swift - ZOHO CRM 未获得刷新 token 作为响应

Question

我正在 iOS 和 android 中开发应用程序，因为我正在集成 ZOHO CRM。我使用 OAuth2.0 进行身份验证，之后我使用 REST API 来获取“刷新 token ”，但我只得到“访问 token ”。有下面的代码来获取 token 。如何获取刷新 token ？

self.getCodeFromCRM(client_id: Client_ID,
                            clientSecret: secID,
                            authURL: "https://accounts.zoho.in/oauth/v2/auth",
                            accessURL: "offline",
                            responseType: "code",
                            callBackURL: "zohoapp://",
                            scope: "ZohoCRM.modules.contacts.all",//ZohoCRM.users.ALL
                            state: "code")

获取代码后调用此 API 获取刷新和访问 token 。

func getZohoReferenceToken()
    {
        let headers = [
            "Content-Type": "application/x-www-form-urlencoded",
            "User-Agent": "PostmanRuntime/7.13.0",
            "Accept": "*/*",

            "Connection": "keep-alive",
            "cache-control": "no-cache"
        ]

        let postData = NSMutableData(data: "client_id=\(Client_ID)".data(using: String.Encoding.utf8)!)
        postData.append("&client_secret=\(secID)".data(using: String.Encoding.utf8)!)
        postData.append("&redirect_uri=zohoapp://".data(using: String.Encoding.utf8)!)
        postData.append("&code=\(code)".data(using: String.Encoding.utf8)!)
        postData.append("&grant_type=authorization_code".data(using: String.Encoding.utf8)!)
        postData.append("&prompt=consent".data(using: String.Encoding.utf8)!)

        let request = NSMutableURLRequest(url: NSURL(string: "https://accounts.zoho.in/oauth/v2/token")! as URL,
                                          cachePolicy: .useProtocolCachePolicy,
                                          timeoutInterval: 10.0)
        request.httpMethod = "POST"
        request.allHTTPHeaderFields = headers
        request.httpBody = postData as Data

        let session = URLSession.shared
        let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
            if (error != nil) {
                print(error!)
            } else {
                let httpResponse = response as? HTTPURLResponse
                print(httpResponse!)

                do {
                    //create json object from data
                    if let json:NSDictionary = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? NSDictionary
                    {
                        // UserDefaults.standard.set(json.value(forKey: "access_token") as! String, forKey: "ZOHO_access")
                        print(json)
                        let access:String = ""//json.value(forKey: "access_token") as! String;
                        let ref:String = ""//json.value(forKey: "refresh_token") as! String

                        DispatchQueue.main.asyncAfter(deadline: .now() + 3.0, execute: {
                            self.displayAlert(appname: "ZOHO", accessToken: access, referenseToken: ref)
                        })
                    }
                } catch let error {
                    print(error.localizedDescription)
                }
            }
        })

        dataTask.resume()
}

响应:您可以在下面的响应中看到我没有获得刷新 token 。请帮助我如何获得刷新 token ？

{
    "access_token": "1000.2......",
    "expires_in_sec": 3600,
    "api_domain": "https://www.zohoapis.in",
    "token_type": "Bearer",
    "expires_in": 3600000
}

我遇到了同样的问题，但最终在 Mail API 的文档中找到了答案。要强制刷新 token ，您需要向初始 Post 添加两个附加参数:

access_type=offline&prompt=consent

这可确保您获得刷新 token 和访问 token 。
