WEBSERVICE 函数请求一个允许跨域资源共享（CORS）的网站，最终得到处理成字符串的返回值。
FILTERJSON 函数将一个有效的json字符串转化为一个值、一个对象或者一个可以拆分的对象数组。
WEBSERVICE
如果请求不遵循同源策略的网站，或者请求的网站不允许来自源网站的跨域资源共享，会返回#VALUE!错误。该函数的返回结果是一个字符串类型。
FILTERJSON
FILTERJSON 函数将一个有效的json字符串转化为一个值、一个对象或者一个可以拆分的对象数组。
您可以同时使用FILTERJSON函数以及WEBSERVICE函数从服务器上获取json对象并在SpreadJS中使用。
