在javascript中的抓取api中的Url查询字符串

如何传递查询字符串获取api javascript( https://github.com/github/fetch)？

var url = "http://www.abcd.com";
var query = {
    a: "test",b: 2
};

当我传递一些参数来获取时,应将以上内容转换为http://www.abcd.com?a=test\u0026amp;b=2

解决方法

var params = Object.keys(query)
                   .map((key) => encodeURIComponent(key) + "=" + encodeURIComponent(query[key]))
                   .join("&")
                   .replace(/%20/g,"+");

fetch(url + "?" + params);

或与选项对象 – but this will NOT work with GET and HEAD method：

fetch(url,{
    method: "POST",body: convertObjectToFormData(query)
}).then(...);

function convertObjectToFormData(obj) {
    var formData = new FormData();
    for (var key in query) {
        formData.append(key,query[key]);
    }
    return formData;
}
