android 利用httpclient上传图片

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:filelabel="菜式图片"name="foodimg"></s:file><br/>

<s:textarealabel="菜式标签"name="foodtab"cols="20"cssstyle=""></s:textarea><br/>

<s:textfieldlabel="菜式状态"name="state"></s:textfield><br/>

<s:submitvalue="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();

HttpPosthttpPost=newHttpPost(url);

MultipartEntitymulentity=newMultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

mulentity.addPart("foodname",newStringBody(foodname.getText().toString().trim()));

mulentity.addPart("foodstyle",newStringBody(foodstyle.getText().toString().trim()));

        mulentity.addPart("price", new StringBody(foodprice.getText().toString().trim()));  

       //添加图片表单数据       

FileBodyfilebody=newFileBody(this.image);

mulentity.addPart("foodimg",filebody);

mulentity.addPart("foodtab",newStringBody(foodtab.getText().toString().trim()));

mulentity.addPart("state",newStringBody("1"));

httpPost.setEntity(mulentity);

HttpResponseresponse=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">

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

</action>

    action的编写

public class AddFoodStyle extends ActionSupport{

/**

*

*/

privatestaticfinallongserialVersionUID=-8380963167787044860L;

privateStringfoodname;

privateIntegerfoodstyle;

privateDoubleprice;

   

   //接收上传文件

    private File foodimg;

privateStringfoodimgFileName;

privateStringfoodimgContentType;

privateStringfoodtab;

    private Integer state;

、、、、省略get  set方法

@Override

publicStringexecute()throwsException{

FoodStyleDaofsd=DaoFactory.getFoodStyleDao();

FoodStylefoodstyleob=newFoodStyle();

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;

    }
