问题描述
你好，
在网络应用程序中，我必须使用api将文件上传到另一个站点/服务器。
请帮助缩短此查询..
$代码下面的b $ b给出了操作有超时错误。
hello,
In web application i have to upload file to another site/server using api.
Please help to shortout this query..
below code gives "Operation has timeout error."
if (FileUpload1.HasFile)
{
string path = Path.GetFullPath(FileUpload1.PostedFile.FileName);
string fileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
string fileExtension = Path.GetExtension(FileUpload1.PostedFile.FileName);

Kinjal，
建议您使用数据驱动的请求系统，而不是直接上传
插入请求数据&运行循环
Kinjal,
You are recommended to use data driven request system, not direct by upload
insert request to data & run loop
httpWebRequest2.MaximumResponseHeadersLength = 100000;
httpWebRequest2.ReadWriteTimeout = 200000;
你得到了你自己的价值
请参考下面给出的bulksms的api样本
祝你好运
you get set your own value
plz refer below given bulksms''s api sample
Good Luck
