我正在使用mashape api:https://market.mashape.com/montanaflynn/dictionary
这是我的代码:
HttpResponse<RootObject> response = Unirest.get("https://montanaflynn-dictionary.p.mashape.com/define?word=irony")
.header("X-Mashape-Key", "my mashape key")
.header("Accept", "application/json")
.asJson<RootObject>();
生成了RootObject类
这是我的RootObject类代码:
class Definition
{
public string text { get; set; }
public string attribution { get; set; }
}
class RootObject
{
public List<Definition> definitions { get; set; }
}
当我运行上面的代码时,我收到以下错误:
未处理的类型&#39; System.InvalidCastException&#39;发生在unirest-net.dll中 附加信息:无法转换类型为#System ;IO.MemoryStream&#39;的对象输入&#39; RootObject&#39;。
问题:如何解决错误?
答案 0 :(得分:0)
试试这个。它必须放在异步函数中:
static async Task<RootObject> GetRootInfo()
{
HttpResponse<RootObject> response = await Unirest.get("https://montanaflynn-dictionary.p.mashape.com/define?word=irony")
.header("X-Mashape-Key", "my mashape key")
.header("Accept", "application/json")
.asJsonAsync<RootObject>();
return response.Body;
}
