Is there a way to capture the response from requests served by OAuth? Specifically, I need to log the request and response from OAuthAuthorizationServerProvider.GrantResourceOwnerCredentials().
I've tried extending OwinMiddleware and overriding Invoke as shown in this post, but I'm unable to read the response body. I'd like to use a message handler as this post demonstrates, but I don't have UseHttpMessageHandler on my AppBuilder object.
Any help would be greatly appreciated. Thank you!
Update
Modifying the example provided in Brock's excellent video, here's what I need to do:
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.Use(typeof(MW1));
app.Map("/api", fooApp => {
fooApp.Use<MW2>();
});
}
}
public class MW1 {
Func<IDictionary<string, object>, Task> next;
public MW1(Func<IDictionary<string, object>, Task> next) {
this.next = next;
}
public async Task Invoke(IDictionary<string, object> env) {
var ctx = new OwinContext(env);
await next(env);
// I need to be able to read: <h1>MW2 called</h1> written by MW2
var body = ctx.Response.Body;
// body.CanRead = False
}
}
public class MW2 {
Func<IDictionary<string, object>, Task> next;
public MW2(Func<IDictionary<string, object>, Task> next) {
this.next = next;
}
public async Task Invoke(IDictionary<string, object> env) {
var ctx = new OwinContext(env);
await ctx.Response.WriteAsync("<h1>MW2 called</h1>");
await next(env);
}
}
I actually need to read the response sent from the OAuth provider, but I assume it would be the same process.
