请教一下百度网盘MD5的算法

百度网盘开放平台提供获取文件信息的接口，其中返回的md5值，与传统的MD5的结果不一致。
虽然结果都是32位，请问你知道百度网盘的md5是怎么算的吗？

遇到大文件时经常报错 downloadPart failed (unexpected)

想问一下，是不是被服务端限制了或禁止了？
是不是要开通VIP才能有更好的下载体验？
前面10个分片都能正常下载，从第11个分片开始就出错了。

error_msg":"app id is empty"

代码：
path := "/apps/go/Doc5.docx"
localFilePath := "/Users/cody/Downloads/Doc5.docx"
fileUploader := file.NewUploader(accessToken, path, localFilePath)
resp, err2 := fileUploader.Upload()
报错：
response[{"error_code":31024,"error_msg":"app id is empty","request_id"

想问下在哪填写回调地址

git tag版本号错误导致go无法获取最新的版本

作者你好，你的tag在0.0.9之后变成了.0.1.0，多了个点，这样go是无法获取到最新版的，只会获取到0.0.9，需要手动输入版本号才能导入

SuperFile2Upload fails with empty response on high concurrency

使用file.Uploader.Upload()时，我发现只要是几百MB及以上的文件100%失败，SuperFile2Upload返回空回复：

2023/04/07 13:32:14 upload failed, path[...] response[]
2023/04/07 13:32:14 SuperFile2UploadFailed, partseq[4] err[unexpected end of JSON input]
2023/04/07 13:32:14 strconv.Atoi failed, err: strconv.Atoi: parsing "": invalid syntax

把并发数调低之后就没问题了，1-3都行，别的没试：

diff --git a/file/upload.go b/file/upload.go
index 575f508..f787946 100644

+++ b/file/upload.go

 	uploadRespChan := make(chan SuperFile2UploadResponse, sliceNum)
-	sem := make(chan int, 10) //限制并发数，以防大文件上传导致占用服务器大量内存

 	for i := 0; i < sliceNum; i++ {
 		buffer := make([]byte, sliceSize)
 		n, err := file.Read(buffer[:])

第一次用百度网盘的API，也不知道是不是常见问题，反正记录一下方便遇到同样问题的朋友。我个人使用其实2并发也能完全占满上传带宽。

作者你好，第一次使用百度网盘API，想咨询一下

我的软件是桌面EXE，我只是想某些数据获取后备份一下在百度网盘，

然而我不知道桌面应用应该如何获取Access Token

我观察auth_accesstoken.go案例 但是参数需要一个code，开放者平台并没有提供

请问有打包好的方法吗？我只是希望自动把文件存到我个人的网盘即可

[optimize] 分片上传建议限制 goroutine 数量，上传大文件时会占用大量内存

	file, err := os.Open(u.LocalFilePath)
	if err != nil {
		return ret, err
	}
	defer file.Close()
	uploadRespChan := make(chan SuperFile2UploadResponse)
	for i := 0; i < sliceNum; i++ {
		buffer := make([]byte, sliceSize)
		n, err := file.Read(buffer[:])
		if err != nil && err != io.EOF {
			log.Println("file.Read failed, err:", err)
			return ret, err
		}
		if n == 0 {
			break
		}
                // 如果分片数量过多，这里会开大量 goroutine 进行上传，导致瞬间占用内存巨大
		go func(partSeq int, partByte []byte) {
			uploadResp, err := u.SuperFile2Upload(uploadID, partSeq, partByte)
			uploadRespChan <- uploadResp
			if err != nil {
				log.Printf("SuperFile2UploadFailed, partseq[%d] err[%v]", partSeq, err)
			}
		}(i, buffer[0:n])
	}
