我正在尝试将应用中生成的文本文件上传到服务器。 当尝试获取服务器响应时,我会抛出异常EOF。
赞赏任何输入
我的创建文件代码:
File sdCard = android.os.Environment.getExternalStorageDirectory();
File theDirectory = new File(sdCard.getAbsolutePath());
theFile = new File(theDirectory, "userdetails.txt");
theDirectory.getParentFile().mkdirs();
//file.createNewFile();
FileOutputStream fOut = new FileOutputStream(theFile);
OutputStreamWriter out = new OutputStreamWriter(fOut);
out.append(username+"\n");
out.append(email+"\n");
out.append(password+"\n");
out.close();
... uploadFileName = theFile.toString(); uploadFile(uploadFileName);
上传方法:
String fileName = sourceFileUri;
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :" + uploadFileName);
runOnUiThread(new Runnable() {
public void run() {
Log.d("REGISTRATION PAGE", "Source File not exist :" + uploadFileName);
}
});
return 0;
}
else
{
try {
// open a URL connection to the Servlet
FileInputStream fileInputStream = new FileInputStream(sourceFile);
URL url = new URL(upLoadServerUri);
// Open a HTTP connection to the URL
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "close");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("uploaded_file", fileName);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename="
+ fileName + "" + lineEnd);
dos.writeBytes(lineEnd);
// create a buffer of maximum size
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// Responses from the server (code and message)
serverResponseCode = conn.getResponseCode();
String serverResponseMessage = conn.getResponseMessage();
Log.d("uploadFile", "HTTP Response is : "
+ serverResponseMessage + ": " + serverResponseCode);
if(serverResponseCode == 200){
runOnUiThread(new Runnable() {
public void run() {
String msg = "File Upload Completed.\n\n See uploaded file here : \n\n"
+" http://www.androidexample.com/media/uploads/"
+uploadFileName;
//messageText.setText(msg);
Toast.makeText(RegisterActivity.this, "File Upload Complete.", Toast.LENGTH_SHORT).show();
}
});
}
//close the streams //
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
dialog.dismiss();
ex.printStackTrace();
runOnUiThread(new Runnable() {
public void run() {
// messageText.setText("MalformedURLException Exception : check script url.");
Toast.makeText(RegisterActivity.this, "MalformedURLException",
Toast.LENGTH_SHORT).show();
}
});
Log.e("Upload file to server", "error: " + ex.getMessage(), ex);
} catch (Exception e) {
dialog.dismiss();
e.printStackTrace();
runOnUiThread(new Runnable() {
public void run() {
// messageText.setText("Got Exception : see logcat ");
Toast.makeText(RegisterActivity.this, "Got Exception : see logcat ",
Toast.LENGTH_SHORT).show();
}
});
Log.e("Upload file to server Exception", "Exception : "
+ e.getMessage(), e);
}
dialog.dismiss();
return serverResponseCode;
我在服务器上的php脚本:
<?php
$file_path = "uploads/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>
更新: 在这里更改了DataOutPutStrem args(我在世界上有一个\):
dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\"" + fileName + "\"" + lineEnd);
这给了一个服务器
response = OK and respoonseCode = 200;
但是我看到服务器目录中没有新文件! Ive将新文件所在的目录记录为URL + filePath
www.mooneycallans /圆形大厅//存储/模拟/ 0 / userdetails.txt
但是这不应该是:
www.mooneycallans /圆形大厅/ userdetails.txt
... as userdetails.txt是我在应用程序中创建的文件的名称。
答案 0 :(得分:0)
哎哟。我的PHP脚本是罪魁祸首,我的路径为:
$file_path = "uploads";
而不是:
$file_path = "uploads/";
一天半后但它有效:)
