阿里云OSS C#回调服务实例代码

先贴出客户端上传文件代码和毁掉函数的定义

需要的引用有：using Aliyun.OSS；

通过nuget包，获取aliyun.oss   dll

string url = "http://184.55.52.41:58123/api/Values/Put";
        string postData = "{\"bucket\":\"up01\",\"fileName\":\"2.jpg\",\"etag\":\"image\",\"size\":\"1024\",\"mimeType\":\"5\",\"my_var1\":\"6\",\"my_var2\":\"7\"}";

        private void btnUpOss_Click(object sender, EventArgs e)
        {
            //SampleUpload();
            //return;

            OssClient client = new OssClient("oss-cn-beijing.aliyuncs.com", accessKeyId, accessKeySecret);
            postData = "bucket=${bucket}&fileName=${object}&etag=${etag}&size=${size}&mimeType=${mimeType}&my_var1=${x:var1}&my_var2=${x:var2}";

            var metadata = BuildCallbackMetadata(url, postData);

            using (var fs = File.Open(textBox1.Text, FileMode.Open))
            {
                var putObjectRequest = new PutObjectRequest(bucketName, "huTest.jpg", fs, metadata);
                var result = client.PutObject(putObjectRequest);
                string responseContent = GetCallbackResponse(result);
                textBox1.Text = responseContent;
            }
        }

private ObjectMetadata BuildCallbackMetadata(string callbackUrl, string callbackBody)
        {
            string callbackHeaderBuilder = new CallbackHeaderBuilder(callbackUrl, callbackBody).Build();
            string CallbackVariableHeaderBuilder = new CallbackVariableHeaderBuilder().
                AddCallbackVariable("x:var1", "bidoStar").AddCallbackVariable("x:var2", "2017-09-19 15:35:12").Build();

            var metadata = new ObjectMetadata();
            metadata.AddHeader(HttpHeaders.Callback, callbackHeaderBuilder);
            metadata.AddHeader(HttpHeaders.CallbackVar, CallbackVariableHeaderBuilder);
            return metadata;
        }
        private string GetCallbackResponse(PutObjectResult putObjectResult)
        {
            string callbackResponse = null;
            using (var stream = putObjectResult.ResponseStream)
            {
                var buffer = new byte[4 * 1024];
                var bytesRead = stream.Read(buffer, 0, buffer.Length);
                callbackResponse = Encoding.Default.GetString(buffer, 0, bytesRead);
            }
            return callbackResponse;
        }

oss回调服务器的实例代码

以下代码暂时不包含签名等参数；后面会追加加密参数等【等待尝试后，后期更新代码】；

项目是webapi 写的接口；

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using WebApiOss.Common;
using Newtonsoft.Json;
using System.Text;

namespace WebApiOss.Controllers

    public class OSSController : ApiController
    {
        public string Get(string id,string name="pp")
        {
            Log4Helper.Info(name+"日志内容：" +id);
            return "id="+id;
        }

        public JsonModel Post([FromBody]CallBackModel body)
        {
            Log4Helper.Info("------FileCallBack------");
            Log4Helper.Info(body.bucket + " " + body.fileName + " " + body.etag + " " + body.size + " " + body.mimeType + " " + body.my_var1 + " " + body.my_var2 + "&var1:" + body.var1 + " var2:" + body.var2);
            return new JsonModel() { status = 200,msg=""};
            //return new HttpResponseMessage()
            //{
