c# - 添加新的 Jtoken 到 Json Jtoken

Question

我有以下 Json

{
  "error": {
    "errors": [
      {
        "domain": "global",
        "reason": "required",
        "message": "Login Required",
        "locationType": "header",
        "location": "Authorization"
      }
    ],
    "code": 401,
    "message": "Login Required"
  }
}

我想做的是在 "message": "Login Required" 下添加一个新的 JToken 类似 "RetryMessage": "Failed after 10重试”

我找到了这个 How do you add a JToken to an JObject?我认为这不太有效，因为错误是一个标记而不是一个对象，但我不确定。

我尝试过的:

var JsonObj = JObject.Parse(response);
var RetryMessageJson = JToken.Parse(@"{ ""RetryMessage"" : ""UnKnown""}");
JsonObj["error"]["message"].AddAfterSelf(RetryMessageJson);

我已经尝试了上面代码的几个版本，它们都返回了以下错误消息:

Newtonsoft.Json.Linq.JProperty cannot have multiple values.

除非顺序确实很重要，否则我怀疑您只是想让它成为错误的另一个属性:

// Variable names edited to follow normal C# conventions
var jsonResponse = JObject.Parse(response);
jsonResponse["error"]["retryMessage"] = "Unknown";

使用您的示例 JSON，结果为:

{
  "error": {
    "errors": [
      {
        "domain": "global",
        "reason": "required",
        "message": "Login Required",
        "locationType": "header",
        "location": "Authorization"
      }
    ],
    "code": 401,
    "message": "Login Required",
    "retryMessage": "Unknown"
  }
}
