总体流程 定接口请求—》失败成功方法 每一层都要实现接口写逻辑
1.先定义最外层接口Get和Post可以自己添加
public interface IHttpProcessor {
//这是工作的接口
//Post
void Post(String url, Map<String,Object> params,ICallBack callBack);
//Get
void Get(String url, Map<String,Object> params,ICallBack callBack);
//Del
//Update
}
2.在定义一个失败成功接口
interface ICallBack {
//这里代表网络请求的行为
void onSuccess(String result);
void onFailure(String erren);
}
3.然后从成功开始解析字符串 失败的话就不用写了因为不需要解析
//这些就是网络请求的规范
//这个目的就是将网络层的数据String转换成Result这个泛型 达到成功解析的效果 当然retrofit底层已经封装好了
public abstract class HttpCallback<Result> implements ICallBack {
@Override
public void onSuccess(String result) {
Gson gson = new Gson();
Class<?> cls=analysisClazInfo(this);
Result objectResult = (Result) gson.fromJson(result, cls);
onSuccess(objectResult);
}
//这是为了将转变之后的返回值数据直接传到上面去 这是为了能够成功的将String类型数据转换成Result类型
public abstract void onSuccess(Result result);
public static Class<?> analysisClazInfo(Object object){
Log.d("aaaaaa", "analysisClazInfo: "+object.getClass().toString());
//得到object的超类
Type genericSuperclass = object.getClass().getGenericSuperclass();
Log.d("aaaaaa", "onSuccess: "+genericSuperclass.toString());
//将超类强转成参数化类型得到实际真正的类型 整个继承类的类名列表
Type[] actualTypeArguments = ((ParameterizedType) genericSuperclass).getActualTypeArguments();
Log.d("aaaaaa", "onSuccess: "+actualTypeArguments[0]);
return (Class<?>) actualTypeArguments[0];
}
}
4.然后写Get和Post这层代码 这一层是用的代理模式
//这一层就是代理层 将数据传递到真正工作的类
//这里是代理层 为了将View层直接访问工作接口
public class HttpProxy implements IHttpProcessor {
//公共需要的东西
private static IHttpProcessor mIHttpProcessor = null;
private Map<String,Object> mParams = null;
private HttpProxy(){
mParams=new HashMap<>();
}
//这只是个单利
private static HttpProxy httpProxy;
public static HttpProxy obtain(){
synchronized (HttpProxy.class){
if(httpProxy==null){
httpProxy=new HttpProxy();
}
}
return httpProxy;
}
public static void init(IHttpProcessor httpProcessor){
mIHttpProcessor=httpProcessor;
}
@Override
public void Post(String url, Map<String, Object> params, ICallBack callBack) {
final String finalUrl = appendParams(url, params);
mIHttpProcessor.Post(finalUrl,params,callBack);
}
@Override
public void Get(String url, Map<String, Object> params, ICallBack callBack) {
final String finalUrl = appendParams(url, params);
mIHttpProcessor.Get(finalUrl,params,callBack);
}
//这是接口后面的字符串的拼接
public static String appendParams(String url,Map<String,Object> params){
if (params == null || params.isEmpty()){
return url;
}
StringBuilder stringBuilder = new StringBuilder(url);
//如果这个Url查到？符号的指数是零 那么表示没有就添加
if (stringBuilder.indexOf("?")<=0) {
stringBuilder.append("?");
}else {//有的话就判断Url是不是？结尾的 如果不是就添加&字符
if(!stringBuilder.toString().endsWith("?")){
stringBuilder.append("&");
}
}
for (Map.Entry<String,Object> entry : params.entrySet()) {
stringBuilder.append(entry.getKey()).append("=").append(entry.getValue().toString());
}
return stringBuilder.toString();
}
//Url不允许有空格等字符，如果参数值有空格，需要此方法转换
private static String encode(String str){
try {
return URLEncoder.encode(str,"utf-8");
} catch (UnsupportedEncodingException e) {
//针对不支持的编码时报错，utf-8应该支持
Log.d("aaaaaa", "encode: "+e.toString());
throw new RuntimeException(e);
}
}
}
5.最后一个就是工作类 就是从上面的那个类传递过来的 这里的话可以换框架
public class OkhttpProcessor implements IHttpProcessor {
private OkHttpClient mOkHttpClient;
private Handler myHandler;
public OkhttpProcessor(){
mOkHttpClient = new OkHttpClient();
myHandler = new Handler();
}
@Override
public void Post(String url, Map<String, Object> params, final ICallBack callBack) {
Log.d("aaaaaa", "Post: ");
RequestBody requestBody = appendBody(params);
Request request = new Request.Builder()
.url(url)
.post(requestBody)
.header("User-Agent", "a")//这句话必须加 不然会报错 因为当时okhttp开发的时候没有考虑到中文服务器和编解码 后面的a代表中国的
.build();
mOkHttpClient.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, final IOException e) {
//运行在主线程将数据传递出去
myHandler.post(new Runnable() {
@Override
public void run() {
callBack.onFailure(e.toString());
}
});
}
@Override
public void onResponse(Call call, final Response response) throws IOException {
if(response.isSuccessful()){
final String result = response.body().string();
//运行在主线程将数据传递出去
myHandler.post(new Runnable() {
@Override
public void run() {
callBack.onSuccess(result);
}
});
}else {
//运行在主线程将数据传递出去
myHandler.post(new Runnable() {
@Override
public void run() {
callBack.onFailure(response.toString());
}
});
}
}
});
}
@Override
public void Get(String url, Map<String, Object> params, ICallBack callBack) {
}
//body拼接
private RequestBody appendBody(Map<String,Object> params){
FormBody.Builder body = new FormBody.Builder();
if(params == null || params.isEmpty()){
return body.build();
}
for (Map.Entry<String,Object> entry:params.entrySet()) {
body.add(entry.getKey(),entry.getValue().toString());
}
return body.build();
}
}
6.gson的话就是实体类 你可以自己创建我这边也给你打包好了 一并奉上
public class gson {
/**

7.在使用前的话还需要初始化一下 创建一个类在app启动时知道执行里面的方法
public class MyAppcation extends Application {
@Override
public void onCreate() {
super.onCreate();
//代理层和框架层建立连接
HttpProxy.init(new OkhttpProcessor());
}
}
8.然后在你的清单文件里面添加这一句
9.然后就可以正常使用
public class MainActivity extends AppCompatActivity {
private String url="http://c.3g.163.com/photo/api/set/0001%2F2250173.json";
private HashMap<String,Object> params=new HashMap<String,Object>();
private TextView textView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView=findViewById(R.id.tv_show);
}
public void onClick(View view) {
HttpProxy.obtain().Post(url,params,new HttpCallback<gson>(){
@Override
public void onFailure(String erren) {
Log.d("aaaaaa", "onFailure: "+erren.toString());
}
@Override
public void onSuccess(gson result) {
textView.setText(result.toString());
}
});
}
}
