快速解析 Json

Question

您好，我对 iOS 编程很陌生。我必须使用 api 登录并获取“成员数据”并显示它。 这是我到目前为止所拥有的：

 @IBAction func loginButton(_ sender: Any) {


       let usr = usernameTextField.text
      let pwdCode = passwordTextField.text
let iturl = NSURL(string: "something?UserName=\(usr!)&Password=\(pwdCode!)")


            let session = URLSession.shared
              var request = URLRequest(url: iturl as! URL)
            do {

                let auth = try JSONSerialization.data(withJSONObject: login, options: .prettyPrinted)
               request.setValue("application/json", forHTTPHeaderField: "Content-Type")
                   request.httpMethod = "POST"
                    request.httpBody = auth

                let task = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
                    print("Got data \(data)  response: \(response)with error \(error)")
                    print("Done.")
                })task.resume()

在回复中我收到了这个

 Got data Optional(41 bytes)
response: Optional(<NSHTTPURLResponse: 0x608000228760> { URL: something } { status code: 200, headers {
        "Cache-Control" = "s-maxage=0";
        "Content-Encoding" = gzip;
        "Content-Security-Policy" = "referrer origin-when-cross-origin";
        "Content-Type" = "application/json;charset=UTF-8";
        Date = "Mon, 19 Jun 2017 07:08:33 GMT";
        "Transfer-Encoding" = Identity;
        Vary = "Accept-Encoding";
        "X-XSS-Protection" = "1; mode=block";
    } }) with error nil
Done.

这是 url 给出的 Json 响应：

{  
   "nonprimary":null,
   "memtier":[  

   ],
   "memcard":[  
      {  
         "attributes":{  
            "type":"Membership_card__c",
            "url":"/services/data/v37.0/something"
         },
         "Effective_End_Date__c":"2018-04-13",
         "Effective_Start_Date__c":"2017-04-13",
         "Member__c":"a0A2800000Psomething",
         "Id":"a0B28000something"
      }
   ],
   "member":{  
      "attributes":{  
         "type":"Member__c",
         "url":"/services/data/v37.0/sobjects/something"
      },
      "Contact__c":"0032800000wk79XAAQ",
      "Enrollment_Channel__c":"Web",
      "Registered_date__c":"2017-04-13",
      "Name":"something",
      "Member_Image__c":"<img src=\"https://ap2something" width=\"300\" height=\"281\"></img>",
      "Member_Number__c":"000000974",
      "Membership_Card__c":"a0B2800000IJPn7EAH",
      "Member_Tier__c":"Ruby",
      "Member_Type__c":"Individual",
      "Points__c":1656009,
      "Program__c":"a0G2800000jXisqEAC",
      "Status__c":"Active",
      "Tier__c":"a0P2800000AKJxMEAX",
      "Id":"a0A2800000PM4DlEAL"
   },
   "contact":null,
   "account":{  
      "attributes":{  
         "type":"Account",
         "url":"/services/datasomethingSZyxAAH"
      },
      "Name":"something",
      "FirstName":"somethingd",
      "LastName":"somethingir",
      "PersonEmail":"somethingr@gmail.com",
      "PersonHasOptedOutOfEmail":false,
      "PersonMailingStreet":"something ",
      "PersonBirthdate":"1992-07-19",
      "Passport__c":"JHdd546TG",
      "PersonMailingCountry":"Saudi Arabia",
      "PersonMailingCity":"Jeddah",
      "PersonMobilePhone":"+9667887575763",
      "National_ID__c":"P435345",
      "PersonDoNotCall":false,
      "Id":"0012800001FSZyxAAH"
   }
}

这是我的最终实现应该有的：

你好（人名），你的卡号（会员卡）你是类型（Member_Type__c）并且有积分（Points__c）

有人可以指点我一个教程或给我一些资源来了解如何实施下一步吗？

谢谢。

如果您想获取成员详细信息，则可以尝试此示例。抱歉，我使用了您的文件而不是 URL 链接。

do{
            let file = Bundle.main.url(forResource: "JsonFile", withExtension: "json"); //Get file
            let data = try Data(contentsOf: file!); //Get content of file

            let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as! [String:Any]; // Get data as json object

            for data in json["member"] as! [String: Any]{
                print(data.value)


            }

        }catch let err{
            print(err);
        }

输出：

2017-04-13
Web
000000974
Individual
Active
1656009
a0A2800000PM4DlEAL
Ruby
<img src="https://ap2something
{
    type = "Member__c";
    url = "/services/data/v37.0/sobjects/something";
}
something
0032800000wk79XAAQ
a0B2800000IJPn7EAH
a0P2800000AKJxMEAX
a0G2800000jXisqEAC

对于 URL，您可以使用以下示例

URLSession.shared.dataTask(with: "some url") { (data, response, error) in
                    if error != nil{ //If error has some value then return
                        print(error);
                        return;
                    }

                    do{
                        let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as! [String:Any];
                        for data in json["member"] as! [String: Any]{
                            print(data.value)
                        }

                    }
                }

Answer 2

           if let data = data,
            let json = try? JSONSerialization.jsonObject(with: data, options: []) as? [String: Any] {
            for case let result in json["Key"] {



                }
            }
        }
