Question

我正在尝试查询Application Insights＆＃34; trace＆＃34;通过使用API快速入门页面（https://dev.applicationinsights.io/quickstart）上给出的C＃示例通过API获取数据，我认为我在理解调用工作的路径时遇到了问题。

以下内容摘自快速入门页面......

public class QueryAppInsights
{
    private const string URL = "https://api.applicationinsights.io/v1/apps/{0}/{1}/{2}?{3}";

    public static string GetTelemetry(string appid, string apikey, string queryType, string queryPath, string parameterString)
    {
        HttpClient client = new HttpClient();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        client.DefaultRequestHeaders.Add("x-api-key", apikey);
        var req = string.Format(URL, appid, queryType, queryPath, parameterString);
        HttpResponseMessage response = client.GetAsync(req).Result;
        if (response.IsSuccessStatusCode)
        {
            Console.WriteLine(response.Content.ReadAsStringAsync().Result);
            Console.WriteLine(response.StatusCode);
            return response.Content.ReadAsStringAsync().Result;
        }
        else
        {
            Console.WriteLine(response.Content.ReadAsStringAsync().Result);
            Console.WriteLine(response.StatusCode);
            return response.ReasonPhrase;
        }
    }
}

当我使用以下参数调用它时，出现以下错误。

{"error":{"message":"The requested path does not exist","code":"PathNotFoundError"}}
NotFound

public class TestSuite
{
    public void CallTest()
    {
        QueryAppInsights.GetTelemetry("My Application ID", "My API Key", "query", "traces", "timespan=P7D&query=traces%7C%20where%20message%20contains%20%1111a11aa1-1111-11aa-1a1a-11aa11a1a11a%22");
    }
}

当我称之为替换＆＃34;查询＆＃34; param with＆＃34; events＆＃34;我在顶部

返回了超过500行，其中包含以下内容

 {"@odata.context":"https://api.applicationinsights.io/v1/apps/GUID PLACE HOLDER/events/$metadata#traces","@ai.messages":[{"code":"AddedLimitToQuery","message":"The query was limited to 500 rows"} 



public class TestSuite
{
    public void CallTest()
    {
        QueryAppInsights.GetTelemetry("My Application ID", "My API Key", "events", "traces", "timespan=P7D&query=traces%7C%20where%20message%20contains%20%1111a11aa1-1111-11aa-1a1a-11aa11a1a11a%22");
    }
}

当我打电话给它取代＆＃34;事件＆＃34; param with＆＃34; metrics＆＃34;我收到以下错误：

{"error":{"message":"The requested item was not found","code":"ItemNotFoundError","innererror":{"code":"MetricNotFoundError","message":"Metric traces does not exist"}}}
NotFound

public class TestSuite
{
    public void CallTest()
    {
        QueryAppInsights.GetTelemetry("My Application ID", "My API Key", "metrics", "traces", "timespan=P7D&query=traces%7C%20where%20message%20contains%20%1111a11aa1-1111-11aa-1a1a-11aa11a1a11a%22");
    }
}

所以我不知道我传递查询的方式是不正确的，还是我正在尝试一些不可能的事情。该查询来自＆＃34;查询＆＃34;中的API资源管理器页面（https://dev.applicationinsights.io/apiexplorer/query）。＆GT; ＆＃34; GET / query＆＃34;部分，它按预期工作返回正确的行：

迹线 |其中消息包含＆＃34; 1111a11aa1-1111-11aa-1a1a-11aa11a1a11a＆＃34; （我已经用组成的GUID替换了真正的GUID）

万一有人遇到这个问题，我想分享一下我是如何成功的。基本上，我使用了快速启动（https://dev.applicationinsights.io/quickstart）页面上的示例提供的错误URL常量。我必须修改它才能查询Traces：

快速入门的给定示例：

private const string URL = "https://api.applicationinsights.io/v1/apps/{0}/{1}/{2}?{3}";

我的实施：

private const string URL = "https://api.applicationinsights.io/v1/apps/{0}/{1}?{2}{3}";

基本上移动查询字符串params以匹配GET /查询API资源管理器（https://dev.applicationinsights.io/apiexplorer/query）在发送查询时所执行的操作。
