Before subprocess access URL, need to tackle on suitable opportunity, obtain this url, current inner sign (and corresponding parameter, corresponding parameter can refer to that webpage opens request type and POST parameter), and send the willNavigate event to host process, allow host process remove to judge whether to need the switching kernel.When current operation kernel is the trident kernel, obtain url and corresponding parameter in the BeforeNavigate event.When current operation kernel is the webkit kernel, obtain url and corresponding parameter in the willSendRequest event.No matter and current operation kernel is trident kernel or webkit kernel, the current inner sign all can directly obtain.
In this step, described subprocess can send to host process by the willNavigate event with url, the current inner sign (and corresponding parameter) determined.
Host process is processed the willNavigate event, according to url, need to judge whether the switching kernel.Concrete, when host process is processed, can check at first whether url is distinctive url, as bluesky: //the built-in page of this browser of newtab must use the WebKit kernel to play up (also can be understood as and judge whether url is that the needs of preserving in the first configuration file use the WebKit kernel to process the url list).Then check url by configuration file (can be understood as the second configuration file), preserve in configuration file and need to use the trident kernel to process the url list, if this url is in this list, expression needs to use the trident kernel to process.
Can allow another kernel (non-current operation kernel) access this url when needs switch, and Returning mark indicates it for described subprocess to be to continue access, still to stop immediately.Concrete, can will indicate described subprocess to continue to access the result that still stops immediately by the outlet parameter of willNavigate and return to described subprocess.And this outlet parameter can be set when not needing to switch be true (true), indicate described subprocess to continue to access.Otherwise it is false (false) that this outlet parameter is set, and indicates described subprocess to stop access.
Described subprocess is waited for the result of host process, and checks the outlet parameter of willNavigate event, if this outlet parameter be true continue to carry out, otherwise stop this request.Concrete, when current operation kernel is the webkit kernel, the rreturn value that described subprocess can be given amended willSendRequest event functions with the value of willNavigate event outlet parameter, and all call flows of modification willSendRequest event functions, the rreturn value of judgement willSendRequest event functions, be that true continues access in rreturn value, otherwise stop access immediately.When current operation kernel is the trident kernel, described subprocess can directly be given the value of willNavigate event outlet parameter the outlet parameter (can represent with continue) of BeforeNavigate event functions, described subprocess can be that true continues access at continue, otherwise stops access immediately.
In this step, except indicating current operation kernel whether to continue to carry out the operation of opening webpage, if need the switching kernel, allow another kernel (non-current operation kernel) access this url, in this step, can also produce a new subprocess (also can find a subprocess that is using the target kernel) that uses the target kernel, url, webpage are opened request type and the post parameter passes to this new subprocess, new subprocess uses these parameters to conduct interviews, and shows webpage corresponding to described url.
The scheme that provides according to the embodiment of the present application one ~ embodiment eight, the url that can utilize the subprocess based on current operation kernel to provide to host process before accessed web page, determined to open the target kernel of webpage corresponding to this url by host process, and utilize subprocess corresponding to target kernel of determining to open webpage.When making the performance that can utilize kernel main in the multinuclear browser to open webpage to guarantee web browser, stability and security, can also be when the kernel that utilizes ensure compatibility be opened webpage, reduce the network traffics waste, accelerate this kernel and open the speed of webpage, and eliminate the problem that repeats to open the page flicker that causes due to webpage.The scheme that the embodiment of the present application provides is particularly useful in the general website without online transaction, the WebKit kernel access (so-called " fast mode ") that operating speed is fast, in access Alipay or Web bank, use " compatibility mode " of Trident kernel to carry out in the double-core browser application scene of business.
