Question

我使用Retrofit2创建了以下API调用：

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());
            }
        });

我试着像这样使用那个方法：

这是日志显示的内容：

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

我搜索过其他StackOverflow答案，常见的嫌疑人是基本网址。我的访问方式如下：

Task。

此API调用的主体应该是我想要创建的{ "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 } ] } }。响应应该是以下形式：

status

哪个是：doc:：后端是否有错误，AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimsIdentity.DefaultNameClaimType;刚刚创建的任务

我不知道为什么会这样。我确定基本URL是正确的。我实际上可以使用REST API test app from the Play Store并使用空主体执行POST请求，并且响应是正确的。只有当我在Android上尝试这个时才会出现此错误。

我会感激任何帮助。

Answer 1

原来我是个白痴。我需要删除@POST参数的结尾反斜杠。

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

404使用Retrofit发出POST请求时
