网上关于CEF3读取加密资源的中文资料特别少~，所以我就来写一篇教程吧
实际应用： PC版的“网易云音乐”就是把H5资源加密成zip文件，启动时动态读取。
原理:
让自己的MyClientHandler来继承 CefRequestHandler这个抽象类，然对其下面的纯虚函数进行重写
simple_handler.h：
-
-
class SimpleHandler : public CefClient,
-
public CefDisplayHandler,
-
public CefLifeSpanHandler,
-
public CefRequestHandler{
-
-
virtual CefRefPtr<CefRequestHandler> GetRequestHandler() OVERRIDE { return this; }
-
-
// CefRequestHandler methods:
-
virtual cef_return_value_t OnBeforeResourceLoad(
-
CefRefPtr<CefBrowser> browser,
-
CefRefPtr<CefFrame> frame,
-
CefRefPtr<CefRequest> request,
-
CefRefPtr<CefRequestCallback> callback) OVERRIDE;
-
virtual CefRefPtr<CefResourceHandler> GetResourceHandler(
-
CefRefPtr<CefBrowser> browser,
-
CefRefPtr<CefFrame> frame,
-
CefRefPtr<CefRequest> request) OVERRIDE;
-
-
private:
-
// Manages the registration and delivery of resources.
-
CefRefPtr<CefResourceManager> resource_manager_;
simple_handler.cc：
-
-
-
-
namespace {
-
-
SimpleHandler* g_instance = NULL;
-
-
} // namespace
-
-
-
-
// Demonstrate a custom Provider implementation by dumping the request contents.
-
class RequestDumpResourceProvider : public CefResourceManager::Provider {
-
public:
-
explicit RequestDumpResourceProvider(const std::string& url) : url_(url) {
-
DCHECK(!url.empty());
-
}
-
-
bool OnRequest(scoped_refptr<CefResourceManager::Request> request) OVERRIDE
-
{
-
CEF_REQUIRE_IO_THREAD();
-
-
const std::string& url = request->url();
-
if (url != url_)
-
{
-
// Not handled by this provider.
-
return false;
-
}
-
-
//const std::string& dump = shared::DumpRequestContents(request->request());
-
std::string str =
-
//"<html><body bgcolor="white"><pre>" + dump + "</pre></body></html>";
-
"<html><body bgcolor="white"><pre>123123123123</pre></body></html>";
-
CefRefPtr<CefStreamReader> stream = CefStreamReader::CreateForData(
-
static_cast<void*>(const_cast<char*>(str.c_str())), str.size());
-
DCHECK(stream.get());
-
request->Continue(new CefStreamResourceHandler("text/html", stream));
-
return true;
-
}
-
-
private:
-
std::string url_;
-
-
DISALLOW_COPY_AND_ASSIGN(RequestDumpResourceProvider);
-
};
-
-
// Add example Providers to the CefResourceManager.
-
void SetupResourceManager(CefRefPtr<CefResourceManager> resource_manager)
-
{
-
if (!CefCurrentlyOn(TID_IO))
-
{
-
// Execute on the browser IO thread.
-
CefPostTask(TID_IO, base::Bind(SetupResourceManager, resource_manager));
-
return;
-
}
-
-
// Add the Provider for dumping request contents.
-
resource_manager->AddProvider(
-
new RequestDumpResourceProvider("http://www.baidu.com/"), 0,
-
std::string());
-
}
-
-
-
-
SimpleHandler::SimpleHandler(bool use_views)
-
: use_views_(use_views), is_closing_(false) {
-
DCHECK(!g_instance);
-
g_instance = this;
-
-
//安装资源管理器
-
resource_manager_ = new CefResourceManager();
-
SetupResourceManager(resource_manager_);
-
}
至此，打开http://www.baidu.com，都会被拦截下来，显示123123123123
