okhttp3.14.x 上傳不存在的文件後，再上傳文件400

增加NetworkInterceptor，如下

/**
 * 解決在okhttp3的3.14.x版本，當上傳不存在的文件時，再重新上傳存在的文件，okhttp還複用上次的連接，但是
 * 上次的連接中已經write了部分數據，此髒數據導致發生400錯誤
 *
 *

public class RemoveDirtyConnIntercepter implements Interceptor {

    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();
       Connection connection =  chain.connection();
        Response response = null;
       try{
           response = chain.proceed(request);
       }catch (IOException e){
           if(connection instanceof RealConnection) {
               RealConnection realConnection = (RealConnection) connection;
               Method noNewExchanges = RefUtil.getDeclaredMethod(realConnection,"noNewExchanges");
               if(noNewExchanges!=null){
                   try{
                       noNewExchanges.invoke(realConnection);
                   }catch (Exception f){
                       f.printStackTrace();
                   }

               }
