我想將 PDF 文件從 android 本機應用程序上傳到服務器。我檢查了服務器配置，一切都很好，比如上傳時間和大小。我在 base64 中轉換 PDF 文件并嘗試發送到服務器。服務器發送 FILE[] 的空白值（檢查下面的響應）。我嘗試了另一種上傳 PDF 的方法，即多部分。這也不起作用。//Multipart code - 1st methodRequestBody requestBody = new MultipartBody.Builder().setType(MultipartBody.FORM).addFormDataPart("file", new File(pdfpath).getName(),RequestBody.create(MediaType.parse("application/pdf"), new File(pdfpath).getName())).addFormDataPart("some-field", "some-value").build();System.out.println("Multipart Data "+requestBody.toString());//---------------------------------------------------------//Base64 code - 2nd methodpublic String converPDFBase64(File mfile) { ByteArrayOutputStream output=null; try { InputStream inputStream = null; inputStream = new FileInputStream(mfile.getAbsolutePath()); byte[] buffer = new byte[8192]; int bytesRead; output = new ByteArrayOutputStream(); Base64OutputStream output64 = new Base64OutputStream(output, Base64.DEFAULT);while ((bytesRead = inputStream.read(buffer)) != -1) { output64.write(buffer, 0, bytesRead); } output64.close(); } catch (IOException e) { e.printStackTrace(); } return output.toString(); }我想使用任何方法將大型 PDF 文件發送到服務器。

我明白了，我正在使用 AQuery，現在我已經改變了它?，F在通過 OkHttpClient 調用服務，它工作正常。
public Message getMessageMedia(File file,String type) {
Message messageObj = new Message();
try {
OkHttpClient client = new OkHttpClient.Builder().connectTimeout(10, TimeUnit.SECONDS).writeTimeout(180, TimeUnit.SECONDS).readTimeout(180, TimeUnit.SECONDS).build();
RequestBody body = new MultipartBody.Builder().setType(MultipartBody.FORM)
.addFormDataPart(RequestParameters.USERID, "" + SharedPreferencesMethod.getUserId(this))
.addFormDataPart(RequestParameters.TO_USERID, "" + user.getUserId())
.addFormDataPart(RequestParameters.MESSAGE_MEDIA,file.getName(),RequestBody.create(MediaType.parse("application/pdf"),file))
.addFormDataPart(RequestParameters.MESSAGE_MEDIA_TYPE, "" + type)
.addFormDataPart(RequestParameters.MESSAGE,"" +"PDF")
.addFormDataPart("msg_identifer", System.currentTimeMillis() + "")
.build();
Request request = new Request.Builder()
.url(API.SEND_MESSAGE)
.post(body)
.build();
System.out.println("Input Data"+request.toString());
client.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(final Call call, final IOException e) {
System.out.println("PDF Faliure "+e.toString());
}
@Override
public void onResponse(final Call call, final Response response) throws IOException {
if (!response.isSuccessful()) {
System.out.println("PDF Response Error "+response.toString());
}else{
System.out.println("PDF Response "+response.toString());
}
}
});
etMessage.setText("PDF");
Date now = Calendar.getInstance().getTime();
SimpleDateFormat dateFormat = new SimpleDateFormat("hh:mm a");
messageObj.setId(REMOVE);
messageObj.setMsg_identifer(System.currentTimeMillis() + "");
messageObj.setMessageMedia(String.valueOf(file));
messageObj.setMessageMediaType(type);
messageObj.setReadStatus("0");
messageObj.setMessageAT("Sending...");
messageObj.setUserId(SharedPreferencesMethod.getUserId(getApplicationContext()));
} catch (Exception ex) {
System.out.println("Media Message Error "+ex);
}
return messageObj;
}
