Got this working in the end by trial and error. This is the code that works for me:
c.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme
{
Description =
"JWT Authorization header using the Bearer scheme. \r\n\r\n Enter 'Bearer' [space] and then your token in the text input below.\r\n\r\nExample: \"Bearer 12345abcdef\"",
Name = "Authorization",
In = ParameterLocation.Header,
Type = SecuritySchemeType.ApiKey,
Scheme = "Bearer"
});
c.AddSecurityRequirement(new OpenApiSecurityRequirement()
{
{
new OpenApiSecurityScheme
{
Reference = new OpenApiReference
{
Type = ReferenceType.SecurityScheme,
Id = "Bearer"
},
Scheme = "oauth2",
Name = "Bearer",
In = ParameterLocation.Header,
},
new List<string>()
}
});
I suspect there are probably properties being set there that don’t actually need to be explicitly set, but the above is working for me.
