OkHttp3最简单封装
一、使用
1，异步Get
String url="http://www.2014nut.com/app.php";
OkHttpManager.getAsyn(url, newOkHttpManager.ResultCallback() {
@Override
public void onError(Call call,Exception e) {
}
@Override
public void onResponse(Call call,Response response) {
}
});
2,异步Post
String url="http://www.2014nut.com/app.php";
Map map=newHashMap();
map.put("id","1");
OkHttpManager.postAsyn(url, newOkHttpManager.ResultCallback() {
@Override
public void onError(Call call,Exception e) {
}
@Override
public void onResponse(Call call,Response response) {
}
},map);
3，Post多文件上传，带参数
String url="http://www.2014nut.com/app.php";
Map map=newHashMap();
map.put("id","1");
OkHttpManager.postFileAsyn(url, newFile[]{}, newOkHttpManager.ResultCallback() {
@Override
public void onError(Call call,Exception e) {
}
@Override
public void onResponse(Call call,Response response) {
}
},map);
2、封装类：
importjava.io.File;
importjava.io.IOException;
importjava.net.FileNameMap;
importjava.net.URLConnection;
importjava.util.Map;
importokhttp3.Call;
importokhttp3.Callback;
importokhttp3.FormBody;
importokhttp3.MediaType;
importokhttp3.MultipartBody;
importokhttp3.OkHttpClient;
importokhttp3.Request;
importokhttp3.RequestBody;
importokhttp3.Response;
