iOS wkwebview 网络请求

在iOS中，使用WKWebView进行网络请求有两种方法：使用默认的URL加载和使用自定义的URL加载。

1. 使用默认的URL加载：

import UIKit
import WebKit

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

    override func viewDidLoad() {
        super.viewDidLoad()

        let webViewConfiguration = WKWebViewConfiguration()
        webView = WKWebView(frame: view.bounds, configuration: webViewConfiguration)
        webView.navigationDelegate = self
        view.addSubview(webView)

        if let url = URL(string: "https://www.example.com") {
            let request = URLRequest(url: url)
            webView.load(request)
        }
    }

    // WKNavigationDelegate methods
    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        // 页面加载完成后的处理
    }

    func webView(_ webView: WKWebView, didFail navigation: WKNavigation!, withError error: Error) {
        // 页面加载失败时的处理
    }
}

2. 使用自定义的URL加载：

import UIKit
import WebKit

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

    override func viewDidLoad() {
        super.viewDidLoad()

        let webViewConfiguration = WKWebViewConfiguration()
        webView = WKWebView(frame: view.bounds, configuration: webViewConfiguration)
        webView.navigationDelegate = self
        view.addSubview(webView)

        let urlString = "https://www.example.com"
        let urlEncodedString = urlString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)
        if let url = URL(string: urlEncodedString ?? "") {
            let request = URLRequest(url: url)
            webView.load(request)
        }
    }

    // WKNavigationDelegate methods
    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        // 页面加载完成后的处理
    }

    func webView(_ webView: WKWebView, didFail navigation: WKNavigation!, withError error: Error) {
        // 页面加载失败时的处理
    }
}

这两种方法都需要在视图控制器中实现WKNavigationDelegate协议，并在适当的方法中处理页面加载成功和失败的情况
