## 错误解决方案

### 如果连接节点出现这个类似的错误
	cURL error 60: SSL certificate problem: unable to get local issuer certificate (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

	从 https://curl.haxx.se/docs/caextract.html 上下载cacert.pem 下载最新的就行

	放在该目录下G:\phpstudy_pro\Extensions\php\php7.3.4nts\extras\ssl\cacert.pem


	打开php.ini  搜索curl.cainfo 与 openssl.cafile,将其配置成你自己cacert.pem文件的路径
	curl.cainfo= "G:\phpstudy_pro\Extensions\php\php7.3.4nts\extras\ssl\cacert.pem "
	openssl.cafile= "G:\phpstudy_pro\Extensions\php\php7.3.4nts\extras\ssl\cacert.pem"


### 使用web3连接节点请求超时错误
	cURL error 28: Operation timed out after 1000 milliseconds with 0 out of 0 bytes received (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

	去该文件下修改超时时间，

	vendor\sc0vu\web3.php\src\RequestManagers\HttpRequestManager.php

	默认是1秒,看自己需要设置秒数
	$timeout = 1 
	public function __construct($host, $timeout = 1)
	{
	    parent::__construct($host, $timeout);
	    $this->client = new Client;
	}
