是否有一个快速和简单的方法来编码JavaScript对象到字符串，我可以通过GET请求传递?
没有jQuery，没有其他框架-只有纯JavaScript:)
当前回答
如果你想将整个对象作为一个参数传递，例如，?filter={param1: "val1"， param2: "val2"}:
const serializeObject = (obj) => {
let objStr = JSON.stringify(obj);
objStr = objStr.replace(/\{/g, encodeURIComponent("{"));
objStr = objStr.replace(/}/g, encodeURIComponent("}"));
objStr = objStr.replace(/:/g, encodeURIComponent(":"));
return objStr;
};
let res = serializeObject({param1: "val1", param2: "val2"});
console.log("serializeObject:", res); //%7B"param1"%3A"val1","param2"%3A"val2"%7D
console.log("serializeObject-decoded:", decodeURIComponent(res)); //{"param1":"val1","param2":"val2"}

还有一个很受欢迎的图书馆，qs。您可以通过以下方式添加:
yarn add qs
然后像这样使用它:
import qs from 'qs'
const array = { a: { b: 'c' } }
const stringified = qs.stringify(array, { encode: false })
console.log(stringified) //-- outputs a[b]=c
使用Node.js v6.6.3
const querystring = require('querystring')
const obj = {
foo: 'bar',
baz: 'tor'
}
let result = querystring.stringify(obj)
// foo=bar&baz=tor
参考:查询字符串
const buildSortedQuery = (args) => { 返回种(args) .sort () .map(key => { 返回window.encodeURIComponent(关键) + ' = ' + window.encodeURIComponent (args(例子)); }) . join (' & '); }; console.log (buildSortedQuery ({ Foo:“你好”， 栏:“100%” })); / /酒吧= 100% 25 foo =你好% 20
我对JSON stringfier进行了比较，结果如下:
JSON: {"_id":"5973782bdb9a930533b05cb2","isActive":true,"balance":"$1,446.35","age":32,"name":"Logan Keller","email":"logankeller@artiq.com","phone":"+1 (952) 533-2258","friends":[{"id":0,"name":"Colon Salazar"},{"id":1,"name":"French Mcneil"},{"id":2,"name":"Carol Martin"}],"favoriteFruit":"banana"}

其中最短的是URL对象表示法。
const serialize = obj => Object.keys(obj).reduce((a, b) =>
a.push(encodeURIComponent(b) + "=" + encodeURIComponent(obj[b])) && a,
[]).join("&");
电话:
console.log(serialize({a:1,b:2}));
// output: 'a=1&b=2
'
