这里有一个简单的答案，在转换过程中同时处理字符串和数组。

jsonToQueryString: function (data) {
        return Object.keys(data).map((key) => {
            if (Array.isArray(data[key])) {
                return (`${encodeURIComponent(key)}=${data[key].map((item) => encodeURIComponent(item)).join('%2C')}`);
            }
            return(`${encodeURIComponent(key)}=${encodeURIComponent(data[key])}`);
        }).join('&');
    }

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); };

对用户187291接受的解决方案的一个小修改:

serialize = function(obj) {
   var str = [];
   for(var p in obj){
       if (obj.hasOwnProperty(p)) {
           str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
       }
   }
   return str.join("&");
}

检查对象上的hasOwnProperty使JSLint和JSHint高兴，它防止意外序列化对象的方法或其他东西，如果对象不是一个简单的字典。有关JavaScript编程语言的代码约定的语句，请参阅上一段。

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

在讨论了一些最重要的答案之后，我编写了另一个实现，它也可以处理一些边缘情况

function serialize(params, prefix) {                
    return Object.entries(params).reduce((acc, [key, value]) => {
        // remove whitespace from both sides of the key before encoding
        key = encodeURIComponent(key.trim());

        if (params.constructor === Array ) {
          key = `${prefix}[]`;
        } else if (params.constructor === Object) {
          key = (prefix ? `${prefix}[${key}]` : key);
        }

        /**
         *  - undefined and NaN values will be skipped automatically
         *  - value will be empty string for functions and null
         *  - nested arrays will be flattened
         */
        if (value === null || typeof value === 'function') {
            acc.push(`${key}=`);
        } else if (typeof value === 'object') {
            acc = acc.concat(serialize(value, key));
        } else if(['number', 'boolean', 'string'].includes(typeof value) && value === value) { // self-check to avoid NaN
            acc.push(`${key}=${encodeURIComponent(value)}`);
        }

        return acc;
    }, []);
}

function objectToQueryString(queryParameters) {
    return queryParameters ? serialize(queryParameters).join('&'): '';
}

let x = objectToQueryString({
    foo: 'hello world',
    bar: {
      blah: 123,
      list: [1, 2, 3],
        'nested array': [[4,5],[6,7]] // will be flattened
    },
    page: 1,
    limit: undefined, // field will be ignored
    check: false,
    max: NaN, // field will be ignored
    prop: null,
    ' key value': 'with spaces' // space in key will be trimmed out
});
  
console.log(x); // foo=hello%20world&bar[blah]=123&bar[list][]=1&bar[list][]=2&bar[list][]=3&bar[nested%20array][][]=4&bar[nested%20array][][]=5&bar[nested%20array][][]=6&bar[nested%20array][][]=7&page=1&check=false&prop=&key%20value=with%20spaces

如果您需要发送任意对象，那么GET是一个坏主意，因为有限制的url长度，用户代理和web服务器将接受。我的建议是建立一个名称-值对数组来发送，然后建立一个查询字符串:

function QueryStringBuilder() {
    var nameValues = [];

    this.add = function(name, value) {
        nameValues.push( {name: name, value: value} );
    };

    this.toQueryString = function() {
        var segments = [], nameValue;
        for (var i = 0, len = nameValues.length; i < len; i++) {
            nameValue = nameValues[i];
            segments[i] = encodeURIComponent(nameValue.name) + "=" + encodeURIComponent(nameValue.value);
        }
        return segments.join("&");
    };
}

var qsb = new QueryStringBuilder();
qsb.add("veg", "cabbage");
qsb.add("vegCount", "5");

alert( qsb.toQueryString() );
