(1) Environment

clear an environment variable: pm.environment.unset("variable_key")--recommend postman.clearEnvironmentVariable(variableName) postman.clearEnvironmentVariables()   get an environment variable: pm.environment.get("variable_key")--recommend postman.getEnvironmentVariable(variableName)   set an environment variable: pm.environment.set("variable_key", "variable_value")--recommend postman.setEnvironmentVariable(variableName, variableValue)--string   (2) Global variables   clear a global varibale: pm.globals.unset("variable_key") postman.clearGlobalVariable(variableName) postman.clearGlobalVariables()   set a global variable: pm.globals.set("variable_key", "variable_value"); postman.setGlobalVariable(variableName, variableValue)   get a global variable: pm.globals.get("variable_key") postman.getGlobalVariable(variableName)   (3) Json & string  JSON.parse()【從一個字串中解析出json物件】 例子： //定義一個字串 var data='{"name":"goatling"}' //解析物件 JSON.parse(data) 結果是： name:"goatling" JSON.stringify()【從一個物件中解析出字串】 var data={name:'goatling'} JSON.stringify(data) 結果是： '{"name":"goatling"}'   Getting an environment variable (whose value is a stringified object)：Json Setting a nested object as an environment variable：String
