Question

使用已弃用的http实现，可以从有效负载或属性中动态设置出站http端点上的URL：

 public class AddAircraftFragment extends Fragment
 {
RecyclerView recyclerView;
private static final int SELECT_PICTURE = 111;


public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState)
{

    View rootView =  inflater.inflate(R.layout.fragment_add_aircraft, container, false);

    recyclerView=(RecyclerView)rootView.findViewById(R.id.recyclerAircraftAdd);
    RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getActivity());
    recyclerView.setLayoutManager(layoutManager);
    AircraftAdapter adapter = new AircraftAdapter();
    recyclerView.setAdapter(adapter);


    return rootView;

}


@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    BitmapFactory.Options btmapOptions;

    if (requestCode == SELECT_PICTURE && resultCode == Activity.RESULT_OK) {
        final Uri selectedImageUri = data.getData();
        String tempPath = getPath(selectedImageUri, this.getActivity());
        final Bitmap bm;
        btmapOptions = new BitmapFactory.Options();
        btmapOptions.inSampleSize = 2;
        bm = BitmapFactory.decodeFile(tempPath, btmapOptions);
        AircraftAdapter.bmp = bm;
    }
}



        public String getPath(Uri uri, Activity activity)
        {
            String[] projection = {MediaStore.MediaColumns.DATA};
            Cursor cursor = activity.managedQuery(uri, projection, null, null, null);
            int column_index = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA);
            cursor.moveToFirst();
            return cursor.getString(column_index);
        }


        public void onAttach(Activity activity)
{
    super.onAttach(activity);
}


public void onDetach()
{
    super.onDetach();
}

是否可以使用新的http请求连接器执行此操作？

是的，确实如此。这是一个简单的例子：

<http:request-config 
    name="HTTP_Request_Configuration" 
    host="#[flowVars.address]" 
    port="80" 
    basePath="/" 
    doc:name="HTTP Request Configuration"/>

<flow name="httpFlow">

    ...

    <set-variable 
        variableName="address" 
        value="#[message.inboundProperties.'http.query.params'.site]" 
        doc:name="Set site address variable"/>

    <http:request 
        config-ref="HTTP_Request_Configuration" 
        path="/" 
        method="GET" 
        doc:name="Get dynamic HTTP"/>
</flow>

只需使用您需要的MEL表达式定义主机属性。

主机= “＃[flowVars.someVariable]”
