问题 I want to use the session ID to identify the records in the database for anonymous user. When the user logs in, I would like to bind/relate the data to the user id. However, after logging in the session id is automatically changed by what I lose data binding with the user. How can I keep the session id after logging in order to bind the user id to the data, and then change the session id? 回答1: Upon authentication, session should be migrated, unless configured otherwise. Indeed, the session ID

问题 I have types like this: type GenericType<T, K extends keyof T = keyof T> = { name: K; params: T[K] } type Params = { a: 1; b: 2; } const test: GenericType<Params> = { name: "a", params: 2 } When I create an object like test that has property name: "a" I want the type of params to be inferred so that params must be 1 . In my example params has type 1 | 2 which is Params[keyof Params] . But since name is "a" I think it should be possible to limit the type of params to just 1 without specifying

问题 I am getting a huge amount of of logging when I install the Google-Mobile-Ads-SDK cocoapod. Some seem to be completely unrelated but somehow are because completely removing the Google-Mobile-Ads-SDK pod gets rid of all the logging. Here is what I have: Podfile target 'myapp' do # Comment the next line if you don't want to use dynamic frameworks use_frameworks! pod 'Google-Mobile-Ads-SDK' end Here are the pod files: I've tried adding FIREBASE_ANALYTICS_COLLECTION_DEACTIVATED=YES IS_MEASUREMENT

问题 The main question I have is how can I get a textfile that I have in Linux to display properly in PowerShell. In Linux, I have text files with some special characters, and in fact Notepad displays the text file exactly as it is displayed in Linux: Unfortunately, my program prints to my Linux Terminal, and thus I need the same output in my Windows terminal. I have seen through other answers that I need to use a TrueType font, so I am using Lucidia Console on my Linux device, the encoding is UTF
