我正在尝试从 java 程序上传和重命名文件。
我的java上传方法:
public void bestandUploaden(String oudeUrl, String nieuweNaam) throws ParseException, IOException {
System.out.println("oude url: " + oudeUrl);
System.out.println("nieuwe naam: " + nieuweNaam);
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("**Website url**/upload_file.php");
File file = new File(oudeUrl);
MultipartEntity mpEntity = new MultipartEntity();
mpEntity.addPart("file", new FileBody(file));
mpEntity.addPart("uniekeNaam", new StringBody(nieuweNaam));
httppost.setEntity(mpEntity);
System.out.println("executing request " + httppost.getRequestLine());
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
System.out.println(response.getStatusLine());
if (resEntity != null) {
System.out.println(EntityUtils.toString(resEntity));
}
if (resEntity != null) {
resEntity.consumeContent();
}
httpclient.getConnectionManager().shutdown();
}
我的PHP代码:
<?php
echo "Nieuwe bestandsnaam :" . $_FILES["uniekeNaam"];
$disallowedExts = array("exe");
$extension = end(explode(".", $_FILES["file"]["name"]));
if (!in_array($extension, $disallowedExts))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br>";
echo "Type: " . $_FILES["file"]["type"] . "<br>";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";
if (file_exists("documenten/" . $_FILES["uniekeNaam"]))
{
echo $_FILES["uniekeNaam"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"documenten/" . $_FILES["uniekeNaam"]);
echo "Stored in: " . "documenten/" . $_FILES["uniekeNaam"];
}
}
}
else
{
echo "Invalid file";
}
?>
我的 java 控制台输出:
oude url: D:\Dropbox\Documents\youtube.txt
nieuwe naam: Een_textbestand.txt
executing request POST **Website url**/upload_file.php HTTP/1.1
HTTP/1.1 200 OK
Nieuwe bestandsnaam :Upload: youtube.txt<br>Type: application/octet-stream<br>Size: 1.8095703125 kB<br>Temp file: /tmp/phpp9igba<br> already exists.
如您所见,'uniekeNaam' 没有从我的 java 转移到我的 php 部分。它是空的。我没有任何 php 知识并尝试了不同的方法,但似乎没有任何效果。我只想能够浏览到我的 java 程序中的文件并将该文件上传到网络服务器并重命名它。如果我不进行重命名,它会起作用,所以我想我只需要弄清楚如何将“uniekeNaam”从 java 转移到 php。
如果我做:
print_r($_FILES);
我得到:
Array (
[file] => Array (
[name] => motoplus.pdf
[type] => application/octet-stream
[tmp_name] => /tmp/php0V4SCS
[error] => 0 [size] => 1010671
)
)
