微信小程序带cookie的request请求代码封装

const request = function (obj) {
    let key = 'cookie'
    let cookie = wx.getStorageSync(key);

    if (!('fail' in obj)) {
        obj.fail = function (err) {
        }
    }
    if (!('complete' in obj)) {
        obj.complete = function (res) {
        }
    }

    wx.request({
        url: obj.url,
        data: obj.data,
        method: obj.method,
        header: {
            "Content-Type": "application/x-www-form-urlencoded",
            "Cookie": cookie
        },
        success: res => {
            if (res.header) {
                if ('Set-Cookie' in res.header) {
                    wx.setStorageSync(key, res.header['Set-Cookie']);
                }
                else if ('set-cookie' in res.header) {
                    wx.setStorageSync(key, res.header['set-cookie'])
                }
            }
            obj.success(res);
        },
        fail: err => {
            if (res.header) {
                if ('Set-Cookie' in res.header) {
                    wx.setStorageSync(key, res.header['Set-Cookie']);
                }
                else if ('set-cookie' in res.header) {
                    wx.setStorageSync(key, res.header['set-cookie'])
                }
            }
            obj.fail(err);
        },
        complete: res => {
            obj.complete(res);
        }
    });
}

module.exports = {
    request: request
}
