Base64字符串太长
我已经使web服务从android应用程序接收base64string和图像名称。 但问题是，当我将base64string的值传入webservice时，出现错误

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.

这是我的web服务：
[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;
}
}
我不知道我是否需要在web.config中做一些事情，或者最小化base64string的长度。 任何想法。谢谢
是的，您需要在web.config中进行更改。 当你看到提供的错误它说
这是一项安全功能。 除非完全了解变更的范围，否则请勿更改此功能。 您可以将IIS服务器配置为拒绝查询字符串大于指定值的请求。 如果请求的查询字符串大于配置值，则返回此错误。 如果需要增加查询字符串的允许长度，请修改configuration/system.webServer/security/requestFiltering/requestLimits@maxQueryString设置。
将以下内容添加到您的web.config中
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxQueryString="32768"/>
</requestFiltering>
</security>
</system.webServer>
和
<httpRuntime maxQueryStringLength="32768" maxUrlLength="65536"/>
如requestFiltering [IIS设置架构]，请求筛选和httpRuntime元素（ASP.NET设置架构）的requestLimits元素中所述。
