大于 2 MB 的文件不会上传到服务器

Question

在我的应用程序中，我需要实现上传图像、文本文件、zip 文件夹和 Pdf 文件。 img\txt\zip\pdf 一切都很好，但是当我选择一个大于 2 mb 的文件时，它不会上传。以下是我的代码。

public int uploadFile(String sourceFileUri) 
{
    try
    {
        StrictMode.ThreadPolicy policy= new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);

        String fileName = sourceFileUri;
        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()) 
        {
            title=filename+"";
            generateNotification(title, "Upload Failed..File Not Found");
        }
        else
        {
            FileInputStream fileInputStream = new FileInputStream(sourceFile);
            String upLoadServerUri = "http://xx.xx.xx.xxx:xx/phpwebservice/upload.php";
            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("uploaded_file", filename); 

            dos = new DataOutputStream(conn.getOutputStream());

            dos.writeBytes(twoHyphens + boundary + lineEnd); 
            dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""+ filename + "\"" + 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)
            {
                status = true;
            }
            else
            {
                title=filename+"";
                generateNotification(title, "File Not Uploaded");
            }

            //close the streams //
            fileInputStream.close();
            dos.flush();
            dos.close();
        }
    }
    catch (final MalformedURLException ext) 
    {
        title=filename+"";
        generateNotification(title, "File Not Uploaded");           
    }
    catch (final Exception etx) 
    {
        title=filename+"";
        generateNotification(title, "File Not Uploaded");
    }
    //dialog.dismiss();
    return serverResponseCode;
}

请提供解决方案：

如何使用此方法上传大于 2Mb 的文件？

我的PHP端网络服务代码是：

<?php
     $file_path = "a/";
     $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";
    }
?>

Answer 1

我通过更新 php.ini 得到了与尺寸相关的问题的答案，它对我有用我在 php.ini 的两个地方

进行了更改

upload_max_filesize = 4M
post_max_size = 0

更改此设置后，我的 pdf 文件也得到保存

大于 2 MB 的文件不会上传到服务器

Files which are greater than 2 MB in size are not uploading on server
