aws s3 使用webapi上传文件

前言：最近使用紫光云的OSS存储图片，他们使用aws s3存储的图片，给我的文档很难读懂.网上翻阅资料，实现webapi上传文件

1.下载Amazon提供的sdk

2.实现代码

using Amazon.S3;
using Amazon.S3.Model;
using System;
using System.Web;
namespace OSS{
     

 public class OSSUploadTest
 {
/// <summary>
/// 桶名称
/// </summary>
private const string bucketName = "****";
private static string accessKey = System.Configuration.ConfigurationManager.AppSettings["AWSAccessKey"];
private static string secretKey = System.Configuration.ConfigurationManager.AppSettings["AWSSecretKey"];
/// <summary>
        /// 文件上传
        /// </summary>
        /// <param name="file">文件</param>
        /// <param name="folder">文件夹</param>
        /// <returns></returns>
public bool UploadFile(HttpPostedFileBase file, string folder)
        {
            try
            {
                var config = new AmazonS3Config()
                {
                    ServiceURL = "http://***.unicloudsrv.com/"
                };
                using (AmazonS3Client client = new AmazonS3Client(
                    accessKey,
                    secretKey,
                    config
                ))
                {
                    var stream = file.InputStream;
                    string name = folder + "/" + file.FileName;
                    var putObjectRequest = new PutObjectRequest
                    {
                        BucketName = bucketName,
                        Timeout = TimeSpan.FromSeconds(5),
                        InputStream = stream,
                        Key = name,
                        CannedACL = S3CannedACL.PublicRead,
                        StorageClass = S3StorageClass.Standard,
                        ServerSideEncryptionMethod = ServerSideEncryptionMethod.None,
                    };
                    var data = client.PutObject(putObjectRequest);
                    if (data.HttpStatusCode == System.Net.HttpStatusCode.OK)
                    {
                        return true;
                    }
                    return false;
                }
            }
            catch (Exception exception)
            {
                Console.WriteLine(exception);
                return false;
            }
        }
    }
 }

其中：

bucketName 是桶名称

ServiceURL 是Endpoint

accessKey 是  AccessKey ID

secretKey 是  AccessKey Secret

 AccessKey ID和AccessKey Secret是您访问紫光云API的密钥，在控制台查看（配置在web.config中）

3.控制器

/// <summary>

/// 上传图片

/// </summary>

/// <returns></returns>

[HttpPost]

[Route("v3/uploads")]

public IHttpActionResult Uploads()

{

    var id = "123";

    HttpPostedFile file = HttpContext.Current.Request.Files["file"];

    if (string.IsNullOrEmpty(id))

    {

        return Json(false);

    }

    string type = "receipt";

    var folder = $"{type}/{id}";

    var data = new OSSUploadTest().UploadFile(new HttpPostedFileWrapper(file) as HttpPostedFileBase, folder);

    return Json(data);
