And here is my webservice :
[HttpPost]
[ActionName("GetImage")]
public string GetImage(string base64String, string imgName)
{
try
{
byte[] imageBytes = Convert.FromBase64String(base64String);
MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length);
ms.Write(imageBytes, 0, imageBytes.Length);
System.Drawing.Image image = System.Drawing.Image.FromStream(ms, true);
File.WriteAllBytes(Path.Combine
(@"F:FileManager"
, imgName
)
, imageBytes
);
return "Success";
}
catch (Exception ex)
{
return ex.Message;
}
}
I don't know if i need to do some thing in my web.config or minimize the length of base64string . Any Ideas .Thanks
Yes you need to do changes in the web.config. When you look at the provided error it says
This is a security feature. Do not change this feature unless the scope of the change is fully understood. You can configure the IIS server to reject requests whose query string is greater than a specified value. If the request's query string is greater than the configured value, this error is returned. If the allowed length of the query string needs to be increased, modify the configuration/system.webServer/security/requestFiltering/requestLimits@maxQueryString setting.
Add the following to your web.config
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxQueryString="32768"/>
</requestFiltering>
</security>
</system.webServer>
and
<httpRuntime maxQueryStringLength="32768" maxUrlLength="65536"/>
as described in the following references requestLimits Element for requestFiltering [IIS Settings Schema], Request Filtering and httpRuntime Element (ASP.NET Settings Schema).
