[英]How to upload PDF file to server using PHP in Android?
我正在嘗試使用Android中的PHP將PDF文件上傳到服務器。 為此,我獲得了所選文件的URI,並將這些數據發布到服務器中的PHP文件中。 這是我發布該數據的位置:
URL url = new URL(url_path);
conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setDoInput(true);
conn.setChunkedStreamingMode(1024);
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("Content-Type", "multipart/form-data");
OutputStream outputStream = conn.getOutputStream();
InputStream inputStream = c.getContentResolver().openInputStream(path);
Log.e("URI",path.toString());
int bytesAvailable = inputStream.available();
int bufferSize = Math.min(bytesAvailable, maxBufferSize);
byte[] buffer = new byte[bufferSize];
int bytesRead;
while ((bytesRead = inputStream.read(buffer, 0, bufferSize)) != -1) {
outputStream.write(buffer, 0, bytesRead);
}
Log.e("URI",String.valueOf(bytesAvailable));
outputStream.flush();
inputStream.close();
此數據將發布到此php文件:
<?php
print_r($_REQUEST);
$file_name = date("U").".pdf";
$server_path = "uploads/";
$web_path = "http://mysite/uploads/";
$file = $server_path.$file_name;
file_put_contents($file,"");
$fp = fopen("php://input",'r');
echo 'fp : '.$fp;
while ($buffer = fread($fp,8192)){
echo $buffer;
file_put_contents($file,$buffer,FILE_APPEND | LOCK_EX);
}?>
對於每次上載,它都會在我的上載目錄中創建一個新文件。 但是PDF的大小為0字節。 我不知道為什么。 請幫我。 提前致謝。
<?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";
}
?>

除了自己做之外,您還可以輕松使用這個名為ION的庫: https : //github.com/koush/ion 。 上載pdf文件非常簡單:
Ion.with(getContext())
.load("your url")
.setMultipartFile("archive", "application/pdf", new File("path to file"))
.setCallback(...)
最好的方法是改用Retrofit。 這是您可以使用的示例應用程序: https : //github.com/hidrodixtion/Example-Retrofit-Image-Upload
