Android notes: file + parameter upload requests

Android notes: file + parameter upload requests

Step 1: we need the support of two jars, which will be provided later.

Step 2: Create a project

Below is the most important code

Package com. example. testpaizhao;


Import java. io. File;
Import java. io. UnsupportedEncodingException;
Import java. nio. charset. Charset;


Import org. apache. http. HttpResponse;
Import org. apache. http. HttpStatus;
Import org. apache. http. client. HttpClient;
Import org. apache. http. client. methods. HttpPost;
Import org. apache. http. entity. mime. MultipartEntity;
Import org. apache. http. entity. mime. content. FileBody;
Import org. apache. http. entity. mime. content. StringBody;
Import org. apache. http. impl. client. DefaultHttpClient;
Import org. apache. http. util. EntityUtils;


Import android. app. Activity;
Import android. OS. Bundle;
Import android. util. Log;


Public class testphone extends Activity {
@ Override
Protected void onCreate (Bundle savedInstanceState ){
// TODO Auto-generated method stub
Super. onCreate (savedInstanceState );
SetContentView (R. layout. face_recognition_activity );
New Thread (){
Public void run (){
Try {
Mai ();
} Catch (Exception e ){

E. printStackTrace ();
}
};
}. Start ();

}
Private void mai () throws Exception {
// Upload images to the server
HttpPost httpPost = new HttpPost (server address );
// Set Transfer Parameters
File file1 = new File ("/mnt/sdcard/yangtest.txt ");

MultipartEntity reqEntity = new MultipartEntity ();
ReqEntity. addPart ("vice_id ",
New StringBody ("1", Charset
. ForName (org. apache. http. protocol. HTTP. UTF_8 )));
ReqEntity. addPart ("m ",
New StringBody ("15261651603", Charset
. ForName (org. apache. http. protocol. HTTP. UTF_8 )));
ReqEntity. addPart ("f ",
New StringBody ("66666666666", Charset
. ForName (org. apache. http. protocol. HTTP. UTF_8 )));
// If (! File1.getAbsoluteFile (). equals (""))
//{
// FileBody fileBody = new FileBody (file1 );
// ReqEntity. addPart ("pic", fileBody );
//}
//
// StringBody type = new StringBody ("wish ");
// ReqEntity. addPart ("type", type );
// If (type. equals ("wish ")){
// StringBody temp = new StringBody ("1 ");
// ReqEntity. addPart ("temp", temp );
//}
// Else
//{
// StringBody temp = new StringBody ("");
// ReqEntity. addPart ("temp", temp );
//}



HttpPost. setEntity (reqEntity );
// Obtain the default HttpClient
HttpClient httpclient = new DefaultHttpClient ();
// Get HttpResponse
HttpResponse httpResponse = httpclient.exe cute (httpPost );
// HttpStatus. SC _ OK indicates that the connection is successful.
If (httpResponse. getStatusLine (). getStatusCode () = HttpStatus. SC _ OK)
{
// Obtain the returned string
String strResult = EntityUtils. toString (httpResponse. getEntity ());
System. out. println ("yes! ");
Log. I ("test", "no" + strResult. toString ());

}
Else
{
Log. I ("test", "no ");
}
}

}

This class can be used to directly upload file + String information and modify it as needed.

Finally, do not forget to add network permissions to the list file.

Note: How can I import the previously recorded data after the Android phone is flushed?

If you are using the Professional Edition, you can directly synchronize the newly installed notes;

If you are an ordinary version and you have backed up your computer, you can use the Backup recovery function;

My Android mobile phone keeps track of the changes in network data after the backup file is read?

What changes do you mean?
No,
Read the file you backed up. What is your backup like? What is it like after reading it?
