解析值时遇到意外字符：<。路径 ''，第 0 行，位置 0。同时通过 mashape 调用炼金术 api

Question

public class keywords
{
   [JsonProperty(PropertyName = "text")]
   public string text { get; set; }
   [JsonProperty(PropertyName = "relevance")]
   public string relevance { get; set; }
}
public class JsonData
{
   [JsonProperty(PropertyName = "status")]
   public string status { get; set; }
   [JsonProperty(PropertyName = "usage")]
   public string usage { get; set; }
   [JsonProperty(PropertyName = "url")]

   public string url { get; set; }
   [JsonProperty(PropertyName = "language")]
   public string language { get; set; }
   [JsonProperty ("keywords")]
   public keywords keyword { get; set; }     
}

以上是我用来反序列化通过调用炼金术 API.

收到的 json 响应的类

string url =     "https://alchemy.p.mashape.com/Text/TextGetRankedKeywords?outputMode=json&text=" + text;
var response = (Unirest.get("https://alchemy.p.mashape.com/Text/TextGetRankedKeywords?outputMode=json&text=" + text)
   .header("X-Mashape-Key", "AlZVYH30C9mshLPNM7KiE48aFfTHp1h3A31jsnmVPccxBzW5uB")
   .header("Accept", "application/json")
   .asJson<JsonData>()
   .Body);
var status = response.keyword.text;
var score = response.keyword.relevance;

我收到这个错误：

An exception of type 'Newtonsoft.Json.JsonReaderException' occurred in Newtonsoft.Json.dll but was not handled in user code

Additional information: Unexpected character encountered while parsing value: <. Path '', line 0, position 0.

Answer 1

我在 url 中犯了一个错误。 url 是“https://alchemy.p.mashape.com/text/TextGetRankedKeywords?outputMode=json&text=” 此外，我需要在 JsonData class

中创建关键字对象的数组实例

解析值时遇到意外字符：<。路径 ''，第 0 行，位置 0。同时通过 mashape 调用炼金术 api
