本文介绍了上传doc，pdf，xls等从android应用程序到php服务器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用这个代码。
这里是PHP代码。
$ b
if（$ _ SERVER ['REQUEST_METHOD'] =='POST'） {
$ image = $ _POST ['image'];
$ name = $ _POST ['name'];
require_once（'dbConnect.php'）;
$ sql =SELECT id FROM volleyupload ORDER BY id ASC;
$ res = mysqli_query（$ con，$ sql）;
$ id = 0;
while（$ row = mysqli_fetch_array（$ res））{
$ id = $ row ['id'];
}
$ path =uploads / $ id.doc;
$ actualpath =http://10.0.2.2/VolleyUpload/$path;
$ sql =INSERT INTO volleyupload（photo，name）VALUES（'$ actualpath'，'$ name'）;
if（mysqli_query（$ con，$ sql））{
file_put_contents（$ path，base64_decode（$ image））;
回显成功上传;
}
mysqli_close（$ con）;
} else {
echoError;
$ / code $ / pre
这里是Java代码
private void showFileChooser（）{
Intent intent = new Intent（）;
intent.setType（file / *）;
intent.setAction（Intent.ACTION_GET_CONTENT）;
startActivityForResult（Intent.createChooser（intent，Select Picture），
PICK_IMAGE_REQUEST）;
我在上传按钮上调用了asynTask。
if（v == buttonUpload）{
// uploadImage（）;
PostDataAsyncTask（）。execute（）;
doInBackground中的函数调用是
private void postFile（）{
try {
//要发布的文件
String textFile = Environment。 getExternalStorageDirectory（）
+/ Woodenstreet Doc.doc;
Log.v（TAG，textFile：+ textFile）;
//文件发布的URL
字符串postReceiverUrl =http://10.0.2.2/VolleyUpload/upload.php;
Log.v（TAG，postURL：+ postReceiverUrl）;
// new HttpClient
HttpClient httpClient = new DefaultHttpClient（）;
//发帖头
HttpPost httpPost = new HttpPost（postReceiverUrl）;
File file = new File（filePath.toString（））;
FileBody fileBody = new FileBody（file）;
MultipartEntity reqEntity = new MultipartEntity（
HttpMultipartMode.BROWSER_COMPATIBLE）;
reqEntity.addPart（file，fileBody）;
httpPost.setEntity（reqEntity）;
//执行HTTP发布请求
HttpResponse响应= httpClient.execute（httpPost）;
HttpEntity resEntity = response.getEntity（）;
if（resEntity！= null）{
String responseStr = EntityUtils.toString（resEntity）.trim（）;
Log.v（TAG，Response：+ responseStr）;
//你可以在这里添加一个if语句，并根据
//执行其他操作
}
} catch（NullPointerException e） {
e.printStackTrace（）;
} catch（Exception e）{
e.printStackTrace（）;
$ / code $ / pre
$ b $ p我得到的例外是
java.io.FileNotFoundException：content：/com.topnet999.android.filemanager/storage/0F02-250A/test.doc：打开失败：ENOENT （没有这样的文件或目录）
仿真器中有文件test.doc。
是否有任何我想念的代码，请帮助我。
或建议上传PDF到PHP服务器的教程。
在此之前感谢。
解决方案这里是我的问题的解决方案：
这里是php文件的代码 - file.php <？php
//显示文件信息只需检查文件或图像是否存在
echo'< pre>;
print_r（$ _ FILES）;
echo'< / pre>';
//显示POST数据只是检查字符串数据是否存在
echo'< pre>;
print_r（$ _ POST）;
echo'< / pre>';
$ file_path =images /;
$ file_path = $ file_path。 basename（$ _FILES ['file'] ['name']）;
$ b $ if（move_uploaded_file（$ _ FILES ['file'] ['tmp_name']，$ file_path））{
echofile saved success;
} else {
echo保存文件失败;
}？>
将这个文件放入测试命名文件夹内的Xampp的htdoc文件夹中（如果已经有测试文件夹， ，否则建立一个名为test的文件夹）。创建一个名为images的文件夹，其中保存了上传的文件。
创建功能从图库中选择文件
private void showFileChooser（）{
Intent intent = new Intent（Intent.ACTION_GET_CONTENT）;
intent.setType（application / *）;
intent.addCategory（Intent.CATEGORY_OPENABLE）;
尝试{
startActivityForResult（
Intent.createChooser（intent，Select a File to Upload），
1）;
catch（android.content.ActivityNotFoundException ex）{
Toast.makeText（getActivity（），请安装一个文件管理器。，
Toast.LENGTH_SHORT）.show（）;
$ / code $ / $ p
里面的onActivityResult函数
@Override
public void onActivityResult（int requestCode，int resultCode，Intent data）{
// TODO自动生成的方法存根
super.onActivityResult（requestCode，resultCode，data）;
if（requestCode == 1）{
if（resultCode == Activity.RESULT_OK）{
Uri selectedFileURI = data.getData（）;
File file = new File（selectedFileURI.getPath（）。toString（））;
Log.d（，File：+ file.getName（））;
uploadedFileName = file.getName（）。toString（）;
tokens = new StringTokenizer（uploadedFileName，：）;
first = tokens.nextToken（）;
file_1 = tokens.nextToken（）。trim（）;
txt_file_name_1.setText（file_1）;
$ b这是asyncTask将文件上传到服务器， p>
public class PostDataAsyncTask extends AsyncTask< String，String，String> {
保护void onPreExecute（）{
super.onPreExecute（）;
pDialog = new ProgressDialog（getActivity（））;
pDialog.setCancelable（false）;
pDialog.setMessage（Please wait ...）;
showDialog（）;
$ b $覆盖
保护字符串doInBackground（字符串...字符串）{
尝试{
HttpClient httpClient = new DefaultHttpClient ）;
HttpPost httpPost = new HttpPost（https://10.0.2.2/test/file.php）;
file1 =新建文件（Environment.getExternalStorageDirectory（），
file_1）;
fileBody1 = new FileBody（file1）;
MultipartEntity reqEntity = new MultipartEntity（
HttpMultipartMode.BROWSER_COMPATIBLE）;
reqEntity.addPart（file1，fileBody1）;
httpPost.setEntity（reqEntity）;
HttpResponse response = httpClient.execute（httpPost）;
HttpEntity resEntity = response.getEntity（）;
if（resEntity！= null）{
final String responseStr = EntityUtils.toString（resEntity）
.trim（）;
Log.v（TAG，Response：+ responseStr）;
$ b} catch（NullPointerException e）{
e.printStackTrace（）;
} catch（Exception e）{
e.printStackTrace（）;
}
返回null;
@Override
protected void onPostExecute（String result）{
hideDialog（）;
Log.e（，RESULT：+ result）;
$ b 调用asyncTask on按钮后点击
btn_upload.setOnClickListener（new OnClickListener（）{
@Override
public void onClick（View v）{
PostDataAsyncTask（）。execute（）;
$ b}
}）;
希望这会对您有所帮助。
快乐帮助和快乐编码。
I get stuck at that place and unable to send doc file to php server.
I am using this code.
Here is PHP code.
if($_SERVER['REQUEST_METHOD']=='POST'){
$image = $_POST['image'];
$name = $_POST['name'];
require_once('dbConnect.php');
$sql ="SELECT id FROM volleyupload ORDER BY id ASC";
$res = mysqli_query($con,$sql);
$id = 0;
while($row = mysqli_fetch_array($res)){
$id = $row['id'];
}
$path = "uploads/$id.doc";
$actualpath = "http://10.0.2.2/VolleyUpload/$path";
$sql = "INSERT INTO volleyupload (photo,name) VALUES ('$actualpath','$name')";
if(mysqli_query($con,$sql)){
file_put_contents($path,base64_decode($image));
echo "Successfully Uploaded";
}
mysqli_close($con);
}else{
echo "Error";
}
Here is Java code
private void showFileChooser() {
Intent intent = new Intent();
intent.setType("file/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),
PICK_IMAGE_REQUEST);
}
I called asynTask on upload button.
if (v == buttonUpload) {
// uploadImage();
new PostDataAsyncTask().execute();
}
A function calls in doInBackground is
private void postFile() {
try {
// the file to be posted
String textFile = Environment.getExternalStorageDirectory()
+ "/Woodenstreet Doc.doc";
Log.v(TAG, "textFile: " + textFile);
// the URL where the file will be posted
String postReceiverUrl = "http://10.0.2.2/VolleyUpload/upload.php";
Log.v(TAG, "postURL: " + postReceiverUrl);
// new HttpClient
HttpClient httpClient = new DefaultHttpClient();
// post header
HttpPost httpPost = new HttpPost(postReceiverUrl);
File file = new File(filePath.toString());
FileBody fileBody = new FileBody(file);
MultipartEntity reqEntity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("file", fileBody);
httpPost.setEntity(reqEntity);
// execute HTTP post request
HttpResponse response = httpClient.execute(httpPost);
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
String responseStr = EntityUtils.toString(resEntity).trim();
Log.v(TAG, "Response: " + responseStr);
// you can add an if statement here and do other actions based
// on the response
}
} catch (NullPointerException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
The exception I get is that
java.io.FileNotFoundException: content:/com.topnet999.android.filemanager/storage/0F02-250A/test.doc: open failed: ENOENT (No such file or directory)
There is file in emulator - test.doc.
Is there is any thing I miss in code, please help me.
Or suggest a tutorial to upload pdf to php server.
Thanks In Advance.
解决方案 Here is the solution of my question: -
Here is code of php file - file.php
<?php
// DISPLAY FILE INFORMATION JUST TO CHECK IF FILE OR IMAGE EXIST
echo '<pre>';
print_r($_FILES);
echo '</pre>';
// DISPLAY POST DATA JUST TO CHECK IF THE STRING DATA EXIST
echo '<pre>';
print_r($_POST);
echo '</pre>';
$file_path = "images/";
$file_path = $file_path . basename( $_FILES['file']['name']);
if(move_uploaded_file($_FILES['file']['tmp_name'], $file_path)) {
echo "file saved success";
} else{
echo "failed to save file";
}?>
Put this file in htdoc folder of Xampp inside test named folder (if there is test folder already then ok, otherwise make a folder named "test"). And also create a folder named "images", in which uploaded file was saved.
Create function to select file from gallery
private void showFileChooser() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("application/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
try {
startActivityForResult(
Intent.createChooser(intent, "Select a File to Upload"),
1);
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(getActivity(), "Please install a File Manager.",
Toast.LENGTH_SHORT).show();
}
}
Inside onActivityResult function
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1) {
if (resultCode == Activity.RESULT_OK) {
Uri selectedFileURI = data.getData();
File file = new File(selectedFileURI.getPath().toString());
Log.d("", "File : " + file.getName());
uploadedFileName = file.getName().toString();
tokens = new StringTokenizer(uploadedFileName, ":");
first = tokens.nextToken();
file_1 = tokens.nextToken().trim();
txt_file_name_1.setText(file_1);
}
}
This is asyncTask to upload file to server,
public class PostDataAsyncTask extends AsyncTask<String, String, String> {
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(getActivity());
pDialog.setCancelable(false);
pDialog.setMessage("Please wait ...");
showDialog();
}
@Override
protected String doInBackground(String... strings) {
try {
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("https://10.0.2.2/test/file.php");
file1 = new File(Environment.getExternalStorageDirectory(),
file_1);
fileBody1 = new FileBody(file1);
MultipartEntity reqEntity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("file1", fileBody1);
httpPost.setEntity(reqEntity);
HttpResponse response = httpClient.execute(httpPost);
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
final String responseStr = EntityUtils.toString(resEntity)
.trim();
Log.v(TAG, "Response: " + responseStr);
}
} catch (NullPointerException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(String result) {
hideDialog();
Log.e("", "RESULT : " + result);
}
}
Call the asyncTask on button click after selecting the file from gallery.
btn_upload.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
new PostDataAsyncTask().execute();
}
});
Hope this will help you.
Happy To Help and Happy Coding.
