubles. I think you need to either change the type or make the whole statement a String.

Hi @Pedro_Pereira,

First of all, please don’t ever expose your api_key or other people might use it!

I just tested this out shortly and @HendrikLeuschner is right.

You need to pass:

        Entity<String> payload = Entity.json(
                "{\"locations\":[[9.70093,48.477473],[9.207916,49.153868],[37.573242,55.801281],[115.663757,38.106467]]}"
        );

and everything will work without a problem.

Please read 403 Forbidden - Daily quota reached or API key unauthorized
for further info on the escape strings.

Best regards
