Change the customBinding in the web.config to use larger defaults. I picked 2MB as it is a reasonable size. Of course setting it to 2GB (as your code suggests) will work but it does leave you more vulnerable to attacks. Pick a size that is larger than your largest request but isn't overly large.
更改 web.config 中的 customBinding 以使用更大的默认值。我选择了 2MB，因为它是一个合理的大小。当然，将其设置为 2GB（如您的代码所示）会起作用，但它确实会让您更容易受到攻击。选择比您最大的要求大但又不过大的尺寸。

You need to set basicHttpBinding -> MaxReceivedMessageSizein the client configuration.
您需要在客户端配置中设置basicHttpBinding -> MaxReceivedMessageSize。
