最近手头上需要批量上传一些保存到SD卡图片由于简单，过于忘记，写在博客中吧！同时也希望能帮到大家!
一 、 以下是一个Service类
package cn.com.service;
import java.io.File;
import java.util.ArrayList; import java.util.List;import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.multipart.FilePart; import org.apache.commons.httpclient.methods.multipart.MultipartRequestEntity; import org.apache.commons.httpclient.methods.multipart.Part; import org.apache.commons.httpclient.methods.multipart.StringPart;import android.util.Log;
/**
* 批量上传服务类 * @author ChonZY * */ public class DataService { /** * 批量上传图片 * @param path 服务器地址 * @param name 用户名 * @param filePath sd卡图片路径 * @return * @throws Exception */ public static String sendDataByHttpClientPost(String path ,String name,List<File> filePath)throws Exception{ List<Part> partList = new ArrayList<Part>(); partList.add(new StringPart("user", name)); partList.add(new StringPart("picnumber", "4")); for (int i = 0; i < filePath.size(); i++) { String picPath = filePath.get(i).getPath(); Log.i("Other", "服务类 图片路径Service _ PicPath ="+picPath); partList.add(new FilePart("file", new File(filePath.get(i).getPath()))); } // 实例化上传数据的数组 // Part [] parts = {new StringPart("user", name),new FilePart("file", new File(filePath))}; Part[] parts = partList.toArray(new Part[0]); Log.i("Other","new Part[0] _size:"+ parts.length); PostMethod filePost = new PostMethod(path); filePost.setRequestEntity(new MultipartRequestEntity(parts, filePost.getParams())); org.apache.commons.httpclient.HttpClient client = new org.apache.commons.httpclient.HttpClient(); client.getHttpConnectionManager().getParams().setConnectionTimeout(5000); int status = client.executeMethod(filePost); Log.i("Other", "返回结果:"+status); if(status == 200){ System.out.println( filePost.getResponseCharSet()); String result = new String(filePost.getResponseBodyAsString()); System.out.println("--"+result); return result; }else{ throw new IllegalStateException("服务器状态异常"); } } /** * 单次上传图片or文件 * @param path * @param name * @param filePath * @return * @throws Exception */ public static String sendDataByHttpClientPost(String path ,String name,String filePath)throws Exception{ /*List<Part> partList = new ArrayList<Part>(); partList.add(new StringPart("user", name)); for (int i = 0; i < 4; i++) { partList.add(new FilePart(name, FilePart())); }*/ // 实例化上传数据的数组 Part [] parts = {new StringPart("user", name),new FilePart("file", new File(filePath))}; PostMethod filePost = new PostMethod(path); filePost.setRequestEntity(new MultipartRequestEntity(parts, filePost.getParams())); org.apache.commons.httpclient.HttpClient client = new org.apache.commons.httpclient.HttpClient(); client.getHttpConnectionManager().getParams().setConnectionTimeout(5000); int status = client.executeMethod(filePost); Log.i("Other", "返回结果:"+status); if(status == 200){ System.out.println( filePost.getResponseCharSet()); String result = new String(filePost.getResponseBodyAsString()); System.out.println("--"+result); return result; }else{ throw new IllegalStateException("服务器状态异常"); } }}

二、 以下是Activity中调用Service类的方法，进行批量上传图片
/**
* 批量上传图片 */ private void filePostForSDPic() { new Thread(){ public void run() { try { saveDir = Environment.getExternalStorageDirectory()+ "/chonPic"; String filePath = saveDir; String path = "http://这里的路径就不贴上去了，保证成功并万无一失"; String result = DataService.sendDataByHttpClientPost(path, "admin", fileList); Toast.makeText(MainActivity.this,"pic_haha:"+ result, 0).show(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } }; }.start(); }---------------------------------------------------------------------------------------
调用批量上传方法需要引入阿帕奇3 个jar包
1. commons-codec-1.3.jar
2. commons-httpclient-3.1.jar
3. commons-logging-1.1.jar
