首先Accept与Accept-Charset是分开的，两个属性。
其次application/json; charset=utf-8是Content-Type的写法。
C# 代码：
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json", 1));
client.DefaultRequestHeaders.AcceptCharset.Add(new StringWithQualityHeaderValue("utf-8", 1));
using var body = new StringContent("{A:1, B:2}", Encoding.UTF8, "application/json");
var resp = await client.PostAsync("/manager/api/login", body);
请求头：
......
Accept: application/json; q=1.0
Accept-Charset: utf-8; q=1.0
Content-Type: application/json; charset=utf-8

谢了，已经解决了。确实是分开了,找了好久。_httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json") { CharSet = "utf-8" });
var stringContent = new StringContent(json, Encoding.UTF8);
stringContent.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream") { CharSet = "utf-8" };
对接方的接口要求如图
即：Http Header 必须是这种格式，还要参与签名计算，你那种写法调不通。
Accept:application/json; charset=utf-8
Content-Type:application/octet-stream; charset=utf-8
