我试图发送多个图像到服务器,所以我存储一切图像,但在我需要发送到服务器的时候。


 conn.setRequestProperty("image", multimgss); 

错误


The method setRequestProperty(String, String) in the type URLConnection is not applicable for the arguments (String, ArrayList<String>)..

你可以将 String 参数作为字段发送给 setRequestProperty()

问题:在第二个参数中,你正在传递 ArrayList<String>

尝试通过 setRequestProperty() 逐一传递 multimgss的每个元素


 FileInputStream fileInputStream = new FileInputStream(sourceFile);
 URL url = new URL(upLoadServerUri);

//Open a HTTP connection to the URL
 conn = (HttpURLConnection) url.openConnection(); 
 conn.setDoInput(true);//Allow Inputs
 conn.setDoOutput(true);//Allow Outputs
 conn.setUseCaches(false);//Don't use a Cached Copy
 conn.setRequestMethod("POST");
 conn.setRequestProperty("Connection","Keep-Alive");
 conn.setRequestProperty("ENCTYPE","multipart/form-data");
 conn.setRequestProperty("Content-Type","multipart/form-data;boundary=" + boundary);

 conn.setRequestProperty("name", pname);
 conn.setRequestProperty("categoryid", catsids);
 conn.setRequestProperty("skucode", pskucode);
 conn.setRequestProperty("sale_rate", psalerate);
 conn.setRequestProperty("purchase_rate", ppurchaserate);
 conn.setRequestProperty("weight", pweight);
 conn.setRequestProperty("weighttype", pweighttype);
 conn.setRequestProperty("description", pdesc);


 conn.setRequestProperty("image", multimgss.get(i++)); 
//it will give i th element 

注意:来自 setRequestProperty()的Android开发人员文档

设置指定请求头字段的值。 值将只被当前URLConnection实例使用。 这里方法只能在建立连接之前调用。

因此,在建立连接之前,你需要每次调用这里方法

setRequestProperty 方法只接受 String 而不接受 ArrayList 。 从 ArrayList 获取 JSONArray 作为:


JSONArray jsonArrayImgs=new JSONArray();
 ArrayList<String> multimgss=new ArrayList<String>();
 for (String string : multimgss)
 {
 jsonArrayImgs.put(string);
 }

现在将 jsonArrayImgs 传递给 setRequestProperty:


conn.setRequestProperty("image", jsonArrayImgs.toString()); 

编辑:

sourceFileUrinull 因此,请更新适配器的getItem 方法:


public String getItem(int position) {
 return arrayList.get[position];
 }

现在在 onItemClickGridView asign中选择图像路径为 sourceFileUri:


public void onItemClick(AdapterView<?> parent, 
 View v, int position, long id) 
 { 
 imagepath=objImageAdapter.getItem(position);
 }
