Question

我在名为responseString的字符串中获取{"OTP":"5480"}之类的数据，我该如何使用它。

我的代码是。

@IBAction func signupButton() {
    var request = URLRequest(url: URL(string:"http://122.166.215.8:8090/RESTMVC/validateMobileNumber")!)
    request.httpMethod = "POST"

    let mobileNumberString : String = self.mobileNumberTextfield.text!

    let postString = ["mobileNumber":mobileNumberString]

    request.httpBody = try! JSONSerialization.data(withJSONObject: postString, options:.prettyPrinted)
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")

    let task = URLSession.shared.dataTask(with: request) { data, response, error in
        guard let data = data, error == nil else {                                                 // check for fundamental networking error
            print("error=\(error)")
            return
        }

        if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {           // check for http errors
            print("statusCode should be 200, but is \(httpStatus.statusCode)")
            print("response = \(response)")
        }
        let responseString = String(data: data, encoding: .utf8)
        var recived = [UInt8]()
        recived.append(contentsOf: data)
        print(responseString!)
        DispatchQueue.main.async(execute: {
            self.performSegue(withIdentifier: "OTPView", sender: nil)
        });
    }
    task.resume()
}

我想将该字符串更改为Array。或者有什么方法可以直接在String的位置获取Array？

访问＆＃34; OTP＆＃34;的价值您需要解析您的响应字符串并将其转换为Json字典，您可以使用以下代码实现此操作，只需在JSONSerialization.jsonObject中传递您的响应数据（使用：data，options：.allowFragments）

        do {
            let json = try JSONSerialization.jsonObject(with: data, options: .allowFragments) as! Dictionary<String, Any>

            if let otpValue = json["OTP"] {
                print("Otp value : \(otpValue)")
            }

        } catch {
            // Handle Exception
        }

你可以从下面的字典中获取otp。

print(responseString["OTP"])

如何从服务器解析数据？
