逻辑或许跟这个差不多：
如果 githubURL 无法访问或下载速度较慢，则尝试使用 ghproxyURL 来加速访问 GitHub 上的资源
siyuan/kernel/model/updater.go
Lines 138 to 151 in 687421f
| b3logURL := "https://release.b3log.org/siyuan/" + pkg | |
| liuyunURL := "https://release.liuyun.io/siyuan/" + pkg | |
| githubURL := "https://github.com/siyuan-note/siyuan/releases/download/v" + ver + "/" + pkg | |
| ghproxyURL := "https://mirror.ghproxy.com/" + githubURL | |
| if util.IsChinaCloud() { | |
| downloadPkgURLs = append(downloadPkgURLs, b3logURL) | |
| downloadPkgURLs = append(downloadPkgURLs, liuyunURL) | |
| downloadPkgURLs = append(downloadPkgURLs, ghproxyURL) | |
| downloadPkgURLs = append(downloadPkgURLs, githubURL) | |
| } else { | |
| downloadPkgURLs = append(downloadPkgURLs, githubURL) | |
| downloadPkgURLs = append(downloadPkgURLs, b3logURL) | |
| downloadPkgURLs = append(downloadPkgURLs, liuyunURL) | |
| } |
相关的函数好像是这个：
siyuan/kernel/bazaar/package.go
Lines 549 to 585 in 687421f
| func downloadPackage(repoURLHash string, pushProgress bool, systemID string) (data []byte, err error) { | |
| packageLocksLock.Lock() | |
| defer packageLocksLock.Unlock() | |
| // repoURLHash: https://github.com/88250/Comfortably-Numb@6286912c381ef3f83e455d06ba4d369c498238dc | |
| repoURL := repoURLHash[:strings.LastIndex(repoURLHash, "@")] | |
| lock, ok := packageLocks[repoURLHash] | |
| if !ok { | |
| lock = &sync.Mutex{} | |
| packageLocks[repoURLHash] = lock | |
| } | |
| lock.Lock() | |
| defer lock.Unlock() | |
| repoURLHash = strings.TrimPrefix(repoURLHash, "https://github.com/") | |
| u := util.BazaarOSSServer + "/package/" + repoURLHash | |
| buf := &bytes.Buffer{} | |
| resp, err := httpclient.NewCloudFileRequest2m().SetOutput(buf).SetDownloadCallback(func(info req.DownloadInfo) { | |
| if pushProgress { | |
| progress := float32(info.DownloadedSize) / float32(info.Response.ContentLength) | |
| //logging.LogDebugf("downloading bazaar package [%f]", progress) | |
| util.PushDownloadProgress(repoURL, progress) | |
| } | |
| }).Get(u) | |
| if nil != err { | |
| logging.LogErrorf("get bazaar package [%s] failed: %s", u, err) | |
| return nil, errors.New("get bazaar package failed, please check your network") | |
| } | |
| if 200 != resp.StatusCode { | |
| logging.LogErrorf("get bazaar package [%s] failed: %d", u, resp.StatusCode) | |
| return nil, errors.New("get bazaar package failed: " + resp.Status) | |
| } | |
| data = buf.Bytes() | |
| go incPackageDownloads(repoURLHash, systemID) | |
| return | |
| } |

链滴数据中心默认就是用的国内七牛云，并且加了 CDN。
