有人可以解释一下代码的安静性,特别是日志过滤器部分。
我想从机架文件中分配log_attributes_filter
,我在哪里拨打use MongodbLogger::RackMiddleware
,该怎么做?
# Rack middleware for mounted rack app (e.g Grape)
module MongodbLogger
class RackMiddleware
@@log_attributes_filter = nil
def self.log_attributes_filter=(filter)
@@log_attributes_filter = filter
end
def initialize(app)
@app = app
end
def call(env)
request = ::Rack::Request.new env
path = request.path.split('/')
log_attrs = {
params: request.params
}
log_attrs = @@log_attributes_filter.call(log_attrs) if @@log_attributes_filter
logger.mongoize(log_attrs) do
return @app.call(env)
end
end
end
end
之前我只是将其用作use MongodbLogger::RackMiddleware
,但现在我想过滤一些参数,我该如何正确分配@@log_attributes_filter
?
答案 0 :(得分:0)
找到了一条路。
use MongodbLogger::RackMiddleware
MongodbLogger::RackMiddleware.log_attributes_filter = lambda do |request|
begin
request[:params]["Password"] = "[FILTERED]"
request
rescue
request
end
end
