网格activity布局(layout_griditem)

用于Ok封装工具类的拦截器(Intercept)

package com.bwie.sc.utils;

import java.io.IOException;

import okhttp3.HttpUrl;
import okhttp3.Interceptor;
import okhttp3.Request;
import okhttp3.Response;

/**

*/

public class Intercept implements Interceptor {
@Override
public Response intercept(Chain chain) throws IOException {
Request original = chain.request();
HttpUrl url=original.url().newBuilder()
.addQueryParameter("source","android")
.build();
//添加请求头
Request request = original.newBuilder()
.url(url)
.build();
return chain.proceed(request);
}
}

Ok封装工具类(OKHttpUtils)

package com.bwie.sc.utils;

import android.os.Handler;
import android.util.Log;

}

/**

Ok封装工具类的接口(IOkHttpUtils)

package com.bwie.sc.utils;

/**

public interface IOkHttpUtils {

void onSuccess(String str);

void onFailed(String message);
