A light weight and practical OkHttp log interceptor

Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Add the dependency in your module's build.gradle:

dependencies {
    implementation 'com.github.zeropercenthappy:OkHttpLogInterceptor:1.6.7'
}

val logInterceptor = OkHttpLogInterceptor("yourOwnTag")
// add this interceptor
val okHttpClient = OkHttpClient.Builder()
	.addNetworkInterceptor(logInterceptor)
	// or
    // .addInterceptor(logInterceptor)
    .build()

OkHttpLogInterceptor logInterceptor = new OkHttpLogInterceptor("yourOwnTag");
// add this interceptor
OkHttpClient okHttpClient = new OkHttpClient.Builder()
    	.addNetworkInterceptor(logInterceptor)
    	// or
        // .addInterceptor(logInterceptor)
        .build();

It will print as below:

​ If using addInterceptor()method to add this log interceptor to Application Interceptor, the log print will not inclue standard headers of request, because these headers will be added during OkHttp core flow which is beyond Application Interceptor.

​ Alternative, you can use addNetworkInterceptor() method to add this log interceptor to Network Interceptor. In this case you can see every thing is included in the log print. But if cache is enable and the cache of a request is exist, log interceptor will not print anything. Becasuse cache flow and network flow are exclusive.
