小编tri*_*ity的帖子

我正在主页上加载一些后端 api 数据 ngOnInit()

export class MyComponent{
 homepagedata:any; // displayed on the html 

ngOnInit() {
   this.homepagedata=// calling service 
}

}

这是我的路线

{
    path: 'home',
    component: HomeComponent,
    children: [


        {  
            path: 'dashboard/:userid', // 
            component: DashboardComponent,
        },

    ]
}

因此，当我导航到仪表板，然后再次导航到主页时，我的主页组件没有刷新，可能是因为ngOnInit()被调用了一次。ngOnit()每次导航到主页时如何调用它。我尝试过，ngAfterViewInit()但它也只调用了一次.

我在这里发现了一个类似的问题。但在这里它是在函数调用之后导航，这不是我的情况。我的情况中有很多子组件，我正在寻找一种适合所有人的解决方案。谢谢

我在弹性搜索中创建了一个索引，看起来像

{"amazingdocs":{"aliases":{},"mappings":{"properties":{"Adj Close":{"type":"text"},"Close":{"type":"text"},"Date":{"type":"text"},"High":{"type":"text"},"Low":{"type":"text"},"Open":{"type":"text"},"Volume":{"type":"text"}}},"settings":{"index":{"creation_date":"1563168811565","number_of_shards":"1","number_of_replicas":"1","uuid":"k2wCARIETvufWmrdkDOtyw","version":{"created":"7020099"},"provided_name":"amazingdocs"}}}}

但是现在当我尝试使用 kibana 在其中插入文档时，出现以下错误

{
  "error": {
    "root_cause": [
      {
        "type": "parse_exception",
        "reason": "unknown key [High] for create index"
      }
    ],
    "type": "parse_exception",
    "reason": "unknown key [High] for create index"
  },
  "status": 400
}

语法，我遵循的是

PUT /amazingdocs/ 
{
    "Date": "1960-10-06",
    "Open": "53.720001",
    "High": "53.720001",
    "Low": "53.720001",
    "Close": "53.720001",
    "Adj Close": "53.720001",
    "Volume": "2510000"
}

此外，当我尝试插入具有类似字段的批量数据时，出现以下错误

"{"took":66336,"errors":true,"items":[{"index":{"_index":"amazingdocs","_type":"_doc","_id":"O7o_9GsBcUaBu1lEWjja","status":400,"error":{"type":"mapper_parsing_exception","reason":"failed to parse","caused_by":{"type":"not_x_content_exception","reason":"Compressor detection can only be called on some xcontent bytes or compressed xcontent bytes"}}}}
