Learning node (2) from 0 to 1 and building an http server
During the course of the previous section, we learned about the connection and differences between different module specifications. In this section, we officially started learning about node. First, we started from setting up an http server and running simple programs.
The $http.get and $http.post mentioned earlier are all based on $http shortcuts. The following is the complete $http:$http (config)$http accept a parameter config in JSON format:The format of config is as follows:{method: String, URL: String, Params:json object, data: Request data, headers: request header, Transformreq
