at t unwanted calls

Currently the project uses the YII framework, controller calls the façade method, the façade calls the adapter method, the adapter invokes the API method, the API encapsulates the SQL method, but in most cases it's just a simple call, but limited to the current project's rules, All have to write methods, and the method is simple return, so wrote a demo, simulated the next.

I. Background Under the micro-service architecture, our system is broken down into a number of single service micro services based on business. Each service has its own set of APIs to provide other service calls, so how to ensure security. Not that you want to call can be invoked, must have a certification mechanism, is our internal services issued by the request before we can call our interface. Need to pay attention to is that we are talking about

this pointer parameter after being processed by the compiler, so the type is doomed to be mismatched.However, if you declare run as a static type, the compiler converts the static form of a function into a global function without the this pointer, so its type can match the type of parameter that Pthread_create requires. However, a static member function of a class cannot access a non-static member of a class, but this can be resolved by passing the this pointer.Modified code: No other need to c

The Django project is running under Web server. However, it is often necessary to develop an external script to deal with the model of this Web project. For example, you would call the Django model to write data through an external Python script, or query the data. The following script demonstrates how to query a defined alias field with Django modes# _*_ coding: utf-8 _*_#!/usr/bin/env python__author__ = ‘xiaoke‘__date__ = ‘2018/4/27 14:38‘import sys,osimport django#定义django项目所在的路径【django版本1.9.
