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https://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 >
<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="https://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" >
<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;
、、、、省略get set方法
@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;
}
