how does Angular HttpInterceptor get called?
问题 I'm trying to understand some code here: transfer_http.ts I'm trying to understand how it invalidates the cache: // Stop using the cache if there is a mutating call. if (req.method !== 'GET' && req.method !== 'HEAD') { this.isCacheActive = false; this.invalidateCacheEntry(req.url); } How do you get a situation when req.method !== 'GET'? I only use GET requests. 来源： https://stackoverflow.com/questions/55213396/how-does-angular-httpinterceptor-get-called
