How to send special characters in HttpPost payload c#

Question

我正在使用

post

类从客户端调用我的 .net 核心 api，我的 api 托管在 Azure 上。 当有效负载传递给带有简单数据且没有任何特殊字符的 api comntroler 方法时，调用会成功执行，但是当使用“&`` 等特殊字符进行调用时，它会被 api 网关拒绝，状态代码为

httpclient

。我们无法更改 Azure api 网关政策，所以我需要如何更改我的帖子数据内容以在帖子方法中发送特殊字符。

private ByteArrayContent GetSerializeContent(dynamic content)
        {
            var serilizedContent = JsonConvert.SerializeObject(content);
            var buffer = System.Text.Encoding.UTF8.GetBytes(serilizedContent);
            var result = new ByteArrayContent(buffer);
            result.Headers.ContentType = new MediaTypeHeaderValue("application/json");

            return result;
        }
