RPC service based on ThinkPHP6 and Swoole implements breakpoint resume function

The RPC service based on ThinkPHP6 and Swoole realizes the resumable transfer function

In the current network environment, file transfer has always been something we often need to deal with, but In the process of file transfer, we often face problems such as excessive file size and unstable network. In order to solve these problems, we can consider using the breakpoint resume function, that is, when the file transfer is interrupted, the transfer can be continued from the breakpoint without retransmitting the entire file.

This article will introduce how to implement the breakpoint resume function based on ThinkPHP6 and Swoole's RPC service, and provide specific code examples.

  1. Building the environment
    Before starting, you need to ensure that PHP, ThinkPHP6 framework and Swoole extension have been installed locally. You can use composer to install related dependency packages, for example:

    composer require topthink/think-swoole
    Copy after login
  2. Create RPC service
    First, we need to create an RPC service to handle file transfer-related requests. In ThinkPHP6, you can use the Swoole extension to implement RPC services. First, execute the following command in the root directory of the project to create an RPC service file:

    php think swoole:rpcserver MyServer
    Copy after login

After executing the above command, a file named MyServer will be generated in the app/swoole/ directory. php file, this file is our RPC service.

  1. Implementing the breakpoint resume function
    Next, we need to implement the breakpoint resume function in the MyServer.php file. First, define a method for handling file uploads, such as uploadFile:

    public function uploadFile($data)
    {
     // 获取上传的文件
     $file = $data['file'];
    
     // 获取上传的文件信息
     $filename = $file['name'];
     $filetemp = $file['tmp_name'];
    
     // 文件保存路径
     $savepath = '/path/to/save/' . $filename;
    
     // 判断文件是否已经存在
     if (file_exists($savepath)) {
         // 获取已上传的文件大小
         $uploadedSize = filesize($savepath);
    
         // 继续上传文件
         $handle = fopen($filetemp, 'rb');
         fseek($handle, $uploadedSize);
         $contents = fread($handle, 1024);
         fclose($handle);
    
         file_put_contents($savepath, $contents, FILE_APPEND);
    
         return true;
     } else {
         // 直接保存文件
         move_uploaded_file($filetemp, $savepath);
    
         return true;
     }
    }
    Copy after login
  2. Configure routing and start the RPC service
    Next, we need to configure routing to upload file requests Route to the uploadFile method of the RPC service. Add the following configuration in the config/route.php file:

    use thinkacadeRoute;
    
    Route::post('upload', 'ppswooleMyServer@uploadFile');
    Copy after login

Finally, start the RPC service in the onWorkerStart method in the MyServer.php file:

public function onWorkerStart(SwooleServer $server, int $workerId)
{
    // 启动RPC服务
    $rpcServer = new     hinkswooleRpcServer($server);
    $rpcServer->setHandler('ppswooleMyServer');
    $rpcServer->start();
}
Copy after login
  1. Client call
    After completing the above steps, you can call the uploadFile method of the RPC service on the client to implement the breakpoint resume function. It can be implemented using the curl command or a function that encapsulates an uploaded file.

For example, use the curl command on the client to upload files:

curl -F file=@/path/to/file/upload http://127.0.0.1:8000/upload
Copy after login
  1. Summary
    This article introduces how to implement breakpoint resume upload based on the RPC service of ThinkPHP6 and Swoole Function. By using the Swoole extension to implement RPC services, combined with the routing and controller functions of ThinkPHP6, we can easily implement the breakpoint resume function and improve the efficiency and stability of file transfer.

Through the above steps, you can easily build an upload service that supports the resume function. The code example also provides a basic implementation that you can modify and extend according to your actual needs. Wishing you better results with your file transfers!
