Config

1. Config is define at conf.json

2. An typical config

   {
   "key": //class identifier，if no "class" set below, "key" is the class name.
   {
   "class":"class_name", //Optional, class name"singleton":true,// Optional, singleton, default is false"pass_by_construct":true,//Optional, pass properties by construct, default is false"properties": {
   "name1": "{tpl_key_1}/apis/", //{tpl_key_1} is a template variable, will be replace when IoCFactory load this config."name2": "value",//set name2 as a constant"name3":"@key1"//set name3 as an instance of "key1"
   }
   },
   "key1":{
   ...
   }

3. Examples

   Config the class "Users" with conf.json.

   class Users{
   /** * @property({"default":"@default_db"}) $this->db will be inited as an instance of "default_db" by default. * @var PDO */public$db;
   /** * @property the dir for storing avatar files. */public$avatar_files;
   }

   And its config

   {
   "Users":{
   "properties": {
   "avatar_files": "/var/avatar_files/"
   }
   },
   "default_db":{
   "singleton":true, //Optional，we use singleton to share default_db in all requests."class":"PDO", //Optional"pass_by_construct":true, //Optional"properties":{
   "dsn":"mysql:host=127.0.0.1;port=3306;dbname=test;charset=UTF8",
   "username":"test",
   "passwd":"test"
   }
   }
   }

   phprs create Users with the config, if no "Users" config, phprs use new Users() to create "Users". Here we config it, so：

   1. phprs create "Users" with ReflectionClass::newInstanceWithoutConstructor(__construct not called)，
   2. set avatar_files
   3. call __construct In this sample，$db is specified not in Users's config, so the default value @default_db is used, and '@' means it an instance.

4. Config phprs

   {
   "phprs\\Router": {
   "properties": {
   "export_apis":true//Enable output api documents, if true, visit http://your-host:port/apis/ to get documents//,"hooks":["MyHook1","MyHook2"] //Enable hooks//,"url_begin":1 // if url is "/abc/123", then 1st path node "/abc/" will be ignored.
   } },
   "phprs\\Invoker": {
   "properties": {
   //"cache":"@invokeCache" //cache result of apis(the apis with @cache)
   } }
   /** if the property "cache" of phprs\\Invoker is set
   ,
   "invokeCache":{
   "class":"phprs\\util\\RedisCache",
   "singleton":true,
   "properties":{
   "serialize":true,
   "host":"127.0.0.1",
   "port":"6379"
   }
   }*//** //db config sample, and ezphp(https://github.com/caoym/ezsql) can work with PDO simply
   ,"db":{
   "singleton":true,
   "class":"PDO",
   "pass_by_construct":true,
   "properties":{
   "dsn":"mysql:host=127.0.0.1;dbname=xxxxxx;charset=UTF8",
   "username":"xxxxxx",
   "passwd":"xxxxxx" }
   }*/

}
