php - 通过 HttpURLConnection POST Android 将变量传递给 PHP
问题描述
我有使用 HttpURLConnection 上传 pdf 文件的功能,它可以工作并且 pdf 文件已上传,现在我想传递变量 UserID , ProviderId 等,我尝试了这种方式作为下面的代码,但我不知道为什么它不工作, pdf文件已上传,但没有任何内容进入数据库
我添加变量的部分
connection.setRequestProperty("USERID",UserId); //
connection.setRequestProperty("ProviderID",DriverIDFinal);
connection.setRequestProperty("belongto","USER"); //
connection.setRequestProperty("paidstatus","0"); //
connection.setRequestProperty("pdffileurl",PdfUrlServer); //
这是我的代码
public int uploadFile(final String selectedFilePath){
int serverResponseCode = 0;
HttpURLConnection connection;
DataOutputStream dataOutputStream;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead,bytesAvailable,bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File selectedFile = new File(selectedFilePath);
String[] parts = selectedFilePath.split("/");
final String fileName = parts[parts.length-1];
PdfUrlServer = "http://*****/****/pdfrec/"+ fileName;
if (!selectedFile.isFile()){
hideDialog();
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(****.this,"Source File Doesn't Exist",Toast.LENGTH_SHORT).show();
}
});
return 0;
}else{
try{
FileInputStream fileInputStream = new FileInputStream(selectedFile);
URL url = new URL(SERVER_URL);
connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);//Allow Inputs
connection.setDoOutput(true);//Allow Outputs
connection.setUseCaches(false);//Don't use a cached Copy
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("ENCTYPE", "multipart/form-data");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
connection.setRequestProperty("uploaded_file",selectedFilePath);
connection.setRequestProperty("USERID",UserId); // here is where i add the par....
connection.setRequestProperty("ProviderID",DriverIDFinal);
connection.setRequestProperty("belongto","USER"); //
connection.setRequestProperty("paidstatus","0"); //
connection.setRequestProperty("pdffileurl",PdfUrlServer); //
//creating new dataoutputstream
dataOutputStream = new DataOutputStream(connection.getOutputStream());
//writing bytes to data outputstream
dataOutputStream.writeBytes(twoHyphens + boundary + lineEnd);
dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""
+ selectedFilePath + "\"" + lineEnd);
dataOutputStream.writeBytes(lineEnd);
//returns no. of bytes present in fileInputStream
bytesAvailable = fileInputStream.available();
//selecting the buffer size as minimum of available bytes or 1 MB
bufferSize = Math.min(bytesAvailable,maxBufferSize);
//setting the buffer as byte array of size of bufferSize
buffer = new byte[bufferSize];
//reads bytes from FileInputStream(from 0th index of buffer to buffersize)
bytesRead = fileInputStream.read(buffer,0,bufferSize);
//loop repeats till bytesRead = -1, i.e., no bytes are left to read
while (bytesRead > 0){
//write the bytes read from inputstream
dataOutputStream.write(buffer,0,bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable,maxBufferSize);
bytesRead = fileInputStream.read(buffer,0,bufferSize);
}
dataOutputStream.writeBytes(lineEnd);
dataOutputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
serverResponseCode = connection.getResponseCode();
String serverResponseMessage = connection.getResponseMessage();
Log.i("TAG", "Server Response is: " + serverResponseMessage + ": " + serverResponseCode);
//response code of 200 indicates the server status OK
if(serverResponseCode == 200){
runOnUiThread(new Runnable() {
@Override
public void run() {
//add the code after the pdf is uploaded
}
});
}
//closing the input and output streams
fileInputStream.close();
dataOutputStream.flush();
dataOutputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(****.this,"File Not Found",Toast.LENGTH_SHORT).show();
}
});
} catch (MalformedURLException e) {
e.printStackTrace();
Toast.makeText(****.this, "URL error!", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
e.printStackTrace();
Toast.makeText(****.this, "Cannot Read/Write File!", Toast.LENGTH_SHORT).show();
}
hideDialog();
return serverResponseCode;
}
}
这是我的 PHP
<?php
include 'include/DatabaseConfig.php';
// Create connection
$conn = new mysqli($HostName, $HostUser, $HostPass, $DatabaseName);
$file_path = "pdfrec/";
$UserID = $_POST['USERID'];
$ProviderID = $_POST['ProviderID'];
$belongto = $_POST['belongto'];
$paidstatus = $_POST['paidstatus'];
$pdffileurl = $_POST['pdffileurl'];
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path) ){
$InsertSQL = "INSERT INTO **** (userid, providerid, belongto, paidstatus, pdffileurl) VALUES ($UserID,$ProviderID,$belongto,$paidstatus,$pdffileurl)";
if(mysqli_query($conn, $InsertSQL)){
}
mysqli_close($conn);
echo "success";
} else{
echo "fail";
}
?>
解决方案
集setRequestProperty
标题。POST 数据位于请求的正文中。
请参阅有关如何执行此操作的问题:
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("USERID", UserId));
... add others ...
OutputStream os = connection.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(getQuery(params));
writer.flush();
writer.close();
os.close();
