fetch 报错排查 SocketError other side closed

fetch 报错

常规

排查 SocketError other side closed

在main.js中使用了fetch，但是在运行main.js的时候时候fetch报错。

% node main.js
 
(node:51258) Warning: Setting the NODE_TLS_REJECT_UNAUTHORIZED environment variable to '0' makes TLS connections and HTTPS requests insecure by disabling certificate verification.  
(Use `node --trace-warnings ...` to show where the warning was created)  
node:internal/deps/undici/undici:11730  
    Error.captureStackTrace(err, this);  
          ^
 
TypeError: fetch failed  
    at Object.fetch (node:internal/deps/undici/undici:11730:11)  
    at async getFansNum (/Users/kazoottt/GitHub/bilibili-fans/main.js:11:20) {  
  cause: SocketError: other side closed  
      at TLSSocket.onSocketEnd (node:internal/deps/undici/undici:8280:26)  
      at TLSSocket.emit (node:events:526:35)  
      at endReadableNT (node:internal/streams/readable:1589:12)  
      at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {  
    code: 'UND_ERR_SOCKET',  
    socket: {  
      localAddress: '198.19.0.1',  
      localPort: 55306,   
      remoteAddress: '198.18.2.185',  
      remotePort: 443,  
      remoteFamily: 'IPv4',  
      timeout: undefined,  
      bytesWritten: 607,  
      bytesRead: 0  
    }  
  }  
}
 
Node.js v20.10.0  

从报错信息中可以看出来是getFansNum这个方法中的fetch方法报了错。

解决方法：

关闭MitM
