android retrofit通过okhttp设置interceptor拦截器统一打印请求报文及返回报文

public class  implements Interceptor {

    private static final String TAG = LogInterceptor.class.getSimpleName();

    
    public Response intercept(Chain chain) throws IOException {
        Charset UTF8 = Charset.forName("UTF-8");

        
        Request request = chain.request();
        RequestBody requestBody = request.body();
        String reqBody = null;
        if(requestBody != null) {
            Buffer buffer = new Buffer();
            requestBody.writeTo(buffer);

            Charset charset = UTF8;
            MediaType contentType = requestBody.contentType();
            if (contentType != null) {
                charset = contentType.charset(UTF8);
            }
            reqBody = buffer.readString(charset);
        }
        Log.d(TAG, String.format("发送请求nmethod：%snurl：%snheaders: %snbody：%s",
                request.method(), request.url(), request.headers(), reqBody));

        // 打印返回报文
        // 先执行请求，才能够获取报文
        Response response = chain.proceed(request);
        ResponseBody responseBody = response.body();
        String respBody = null;
        if(responseBody != null) {
            BufferedSource source = responseBody.source();
            source.request(Long.MAX_VALUE);
            Buffer buffer = source.buffer();

            Charset charset = UTF8;
            MediaType contentType = responseBody.contentType();
            if (contentType != null) {
                try {
                    charset = contentType.charset(UTF8);
                } catch (UnsupportedCharsetException e) {
                    e.printStackTrace();
                }
            }
            respBody = buffer.clone().readString(charset);
        }
        Log.d(TAG, String.format("收到响应n%s %sn请求url：%sn请求body：%sn响应body：%s",
                response.code(), response.message(), response.request().url(), reqBody, respBody));
        return response;
    }
}
