19. 此时主资源的加载到此结束。

再来看看thirdparty/WebKit下的文件DocumentLoader.cpp中方法：

DocumentLoader::startLoadingMainResource()

我们之前分析的都是：该方法中的代码：

m_mainResource = m_fetcher->fetchMainResource(cachedResourceRequest, m_substituteData);

该方法中，之后有代码：m_mainResource->addClient(this);

10. 上面提到的代码执行的thirdparty/WebKIt下文件RawResource.cpp中方法：RawResource::appendData

该方法中有代码：

[cpp] view plain copy

while (RawResourceClient* c = w.next())
c->dataReceived(this, data, length);

这里执行的是DocumentLoader.cpp中方法：DocumentLoader::dataReceived

该方法中又会调用同文件中方法：DocumentLoader::commitData

9. 上面方法调用的是文件：thirdparty/WebKIt下文件ResourceLoader.cpp中方法：ResourceLoader::didReceiveData

该方法中有代码： m_resource->appendData(data, length);

8. 上面提到的代码调用的是 content目录下文件：web_url_loader_impl.cc中方法：

WebURLLoaderImpl::Context::OnReceivedData

该方法中有代码： client_->didReceiveData(loader_, data, data_length, encoded_data_length);

[cpp] view plain copy

while (RawResourceClient* c = w.next())
c->dataReceived(this, data, length);

这里执行的是DocumentLoader.cpp中方法：DocumentLoader::dataReceived

该方法中又会调用同文件中方法：DocumentLoader::commitData
