如何使用Volley实现分块/表单数据上传

dependencies {
    implementation 'com.android.volley:volley:1.2.1'
}

RequestQueue queue = Volley.newRequestQueue(context);

public void uploadFile(File file) {
    int chunkSize = 1024 * 1024; // 1MB
    int numOfChunks = (int) Math.ceil((double) file.length() / chunkSize);

    for (int i = 0; i < numOfChunks; i++) {
        long start = i * chunkSize;
        long end = Math.min(file.length(), start + chunkSize);
        byte[] chunk = readChunk(file, start, end);

        String url = "YOUR_UPLOAD_ENDPOINT";
        Map<String, String> params = new HashMap<>();
        params.put("chunkNumber", String.valueOf(i));
        params.put("totalChunks", String.valueOf(numOfChunks));
        params.put("fileName", file.getName());

        UploadRequest request = new UploadRequest(Request.Method.POST, url, params, chunk,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    // Handle successful response
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    // Handle error
                }
            });

        queue.add(request);
    }
}

private byte[] readChunk(File file, long start, long end) {
    try {
        RandomAccessFile raf = new RandomAccessFile(file, "r");
        raf.seek(start);
        byte[] buffer = new byte[(int) (end - start)];
        raf.readFully(buffer);
        raf.close();
        return buffer;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}
