[英]Uploading file from android (java) to server using PHP
Hello Im trying to upload files from my android application to my server using PHP. 您好我试图使用PHP将文件从我的Android应用程序上传到我的服务器。
I have read this posts: 我看过这篇文章:
How to upload a file using Java HttpClient library working with PHP http://www.veereshr.com/Java/Upload How do I send a file in Android from a mobile device to server using http? 如何使用与PHP一起使用的Java HttpClient库上传文件 http://www.veereshr.com/Java/Upload 如何使用http将Android中的文件从移动设备发送到服务器?
This is my JAVA code: 这是我的JAVA代码:
public void upload() throws Exception {
File file = new File("data/data/com.tigo/databases/exercise");
Log.i("file.getName()", file.getName());
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://***.***.***.***/backDatabase.php");
InputStreamEntity reqEntity = new InputStreamEntity( new FileInputStream(file), -1);
reqEntity.setContentType("binary/octet-stream");
reqEntity.setChunked(true);
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
if((response.getStatusLine().toString()).equals("HTTP/1.1 200 OK")){
// Successfully Uploaded
Log.i("uploaded", response.getStatusLine().toString());
}
else{
// Did not upload. Add your logic here. Maybe you want to retry.
Log.i(" not uploaded", response.getStatusLine().toString());
}
httpclient.getConnectionManager().shutdown();
}
This is my PHP code: 这是我的PHP代码:
<?php
$uploads_dir = '/tigo/databaseBackup';
if (is_uploaded_file($_FILES['exercise']['tmp_name']))
{
$info = "File ". $_FILES['exercise']['name'] ." uploaded successfully.\n";
$file = 'emailTest.log';
file_put_contents($file, $info, FILE_APPEND | LOCK_EX);
move_uploaded_file ($_FILES['exercise'] ['tmp_name'], $_FILES['exercise'] ['name']);
}
else
{
$info = "Possible file upload attack: ";
$file = 'emailTest.log';
file_put_contents($file, $info, FILE_APPEND | LOCK_EX);
$info = "filename '". $_FILES['exercise']['tmp_name'] . "'.";
file_put_contents($file, $info, FILE_APPEND | LOCK_EX);
print_r($_FILES);
}
?>
In my logcat i get HTTP/1.1 200 OK. 在我的logcat中,我得到HTTP / 1.1 200 OK。 When i look at the server logs i get this error: 当我查看服务器日志时,我收到此错误:
PHP Notice: Undefined index: exercise in /var/www/backDatabase.php on line 23
I also tried to use: 我也试过用:
$_FILES['userfile']['name']
Instead of 代替
$_FILES['exercise']['tmp_name']
And i got the same error in my server logs. 我在服务器日志中遇到了同样的错误。
I think my problem is that I cant get reference to my uploaded file. 我想我的问题是我无法参考我上传的文件。
Thanks for helping. 谢谢你的帮助。
try multipart entity 尝试多部分实体
public void upload(String filepath) throws IOException
{
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
HttpPost httppost = new HttpPost("url");
File file = new File(filepath);
MultipartEntity mpEntity = new MultipartEntity();
ContentBody cbFile = new FileBody(file, "image/jpeg");
mpEntity.addPart("userfile", cbFile);
httppost.setEntity(mpEntity);
System.out.println("executing request " + httppost.getRequestLine());
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
// check the response and do what is required
}
Try this: 尝试这个:

if (resEntity != null) {
resEntity.consumeContent();
}
httpclient.getConnectionManager().shutdown();
}
}

<?php

You may need to change the paths in order to fit your needs, but the above code works. 您可能需要更改路径以满足您的需求,但上述代码可以正常工作。
This is Just Small Piece of Code. 这只是一小段代码。 it can send any image from Android to your Web Server using Android 它可以使用Android将任何图像从Android发送到您的Web服务器
System.Net.WebClient Client = new System.Net.WebClient();
Client.Headers.Add("Content-Type", "binary/octet-stream");
byte[] result = Client.UploadFile("localhost/FolderName/upload.php", "POST", path);
string s = System.Text.Encoding.UTF8.GetString(result, 0, result.Length);
Here is the PHP Code {upload.php}. 这是PHP代码{upload.php}。 Create a Folder name { Uploads } in your Application. 在您的应用程序中创建文件夹名称{Uploads}。
<?php
$uploads_dir = 'uploads/'; //Directory to save the file that comes from client application.
if ($_FILES["file"]["error"] == UPLOAD_ERR_OK)
{
$tmp_name = $_FILES["file"]["tmp_name"];
$name = $_FILES["file"]["name"];
move_uploaded_file($tmp_name, "$uploads_dir/$name");
}
?>
