okhttp string problem if using string in .url

Question

I'm using API from a website and it needs two strings String one: modelId String two: inferenceId both of them are equal to value

OkHttpClient client = new OkHttpClient();

                Request request = new Request.Builder()
                        .url("https://api.leapml.dev/api/v1/images/models/"+modelId+"/inferences/"+inferenceId)
                        .get()
                        .addHeader("accept", "application/json")
                        .addHeader("authorization", "Bearer *secret word here*")
                        .build();
                
                Response response = client.newCall(request).execute();

My issue is in Example: A

.uri("https://api.leapml.dev/api/v1/images/models/"+modelId+"/inferences/"+inferenceId)

if I added both modelId string and inferenceId string the the above code, the API doesn't work correctly

but if I add the text directly there like in below, everything works great Example: B

.url("https://api.leapml.dev/api/v1/images/models/1285ded4-b11b-4993-a491-d87cdfe6310c/inferences/3f9f5c8d-320f-4afc-85c4-454522118c16")

Both of the above gives me the EXACT same result if I got the value of request.url(); but the API gets faulty with the example A But works fine with example B

Log of Example A (faulty one)

I/System.out: Second Step: {"id":"f9828985-af41-46be-b8bc-ef81504b4a87","state":"queued","prompt":"cow","seed":4523184,"width":1024,"height":1024,"numberOfImages":1,"steps":50,"weightsId":"8b1b897c-d66d-45a6-b8d7-8e32421d02cf","workspaceId":"d76af992-7c3e-4b1a-bc72-46b27de7c377","createdAt":"2023-02-01T09:56:42.255006+00:00","images":[],"modelId":"8b1b897c-d66d-45a6-b8d7-8e32421d02cf"}

Log with Example B (Working perfect)

I/System.out: Second Step: {"id":"3f9f5c8d-320f-4afc-85c4-454522118c16","state":"finished","prompt":"cow","seed":4523184,"width":512,"height":512,"numberOfImages":1,"steps":50,"weightsId":"1285ded4-b11b-4993-a491-d87cdfe6310c","workspaceId":"d76af992-7c3e-4b1a-bc72-46b27de7c377","createdAt":"2023-02-01T08:54:31.244159+00:00","images":[{"id":"f6518aea-f2a3-47ac-b9ff-81ca8c996206","uri":"https://dreamtrain.s3.us-west-2.amazonaws.com/image-gen-3f9f5c8d-320f-4afc-85c4-454522118c16/generated_images/0.png","createdAt":"2023-02-01 08:54:42.784652+00"}],"modelId":"1285ded4-b11b-4993-a491-d87cdfe6310c"}

As you can see Example B has "uri" image link and that's what i need.

I tried many things but it seemed like nothing help.

Answer 1

String url = "https://api.leapml.dev/api/v1/images/models/"+modelId+"/inferences/"+inferenceId;

System.out.println(url); // This should be equal to "https://api.leapml.dev/api/v1/images/models/1285ded4-b11b-4993-a491-d87cdfe6310c/inferences/3f9f5c8d-320f-4afc-85c4-454522118c16"

// Use the variable as argument
.url(url);

If this still not work. Please provide the logs.

Answer 2

It seems your are trying to add binary data to the string. Check whether your are getting the actual string which you need.

Answer 3

I found the issue and the solution, The API I'm using (Leapml) takes about 10 seconds to generate me the image link. So if I let the thread sleep for 11 seconds everything works just great

Thanks for everyone tried to help.
