向 WebView 资源请求添加自定义标头 - android [英] Add custom headers to WebView resource requests - android

问题描述

我需要向来自 WebView 的每个请求添加自定义标头.我知道 loadURL 有 extraHeaders 的参数，但这些只适用于初始请求.所有后续请求都不包含标头.我查看了 WebViewClient 中的所有覆盖，但没有任何内容允许向资源请求添加标头 - onLoadResource(WebView view, String url).任何帮助都会很棒.

I need to add custom headers to EVERY request coming from the WebView. I know loadURL has the parameter for extraHeaders, but those are only applied to the initial request. All subsequent requests do not contain the headers. I have looked at all overrides in WebViewClient, but nothing allows for adding headers to resource requests - onLoadResource(WebView view, String url). Any help would be wonderful.

谢谢，雷

推荐答案

尝试

loadUrl(String url, Map<String, String> extraHeaders)

要向资源加载请求添加标头，请自定义 WebViewClient 并覆盖:

For adding headers to resources loading requests, make custom WebViewClient and override:

API 24+:
WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request)
or
WebResourceResponse shouldInterceptRequest(WebView view, String url)
