1.JsonPath:像xpath一样，提取json数值

2.json schema：gibhub -> jsonschema

from jsonshema import validate
schema = {
   "type":"object",
  "properties":{
  "price":{"type":"number"},
  "name":{"type":"string"}
}   
}
validate(instance={"name":"Eggs", "price":34.99}, schema=schema)

3.restful，同一个api，通过get,post,put,delete，来区别方法
