nodejs 循环引用JSON序列化错误的解决办法:TypeError: Converting circular structure to JSON

可以 使用 util.inspect 代替 JSON.stringify

var util = require("util")var a = {};
a.b = a;
a.c = "123"; 
// console.log(JSON.stringify(a)); // 报错console.log(util.inspect(a,{depth:null})); //depth:null 展开全部层级12345671234567

如上代码输出结果

{ b: [Circular], c: '123' }

    CORS: credentials mode is 'include'

    XMLHttpRequest cannot load http://localhost/Foo.API/token. The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'http://localhost:5000' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.
