node.js - 如何在节点js中将urlencoded数组转换为json

Question

我有form-urlencoded如下要求：

但我必须将此请求转换为 json，如下所示：

{
"version":4.2,
"auth_token": "xxxxxxxx",
"zcontacts":[
    { "phone": "xxxxx", "name": "xxxx" },
    { "phone": "112", "name": "Distress Number" },
    { "phone": "1800-300-xxxx", "name": "UIDAI" },
    { "phone": "44 xxxxx, "name": "Ab zz" }
]
}

下面是我正在尝试的代码：

index(req_data) {
    const self = this;

    return new Promise((resolve, reject) => {
        console.log(typeof req_data)

        let req_body = {}
        req_body.version = req_data.version;
        req_body.auth_token = req_data.auth_token;
        let contacts_list = [];
        return Promise.each(req_data.zcontacts,(contact, key, length) => {
            // Logic starts from here
            if(key === 0) {
                contacts_list.push({
                    phone: req_data.zcontacts[key],
                    name: req_data.zcontacts[(key+1)]
                })
            } else if(key > 0) {
                contacts_list.push({
                    phone: req_data.zcontacts[(key+3)],
                    name: req_data.zcontacts[(key+4)]
                })
            }
        }).then(() => {
            req_body.zcontacts = contacts_list;
            resolve(req_body)
        });

谁能建议在循环下的代码中应该改变什么？

我得到了它：

return Promise.each(req_data.zcontacts,(contact, key, length) => {
        if(key % 2 === 0) {
          contacts_list.push({
            phone: req_data.zcontacts[key],
            name: req_data.zcontacts[(key+1)]
          })
        }
    }).then(() => {
        req_body.zcontacts = contacts_list;
        resolve(req_body)
    });
