問題描述

我正在嘗試使用附加值將圖像從 android 手機上傳到 php 服務器，方法是 post我的 php 文件看起來像這樣

I am trying to upload image from android phone to php server with additional values,the method is post my php file look like this

if($_POST['val1']){
  if($_POST['val2']){
     if($_FILE['image']){
      ...... 
    }
  }
}else{
echo "Value not found";
}

我正在做的是

URL url=new URL("http://www/......../myfile.php");
HttpURLConnection con=(HttpURLConnection) url.openConnection();
con.setDoInput(true);
con.setDoOutput(true);
con.setUseCaches(false);
con.setRequestMethod("POST");//Enable http POST
con.setRequestProperty("Connection", "Keep-Alive");
con.setRequestProperty("Content-Type", "multipart/form-data;boundary="+"****");
connection.setRequestProperty("uploaded_file", imagefilePath);
DataOutputStream ostream = new DataOutputStream( con.getOutputStream());
String res=("Content-Disposition: form-data; name="val1""+val1+"****"+
"Content-Disposition: form-data; name="val2""+val2+"****"
"Content-Disposition: form-data; name="image";filename="" + imagefilePath +"""+"****");
outputStream.writeBytes(res);

我的實際問題是沒有發布值，所以首先如果條件為假，否則執行其他部分，即未找到值請幫幫我

my actual problem is values are not posting so first if condition get false and else section is executed that is it give value not found please help me
