使用Retrofit 2进行记录 [英] Logging with Retrofit 2

问题描述

我正在尝试获取请求中发送的确切JSON。这是我的代码：

I'm trying to get the exact JSON that is being sent in the request. Here is my code:

OkHttpClient client = new OkHttpClient();
client.interceptors().add(new Interceptor(){
   @Override public com.squareup.okhttp.Response intercept(Chain chain) throws IOException {
      Request request = chain.request();
      Log.e(String.format("\nrequest:\n%s\nheaders:\n%s",
                          request.body().toString(), request.headers()));
      com.squareup.okhttp.Response response = chain.proceed(request);
      return response;
   }
});
Retrofit retrofit = new Retrofit.Builder()
   .baseUrl(API_URL)
   .addConverterFactory(GsonConverterFactory.create())
   .client(client).build();

但我只在日志中看到这一点：

But I only see this in the logs:

request:
com.squareup.okhttp.RequestBody$1@3ff4074d
headers:
Content-Type: application/vnd.ll.event.list+json

如果删除 setLog（）和 setLogLevel（）我们曾经使用过Retrofit 1？

How am I supposed to do proper logging, given the removal of setLog() and setLogLevel() which we used to use with Retrofit 1?

推荐答案

在Retrofit 2中你应该使用 HttpLoggingInterceptor 。

In Retrofit 2 you should use HttpLoggingInterceptor.

将依赖项添加到 build.gradle ：

compile 'com.squareup.okhttp3:logging-interceptor:3.9.1'

创建一个 Retrofit 对象，如下所示：

Create a Retrofit object like the following:

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://backend.example.com")
        .client(client)
        .addConverterFactory(GsonConverterFactory.create())
        .build();

return retrofit.create(ApiClient.class);

以上解决方案为您提供与

The above solution gives you logcat messages very similar to the old ones set by

setLogLevel(RestAdapter.LogLevel.FULL)

如果 java.lang.ClassNotFoundException ：

In case of java.lang.ClassNotFoundException:

旧版改造版可能需要较旧的 logging-interceptor 版本。有关详细信息，请查看注释部分。

Older Retrofit version might require an older logging-interceptor version. Take a look at comments sections for details.
