我正在开发一个Android应用程序,使用白名单过滤请求并使用自定义SSLSocketFactory
。为此,我开发了一个自定义的WebViewClient
并覆盖了shouldInterceptRequest
方法。我可以过滤和使用我的SocketFactory
处理GET请求,但我无法拦截POST请求。
那么,在WebView
中是否有一种方式可以拦截POST请求?
以下是shouldInterceptRequest
方法的代码:
public final WebResourceResponse shouldInterceptRequest(WebView view, String urlStr) {
URI uri = URI.create(urlStr);
String scheme = uri.getScheme();
// If scheme not http(s), let the default webview manage it
if(!"http".equals(scheme) && !"https".equals(scheme)) {
return null;
}
URL url = uri.toURL();
if(doCancelRequest(url)) {
// Empty response
Log.d(TAG, "URL filtered: " + url);
return new WebResourceResponse("text/plain", "UTF-8", new EmptyInputStream());
} else {
Log.d(TAG, "URL: " + url);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestProperty("User-Agent", mSettings.getUserAgentString());
// Configure connections
configureConnection(conn);
String mimeType = conn.getContentType();
String encoding = conn.getContentEncoding();
if(mimeType != null && mimeType.contains(CONTENT_TYPE_SPLIT)) {
String[] split = mimeType.split(CONTENT_TYPE_SPLIT);
mimeType = split[0];
Matcher matcher = CONTENT_TYPE_PATTERN.matcher(split[1]);
if(matcher.find()) {
encoding = matcher.group(1);
}
}
InputStream is = conn.getInputStream();
return new WebResourceResponse(mimeType, encoding, is);
}
}
