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();
But I only see this in the logs:
request:
com.squareup.okhttp.RequestBody$1@3ff4074d
headers:
Content-Type: application/vnd.ll.event.list+json
How am I supposed to do proper logging, given the removal of setLog()
and setLogLevel()
which we used to use with Retrofit 1?
In Retrofit 2 you should use HttpLoggingInterceptor.
Add dependency to build.gradle
. Latest version as of October 2019 is:
implementation 'com.squareup.okhttp3:logging-interceptor:4.2.1'
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);
In case of deprecation warnings, simply change setLevel
to:
interceptor.level(HttpLoggingInterceptor.Level.BODY);
The above solution gives you logcat messages very similar to the old ones set by
setLogLevel(RestAdapter.LogLevel.FULL)
In case of java.lang.ClassNotFoundException
:
Older Retrofit version might require an older logging-interceptor
version. Take a look at comments sections for details.
