vue问题集锦

1、vue项目部署问题

网站部署如下：

运行vue项目报错：

未能加载文件或程序集“Microsoft.AspNet.TelemetryCorrelation”或它的某一个依赖项。系统找不到指定的文件

百度了好久都没找到答案，请教同事说父网站xinyan网站配置加：<location path="." inheritInChildApplications="false"></location>，具体如下：

 <location path="." inheritInChildApplications="false">
	  <system.webServer>
		<httpProtocol>
		  <customHeaders>
			<add name="Access-Control-Allow-Origin" value="*" />
			<add name="Access-Control-Allow-Headers" value="Content-Type" />
			<add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />
		  </customHeaders>
		</httpProtocol>
		<handlers>
		  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
		  <remove name="OPTIONSVerbHandler" />
		  <remove name="TRACEVerbHandler" />
		  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
		</handlers>
		<modules>
		  <remove name="TelemetryCorrelationHttpModule" />
		  <add name="TelemetryCorrelationHttpModule" type="Microsoft.AspNet.TelemetryCorrelation.TelemetryCorrelationHttpModule, Microsoft.AspNet.TelemetryCorrelation" preCondition="integratedMode,managedHandler" />
		</modules>
	  </system.webServer>
  </location>

2、vue路由监听无效

普通写法无，换成以下写法才有效

watch: {
    $route: {
      immediate: true,
      handler(val) {
        this.currentIndex = this.$route.query.index;
        let temp = this.InfoList[this.currentIndex];
        if (temp) {
          this.currentName = temp.name;
        }
      }
    }
  }
