注意:如果有多个项目,需要在具体使用的项目跟启动项目都安装同一版本的Aliyun.OSS.SDK
using Aliyun.OSS;
using System.IO;
using System;
using CadApplication.Service.Dto;

string bucketName = "*******"; // 设置自己的 Bucket Name annengcadapitest

{
// 整体逻辑:上传服务器本地文件到阿里云OSS,然后上传成功后再获取OSS文件的存放路径
CommonResult<OSSFileInforDto> result = new CommonResult<OSSFileInforDto>();
// 创建 OssClient 对象
var ossClient = new OssClient("*******.aliyuncs.com", "*******", "*******");
// 获取本地文件路径
string localFilePath = @"C:\Users\*******\Desktop\MonthQuery.txt"; // 设置本地文件路径
// 指定上传到 OSS 的目标文件名称
string fileName = Path.GetFileName(localFilePath);
// OSS的路径 规律 年/月/日 例如:2024/1/20240101

string objectName = filePath +"/"+ fileName;
try
{
using (var fs = File.OpenRead(localFilePath))
{
// 调用 PutObjectAsync 方法进行文件上传
var putResult= ossClient.PutObject(bucketName, objectName, fs);
// 说明文件上传成功,然后读取到文件的存放地址,进行返回
if (putResult.HttpStatusCode == HttpStatusCode.OK)

foreach (IPAddress ip in host.AddressList)

}
// 然后返回数据的url
OSSFileInforDto oSSFileInforDto = new OSSFileInforDto();

}
catch (Exception ex)

finally

// ossClient.shutdown;
}
return result;
}
}
}
引起这个问题由两个原因:1. 启动项目里面没有安装【Aliyun.OSS.SDK】。2.启动项目里面的【Aliyun.OSS.SDK】跟实际执行代码的项目里面的【Aliyun.OSS.SDK】版本不一致。
没有在OSS上创建Bucket(桶),使用阿里云官方工具OSS Browser 创建,也可以使用代码创建。具体可以参考阿里云官方文档:https://help.aliyun.com/zh/oss/getting-started/sdk-quick-start?spm=a2c4g.11186623.0.0.1db27586JIsQcM
