PHP Server文件上传中的代码，我是通过块完成文件上传的，请谁帮我发送正确的代码文件通过块上传和相关的android文件上传代码
<?php
if (empty($_FILES) || $_FILES['file']['error']) {
die('{"OK": 0, "info": "Failed to move uploaded file."}');
}
$chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0;
$chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 0;
$fileName = isset($_REQUEST["name"]) ? $_REQUEST["name"] : $_FILES["file"]["name"];
$filePath = "uploads/$fileName";
// Open temp file
$out = @fopen("{$filePath}.part", $chunk == 0 ? "wb" : "ab");
//$out2 = @fopen("{$filePath}.part2", $chunk == 0 ? "wb" : "ab");
if ($out) {
// Read binary input stream and append it to temp file
$in = @fopen($_FILES['file']['tmp_name'], "rb");
if ($in) {
while ($buff = fread($in, 4096))
fwrite($out, $buff);
//print($out);
// echo sizeof($out);
} else
die('{"OK": 0, "info": "Failed to open input stream."}');
@fclose($in);
@fclose($out);
@unlink($_FILES['file']['tmp_name']);
} else
die('{"OK": 0, "info": "Failed to open output stream."}');
// Check if file has been uploaded
if (!$chunks || $chunk == $chunks - 1)
{
// Strip the temp .part suffix off
rename("{$filePath}.part", $filePath);
}
die('{"OK": 1, "info": "Upload successful."}');?>

如果您使用的是免费托管，则页面会被重定向以跟踪编号。点击量。您可能会收到Http响应：200 OK，但您不会看到文件上传，因为文件丢失了。
我自己花了3天时间寻找解决方案，但一无所获。我自己发现的。

试试这个：它 100% 工作副本。
上传函数：（函数的参数是图像路径）
public void uploadFile(String sourceFileUri) {
String fileName = imagePath;
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(imagePath);
if (!sourceFile.isFile()) {
if (dialog != null && dialog.isShowing()) {
dialog.dismiss();
}
Log.e("uploadFile", "Source File not exist :"+imagePath);

try {

菲律宾语服务：
$file_path = "images/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{ echo "fail";}
必须在服务器中创建名为“images”的文件夹，以便$file_path有效

我不知道您的代码，但为您提供两个工作代码：这适用于所有类型的文件。我将其用于图像、音频和视频文件。
Android系统:
new UploadFileAsync().execute("");
private class UploadFileAsync extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... params) {
try {
String sourceFileUri = "/mnt/sdcard/abc.png";
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()) {
try {
String upLoadServerUri = "http://website.com/abc.php?";
// 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.setRequestProperty("ENCTYPE",
"multipart/form-data");

"multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("bill", sourceFileUri);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"bill\";filename=\""
+ sourceFileUri + "\"" + 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);
