Dotnet 6 HttpLogging - filter out some controllers

Question

I am using AddHttpLogging middleware for my Dotnet 6 web api project. For diagnostic purposes I have such configuration:

                var loggingFields = HttpLoggingFields.RequestPropertiesAndHeaders |
                                    HttpLoggingFields.ResponsePropertiesAndHeaders |
                                    HttpLoggingFields.ResponseStatusCode |
                                    HttpLoggingFields.RequestQuery |
                                    HttpLoggingFields.RequestBody;

Due to sensitive information, I want to prevent logging request body of some controllers. How can I them filter out?

Answer 1

In your case, use 'ExcludeFilter' method to prevent logging request body of some controllers, it is provided by the AddHttpLogging middleware. Like this;

app.UseAddHttpLogging(options => {
options.ExcludeFilter = context =>
    context.ActionDescriptor.ControllerTypeInfo.FullName == "YourController";
});

Or another way is;

app.UseAddHttpLogging(options => {
options.ExcludeFilter = excludeFilterOptions => {
    excludeFilterOptions.ControllerTypeNames.Add("YourController");
};
});

(Edited) Update: For some reason above solution didn't work. So I found another solution that worked. Here's a demo I coded for you; https://github.com/usama-mirza/HttpLoggingWithFilter

Try the following instead of app.UseHttpLogging();

app.UseWhen(
context => !context.Request.Path.StartsWithSegments("/Sensitive"), //SensitiveController.cs
builder => builder.UseHttpLogging());
