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:)

PHP符号的TypeScript版本(没有URL转义版本)
/**
* Converts an object into a Cookie-like string.
* @param toSerialize object or array to be serialized
* @param prefix used in deep objects to describe the final query parameter
* @returns ampersand separated key=value pairs
*
* Example:
* ```js
* serialize({hello:[{world: "nice"}]}); // outputs "hello[0][world]=nice"
* ```

const serialize = (toSerialize: unknown = {}, prefix?: string) => {
const keyValuePairs = [];
Object.keys(toSerialize).forEach((attribute) => {
if (Object.prototype.hasOwnProperty.call(toSerialize, attribute)) {
const key = prefix ? `${prefix}[${attribute}]` : attribute;
const value = toSerialize[attribute];
const toBePushed =
value !== null && typeof value === "object"
? serialize(value, key)
: `${key}=${value}`;
keyValuePairs.push(toBePushed);
}
});
return keyValuePairs.join("&");
};

是这样的:
Serialize =函数(obj) { Var STR = []; For (var p in obj) if (obj.hasOwnProperty(p)) { str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]))); } 返回str.join(“&”); } console.log(序列化({ Foo:“你好”, 栏:“100%” })); / / foo =你好% 20 there&bar 25 = 100%
它还转换递归对象(使用PHP“数组”符号表示查询字符串):
serialize = function(obj, prefix) { var str = [], p; for (p in obj) { if (obj.hasOwnProperty(p)) { var k = prefix ? prefix + "[" + p + "]" : p, v = obj[p]; str.push((v !== null && typeof v === "object") ? serialize(v, k) : encodeURIComponent(k) + "=" + encodeURIComponent(v)); } } return str.join("&"); } console.log(serialize({ foo: "hi there", bar: { blah: 123, quux: [1, 2, 3] } })); // foo=hi%20there&bar%5Bblah%5D=123&bar%5Bquux%5D%5B0%5D=1&bar%5Bquux%5D%5B1%5D=2&bar%5Bquux%5D%5B2%5D=3
对于TS
const convertQueryToString = (data: { [x: string]: any }): string => { const serialize = (obj: { [x: string]: any }, prefix?: string): string => { const str = []; let p; for (p in obj) { if (obj.hasOwnProperty(p)) { const k = prefix ? `${prefix}[${p}]` : p; const v = obj[p]; str.push( v !== null && typeof v === 'object' ? serialize(v, k) : `${encodeURIComponent(k)}=${encodeURIComponent(v)}` ); } } return str.join('&'); }; return serialize(data); };
这是一个开箱即用的。net后端解决方案。我已经采取了这个线程的主要答案,并更新它以适应我们的。net需求。
function objectToQuerystring(params) {
var result = '';
function convertJsonToQueryString(data, progress, name) {
name = name || '';
progress = progress || '';
if (typeof data === 'object') {
Object.keys(data).forEach(function (key) {
var value = data[key];
if (name == '') {
convertJsonToQueryString(value, progress, key);
} else {
if (isNaN(parseInt(key))) {
convertJsonToQueryString(value, progress, name + '.' + key);
} else {
convertJsonToQueryString(value, progress, name + '[' + key+ ']');
}
}
})
} else {
result = result ? result.concat('&') : result.concat('?');
result = result.concat(`${name}=${data}`);
}
}
convertJsonToQueryString(params);
return result;
}
let data = {
id:1,
name:'Newuser'
};
const getqueryParam = data => {
let datasize = Object.keys(data).length;
let initial = '?';
Object.keys(data).map(function (key, index) {
initial = initial.concat(`${key}=${data[key]}`);
index != datasize - 1 && (initial = initial.concat('&'));
});
console.log(initial, 'MyqueryString');
return initial;
};
console.log(getqueryParam(data))//You can get the query string here
If you have baseUrl means to get full query use
baseUrl concat (getqueryParam(数据)。
我的实现编码一个对象作为一个查询字符串,使用减少:
export const encodeAsQueryString = (params) => (
Object.keys(params).reduce((acc, key)=>(
params.hasOwnProperty(key) ? (
[...acc, encodeURIComponent(key) + '=' + encodeURIComponent(params[key])]
) : acc
), []).join('&')
);
