。net core 2.2无法处理正文中的加密字符串，即使mediatype表示application / json

Question

我有一个第三方向我的API发布请求...他们将加密文本作为正文发布，但还包括application / json作为内容类型。有什么方法可以让.Net Core 2.2处理此问题？我尝试过...

    [HttpPost("/callback/thirdparty")]
    [AllowAnonymous]
    public IActionResult Thirdparty([FromBody]dynamic body)
    {

和

    [HttpPost("/callback/thirdparty")]
    [AllowAnonymous]
    public IActionResult Thirdparty([FromBody]string body)
    {

但都没有用。

    Request Headers
    Content-Type: "application/json"
    Accept: "*/*"
    Cache-Control: "no-cache"
    Accept-Encoding: "gzip, deflate"
    Content-Length: 155
    Connection: "keep-alive"
    Request Body
