背景
开发中,有时需要核对接口请求和响应参数,需要看到详细的接口调用。本来可以通过Facebook Stetho来监控接口的,但是受限于网络,导致调测界面打不开,所以只要寻求其他方案。
解决方案
通过okhttp添加拦截器,打印接口调用日志。
添加依赖
implementation 'com.squareup.okhttp3:logging-interceptor:3.9.1'添加拦截器
HttpLogInterceptor.java
import android.util.Log;import java.io.IOException;import java.nio.charset.Charset;import java.nio.charset.UnsupportedCharsetException;import java.util.concurrent.TimeUnit;import okhttp3.Interceptor;import okhttp3.MediaType;import okhttp3.Request;import okhttp3.RequestBody;import okhttp3.Response;import okhttp3.ResponseBody;import okio.Buffer;import okio.BufferedSource;/**
* okhttp 拦截器
*/public class HttpLogInterceptor implements Interceptor { private static final String TAG = HttpLogInterceptor.class.getSimpleName(); private final Charset UTF8 = Charset.forName("UTF-8"); @Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request();
RequestBody requestBody = request.body();
String body = 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);
}
body = buffer.readString(charset);
}
Log.d(TAG, "发送请求: method:" + request.method()
+ "\nurl:" + request.url()
+ "\n请求头:" + request.headers()
+ "\n请求参数: " + body); long startNs = System.nanoTime();
Response response = chain.proceed(request); long tookMs = TimeUnit.NANOSECONDS.toMillis(System.nanoTime() - startNs);
ResponseBody responseBody = response.body();
String rBody;
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();
}
}
rBody = buffer.clone().readString(charset);
Log.d(TAG, "收到响应: code:" + response.code()
+ "\n请求url:" + response.request().url()
+ "\n请求body:" + body
+ "\nResponse: " + rBody); return response;
}
}添加拦截器(该拦截器需要最后添加,否则其他对request、response做修改的Interceptor所导致的变更就无法打印出来的。):
Interceptor loggingInterceptor = new HttpLoggingInterceptor(); okBuilder.addInterceptor(loggingInterceptor)
打印出的日志样例:
