如何反序列化或模仿响应类型

Question

我正在检索帐户：

    public async Task<JObject> GetAccount(string query)
    {
        var task = await Client.Instance.GetAsync(Client.Instance.BaseAddress + query);
        var jsonString = await task.Content.ReadAsStringAsync();
        var account = JsonConvert.DeserializeObject<JObject>(jsonString);
        return account;
    }

无论Client.Instance.GetAsync...是返回200还是400或任何其他响应类型，当响应被反序列化为帐户(JObject)时，响应始终为200。

我们如何从JObject获取响应类型？

您从内部查询的响应中获取响应类型。该行动基本上充当代理人。使用内部查询的响应来构造传递给调用客户端的响应。

public async Task<IHttpActionResult> GetAccount(string query) {
    //get the query response NOTE: assuming it is HttpResponseMessage
    var queryResponse = await Client.Instance.GetAsync(Client.Instance.BaseAddress + query);
    //get the status code for pass through
    var queryResponseStatus = queryResponse.StatusCode;
    //content to be passed on in the response
    var jsonString = await queryResponse.Content.ReadAsStringAsync();
    //create response message with status code
    var responseMessage = Request.CreateResponse(queryResponseStatus);
    //assign the content of the response
    responseMessage.Content = new StringContent(jsonString, Encoding.UTF8, "application/json");
    //return the result
    return ResponseMessage(responseMessage);
}
