一、选项页安全dns选项如下图:
二、那么如何自定义安全dns功能呢?
1、先看前端部分代码调用
shared.rollup.js
class PrivacyPageBrowserProxyImpl {
.................................................................
getSecureDnsResolverList() {
return sendWithPromise("getSecureDnsResolverList") //获取dns列表
}
getSecureDnsSetting() {
return sendWithPromise("getSecureDnsSetting")
}
isValidConfig(entry) {
return sendWithPromise("isValidConfig", entry) //检测dns是否正确
}
probeConfig(entry) {
return sendWithPromise("probeConfig", entry)
}
static getInstance() {
return instance$g || (instance$g = new PrivacyPageBrowserProxyImpl)
}
static setInstance(obj) {
instance$g = obj
}
}
2、看c++代码对应的注册函数
chrome\browser\ui\webui\settings\settings_secure_dns_handler.cc
void SecureDnsHandler::RegisterMessages() {
web_ui()->RegisterMessageCallback(
"getSecureDnsResolverList",
base::BindRepeating(&SecureDnsHandler::HandleGetSecureDnsResolverList,
base::Unretained(this)));
web_ui()->RegisterMessageCallback(
"getSecureDnsSetting",
base::BindRepeating(&SecureDnsHandler::HandleGetSecureDnsSetting,
base::Unretained(this)));
web_ui()->RegisterMessageCallback(
"isValidConfig",
base::BindRepeating(&SecureDnsHandler::HandleIsValidConfig,
base::Unretained(this)));
web_ui()->RegisterMessageCallback(
"probeConfig", base::BindRepeating(&SecureDnsHandler::HandleProbeConfig,
base::Unretained(this)));
web_ui()->RegisterMessageCallback(
"recordUserDropdownInteraction",
base::BindRepeating(
&SecureDnsHandler::HandleRecordUserDropdownInteraction,
base::Unretained(this)));
}
1、先看 前端"getSecureDnsResolverList "dns列表对应c+++获取函数
base::Value::List SecureDnsHandler::GetSecureDnsResolverList() {
base::Value::List resolvers;
// Add a custom option to the front of the list
base::Value::Dict custom;
custom.Set("name", l10n_util::GetStringUTF8(IDS_SETTINGS_CUSTOM));
custom.Set("value", std::string()); // Empty value means custom.
custom.Set("policy", std::string());
resolvers.Append(std::move(custom));
//providers_ 是dns数据列表来源,定义参考下面介绍
for (const auto* entry : providers_) {
net::DnsOverHttpsConfig doh_config({entry->doh_server_config});
base::Value::Dict dict;
dict.Set("name", entry->ui_name);
dict.Set("value", doh_config.ToString());
dict.Set("policy", entry->privacy_policy);
resolvers.Append(std::move(dict));
}
// Randomize the order of the resolvers, but keep custom in first place.
base::RandomShuffle(std::next(resolvers.begin()), resolvers.end());
return resolvers;
}
2、重点看providers_函数 ,其赋值和定义看代码:
chrome\browser\ui\webui\settings\settings_secure_dns_handler.h
static net::DohProviderEntry::List GetFilteredProviders();
net::DohProviderEntry::List providers_ = GetFilteredProviders();
std::unique_ptr<chrome_browser_net::DnsProbeRunner> runner_;
chrome_browser_net::DnsProbeRunner::NetworkContextGetter
network_context_getter_ =
base::BindRepeating(&SecureDnsHandler::GetNetworkContext,
base::Unretained(this));
// static
net::DohProviderEntry::List SecureDnsHandler::GetFilteredProviders() {
return secure_dns::ProvidersForCountry(
secure_dns::SelectEnabledProviders(net::DohProviderEntry::GetList()),
country_codes::GetCurrentCountryID());
}
providers_ 通过GetFilteredProviders()获取列表
3、最后看列表定义net::DohProviderEntry::GetList()
net\dns\public\doh_provider_entry.cc
const DohProviderEntry::List& DohProviderEntry::GetList() {
// See /net/docs/adding_doh_providers.md for instructions on modifying this
// DoH provider list.
//
// The provider names in these entries should be kept in sync with the
// DohProviderId histogram suffix list in
// tools/metrics/histograms/metadata/histogram_suffixes_list.xml.
static const base::NoDestructor<DohProviderEntry::List> providers{{

三、至此数据来源分析完毕,如果想要用自己的dns只需要在
net\dns\public\doh_provider_entry.cc
const DohProviderEntry::List& DohProviderEntry::GetList() 函数里面按照此格式追加即可。
不同版本内核的浏览器有所差异。
