我正在尝试将文件从我的Android设备上传到php服务器，但服务器未收到任何文件。这是我的示例代码，我在线找到了。php服务器，我正在通过块上传文件

PHP Server代码在文件上传中，我已经完成了通过块进行文件上传，请有人帮助我通过块和相关的android文件上传代码发送正确的代码文件
<?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 ?

我不知道您的代码，但是为您提供了两个有效的代码：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：
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.setUseCaches(false); // Don't use a Cached Copy conn.setRequestMethod("POST"); conn.setRequestProperty("Connection", "Keep-Alive"); conn.setRequestProperty("ENCTYPE", "multipart/form-data"); conn.setRequestProperty("Content-Type", "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); } // 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(); if (serverResponseCode == 200) { // messageText.setText(msg); //Toast.makeText(ctx, "File Upload Complete.", // Toast.LENGTH_SHORT).show(); // recursiveDelete(mDirectory1); } // close the streams // fileInputStream.close(); dos.flush(); dos.close(); } catch (Exception e) { // dialog.dismiss(); e.printStackTrace(); } // dialog.dismiss(); } // End else block } catch (Exception ex) { // dialog.dismiss(); ex.printStackTrace(); } return "Executed"; } @Override protected void onPostExecute(String result) { } @Override protected void onPreExecute() { } @Override protected void onProgressUpdate(Void... values) { } }
PHP ：：
<?php if (is_uploaded_file($_FILES['bill']['tmp_name'])) { $uploads_dir = './'; $tmp_name = $_FILES['bill']['tmp_name']; $pic_name = $_FILES['bill']['name']; move_uploaded_file($tmp_name, $uploads_dir.$pic_name); } else{ echo "File not uploaded successfully."; } ?>
