404使用翻新发出POST请求时

Question

I have the following API call I created using Retrofit2:

@Headers({"Accept: application/json", "Content-Type: application/json"})
@POST("task/create/")
Call<StandardTaskResponse> createNewTask(@Body Task newTask);

and I try to use that method like so:

Task newTask = new Task(name, description, "", null, USER, 4, priority, null, null);

      Call<StandardTaskResponse> call = HavocService.getInstance().getHavocAPI().createNewTask(newTask);
        call.enqueue(new Callback<StandardTaskResponse>() {
            @Override
            public void onResponse(Call<StandardTaskResponse> call, Response<StandardTaskResponse> response) {
                LogUtil.v("Response message: " + response.message());
            }

            @Override
            public void onFailure(Call<StandardTaskResponse> call, Throwable t) {
                LogUtil.e(t.getCause().getMessage());
            }
        });

This is what the logs show:

I have searched around on other StackOverflow answers and the common suspect is the base URL. Mine is accessed like so:

private static final String HAVOC_URI = "http://ec2-amazonaws-base-url-redacted.com:3000/api/"; .

The body for this API call is just supposed to be the Task I want to create. The response is supposed to be something of the form:

{
    "status":true,
    "doc":{
        "_id":"5801175bc5c3f451301fd235",
        "t_id":"8671fc295bc9",
        "name":"Do calculus homework",
        "description":"Finish all assigned homework from chapters 1 and 2",
        "category":"test",
        "indexInList":0,
        "priority":3,
        "dateDue":1477291500000,
        "user":"57a",
        "status":"ARCHIVED",
        "__v":0,
        "subtasks":[
            {
                "name":"Finish Chapter 1 - Derivatives",
                "isCompleted":false
            },
            {
                "name":"Finish Chapter 1 - Integrals",
                "isCompleted":false
            },
            {
                "name":"Finish Chapter 2 - Graphing",
                "isCompleted":false
            }
        ]
    }
}

Which is: status : whether or not there was an error on the backend, doc: task that was just created

I have no clue why this is happening. I'm certain the base URL is correct. I can actually use a REST API test app from the Play Store and do a POST request with an empty body and the response is correct. It's only when I attempt this on Android do I get this error.

I'd appreciate any and all help.

Answer 1

Turns out I'm an idiot. I needed to remove the ending backslash for the @POST parameter.

@Headers({"Accept: application/json", "Content-Type: application/json"})
@POST("task/create")
Call<StandardTaskResponse> createNewTask(@Body Task newTask);
