Question

我的任务是将Objective-C应用程序转换为完全Swift 4.该应用程序基本上是一个包装我的公司网站的webbroswer。为了让用户每次都抱怨输入用户名/密码，应用程序需要检查提交HTML表单的时间并抓取网站并存储u / p。

在ObjC中有一种方法： - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType

这让我可以检查表单的提交时间：

static NSString * const FORM_USER = @"document.getElementById('sUserID').value";
static NSString * const FORM_PASS = @"document.getElementById('sPassword').value";

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {

        //save form data
        if(navigationType == UIWebViewNavigationTypeFormSubmitted) {
            dispatch_async(dispatch_get_main_queue(), ^{
                //grab the data from the page
                NSString *username = [self.webView stringByEvaluatingJavaScriptFromString: FORM_USER];
                NSString *password = [self.webView stringByEvaluatingJavaScriptFromString: FORM_PASS];

                //store values locally in the background
                //.....
            });

        }
        return true;
    }

但我无法转换Swift 4.1，因为我似乎无法为WKWebView找到任何类型的UIWebViewNavigationTypeFormSubmitted。

有任何帮助吗？

let FORM_USER = "document.getElementById('sUserID').value"
let FORM_PASS = "document.getElementById('sPassword').value"

func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation) {

    if(webView.url == API_LOGIN_URL){

        if(WHAT A DO I CHECK FOR here?){

            //Grab IN LOGIN DETAILS
            var name = webView.evaluateJavaScript("\(FORM_USER)", completionHandler: nil)
            var pass = webView.evaluateJavaScript("\(FORM_PASS)", completionHandler: nil)

            //store values locally
            //...
        }

    }
}

Answer 1

应该是

if navigationType == UIWebViewNavigationType.formSubmitted

或

if navigationType == .formSubmitted

WKWebView检查HTML表单提交
