RestSharp -如何处理非200响应?RestClient在执行时抛出异常

本文关键字：RestClient 响应 执行 抛出异常 何处理 处理 RestSharp | 更新日期: 2023-09-27 18:15:05

我在Windows Phone 8.1应用程序中使用RestSharp。当服务器返回代码不同于200的响应时，RestClient抛出异常。Wiki说我应该得到正确状态码的响应。我想获得响应的内容，因为服务器返回错误消息。

private async Task<T> ExecuteAsync<T>(IRestRequest request)
    {
        if (!_networkAvailableService.IsNetworkAvailable)
        {
            throw new NoInternetException();
        }
        request.AddHeader("Accept", "application/json");
        IRestResponse<T> response;
        try
        {
            response = await _client.Execute<T>(request); //here I get exception
        }
        catch (Exception ex)
        {
            throw new ApiException();
        }
        HandleApiException(response);
        return response.Data;
    }
    private void HandleApiException(IRestResponse response)
    {
        if (response.StatusCode == HttpStatusCode.OK)
        {
            return;
        }
//never reach here :( 
        ApiException apiException;
        try
        {
            var apiError = _deserializer.Deserialize<ApiErrorResponse>(response);
            apiException = new ApiException(apiError);
        }
        catch (Exception)
        {
            throw new ApiException();
        }
        throw apiException;
    }
服务器响应示例: 
HTTP/1.1 400 Bad Request

Pragma: no-cache
Content-Length: 86
Content-Type: application/json;charset=UTF-8
Expires: -1

如果你在Windows Phone 8.1下工作，你正在使用RestSharp Portable (https://github.com/FubarDevelopment/restsharp.portable)(可能)。使用这个:

var client = new RestClient();
client.IgnoreResponseStatusCode = true;
有了这个，你就不会得到例如404的异常。希望对大家有所帮助。
