文件不会从Android的上传到PHP服务器 [英] file is not uploading from android to php server

问题描述

您好我写了一个code，如下图所示从我的Andr​​oid手机上传文件PHP服务器。在应用程序运行而没有任何错误，但该文件没有上传到服务器。我去哪儿了？

// upload.php的

  $ target_path =htt​​p://mpss.csce.uark.edu/~smandava/files/;
$ target_path = $ target_path。基本名（$ _FILES ['UploadedFile的'] ['名']）;
如果（move_uploaded_file（$ _ FILES ['UploadedFile的'] ['tmp_name的值']，$ target_path））{
 回声文件。基本名（$ _FILES ['UploadedFile的'] ['名']）。
 已上传;
}其他{
 回声发生错误上传文件，请重试！
}
 

解决方案

在$ target_path应该是一个文件系统路径，而不是一个网站的网址。

  $ target_path ='/家庭/ smandava /的public_html /文件/'; //这样的事情
 

Hi I wrote a code as shown below for uploading file from my android phone to php server. The application is running without any error, but the file is not uploaded to the server. Where did I go wrong ?

public class upload extends Activity {

HttpURLConnection connection = null;
DataOutputStream outputStream = null;
DataInputStream inputStream = null;

String pathToOurFile = "sdcard/Android/data/file.pdf";
String urlServer = "http://mpss.csce.uark.edu/~smandava/upload.php";
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary =  "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);



    try
    {
    FileInputStream fileInputStream = new FileInputStream(new File(pathToOurFile) );

    URL url = new URL(urlServer);
    connection = (HttpURLConnection) url.openConnection();

    // Allow Inputs & Outputs
    connection.setDoInput(true);
    connection.setDoOutput(true);
    connection.setUseCaches(false);

    // Enable POST method
    connection.setRequestMethod("POST");

    connection.setRequestProperty("Connection", "Keep-Alive");
    connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);

    outputStream = new DataOutputStream( connection.getOutputStream() );
    outputStream.writeBytes(twoHyphens + boundary + lineEnd);
    outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile +"\"" + lineEnd);
    outputStream.writeBytes(lineEnd);

    bytesAvailable = fileInputStream.available();
    bufferSize = Math.min(bytesAvailable, maxBufferSize);
    buffer = new byte[bufferSize];

    // Read file
    bytesRead = fileInputStream.read(buffer, 0, bufferSize);

    while (bytesRead > 0)
    {
    outputStream.write(buffer, 0, bufferSize);
    bytesAvailable = fileInputStream.available();
    bufferSize = Math.min(bytesAvailable, maxBufferSize);
    bytesRead = fileInputStream.read(buffer, 0, bufferSize);
    }

    outputStream.writeBytes(lineEnd);
    outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

    // Responses from the server (code and message)
    int serverResponseCode = connection.getResponseCode();
    String serverResponseMessage = connection.getResponseMessage();

    fileInputStream.close();
    outputStream.flush();
    outputStream.close();
    }
    catch (Exception ex)
    {
    //Exception handling
    }


}

}

//upload.php

$target_path = "http://mpss.csce.uark.edu/~smandava/files/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
 echo "The file ".  basename( $_FILES['uploadedfile']['name']).
 " has been uploaded";
} else{
 echo "There was an error uploading the file, please try again!";
}

解决方案

The $target_path should be a file system path, not a web url.

$target_path = '/home/smandava/public_html/files/'; // something like this
