Question

WKWebView可以访问https://example.com，但不能从Swift加载https://example.com/或https://example.com/subdir/file.html。第一个和第二个URL可以访问，但是第三个不能加载。而且它无法加载本地html文件。

import UIKit
import WebKit

class ViewController: UIViewController, WKNavigationDelegate {
    var webView: WKWebView!
    var progressView: UIProgressView!

    var websites = ["apple.com", "hackingwithswift.com", "www.apple.com/index.html"]

    override func loadView() {
        webView = WKWebView()
        webView.navigationDelegate = self
        view = webView
    }

    override func viewDidLoad() {
        super.viewDidLoad()

//        let url = Bundle.main.url(forResource: "publish", withExtension: "html", subdirectory: "website")!
        let url = URL(string: "http://" + websites[2])!
//        webView.loadFileURL(url, allowingReadAccessTo: url)
        webView.load(URLRequest(url: url))
        webView.allowsBackForwardNavigationGestures = true

我认为您的数组索引不正确。在您的viewDidload（）中进行如下更改：

uploadFile(lst: Array<any>): Observable<any>
    {
        var formData = new FormData();
        lst.forEach(item =>
        {
            formData.append('file', item.fILE);
            formData.append('att', JSON.stringify(item.att));
        });
        return this.http.Post("/UploadFile", formData);
    }

wkwebview无法访问某些URL
