web3.js日志监控报错：Provider started to reconnect before the response got received!

本文关键字: reconnect, web3, web3.js

当遇到网络不稳定的时候，会偶发出现这个报错，有时候会重连上，但是有时候就直接在这个报错这里卡住。解决办法是把options参数补齐优化。 见如下官方示例代码

// ==========
// Websockets
// ==========

var Web3WsProvider = require('web3-providers-ws');

var options = {
    timeout: 30000, // ms

    // Useful for credentialed urls, e.g: ws://username:password@localhost:8546
    headers: {
      authorization: 'Basic username:password'
    },

    clientConfig: {
      // Useful if requests are large
      maxReceivedFrameSize: 100000000,   // bytes - default: 1MiB
      maxReceivedMessageSize: 100000000, // bytes - default: 8MiB

      // Useful to keep a connection alive
      keepalive: true,
      keepaliveInterval: 60000 // ms
    },

    // Enable auto reconnection
    reconnect: {
        auto: true,
        delay: 5000, // ms
        maxAttempts: 5,
        onTimeout: false
    }
};

var ws = new Web3WsProvider('ws://localhost:8546', options);
