【问题描述】：

http://beta.json-generator.com/api/json/get/E1jKVbplX我已经注册成功了。我对身份验证感到震惊。我访问了所有数据。但我对访问个人用户数据感到震惊。请参阅下面的代码并纠正我。 var email = “bhupal” var pwd = “k”

    //
    let parameters: Dictionary<String, AnyObject> = ["Email": email as AnyObject, "Password": pwd as AnyObject,"Type" : "Organization" as AnyObject,"Mode" : "Register" as AnyObject]

    //create the url with URL
    let url = URL(string: "http://beta.json-generator.com/api/json/get/E1jKVbplX  ")! //change the url
           let session = URLSession.shared

    //now create the URLRequest object using the url object
    var request = URLRequest(url: url)
    request.httpMethod = "GET" //set http method as GET



    do {
        request.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: .prettyPrinted) // pass dictionary to nsdata object and set it as request body

    } catch let error {
        print(error.localizedDescription)
    }

    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")
    //


    let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
        if error != nil
        {
            print ("ERROR")
        }
        else
        {
            if let content = data
            {
                do
                {
                    //Array
                    let myJson = try JSONSerialization.jsonObject(with: content, options: JSONSerialization.ReadingOptions.mutableContainers) as AnyObject
                    print(myJson)
                    print("--------")
                    print(myJson[0])
                    print(myJson[1])
                    print("--------")

                    email = myJson["Email"] as? String
                    pwd = myJson["Password"]  as? String
                    print("--------")

                    print(email)
                    print(pwd)


                    print("--------")

                }
                catch
                {

                }
            }
        }
    }
    task.resume()

【问题讨论】：

myJson 是Array。那么为什么myJson["Email"] 应该工作呢？那是为了一个字典。 myJson[0]["Email"] 而不是？

标签： ios json authentication swift3

【解决方案1】：

您的响应是字典数组，因此myJson[0] 将返回一个字典对象，在该字典中您应该尝试访问Email 或Password 的值。您可以尝试以下代码来访问电子邮件和密码：

for dict in myJson { // myJson is array and dict will of dictionary object

  let email = dict[Email]
  let password = dict[Password]

  print("--------")
  print("Email is : \(email)")
  print("Password is : \(password)")
  print("--------")
}

注意：你需要即兴发挥。
