使用WebView在iOS中进行Instagram集成失败 [英] Instagram integration fails in iOS by using webView

问题描述

在我的应用程序中，我正在使用webView进行Instagram身份验证.首先显示了Instagram登录屏幕，成功登录后，我正在获取accessToken，然后使用accessToken获取了其他详细信息.

In my application i was doing Instagram authentication using webView .first it was showing Instagram login screen ,after successfully login i was fetching accessToken then i fetched other details using the accessToken.

这是我在viewDidLoad中调用的loadrequest方法

here is my loadrequest method which i am calling in viewDidLoad

func loadrequest(){

        let authURL = String(format: "%@?client_id=%@&redirect_uri=%@&response_type=token&scope=%@", arguments: [INSTAGRAM_API.INSTAGRAM_AUTHURL,INSTAGRAM_API.INSTAGRAM_CLIENT_ID,INSTAGRAM_API.INSTAGRAM_REDIRECT_URI, INSTAGRAM_API.INSTAGRAM_SCOPE ])
        let urlRequest =  URLRequest.init(url: URL.init(string: authURL)!)
        instaWebview.loadRequest(urlRequest)

    }

这是我的webViewDelegate方法，我在其中调用checkRequestForcallBackURL方法

here is my webViewDelegate methods where i am calling checkRequestForcallBackURL method

  func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
       return checkRequestForcallBackURL(request: request)
    }

通过这种方法，我正在检查是否获取访问令牌

inthis method i am checking whether iam getting my accesstoken or not

   func checkRequestForcallBackURL(request : URLRequest) ->Bool{

            let requestURLString = (request.url?.absoluteString)! as String

            if requestURLString.hasPrefix(INSTAGRAM_API.INSTAGRAM_REDIRECT_URI) {
                let range: Range<String.Index> = requestURLString.range(of: "#access_token=")!

  handleAuth(authToken: requestURLString.substring(from: range.upperBound))
        return false;
    }

        return true
    }

现在，在登录时询问其安全代码时，在提供安全代码后，它将我重定向到我不想要的Instagram App.我不知道如何进一步进行操作

Now while login its asking security code ,after giving security code it redirects me to Instagram App which i don't want .I don't know how to proceed further

推荐答案

我在自己的应用程序中实现了Instagram登录.我是做什么的.要获取instagram令牌，只需提供带有Webview的新ViewController并加载instagram登录页面即可.

I implement Instagram login in one my application. What i do is. for getting instagram token simply present new ViewController with webview and load instagram login page.

let authURL = String(format: "%@?client_id=%@&redirect_uri=%@&response_type=token&scope=%@&DEBUG=True", arguments: [INSTAGRAM_IDS.INSTAGRAM_AUTHURL,INSTAGRAM_IDS.INSTAGRAM_CLIENT_ID,INSTAGRAM_IDS.INSTAGRAM_REDIRECT_URI, INSTAGRAM_IDS.INSTAGRAM_SCOPE ])
    let urlRequest =  URLRequest.init(url: URL.init(string: authURL)!)
    web_instaView.loadRequest(urlRequest)

然后使用webview委托方法

then in webview delegate method

func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
    return checkRequestForCallbackURL(request: request)
}


func checkRequestForCallbackURL(request: URLRequest) -> Bool {

    let requestURLString = (request.url?.absoluteString)! as String

    if requestURLString.hasPrefix(INSTAGRAM_IDS.INSTAGRAM_REDIRECT_URI) {
        let range: Range<String.Index> = requestURLString.range(of: "#access_token=")!
        handleAuth(authToken: requestURLString.substring(from: range.upperBound))
        return false;
    }
    return true
}

func handleAuth(authToken: String)  {
    print("Instagram authentication token ==", authToken)
    INSTAGRAM_IDS.INSTAGRAM_USER_TOCKEN = authToken
    UserDefaults.standard.setValue(INSTAGRAM_IDS.INSTAGRAM_USER_TOCKEN, forKey: "INSTAGRAM_USER_TOCKEN")
    NotificationCenter.default.post(name: NSNotification.Name("instaLoginDone"), object: nil)
    self.dismiss(animated: true, completion: nil)
}

获取instagram令牌后，我简单地关闭了ViewController并在本地保存Token.比在后台模式下获取用户信息，并显示加载程序或您想要的任何内容.

after getting instagram token, i simple dismiss that ViewController and save Token locally. Than fetch user info in background mode and show loader or whatever you want.
