ios – Swift JSON错误：无法将’__NSDictionaryM’类型的值转换为’NSArray’

概述从webservice(API)解码 JSON时,我收到错误： Could not cast value of type '__NSDictionaryM' (0x1037ad8a8) to 'NSArray' (0x1037ad470). 我的代码： var kGetURL = "http://bitnami.local/cscart_demo/api/users"//var kGetURL 从webservice(API)解码 JSON时,我收到错误：

Could not cast value of type '__NSDictionaryM' (0x1037ad8a8) to 'NSArray' (0x1037ad470).

我的代码：

var kGetURL = "@R_502_6822@://bitnami.local/cscart_demo/API/users"//var kGetURL = "@R_502_6822@://localhost/fendy/getJson.PHP"var Json : Array<AnyObject> = [] overrIDe func vIEwDIDLoad() {    super.vIEwDIDLoad()    start() } func getData(data : NSData){    //error at this line :    Json = NSJsONSerialization.JsONObjectWithData(data,options: NSJsONReadingOptions.MutableContainers,error: nil) as! Array<AnyObject>    //error    tableVIEw.reloadData()}func start(){     var url : NSURL = NSURL(string: kGetURL)!    var data : NSData = NSData(contentsOfURL: url)!    getData(data)}

如果我将url更改为http://localhost/fendy/getjson.php,它的工作非常好.

如果我的网址是http://bitnami.local/cscart_demo/api/users,我会收到错误

来自webservice http://localhost/fendy/getjson.php的回复：

[{"ID":"17","name":"KFC","Message":"awesome"},{"ID":"18","name":"McDonald","Message":"good"},{"ID":"23","name":"Burger King","Message":"tasty"},{"ID":"38","name":"Pizza hut","Message":"yummy"},{"ID":"39","name":"Steak","Message":"very DelicIoUs"}]

来自webservice http://bitnami.local/cscart_demo/api/users的回复：

{"users":[{"user_ID":"4","user_login":"user_4","is_root":"N","timestamp":"1441608048","user_type":"C","status":"A","firstname":"","lastname":"","email":"fendy.w@mvig.net","company":"","company_ID":"1","company_name":"Simtech"},{"user_ID":"3","user_login":"customer","timestamp":"1441604240","firstname":"Customer","lastname":"Customer","email":"customer@example.com","company":"Simtech",{"user_ID":"1","user_login":"admin","is_root":"Y","user_type":"A","firstname":"John","lastname":"Doe","email":"robby@mvig.net","company":"Your company","company_ID":"0","company_name":null}],"params":{"page":1,"items_per_page":"10","sort_order":"asc","sort_by":"name","sort_order_rev":"desc","total_items":"3"}}

我认为它的风格是相同的,但为什么不使用网址http://bitnami.local/cscart_demo/api/users.谁有人可以帮忙？

解决方法 bitnami响应以{开头,因此它是 JSON object,对应于NSDictionary.另一个以[表示数组开头]开头.

您需要将Json的类型更改为Dictionary< String,AnyObject>,然后反序列化,如下所示：

Json = NSJsONSerialization.JsONObjectWithData(data,error: nil) as! Dictionary<String,AnyObject>
