<p><strong>Parameter meaning:</strong>
The <code>auth</code> parameter is etcd root path, and the <code>code</code> parameter is expr execution expression.<br>
<strong>Injection object:</strong>
Currently, the objects injected by expr include: <code>param</code>, <code>proxy</code>, <code>rootcoord</code>, <code>querycoord</code>, <code>datacoord</code>, <code>quernode</code>, <code>datanode</code>. You can use this tool to get the running value of the object.<br>
<strong>Usage example:</strong>
1. Get a configuration: <code>param.CommonCfg.GracefulTime.GetValue()</code>
2. Get a property value in the proxy object: <code>proxy.address</code>
3. Determine whether a graph exists in the datanode: <code>datanode.flowgraphManager.HasFlowgraph("aaa")</code><br>
<strong>Limitations:</strong>
1. Variables cannot be modified.
2. Methods with non-basic type parameters cannot be executed.
3. Functions with multiple return values cannot be chained.</p>
