FileUpload 如何替换 Android 文件上传中已弃用的 org.apache.http.entity.FileEntity？

利用 FileUpload 替换已弃用的 org.apache.http.entity.FileEntity

Android 6 中已弃用 org.apache.http需要探索文件上传的替代方法。虽然 HttpURLConnection 提供了一种解决方法，但其复杂性可能令人望而生畏。

更有效的解决方案是利用 FileUpload 类，如以下代码片段所示：

// 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();

通过使用 FileUpload，您可以简化文件上传过程，而不会过于复杂。
