前面几篇博客分析了Volley的源码，加上最近在看《Head First设计模式》这本书（不得不说老外的书是真的不错，推荐），于是基于鸿洋大神的OkhttpUtil的源码和OkHttp的源码，加上自己的理解，封装了这么一个工具类。
1.GET
2.POST
3.post传json
4.post传文件（不支持大文件类型）
5.自定义拦截器
6.gson
7.配置URL
8.全局URL,HEADER,拦截器
1.单例模式保证全局请求队列
2.weakreference持有Activity，支持onFinish()回调，防止内存泄漏
3.支持全局配置URL,HEADER
4.链式调用
5.增加过滤器
1.支持cookie
2.支持大文件
3.支持上传文件进度回调
4.支持https
5.构思ing...
Step 1. Add the JitPack repository to your build file Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency
dependencies {
compile 'com.github.sdfdzx:XVolley:v1.0.1'
}
XVolley.create(getApplicationContext());
通过调用init(Config config)方法，Config通过BaseConfigBuilder构建。
Map<String, String> header = new HashMap<>();
header.put("user-token", "AEUHY98QIASUDH");
BaseConfigBuilder config = new BaseConfigBuilder();
config.baseUrl("http://127.0.0.1/get.php")
.addParam("client", "Android")
.addParam("position", "北京")
.addHeaders(header)
.addIntercept(new Interceptor() {
@Override
public Request intercept(Chain chain) {
Request request = chain.request(); LogUtil.log("intercept","baseIntercept:"+request.getUrl());
return request;
}
});
XVolley.create(getApplicationContext())
.init(config.build());
XVolley.getInstance()
.doGet()
.url("http://127.0.0.1/get.php")
.addParam("name", "xuan")
.build()
.execute(this, new CallBack<String>() {
@Override
public void onSuccess(Context context, String response) {
}
});
这里的.url()方法会覆盖掉全局配置的URL,如果使用全局的URL，直接调用addParam方法即可，根据自己需求使用。
XVolley.getInstance()
.doPost()
.url("http://127.0.0.1/post.php")
.addParam("user", "xuan")
.build()
.execute(this, new CallBack<String>() {
@Override
public void onSuccess(Context context, String response) {
Log.e("Success", response);
}
});
weather weather = new weather();
weather.setCity("北京");
weather.setMessage("这是一条带json的post请求");
//post请求带json
XVolley.getInstance()
.doPostString()
.url("http://127.0.0.1/stringpost.php")
.content(new Gson().toJson(weather))
.build()
.execute(this,new CallBack<String>(){
@Override
public void onSuccess(Context context, String response) {
Log.e("Success", response);
}
});
支持多文件，多参数。
XVolley.getInstance()
.doPostFile()
.url("http://127.0.0.1/filex.php")
.addParam("name","xuan")
.addFile("txt", "bb.txt", Environment.getExternalStorageDirectory() + "/bb" +
".txt")
.addFile("png", "aa.txt", Environment.getExternalStorageDirectory() + "/aa" +
".png")
.build()
.execute(MainActivity.this, new CallBack<String>() {
@Override
public void onSuccess(Context context, String response) {
LogUtil.log("success",response);
}
});
只需要在链式调用中加上goGson(Class c)方法，传入Gson对应的class类型。所有类型请求都可以。
XVolley.getInstance()
.doGet()
.url( "http://www.sojson.com/open/api/weather/json.shtml")
.addParam("city", "北京")
.addHeaders(header)
.goGson(weather.class)
.build()
.execute(MainActivity.this, new CallBack<weather>() {
@Override
public void onSuccess(Context context, weather response) {
Log.e("Success", response.getCity());
}
});
实现Interceptor接口的intercept方法。
public interface Interceptor {
Request intercept(Chain chain);
interface Chain {
Request request();
}
}
(1)支持全局过滤器
Map<String, String> header = new HashMap<>();
header.put("user-token", "AEUHY98QIASUDH");
BaseConfigBuilder config = new BaseConfigBuilder();
config.baseUrl("http://127.0.0.1/get.php")
.addParam("client", "Android")
.addParam("position", "北京")
.addHeaders(header)
.addIntercept(new Interceptor() {
@Override
public Request intercept(Chain chain) {
Request request = chain.request(); LogUtil.log("intercept","baseIntercept:"+request.getUrl());
return request;
}
});
XVolley.create(getApplicationContext())
.init(config.build());
(2)支持单独过滤器
Map<String, String> header = new HashMap<>();
header.put("APP-Secret", "ad12msa234das232in");
XVolley.getInstance()
.doGet()
.url(
"http://www.sojson.com/open/api/weather/json.shtml")
.addParam("city", "北京")
.addHeaders(header)
.goGson(weather.class)
.build()
.addInterceptor(new Interceptor() {
@Override
public Request intercept(Chain chain) { LogUtil.log("intercept","custom");
Request request = chain.request();
String url = request.getUrl();
if (url.contains("sojson")) {
request.cancel();
return request;
}
return request;
}
})
.execute(MainActivity.this, new CallBack<weather>() {
@Override
public void onSuccess(Context context, weather response) {
Log.e("Success", response.getCity());
}
});
(3)支持全局+单独 递归调用，先调用单独的过滤器再调用全局过滤器
可以实现ICallBack接口实现所有方法
public interface ICallBack<T> {
void onBefore();
void onSuccess(Context context, T response);
void onError(VolleyError error);
void onAfter();
void onFinish();
}
或者实现CallBack类，实现对应需要的方法。
public abstract class CallBack<T> implements ICallBack<T> {
@Override
public void onBefore() {
}
@Override
public void onSuccess(Context context, T response) {
}
@Override
public void onError(VolleyError error) {
}
@Override
public void onAfter() {
}
@Override
public void onFinish() {
}
}
onFinish方法对应请求过程中Activity销毁的回调，可用于回收资源，防止内存泄漏。
内部Listener使用WeakReference持有Activity对象，防止内存泄漏。
public abstract class WeakListener{
final WeakReference<Activity> activityWeakReference;
final ICallBack callBack;
public WeakListener(Context activity, ICallBack callBack) {
activityWeakReference = new WeakReference<Activity>((Activity) activity);
this.callBack = callBack;
}
}
