在Application Insights中查看POST请求正文

您可以简单地实现自己的遥测初始化器：

例如，在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下面：

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将其添加到配置中：

TelemetryConfiguration.Active.TelemetryInitializers.Add(new RequestBodyInitializer());

然后在Analytics（分析）中查询它：

requests | limit 1 | project customDimensions.body
