Functions ¶
func GetFileContent ¶ added in v1.2.42
func GetFileContentString ¶ added in v1.2.42
func GetFileHeaderMd5Name ¶
func GetFileHeaderMd5Name(fileHeader *multipart.FileHeader) (string, error)
func MergeChunk ¶ added in v1.2.37
func MergeChunk(url string, fileMergeReq *FileMergeReq) (*gohttp.Response, error)
分片全部上传完毕后,再请求文件分片合并请求(作为客户端请求时验证非法请求认证逻辑需要加,如authToken sign 等等)
func RemoveFile ¶
func SaveToLocal ¶ added in v1.2.37
//////////////////////////////////////////////////////////////local save 把分片存在指定目录
func UploadChunk ¶ added in v1.2.34
////////////////////////////////////////////////////////////// http server upload and merge 供参考 上传一个文件分片,(作为客户端请求时验证非法请求认证逻辑需要加,如authToken sign 等等)
Types ¶
type BigFile ¶ added in v1.2.34
type BigFile struct { ChunkSize int64 // 分片大小 M MaxWorkers int // 同时处理最大分块数量,合理用防止超大文件内存益处 File string // 文件路径 FileMd5 string // 文件Md5 ChunkCount int64 // 分片数量 FileChunkCallback func(chunk *FileChunk) error // 分片处理消息 SuccessChunkIndexes []int64 //处理成功的碎片index // contains filtered or unexported fields }
type FileChunk ¶ added in v1.2.34
type FileChunk struct { Data []byte //分片数据 Hash string //分片Hash Index int64 //分片顺序号 OriginalFileName string //原文件名 OriginalFileMd5 string //原文件Md5 FileName string //分片文件名称 }
fmt.Sprintf("%s.part%d", fileName, i) mapreduce big file 大文件逻辑 for 把大文件并发分片处理,为了防止OOM超大文件边分片边处理的策略
type FileMergeReq ¶ added in v1.2.37
type FileReceiveResult ¶ added in v1.2.37
func MergeFileForChunks ¶ added in v1.2.37
func MergeFileForChunks(filePath string, fileName string, fileMd5 string, totalChunks int64, isNotRemoveChunk bool) (*FileReceiveResult, error)
服务器合并所有文件分片,并验证md5, isNotRemoveChunk =true 合并后时不会删除分片
func ReceiveChunkHandler ¶ added in v1.2.34
func ReceiveChunkHandler(assetsDir string, chunkIndex int64, chunkMd5 string, fileMd5 string, file *multipart.FileHeader) (*FileReceiveResult, error)
服务器接受文件分片
func ReceiveFile ¶ added in v1.2.34
func ReceiveFile(assetsDir string, file *multipart.FileHeader) (*FileReceiveResult, error)
服务器接受file文件到assetsDir目录下,assetsDir 目录不存在则自动创建,返回存储位置
