Android uploads files to PHP server

The first two months had the privilege of attending a free training program and developing a small piece of software. Found that asynchttpclient is really useful.

Straight to the theme, Android uploads files to the PHP server:

1.PHP Terminal Server:

<?php//link database include ("config/db.php");//Get user Id$userid = $_post[' userid '];//process upload file $base_path = "upload/"; $fileName =$_files[' file ' [' Name ']; $name =explode ('. ', $fileName);      $userpicads = $base _path.  ' User_ '. $userid. '. '. $name [1]; /* Return Status code: 300: Process Success 301: Server Exception */$status =301;if (Move_uploaded_file ($_files [' file '] [' tmp_name '], $userpicads)) {  $ status=300; } else {  $status = 301;} If the file is saved successfully, update the database if ($status ==300) {$sql = "update mh_user set userpicads= ' {$userpicads} ' where id={$userid}"; $pdo EXEC ($sql);} The output returns the result $ret = Array (' status ' = $status); echo Json_encode ($ret);? >

2. Android Add Network permissions

<uses-permission android:name= "Android.permission.INTERNET"/>

　　

3. Android Import the following jar packages (which can be easily downloaded to):

Android-async-http-1.4.7.jar (required)
Gson-2.1.jar (optional, parsing JSON format)
Httpcore-4.4.4.jar (optional, with Android Stutio may also need to import this)

4. Android Main code:

int userid = 1; String username = "HelloWorld"; String filepath = "/mnt/sdcard/download/mm.jpg"; String uploadurl = "http://192.168.1.103/test/upload.php"; Btn_upload.setonclicklistener (new View.onclicklistener () {@Overridepublic void OnClick (View v) {asynchttpclient client = new Asynchttpclient (); Requestparams params = new Requestparams ();//Add Parameter Params.put ("userid", UserID);p arams.put ("username", username); try {/ /Add Files params.put ("File", new file (filepath));} catch (FileNotFoundException e) {e.printstacktrace ();} Client.post (Uploadurl, params, new Asynchttpresponsehandler () {@Overridepublic void onsuccess (int i, Org.apache.http.header[] headers, byte[] bytes) {try {//Get back the contents of string resp = new string (bytes, "utf-8");//Handle the returned content here, such as parsing json or something ...} catch (Unsupportedencodingexception e) {e.printstacktrace ();}} @Overridepublic void onfailure (int i, org.apache.http.header[] headers, byte[] bytes, throwable throwable) {// Handle connection failed processing here ...});});

How PHP renames the uploaded file:

Android Studio may not be able to find Org.apache.http.Header, refer to:
