我正在尝试查询两个表中的数据，即public class AzureBlobStream : ActionResult
{
private string filename, containerName;
public AzureBlobStream(string containerName, string filename)
{
this.containerName = containerName;
this.filename = filename;
this.contentType = contentType;
}
public override void ExecuteResult(ControllerContext context)
{
var response = context.HttpContext.Response;
var request = context.HttpContext.Request;
var connectionString = ConfigurationManager.ConnectionStrings["Storage"].ConnectionString;
var account = CloudStorageAccount.Parse(connectionString);
var client = account.CreateCloudBlobClient();
var container = client.GetContainerReference(containerName);
var blob = container.GetBlockBlobReference(filename);
blob.FetchAttributes();
var fileLength = blob.Properties.Length;
var fileExists = fileLength > 0;
var etag = blob.Properties.ETag;
var responseLength = fileLength;
var buffer = new byte[4096];
var startIndex = 0;
//if the "If-Match" exists and is different to etag (or is equal to any "*" with no resource) then return 412 precondition failed
if (request.Headers["If-Match"] == "*" && !fileExists ||
request.Headers["If-Match"] != null && request.Headers["If-Match"] != "*" && request.Headers["If-Match"] != etag)
{
response.StatusCode = (int)HttpStatusCode.PreconditionFailed;
return;
}
if (!fileExists)
{
response.StatusCode = (int)HttpStatusCode.NotFound;
return;
}
if (request.Headers["If-None-Match"] == etag)
{
response.StatusCode = (int)HttpStatusCode.NotModified;
return;
}
if (request.Headers["Range"] != null && (request.Headers["If-Range"] == null || request.Headers["IF-Range"] == etag))
{
var match = Regex.Match(request.Headers["Range"], @"bytes=(\d*)-(\d*)");
startIndex = Util.Parse<int>(match.Groups[1].Value);
responseLength = (Util.Parse<int?>(match.Groups[2].Value) + 1 ?? fileLength) - startIndex;
response.StatusCode = (int)HttpStatusCode.PartialContent;
response.Headers["Content-Range"] = "bytes " + startIndex + "-" + (startIndex + responseLength - 1) + "/" + fileLength;
}
response.Headers["Accept-Ranges"] = "bytes";
response.Headers["Content-Length"] = responseLength.ToString();
response.Cache.SetCacheability(HttpCacheability.Public); //required for etag output
response.Cache.SetETag(etag); //required for IE9 resumable downloads
response.ContentType = blob.Properties.ContentType;
blob.DownloadRangeToStream(response.OutputStream, startIndex, responseLength);
}
}
和Response.AddHeader("Content-Disposition", "attachment; filename=" + filename); // force download
return new AzureBlobStream(blobContainerName, filename);
，使用日期范围在"tbl_tmpdtr"字段进行比较，即in_out "tbl_employee"我有两个输入类型=我在我的视图中将“日期”传递给我的控制器tbl_tmpdtr datetime().以在我的模型中使用，请查看下面的代码。
{ $this->input->post('from_date');我的问题：变量$ a和$ b被视为列;
