"Original" I understand the Automatic Update-client update process

Creates an update thread that interacts with the UI main thread through a message.
1, go to http://version.mygame.com/check.php? Channelid=%d&appver=%d&resver=%d Gets the latest version information for the client. Use curl to get the code as follows, as for Curl's specific parameters, man or search engine will tell you the answer

1 Staticsize_t Funcgethttptext (void*ptr, size_t size, size_t nmemb,void*UserData) {2size_t retsize = size*Nmemb;3     string* Pcontent = (string*) UserData;4     if(pcontent) {5Pcontent->append ((Char*) ptr, retsize);6}returnretsize;7 }8Curlcode Gethttptext (Const string& strURL,string&Strhttptext) {9curl* PCurl =curl_easy_init ();Ten     if(!PCurl) { One         returnCurl_last; A     } - strhttptext.clear (); -Curl_easy_setopt (PCurl, Curlopt_connecttimeout, -); theCurl_easy_setopt (PCurl, Curlopt_nosignal,1); -Curl_easy_setopt (PCurl, Curlopt_forbid_reuse,1); -Curl_easy_setopt (PCurl, Curlopt_ssl_verifypeer,0L); - curl_easy_setopt (PCurl, Curlopt_url, Strurl.c_str ()); + curl_easy_setopt (PCurl, curlopt_writefunction, funcgethttptext); -Curl_easy_setopt (PCurl, Curlopt_writedata, &strhttptext); +Curlcode err =Curl_easy_perform (pCurl); A     if(Err = =CURLE_OK) { at         intSZ =0; -Curl_easy_getinfo (PCurl, Curlinfo_http_code, &sz); -         if(SZ! = $) && (sz! =206)) { -             //OK or not modify -Err =Curl_last; -         } in     } - Curl_easy_cleanup (pCurl); to     returnerr; +}

Resolves the returned string.
1: Large version of the update, Pop-up dialog box, prompting the need for a large version of the update, the user can choose "Update", "Cancel". After the cancellation, exit the app and click Update to enter the process below.
Android: Download the appropriate apk from the returned URL and reload it (reload only for app, not reset resources),
Ios:adhoc is updated by the way code opens the URL. The code is as follows

[[UIApplication sharedapplication] Openurl:[nsurl urlwithstring:@ "itms-services://?action= Download-manifest&url==https://raw.githubusercontent.com/xxxxxhttp.plist"];

AppStore: Then open the AppStore app for updates, the code is as follows

[[UIApplication sharedapplication] Openurl:[nsurl urlwithstring:@ ""];

This will jump out of the current app and go to the AppStore app details page.
2: The local resource version number is 0 and the initial package is downloaded. 3: Download diff package for local resource version >0
Determine whether the local downloaded temporary file size is the same as the size of the extranet file, and if it is not the same, the breakpoint downloads the external network file. Curl supports breakpoint download, the code is as follows

1 Char rangbuf[0  }; 2 " %d- " , nrangefrom); 3 curl_easy_setopt (PCurl, Curlopt_range, rangbuf);

In addition, the download needs to determine the 3g environment problem, if in the 3g environment, downloaded files more than a certain size (such as 30M), then prompts the player whether to download, the player chooses whether to download. Because we download modules that are multithreaded, the main thread and multithreading communicate through the mutex.
Download Thread:

1  while(1) {2This_thread::sleep_for (Chrono::milliseconds ( -));3Std::unique_lock<std::mutex>Locker (m_mtxconfirm);4    if(M_eupdateconfirm = =Updateimplconfirm::update_unknow) {5This_thread::yield();6}Else{7        Break;8    }9 }Ten if(m_eupdateconfirm = = Updateimplconfirm::update_reject) {//Reject Update OnePostMessage (Newuserrejectmessage (Updatestate::eupdatestatedownloadfile)); AM_eupdateconfirm =Updateimplconfirm::update_unknow; -     returnCurl_last; -}

Ui:

 1  void   Confirmcontinue () { 2  Std::lock_guard <std::mutex> Autolock (m_mtxconfirm);  3  m_eupdateconfirm = updateimplconfirm::update _continue;  4   5  void   Confirmreject () { 6  std::lock_guard<std::mutex> Autolock (m_mtxconfirm);  7  m_eupdateconfirm = updateimplconfirm::update _reject;  8 } 

After the download is complete, the file size and MD5 are compared, if different ... Delete the file and download it again.
After successful, unzip the file to the writable directory, read the index file for data parsing, copy the appended file, overwrite the file to the resource directory for overwriting, delete the file, then delete the corresponding file of the resource directory. Check the resources, traverse the local resource file for MD5 comparison, if not the same, then go to the extranet to download the scattered files for overwriting. Clean up the temp directory and delete the index file. The resource update is complete.
4. The resource version is greater than 0 and matches the server resource version without updating.
Other, error "Server timeout, return error, = =", display the "Retry" button to retry.
