Hyperlane file chunked upload server: easy to upload large files
In modern web applications, file upload is a core function, especially for large files. Traditional upload methods often fail due to network interruption or timeout. To address this pain point, we launched theHyperlaneThe file uploading server code in chunks provides developers with an efficient and reliable solution for large file uploads. Whether you are building a cloud storage service, a video platform or an online education system, this tool can perfectly meet your needs!
Why choose Hyperlane file upload in chunks?
1. Upload in blocks to easily deal with large files
By splitting large files into small blocks to upload, the Hyperlane file chunked upload server not only avoids upload failures caused by network fluctuations, but also supports breakpoint continuous transmission. Even if the network is interrupted, users can continue to upload from the breakpoint, greatly improving the user experience.
2. Simple and easy-to-use development experience
based onHyperlaneLightweight HTTP server library, this code is clear and logical. Developers can implement file chunked upload function with just a few lines of code, and can also easily expand and customize according to their needs.
3. High performance and security coexist
Hyperlane byRustLanguage-driven, inheriting Rust's outstanding performance and memory security features. Whether it is high concurrent requests or long-term running, your server can remain stable and efficient.
4. Complete documentation and active community
Hyperlane provides detailed API documentation and active community support. Whether you are a Rust newbie or a veteran developer, get started quickly and get technical help.
5. A wide range of application scenarios
From cloud storage to video streaming to enterprise-level file management systems, Hyperlane file chunk uploads are suitable for any scenario where large files are processed efficiently.
Feature Highlights
- Block management: Pass the file ID, block index, total number of blocks and file name through the request header to ensure that the upload process is orderly.
- Temporary storage and merge: Each file block is saved to a temporary directory and is automatically merged into a complete file after uploading, saving development time.
- Error handling: Complete abnormality detection mechanism to ensure that any problems during the upload process can be promptly reported.
Start quickly
In just a few steps, you can integrate Hyperlane file uploads into your project:
1. Install Hyperlane
Run the following command in your Rust project:
cargo add hyperlane
2. Add server code
Copy the file upload code we provide in chunks to your project. Here is the core code snippet:
use hyperlane::*;
use std::fs;
use std::path::Path;
const UPLOAD_DIR: &str = "uploads";
pub async fn handle(ctx: Context) {
if !Path::new(UPLOAD_DIR).exists() {
let _ = fs::create_dir_all(UPLOAD_DIR);
}
// Process file block upload logic...}3. Custom configuration
Adjust the upload directory according to your needs (e.g.uploads), log settings or block size, flexible to adapt to different scenarios.
4. Start the service
Run your server program to start receiving file chunked upload requests.
Sample code
Here is some of the key logic that shows how to process file blocks and merge complete files:
// Get file information from the request headerlet file_id = ctx.get_request_header("x-file-id").await.unwrap_or_default();
let chunk_index = ctx.get_request_header("x-chunk-index").await.unwrap_or_default().parse::<usize>().unwrap_or(0);
let total_chunks = ctx.get_request_header("x-total-chunks").await.unwrap_or_default().parse::<usize>().unwrap_or(0);
let file_name = ctx.get_request_header("x-file-name").await.unwrap_or_default();
// Save file blockslet chunk_path = format!("{}/{}_{}", UPLOAD_DIR, file_id, chunk_index);
fs::write(&chunk_path, ctx.get_request_body().await).unwrap();
// Merge filesif all_chunks_uploaded {
let final_path = format!("{}/{}", UPLOAD_DIR, file_name);
let mut output_file = fs::File::create(&final_path).unwrap();
for i in 0..total_chunks {
let chunk_path = format!("{}/{}_{}", UPLOAD_DIR, file_id, i);
let data = fs::read(&chunk_path).unwrap();
output_file.write_all(&data).unwrap();
fs::remove_file(&chunk_path).unwrap();
}
