openapp.jdmobile://virtual?params={"category":"jump","des":"m","url":"https://u.jd.com/nQo1Y5A","union_open":"union_cps"}

这个链接"openapp.jdmobile://virtual?params={"category":"jump","des":"m","url":"https://u.jd.com/nQo1Y5A","union_open":"union_cps"}"是用来在京东APP中打开指定商品的。
具体使用的代码如下：

static func goJD(_ url : String){
    KeplerApiManager.sharedKPService()?.openKeplerPage(withURL: url, userInfo: nil, successCallback: {
        debugPrint("open jd app success")
    }, failedCallback: { code, msg in
        debugPrint("open jd error code: ", code)
        otherGoJD(url)
    })
}

static func otherGoJD(_ url : String) {
    let jdDict = ["category":"jump", "des":"getCoupon", "url":url ]
    guard let jdStr = jdDict.formatJSON() else { return }
    let urlStr = "openapp.jdmobile://virtual?params=\(jdStr)"
    let utf8Str = urlStr.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)
    var openSuccess = false
    if let jumpURL = URL(string: utf8Str ?? "") {
        let isCanOpen = UIApplication.shared.canOpenURL(jumpURL)
        if isCanOpen {
            UIApplication.shared.open(jumpURL, options: [:], completionHandler: nil)
            openSuccess = true
        }
    }
    if (openSuccess == false) {
        UIApplication.shared.open(URL(string: url)!, options: [:], completionHandler: nil)
    }
}

通过调用goJD方法，传入京东商品的URL，即可在京东APP中打开该商品页面。如果无法打开京东APP，则会在浏览器中打开该商品链接。
对于京东的URL Scheme，可以在网上搜索到具体的参数传递方式。
