【问题描述】：
嗨，所以我设法将文件从应用程序发送到服务器，但是在我发送到服务器后它将返回 503（文件不存在）。任何人都可以检查我的代码吗
错误：HTTP 响应是：服务暂时不可用：503 如果文件存在，我应该得到 502；如果文件上传，我应该得到 200 OK
这是java函数。
private int upload(String uri_)
{
String fileName = uri_;
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(uri_);
if (!sourceFile.isFile()) {
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :"
+fileName);
return 0;
}
else
{
try {
// open a URL connection to the Servlet
FileInputStream fileInputStream = new FileInputStream(sourceFile);
URL url = new URL(url_);
// Open a HTTP connection to the URL
conn = (HttpURLConnection) url.openConnection();
// Allow Inputs & Outputs
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
// Enable POST method
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary");
dos = new DataOutputStream( conn.getOutputStream() );
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + fileName );
dos.writeBytes(lineEnd);
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.i("uploadFile", "HTTP Response is : "
+ serverResponseMessage + ": " + serverResponseCode);
if(serverResponseCode == 200){
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(PhotoActivity.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() {
Toast.makeText(PhotoActivity.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() {
Toast.makeText(PhotoActivity.this, "Got Exception : see logcat ",
Toast.LENGTH_SHORT).show();
}
});
Log.e("Upload file to server Exception", "Exception : "
+ e.getMessage(), e);
}
dialog.dismiss();
return serverResponseCode;
} // End else block
}
PHP部分
<?php
$tar="./";
$src=$_FILES['uploadedfile']['name'];
$tar=$tar . basename($src);
if(file_exists($src))
{
if(move_uploaded_file($src,$tar))
{
echo "success";
}
else
{header("Server Error",ture,502);}
}
else
{header("Server Error",ture,503);}
?>
【问题讨论】：

请清楚您的问题。
-
php.net/manual/de/function.header.php 标头必须返回布尔值而不是
ture:) 并且不要关闭您的 php 脚本，只需删除?> -
我想将图像从手机存储上传到服务器，但它从未上传。我使用 header 来跟踪文件语句，似乎 php 无法识别我的图像文件。问题是我做错了什么，所以服务器无法从 android 应用程序接收我的图像！？

嗨，A.S.我按照你的建议还是不行:(
