Question

我是ios，swift和Xcode的新手。

我有一个onClick的组件。我想在WKWebView时添加一些标题，以便重定向到Android中的另一个页面。如何覆盖或添加标题？如果在webView.setWebViewClient(new WebViewClient() { : @Override public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest url) { if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { view.loadUrl(url.getUrl().toString(), extraHeader); } return true; } : @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.N) { view.loadUrl(url, extraHeader); } return true; } : }版本中，我可以这样做：

override func viewDidLoad() {

        super.viewDidLoad()

        // Do any additional setup after loading the view, typically from a nib.


        let url = URL(string: BASE_URL)

        let request = NSMutableURLRequest(url: url!)

        request.addValue(MOBILE, forHTTPHeaderField: X_CLIENT_TYPE)



        self.webView.load(request as URLRequest)

 }

我已经这样做了：

WKWebView

但是，上面的代码仅用于首次加载。如果我点击a = ["Isolated-1", "SVT_FedPortGroup", "SVT_StoragePortGroup", "VM Network", "test-pg-2002"] b = ["target_Isolated-1", "target_SVT_FedPortGroup", "target_SVT_StoragePortGroup", "target_VM Network", "target_test-pg-2002"] c = { "NetworkMaps": [] } for (var i = 0; i < a.length; i++) { c.NetworkMaps.push({ "ENVID": null, "SourcePG": a[i], "TargetPG": b[i] }) } console.log(c);中的链接，标题就会消失。

所以，我很高兴有人能帮助我......

Answer 1

var request = URLRequest(url: URL(string: url)!)
request.httpMethod = "POST"
// If you have post parameter pass here 
let postString = "key=\(Value!)&Key=\(Value!)"
request.httpBody = postString.data(using: .utf8)

// Set your Header here   
request.setValue("MOBILE", forHTTPHeaderField:"X_CLIENT_TYPE")

 if request != nil
    {
        webView.loadRequest(request)
        webView.delegate = self     
    }

你可以做二次点击

func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType:
    UIWebViewNavigationType) -> Bool
{
    var Myrequest  = URLRequest.init(url: request.url!)

    Myrequest.setValue("MOBILE", forHTTPHeaderField:"X_CLIENT_TYPE")

    webView.loadRequest(Myrequest)

    true
}

我已经找到了解决方案：

func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {

        print("decidePolicyFor")

        let request = navigationAction.request

        print("request: ", request)



        if ( (request.url?.absoluteString.hasPrefix(BASE_URL))! && request is NSMutableURLRequest) {

            print("NSMutableURLRequest")

            let mutableRequest = request as! NSMutableURLRequest;

            let clientType = mutableRequest.value(forHTTPHeaderField: X_CLIENT_TYPE) as String?

            print("clientType: ", clientType)



            if (clientType != nil && clientType == MOBILE) {

                print("client type is MOBILE")

            } else {

                print("add client type MOBILE")

                mutableRequest.addValue(MOBILE, forHTTPHeaderField: X_CLIENT_TYPE)

                webView.load(mutableRequest as URLRequest)

            }

            decisionHandler(WKNavigationActionPolicy.allow)

        } else {

            print("NOT NSMutableURLRequest")



            decisionHandler(WKNavigationActionPolicy.allow)

        }

    }
