android - 改造okhttp获取随机eofexception

Question

我在调用 REST WS 的 Android 应用程序上工作。该服务本身工作正常(使用 Postman 测试)但我偶尔会从 Android 收到此异常:

: java.io.IOException: unexpected end of stream on com.squareup.okhttp.Address@2cd22e9d

我在网上找到了一些关于错误的信息，但我不确定。另外，奇怪的是有时可以，有时不能，而无需我更改代码中的任何内容。该异常说明了有关缺少结束行字符的内容。我必须把它放在 URL 中吗？这是一些代码。谢谢。

API接口(interface)

public interface ApiInterface {

@Headers({"Authorization: Bearer eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJkb25hdG8iLCJ1c2VySWQiOiIxIiwicm9sZSI6IlJPTEVfQURNSU4ifQ.yNVtQMfMasfR7nfBgtjtmlXMM8Gpfjvf_FDz1sMiaSJxUvLDyC9sjm-XSEkJdfGy4JasfweRrRUGc3gHpMRA",
            "Accept: application/json",
"Content-Type: application/json;charset=utf-8"})
@POST("/todo/getTodoList")
public void getTodoList(@Body BaseRequest request, Callback<GetTodoListResponse> response);
}

Controller

 RestAdapter restAdapter = new RestAdapter.Builder()
            .setEndpoint("http://www.myUrl.com/app/rest").setLogLevel(RestAdapter.LogLevel.FULL).setConverter(new GsonConverter(builder.create()))
            .setClient(new OkClient(new OkHttpClient()))
            .build();
    ApiInterface methods = restAdapter.create(ApiInterface.class);
    Callback<GetTodoListResponse> callback = new Callback<GetTodoListResponse>() {
        @Override
        public void success(GetTodoListResponse o, Response response) {
            todoList = o.getTodoList();
            Log.d("CardController", "TodoList: " + todoList);
            if (!o.isOutcome()) {
                Log.e("CardController", "Error fetching todoList");
                todoList = new ArrayList<Todo>();
            } else {
                setChanged();
             myMethod();
            }
        }

        @Override
        public void failure(RetrofitError retrofitError) {
            Log.e("Retrofit", "Error fetching todoList: ", retrofitError);
        }
    };
    methods.getTodoList(new AuraBaseRequest(), callback);

Answer 1

在我的例子中，服务器端是 Spring MVC，我收到了这个错误。发生此错误的原因是某些安全检查(500 返回状态)，但改造中的错误是流的意外结束。一旦安全检查被绕过，我就能够得到响应。

希望它能对将来的人有所帮助。
