Question

我尝试使用C＃中的restsharp调用Postmarks电子邮件服务RestAPI并获取＆＃34; {\＆＃34; ErrorCode \＆＃34;：402，\＆＃34;消息\＆＃34;：\＆＃34;收到无效的JSON输入。\＆＃34;}＆＃34;每次我发送它的错误，即使我已经将数据格式设置为json，我甚至尝试过自定义json序列化。我不确定我是否正确设置参数甚至它是实现我尝试的最佳方式，所以任何帮助和建议都会受到欢迎。

public void SendRest(string emailAddress, string subject, string body, params string[] recipients)
    {
        var recipientString = "";
        foreach (var recipient in recipients)
        {
            recipientString = recipientString + recipient + ',';
        }

        var client = new RestClient();
        client.BaseUrl = new Uri("https://api.postmarkapp.com/email");

        var request = new RestRequest(Method.POST);
        request.RequestFormat = DataFormat.Json;
        request.AddHeader("Content-Type", "application/json");
        request.AddHeader("Accept", "application/json");
        request.AddHeader("X-Postmark-Server-Token", "Valid-Token");

        request.AddParameter("From", "test@testington.co.uk");
        request.AddParameter("To", "robin.windon@hotmail.co.uk");
        request.AddParameter("Subject", "hi");
        request.AddParameter("TextBody", "this is a test");
        request.AddParameter("TrackOpens", true);
        request.AddParameter("TrackLinks", "None");


        IRestResponse response = client.Execute(request);
    }

您将参数作为（序列化）POST参数（在正文中）或GET参数发送，我不确定restsharp如何处理这个。

但是你没有根据需要在POST正文中发送任何JSON。

我想这应该是这样的：

var params = JSON.Stringify(
    {
        "From": "robin.windon...",
        "To": "",
        "Subject": "",
        "TextBody": "",
        "TrackOpens": "",
        "TrackLinks": ""
    }
);
request.AddParameter("application/json", params, ParameterType.RequestBody);

＆＃34; {\＆＃34; ErrorCode \＆＃34;：402，\＆＃34;消息\＆＃34;：\＆＃34;收到无效的JSON输入。\＆＃34;}＆＃34 ;尝试调用restsharp来调用Postmark时
