Leaf.XNet C#将正文作为Json发送不起作用

Question

HttpRequest httpRequest = new HttpRequest();
RequestParams reqParams = new RequestParams { };
httpRequest.IgnoreProtocolErrors = true;

reqParams["data"] = "{\"path\": \"/Prime_Numbers.txt\"}";
httpRequest.AddHeader("Authorization", " Bearer MYKEY");
httpRequest.AddHeader("Content-Type", "application/json");

Console.WriteLine(httpRequest.Post("https://api.dropboxapi.com/2/sharing/create_shared_link_with_settings", reqParams).ToString());

我收到以下错误：调用 API 函数“sharing/create_shared_link_with_settings”时出错：请求正文：无法将输入解码为 JSON。我正在使用 Dropbox api。

我看到了以下内容：https://github.com/csharp-leaf/Leaf.xNet/issues/66（有人遇到过类似问题，但此修复无效）

当您使用RequestParams 时，表示Context-Type: application/x-www-form-urlencoded。
您不能通过.AddHeader() 设置Content-Type，请使用.Post(url, json, contentType) 方法的参数，如下所示：

HttpRequest httpRequest = new HttpRequest();
httpRequest.AddHeader("Authorization", " Bearer MYKEY");

string url = "https://api.dropboxapi.com/2/sharing/create_shared_link_with_settings";
string jsonData = "{\"path\": \"/Prime_Numbers.txt\"}";
string response = httpRequest.Post(url, jsonData, "application/json").ToString();

Console.WriteLine(response);
