Today I had some problems with designing a Retrofit<\/a> REST application, so I needed a way to debug the request and the response from the server. After poking around, I found the HttpLoggingInterceptor<\/em> from OkHttp<\/a>.\u00a0 It provides all the functionality I need and is really easy to implement.<\/p>\n

First you have create a OkHttpClient<\/em> instance, add the interceptor and set the debug level to HttpLoggingInterceptor.Level.BODY:<\/em><\/p>\n

OkHttpClient client = new OkHttpClient();\r\nHttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();\r\ninterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);\r\nclient.interceptors().add(interceptor);\u00a0\u00a0\u00a0 \r\n<\/code><\/pre>\n
Next step is to add the client during the building of the Retrofit instance:<\/p>\n
Retrofit retrofit = new Retrofit.Builder().client(client).build();<\/code><\/pre>\n
Now you can see the HTTP data sent over the wire:<\/p>\n

Don’t forget to add the two required dependencies to your pom.xml<\/em>:<\/p>\n
<dependency>\r\n   <groupId>com.squareup.okhttp<\/groupId>\r\n   <artifactId>okhttp<\/artifactId>\r\n   <version>2.6.0<\/version>\r\n<\/dependency>\r\n<dependency>\r\n   <groupId>com.squareup.okhttp<\/groupId>\r\n   <artifactId>logging-interceptor<\/artifactId>\r\n   <version>2.6.0<\/version>\r\n<\/dependency><\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
