<p>区别于私有化部署,用户对互联网上提供的在线服务,都希望能够建立在一个安全、可信赖的通信环境下。HTTPS 是用户普遍认知的一种传输安全协议,其本质是在 TCP/IP 协议栈的传输层(TCP)与应用层(HTTP)间增加 SSL/TLS 安全协议来保证通信安全。为了引入 SSL/TLS ,需要通过 CA 获取一份 SSL/TLS 证书。</p> | ||

<p><em>本文只针对 invoke 命令,基于 Dubbo 版本 2.6.7</em></p> | ||
<p>Dubbo Telnet Command <code>invoke</code> 命令的一般格式为 <code>invoke &lt;全限定名&gt;.&lt;方法名&gt;(&lt;参数&gt;,...,&lt;参数&gt;)</code>。其中参数需要能被 JSON 解析,即提取命令中的 <code>&lt;参数&gt;,...,&lt;参数&gt;</code> 部分,并包装上 <code>[]</code> 构成 <code>[&lt;参数&gt;,...,&lt;参数&gt;]</code> ,需要保证这个串是一个合法的 JSON Array。</p> | ||
