需要将选定的图像从SD卡发送到ASP.net Web服务器 [英] Need to send the selected image from SDcard to an ASP.net web server

问题描述

我需要将所选图像发送到Web服务器。从SD卡中选择图像的代码如下所示。我在谷歌搜索了很多次。但仍然没有找到适合我的问题的解决方案。任何人都可以建议我如何将选定的图像发送到Web服务器。 Web服务器是ASP.net Web服务器。我发现很多代码将数据发送到互联网上的php web服务器，但没有找到发送到ASP.net Web服务器的代码。请帮帮我。我是android的新手。所以我不知道通过网络服务器发送图像/视频数据的步骤。

 //我添加了一个按钮来选择图像
 
按钮imgbrowse =（按钮）findViewById（R.id.imgbrowse）; 
 
 imgbrowse.setOnClickListener（new OnClickListener（）
 {
 
 @Override 
 public void onClick（View v）{
 // TODO自动生成的方法stub 
 Intent i = new Intent（Intent.ACTION_PICK，android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI）; 
 startActivityForResult（i，RESULT_LOAD_IMAGE）; 
 
} 
}）; 
 
 @Override 
 protected void onActivityResult（int requestCode，int resultCode，Intent data）{
 // TODO自动生成的方法stub 
 super.onActivityResult（requestCode， resultCode，data）; 
 if（requestCode == RESULT_LOAD_IMAGE&& resultCode == RESULT_OK&& null！= data）{
 Uri selectedImage = data.getData（）; 
 String [] filePathColumn = {MediaStore.Images.Media.DATA}; 
 
 Cursor cursor = getContentResolver（）。query（selectedImage，
 filePathColumn，null，null，null）; 
 cursor.moveToFirst（）; 
 
 int columnIndex = cursor.getColumnIndex（filePathColumn [0]）; 
 
 //图像所在的路径存储在字符串变量
 
 String picturePath = cursor.getString（columnIndex）; 
 cursor.close（）; 
 
 //在图像视图中显示所选图像。 
 
 ImageView imageView =（ImageView）findViewById（R.id.imageView1）; 
 imageView.setImageBitmap（BitmapFactory.decodeFile（picturePath））; 
 
 //显示所选图像的路径
 
 TextView tv =（TextView）findViewById（R.id.textView5）; 
 tv.setText（picturePath）; 
 
} 
} 

解决方案

您可以使用HTTP客户端将图像发送到服务器

I need to send the selected image to a web server. The code for selecting the image from the sdcard is shown below. I have searched many times in google. But still not finding a proper solution to my problem. Can anyone please suggest me how to send the selected image to a web server. The web server is a ASP.net web server. I have found many code to send data to php web server on the internet, but didn't find a code to send to an ASP.net web server. Please help me out. I'm new to android. So I didn't know the steps of sending image/ video data through a web server.

// I have added a button to select the image

Button imgbrowse=(Button)findViewById(R.id.imgbrowse); 

imgbrowse.setOnClickListener(new OnClickListener() 
{

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(i, RESULT_LOAD_IMAGE);

        }
});

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);

//the path where the image is located is stored in string variable

String picturePath = cursor.getString(columnIndex);         
        cursor.close();

    //Displaying the selected image in the image view. 

        ImageView imageView = (ImageView) findViewById(R.id.imageView1);
        imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

    //Displaying the path of the selected image

        TextView tv=(TextView)findViewById(R.id.textView5);
        tv.setText(picturePath);

    }
}
