.NET Core 2.2 无法处理正文中的加密字符串，即使 Mediatype 显示 application/json

Question

我有一个第三方正在向我的 API 发布请求...他们发布加密文本作为正文，但也包括应用程序/JSON 作为内容类型。有什么方法可以让 .Net Core 2.2 来处理这个问题......我试过...

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

和

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

但两者都不起作用。

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

Answer 1

[HttpPost("/callback/thirdparty")]
[AllowAnonymous]
public IActionResult Thirdparty()
{
try
{
using (StreamReader reader = new StreamReader(Request.Body))
{
var body = reader.ReadToEnd();

现在我身上有一根绳子！
