是否可以在 Application Insights 中查看 POST 请求正文?
Is it possible to view POST request body in Application Insights?
我可以看到请求详细信息,但看不到应用洞察中发布的有效负载.我必须用一些编码来跟踪这个吗?
I can see request details, but not the payload being posted in application insights. Do I have to track this with some coding?

推荐答案
您可以简单地实现自己的 遥测初始化器:
You can simply implement your own Telemetry Initializer:
例如,下面是提取有效负载并将其添加为请求遥测的自定义维度的实现:
For example, below an implementation that extracts the payload and adds it as a custom dimension of the request telemetry:
public class RequestBodyInitializer : ITelemetryInitializer
{
public void Initialize(ITelemetry telemetry)
{
var requestTelemetry = telemetry as RequestTelemetry;
if (requestTelemetry != null && (requestTelemetry.HttpMethod == HttpMethod.Post.ToString() || requestTelemetry.HttpMethod == HttpMethod.Put.ToString()))
{
using (var reader = new StreamReader(HttpContext.Current.Request.InputStream))
{
string requestBody = reader.ReadToEnd();
requestTelemetry.Properties.Add("body", requestBody);
}
}
}
}
然后通过 配置文件 或通过代码:
Then add it to the configuration either by configuration file or via code:
TelemetryConfiguration.Active.TelemetryInitializers.Add(new RequestBodyInitializer());
然后在 Analytics 中查询:
Then query it in Analytics:
requests | limit 1 | project customDimensions.body
