本文介绍了一个使用 C# 实现的异步任务方法，用于创建指定项目的日志存储。该方法通过构造 HTTP 请求并发送到指定的日志服务端点来实现。

public async Task<bool> CreateLogStore(string project, string logStore)
        {
            using (var client = new HttpClient())
            {
                var time = DateTime.Now;
                string body = Newtonsoft.Json.JsonConvert.SerializeObject(new LogBody() { logstoreName = logStore, ttl = 1, shardCount = 2 });
                string date = FormatRfc822Date(time);

                string contentMD5 = MD5Encrypt(body);
                string signString = Sign("POST\n" + contentMD5 + "\napplication/json\n" + date + "\nx-log-apiversion:0.6.0\nx-log-signaturemethod:hmac-sha1\n/logstores", this.accessKeySecret);

                HttpContent content = new StringContent(body);
                string sign = string.Format("{0}:{1}", accessKeyId, signString);

                client.DefaultRequestHeaders.Add("x-log-apiversion", "0.6.0");
                client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("LOG", sign);
                client.DefaultRequestHeaders.Add("host", project + "." + endpoint);
                client.DefaultRequestHeaders.Add("Date", date);
                client.DefaultRequestHeaders.Add("x-log-signaturemethod", "hmac-sha1");
                client.DefaultRequestHeaders.Add("ContentMD5", contentMD5);
                content.Headers.ContentType = new MediaTypeHeaderValue("application/json");

                try
                {
