1、连接客户端时报错：MinIO API responded with message=No path allowed in endpoint 

1 2 3 4

MinioClient minioClient = new MinioClient("http://XXXX:9000",                                           accessKey:"Q3AM3UQ867SPQQA43P2F",                                           secretKey:"zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"                                           ).WithSSL();

　　

解决方法：把url的前缀http://去掉即可

2、报错MinIO API responded with message=Connection error: The SSL connection could not be established, see inner exception. The handshake failed due to an unexpected packet format.. Status code=0, response=The SSL connection could not be established, see inner exception. The handshake failed due to an unexpected packet format., content=)'

没有搭https的话，把连接语句的 WithSSL() 去掉即可

3、有个需求是从FTP服务里下载文件然后上传到MInIO，FTP使用了FluentFTP SDK，下载文件时直接new一个MempryStream来存储ftp文件的流，这样会导致上传到Minio的时候获取不到真正的文件size。

var stream = new MemoryStream() await ftpClient.DownloadAsync(stream, item.FullName);   await minioClient.PutObjectAsync("detection", item.Name, stream, stream.Length, "image/jpeg");

所以只能先获取字节数据，再转换成流，我也搞不懂为什么，基础知识太差了。。有大神知道的话麻烦回复一下

1 2 3 4 5

var byts= await ftpClient.DownloadAsync(item.FullName,0) using (MemoryStream br = new MemoryStream(byts))//初始化MemoryStream,并将Buffer指向FileStream的读取结果数组 {    await minioClient.PutObjectAsync("detection", item.Name, br, br.Length, "image/jpeg"); }

　

之后成功上传到Minio
