azure app insights从url获取字符串的一部分，并将其显示在名称列中

我正在使用azure app insights，我想从url解析字符串的一部分，并在名称列中显示该部分

requests
| where user_AuthenticatedId != ""
and url contains "reports" and user_AuthenticatedId == "xxx" 
| project timestamp, user_AuthenticatedId, client_CountryOrRegion, client_OS, url,name 
| order by timestamp asc nulls last

例如，我获取的url为https://localhost:80/api/external-reports/blob/39/test 01b/false，因此我想从中获取test 01b，并在name列中显示它

---

我不知道怎么做。

有些功能可能会有所帮助

首先，您可以使用方法获取不同的url部分。例如，给定urlhttps://localhost:80/api/external-报告/blob/39/test 01b/false：

requests
| project parse_url(url)

输出：

{"Scheme":"https","Host":"localhost","Port":"80","Path":"/api/external-reports/blob/39/test 01b/false","Username":"","Password":"","Query Parameters":{},"Fragment":""} 

["","api","external-reports","blob","39","test 01b","false"]    

test 01b

• 您可以使用以下方法进一步拆分结果：

输出：

{"Scheme":"https","Host":"localhost","Port":"80","Path":"/api/external-reports/blob/39/test 01b/false","Username":"","Password":"","Query Parameters":{},"Fragment":""} 

["","api","external-reports","blob","39","test 01b","false"]    

test 01b

• 要获取所需零件，可以使用索引：

输出：

{"Scheme":"https","Host":"localhost","Port":"80","Path":"/api/external-reports/blob/39/test 01b/false","Username":"","Password":"","Query Parameters":{},"Fragment":""} 

["","api","external-reports","blob","39","test 01b","false"]    

test 01b

• 当使用的索引大于部分数时，将返回空结果。您可以使用以下函数将其替换为自己的值：

---

当索引超出范围或零件为空时，它显示unknown。
