在POST请求中，拦截器卡在它的创建上

标签： android web-services http-post retrofit2 interceptor

我有一个应用程序需要为我的服务器发送一个POST请求，通过JSON发送一个项目列表。但要执行此POST，它需要带有令牌身份验证的标头配置。当我从应用程序发送请求时，在logcat上，可能会看到拦截器实例化被卡住了。 请看一下我的代码和logcat调试：

public static Retrofit getServerClient(String token) {
    Log.d("DEBUG 1 -> ","getServerClient");
    OkHttpClient httpClient;
    Gson gson = new GsonBuilder()
            .setDateFormat("yyyy-MM-dd'T'HH:mm:ss")
            .create();
    Retrofit.Builder builder = new Retrofit.Builder()
            .baseUrl(SERVER_BASE_URL)
            .addConverterFactory(GsonConverterFactory.create(gson));
    if (token!=null && !TextUtils.isEmpty(token)) {
        Log.d("DEBUG 2 -> ","getServerClient needs add header");
        httpClient = getHttpClientWithInterceptor(token);
        Log.d("DEBUG 8 -> ","getServerClient with headers");
    }else {
        httpClient = getOkHttpClient();
    }
    builder.client(httpClient);
    Log.d("DEBUG 9 -> ","Return server client");
    return builder.build();
}

private static OkHttpClient getHttpClientWithInterceptor(final String token) {
    Log.d("DEBUG 3 -> ","Instantiate interceptor");
    Interceptor interceptor = new Interceptor() {
        @Override
        public Response intercept(Chain chain) {
            try {
                Log.d("DEBUG 4 -> ","Add headers START");
                final Request request = chain.request().newBuilder()
                        .addHeader("Authorization", "Bearer "+token)
                        .addHeader("Content-Type", "application/json")
                        .build();
                Log.d("DEBUG 5 -> ","Add headers END");
                return chain.proceed(request);
            }catch (Exception e){
                Log.d("DEBUG 6 -> ","Failure on request build");
                e.printStackTrace();
                return null;
            }
        }
    };

    OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
    httpClient.addNetworkInterceptor(interceptor);
    Log.d("DEBUG 7 -> ","Return client with interceptor");
    return httpClient.build();
}

GET请求中有什么奇怪的，它可以看到：

    10-30 09:40:16.081 8379-8379/br.com.vegait.android.hotelexperience D/DEBUG 1 ->: getServerClient

但是在POST上它会在循环中显示以下日志：

并保持这样直到崩溃。我做错了什么？

又是我了。

只是留下关于我的问题的反馈。我发现了问题。

我根据请求发送的对象与映射为发送的对象不同。 Idk为什么它会卡住de interceptor，但是当我改变它的对象时，它就像一个魅力。我会把这个留给其他可能有同样问题的人。

谢谢你。

首先，您必须添加崩溃日志。但无论如何，你提供的日志意味着你正在使用内存，然后它被GC释放但似乎你做了很多工作，GC无法提供你需要的内存和你的应用程序用OutOfMemory异常击落。所以首先在这种情况下你必须使用Singleton模式来避免创建所有这些对象（如HttpClient，Gson，Interceptor等）。所以让我们假装这个名为HttpClient的类。那么你需要像NetManager这样的单身人士...... 

public class NetManager {

    private static NetManager instance;
    private HttpClient httpClient;

    private NetManager() {
        httpClient = new HttpClient();
    }

    public static NetManager() {
        if (instance == null) {
            instance = new NetManager();
        }
        return instance;
    }

    public HttpClient getHttpClient() {
        return httpClient;
    }
}

通过此经理使用您的httpClient。

但总的来说，在循环中发出网络请求是非常非常糟糕的。
