Android 使用HttpClient和第三方MIME文件上传类库，实现文件上传

转自：/article/2946362.html

MainActivity中定义的方法

private void httpUpload() {

//定义HttpClient对象
HttpClient client = new DefaultHttpClient();
//获得HttpPost对象
HttpPost post = new HttpPost("http://192.168.1.106:8001/2012/upload.php");
post.addHeader("charset", HTTP.UTF_8);
//实例化
MultipartEntity me = new MultipartEntity();

try {

me.addPart("content",new StringBody("12cccafasdfasdf"));
me.addPart("title",new StringBody("csdnliwei"));
me.addPart("local",new StringBody("beijing"));
//设置流文件
me.addPart("file", new InputStreamBody(new FileInputStream("/mnt/sdcard/test.jpg"), "image/pjpeg", "fengjie.jpg"));

post.setEntity(me);
//获得响应消息
HttpResponse resp = client.execute(post);

if(resp.getStatusLine().getStatusCode()==200){

Toast.makeText(this, "文件上传文成！", 1).show();

}

} catch (Exception e) {

e.printStackTrace();
}

}

服务器端PHP程序：

<?php
header("Content-type:text/html;charset=utf-8");

print_r($_FILES['file']);

$filename = $_FILES['file']['name'];

if(!$_FILES['file']['error']){

if(move_uploaded_file($_FILES['file']['tmp_name'],"./upload/".$filename)){

echo "文件上传成功";

}else{
echo "文件上传失败le";
}

}else{

echo "文件上传错误";
}

?>

Android-HttpClient上传信息（包括图片）到服务端

需要下载apache公司下的HttpComponents项目下的HTTPCLIENT

----------地址为http://hc.apache.org/downloads.cgi

主要是用到了httpmime-4.1.2.jar包

android客户端：

以下是请求action的jsp表单（测试用）

<form action="AddFoodStyle" enctype="multipart/form-data" method="post">
<div style="width:300px;">
<s:textfield label="菜式名称" name="foodname"></s:textfield><br/>
<s:select name="foodstyle" list="list" label="菜式类别" listKey="Itemid" listValue="itemname"  >

</s:select><br/>
<s:textfield label="菜式价格" name="price"></s:textfield><br/>
<s:file label="菜式图片" name="foodimg"></s:file><br/>
<s:textarea label="菜式标签" name="foodtab" cols="20"  cssStyle=""></s:textarea><br/>
<s:textfield label="菜式状态" name="state"></s:textfield><br/>
<s:submit value="添加"/>
</div>
</form>

模拟构造上面的请求表单

private String url="http://192.168.2.189:8080/MyOrderMeal/AddFoodStyle";
HttpClient httpclient= new DefaultHttpClient();
HttpPost httpPost= new HttpPost(url);
MultipartEntity mulentity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
mulentity.addPart("foodname", new StringBody(foodname.getText().toString().trim()));
mulentity.addPart("foodstyle", new StringBody(foodstyle.getText().toString().trim()));
mulentity.addPart("price", new StringBody(foodprice.getText().toString().trim()));
//添加图片表单数据
FileBody filebody = new FileBody(this.image);
mulentity.addPart("foodimg",filebody );
mulentity.addPart("foodtab", new StringBody(foodtab.getText().toString().trim()));
mulentity.addPart("state", new StringBody("1"));
httpPost.setEntity(mulentity);
HttpResponse response =    httpclient.execute(httpPost);

if(response.getStatusLine().getStatusCode()==HttpStatus.SC_OK)
{
makeToase("上传成功",true);
if(this.image.exists())
this.image.delete();
}
else
{
makeToase("上传失败",true);
}

服务端：action的配置

<action name="AddFoodStyle" class="com.ordermeal.xiao.action.AddFoodStyle">

<result name="success" type="redirect">/ShowAddFoodStyle</result>

</action>

action的编写

public class AddFoodStyle extends ActionSupport{
/**
*
*/
private static final long serialVersionUID = -8380963167787044860L;

private String foodname;
private Integer foodstyle;
private Double price;

//接收上传文件
private File foodimg;
private String foodimgFileName;
private String foodimgContentType;

private String foodtab;
private Integer state;
@Override
public String execute() throws Exception {

FoodStyleDao fsd = DaoFactory.getFoodStyleDao();
FoodStyle  foodstyleob= new FoodStyle();
foodstyleob.setFoodname(foodname);
foodstyleob.setMystyletype(foodstyle);
foodstyleob.setFoodprice(price);
foodstyleob.setImageurl(foodimgFileName);
foodstyleob.setFoodtab(foodtab);
foodstyleob.setFdstystate(state);
fsd.addFoodStyle(foodstyleob);
String path= ServletActionContext.getServletContext().getRealPath("/");
//保存上传文件
FileUtil.copyFile(foodimg, path+"/images/"+foodimgFileName);
return SUCCESS;
}
