本文介绍了如何实现一个自定义的HTTP拦截器，用于在请求中添加额外的参数，并展示了在Android中使用Glide库加载图片的基础操作。拦截器代码示例展示了如何构建请求并添加请求头。

//自定义拦截器
public class Logger 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);
}
}

//1:创建OkHttpClient对象
OkHttpClient okHttpClient = new OkHttpClient.Builder()
        .addInterceptor(new Logger())
        .build();

//将题里的文件给复制进去

OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(new LoggingInterceptor())
        .build();

//图片拆分

String[] split = list.get(position).getImages().split("\\|");
Glide.with(context).load(split[0]).into(holder.listimg);
//1倒依赖
Glide.with(context).load(list.get(position).getImg()).into(holder.img1);

package com.example.logindemo;
import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    @Override

            return false;
        }else{

                return false;

            Toast.makeText(this,"密码小于六位数",Toast.LENGTH_SHORT).show();
            return false;
        }

        return  true;
