Question

我想在我的应用中使用短信网关。这就是我与操作员联系的原因，操作员给我一个api格式。

网址：https://ideabiz.lk/apicall/smsmessaging/v2/outbound/3313/requests

请求标题

Content-Type: application/json 
Authorization: Bearer [access token] 
Accept: application/json

体

{
    "outboundSMSMessageRequest": {
        "address": [
            "tel:+94771234567"
        ],
        "senderAddress": "tel:12345678",
        "outboundSMSTextMessage": {
            "message": "Test Message"
        },
        "clientCorrelator": "123456",
        "receiptRequest": {
            "notifyURL": "http://128.199.174.220:1080/sms/report",
            "callbackData": "some-data-useful-to-the-requester"
        },
        "senderName": "ACME Inc."
    }
}

现在，我编写代码：

RestClient client = new RestClient(@"https://ideabiz.lk/");
RestRequest req = new RestRequest(@"apicall/smsmessaging/v2/outbound/3313/requests", Method.POST);

req.AddHeader("Content-Type", @"application/json");
req.AddHeader("Authorization", @"Bearer " + accessToken.ToString());
req.AddHeader("Accept", @"application/json");

string jSon_Data = @"{'outboundSMSMessageRequest': {'address': ['tel:+94768769027'],'senderAddress': 'tel:3313','outboundSMSTextMessage': {'message': 'Test Message : " + System.DateTime.Now.ToString() + "'},'clientCorrelator': '123456','receiptRequest': {'notifyURL': 'http://128.199.174.220:1080/sms/report','callbackData': 'some-data-useful-to-the-requester'},'senderName': ''}}";


JObject json = JObject.Parse(jSon_Data);
req.AddBody(json);

IRestResponse response = client.Execute(req);
string x = response.Content.ToString();
Console.WriteLine(x.ToString());

当我执行此程序时，在

行中

req.AddBody（JSON）;

我的系统崩溃，并提供错误消息：

System.Windows.Forms.dll中出现未处理的“System.StackOverflowException”类型异常

如何使用C＃.NET发布复杂的JSON？

这里有两个问题：

您需要在致电RequestFormat = DataFormat.Json之前设置AddBody：
```
    req.RequestFormat = DataFormat.Json;
    req.AddBody(json);
```
如果不设置参数，RestSharp会尝试将JObject 序列化为XML 并在某处进入无限递归 - 最有可能尝试序列化JToken.Parent。

更新版本的RestSharp no longer use Json.NET作为其JSON序列化程序：

There is one breaking change: the default Json*Serializer* is no longer 
compatible with Json.NET. To use Json.NET for serialization, copy the code 
from https://github.com/restsharp/RestSharp/blob/86b31f9adf049d7fb821de8279154f41a17b36f7/RestSharp/Serializers/JsonSerializer.cs 
and register it with your client:

var client = new RestClient();
client.JsonSerializer = new YourCustomSerializer();

RestSharp的新内置JSON序列化程序无法理解JObject所以如果您使用的是其中一个更新的版本，则需要按照上述说明创建：

public class JsonDotNetSerializer : ISerializer
{
    private readonly Newtonsoft.Json.JsonSerializer _serializer;

    /// <summary>
    /// Default serializer
    /// </summary>
    public JsonDotNetSerializer() {
        ContentType = "application/json";
        _serializer = new Newtonsoft.Json.JsonSerializer {
            MissingMemberHandling = MissingMemberHandling.Ignore,
            NullValueHandling = NullValueHandling.Include,
            DefaultValueHandling = DefaultValueHandling.Include
        };
    }

    /// <summary>
    /// Default serializer with overload for allowing custom Json.NET settings
    /// </summary>
    public JsonDotNetSerializer(Newtonsoft.Json.JsonSerializer serializer){
        ContentType = "application/json";
        _serializer = serializer;
    }

    /// <summary>
    /// Serialize the object as JSON
    /// </summary>
    /// <param name="obj">Object to serialize</param>
    /// <returns>JSON as String</returns>
    public string Serialize(object obj) {
        using (var stringWriter = new StringWriter()) {
            using (var jsonTextWriter = new JsonTextWriter(stringWriter)) {
                jsonTextWriter.Formatting = Formatting.Indented;
                jsonTextWriter.QuoteChar = '"';

                _serializer.Serialize(jsonTextWriter, obj);

                var result = stringWriter.ToString();
                return result;
            }
        }
    }

    /// <summary>
    /// Unused for JSON Serialization
    /// </summary>
    public string DateFormat { get; set; }
    /// <summary>
    /// Unused for JSON Serialization
    /// </summary>
    public string RootElement { get; set; }
    /// <summary>
    /// Unused for JSON Serialization
    /// </summary>
    public string Namespace { get; set; }
    /// <summary>
    /// Content type for serialized content
    /// </summary>
    public string ContentType { get; set; }
}

然后做：

    RestRequest req = new RestRequest(@"apicall/smsmessaging/v2/outbound/3313/requests", Method.POST);
    req.JsonSerializer = new JsonDotNetSerializer();

在身体发布中使用C＃.NET复杂json数据的REST api
