在 NSUserDefaults 中存储 swiftyJSON 返回的数据时出现问题...相同的数据源

Question

很抱歉 post...大量数据。我在将 JSON 存储到 NSUserDefaults 时遇到问题。我已经构建了后端 PHP 服务，它在两个页面上都返回 JSON。我不确定为什么一个 JSON 可以存储而另一个不能存储....

提前致谢

一般这里是 PHP CODE 其中 returns 数据

header('Content-Type: application/json; charset=utf-8');
echo json_encode($rows,JSON_PRETTY_PRINT);

socialmedia.php RETURNS:

{
    "socialsites": [
        {
            "type": "Government",
            "entries": [
                {
                    "id": "1",
                    "name": "Pete",
                    "address": "https:\/\/website.com",

                    "active": "Y"
                }
            ]
        },
        {
            "type": "School",
            "entries": [
                {

                    "active": "Y"
                }
            ]
        },
        {
            "type": "Organizations",
            "entries": [
                {
                    "id": "3",
                    "name": "This Week Inserser",
                    "address": "https:\/\/www.resr.com",
                    "medium": "WWW",
                    "section": "Organizations",
                    "zip": "02055",
                    "active": "Y"
                }
            ]
        }
    ]
}

我可以使用

将它存储到 NSUSERDefault

var swiftyJsonVar: JSON = ""

var userdefaults = UserDefaults.standard
func gettheData(){
    if let test = self.userdefaults.object(forKey: "socialtableJSON"){
        print("beginkey")
        print(test)
        print("endkey")
    }
    let whichzip = userdefaults.object(forKey: "workingZip")
    Alamofire.request(openEVTjson,method:.get,parameters: ["zip_code":whichzip!]).validate().responseJSON{

        responseData in
        switch responseData.result{

        case .success(let jJson):
            self.keys.removeAll()
            self.post.removeAll()
            self.swiftyJsonVar = JSON(jJson)

            self.userdefaults.set(jJson, forKey: "socialtableJSON")

一切都很好......并且按预期工作....

        },
        {
            "category": "OPEN HOUSES"
        }

我去存储用

var swiftyJsonVar: JSON = ""
var userdefaults = UserDefaults.standard

Alamofire.request(openEVTjson,method:.get,parameters: ["zip_code":whichzip]).validate().responseJSON{

        responseData in
        switch responseData.result{

        case .success(let jJson):
            self.swiftyJsonVar = JSON(jJson)
            self.keys.removeAll()
            //let test = self.swiftyJsonVar.rawString()
            //print(test)
            self.userdefaults.set(jJson, forKey: "lastEventsJSON")
            self.userdefaults.set(Date().timeIntervalSince1970, forKey: "lastEventsLoad")

最后我得到

您需要 trim 通过删除 NSNull 值或用默认值替换它们来 JSON 。
