retrofit使用

定义接口

package com.weedfs.client.yj.weedfsClient.Interface;

import com.weedfs.client.yj.weedfsClient.dto.Upload;

import retrofit.client.Response;
import retrofit.http.GET;
import retrofit.http.Multipart;
import retrofit.http.POST;
import retrofit.http.Part;
import retrofit.http.Path;
import retrofit.http.Query;
import retrofit.http.Streaming;
import retrofit.mime.TypedInput;

public interface DirectApiI {
    @Multipart
    @POST("/submit")
    Upload upload(@Query("collection") String collection, @Query("replication") String replication,
                @Part("file") TypedInput input);
    @GET("/{fid}")
    @Streaming
    Response get(
            @Path("fid") String id);
}

使用接口

package com.weedfs.client.yj.weedfsClient;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.nio.file.Paths;

import retrofit.RestAdapter;
import retrofit.client.Response;
import retrofit.mime.TypedFile;

import com.weedfs.client.yj.weedfsClient.Interface.DirectApiI;
import com.weedfs.client.yj.weedfsClient.dto.Upload;

/**
 * Hello world!
 *
 */
public class App {
    public static void main(String[] args) {
        DirectApiI dai = new RestAdapter.Builder().setEndpoint("http://10.0.40.59:9335").build()
            .create(DirectApiI.class);
        Upload upload = dai.upload(
            "testClient",
            "001",
            new TypedFile("text/plain", Paths.get(
                "/Users/weedfs-java/src/resource/hello2.txt").toFile()));
        System.out.println(upload.getFid() + " " + upload.getFilename() + " " + upload.getFileUrl() + " "
                           + upload.getSize());
        Response rs = dai.get(upload.getFid());
        String filename = "/Users/weedfs-java/src/resource/hello3.txt";
        InputStream is = null;
        FileOutputStream fos = null;
        try {
            fos = new FileOutputStream(filename);
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        try {
            is = rs.getBody().in();

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        int ch = 0;  
        try {  
            while((ch=is.read()) != -1){  
                fos.write(ch);  
            }  
        } catch (IOException e1) {  
            e1.printStackTrace();  
        } finally{              //关闭输入流等（略）  
            try {
                fos.close();
                is.close();  
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }  
        }  
        System.out.println(rs.getStatus());

    }
