FileUpload 如何取代 Android 檔案上傳中已棄用的 org.apache.http.entity.FileEntity？

利用FileUpload 取代已棄用的org.apache.http.entity.FileEntity

Android 6 中已棄用org.apache. http需要探索文件上傳的替代方法。雖然 HttpURLConnection 提供了一種解決方法，但其複雜性可能令人望而生畏。

更有效的解決方案是利用 FileUpload 類，如以下程式碼片段所示：

// Instantiate the HttpURLConnection
URL url = new URL(server_url);
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();

// Set connection properties
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setDoOutput(true);

// Create a FileUpload instance
String boundary = UUID.randomUUID().toString();
FileUpload fileUpload = new FileUpload();

// Add file to FileUpload
FileInputStream fileInputStream = new FileInputStream(file);
fileUpload.addFilePart("image", file.getName(), fileInputStream, "image/png");

// Set connection headers
httpURLConnection.addRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);

// Write to connection
fileUpload.write(httpURLConnection.getOutputStream());

// Read response
if (httpURLConnection.getResponseCode() == HttpURLConnection.HTTP_OK) {
    // Process response
}
else {
    // Handle errors
}

// Close connection
httpURLConnection.disconnect();

透過使用 FileUpload，您可以簡化檔案上傳過程，而不會過於複雜。
