如何快速在 iOS 的全局请求中添加 HTTP 标头 [英] How to add HTTP headers in request globally for iOS in swift

问题描述

func webView(webView: WKWebView!, decidePolicyForNavigationAction navigationAction: WKNavigationAction!, decisionHandler: ((WKNavigationActionPolicy) -> Void)!) {
     var request = NSMutableURLRequest(URL: navigationAction.request.URL)
     request.setValue("value", forHTTPHeaderField: "key")
     decisionHandler(.Allow)
}

在上面的代码中，我想向请求添加一个标头.我试过 navigationAction.request.setValue("IOS", forKey: "DEVICE_APP") 但它不起作用.

In the above code I want to add a header to the request. I have tried to do navigationAction.request.setValue("IOS", forKey: "DEVICE_APP") but it doesn't work.

请以任何方式帮助我.

推荐答案

AFAIK 遗憾的是你不能用 WKWebView 做到这一点.

AFAIK sadly you cannot do this with WKWebView.

它肯定在 webView:decidePolicyForNavigationAction:decisionHandler: 中不起作用，因为 navigationAction.request 是只读的并且是非可变的 NSURLRequest代码> 不能更改的实例.

It most certainly does not work in webView:decidePolicyForNavigationAction:decisionHandler: because the navigationAction.request is read-only and a non-mutable NSURLRequest instance that you cannot change.

如果我理解正确，WKWebView 在单独的内容和网络进程中运行沙盒，至少在 iOS 上，没有办法拦截或更改它的网络请求.

If I understand correctly, WKWebView runs sandboxed in a separate content and network process and, at least on iOS, there is no way to intercept or change it's network requests.

如果您退回到 UIWebView，您可以执行此操作.

You can do this if you step back to UIWebView.
