RestSharp-如何处理非200响应?RestClient在Execute上引发异常 [英] RestSharp - How to handle non-200 responses? RestClient throws exception on Execute

问题描述

我在Windows Phone 8.1应用程序中使用RestSharp.服务器返回的响应代码不同于200时，RestClient会引发异常. Wiki 说，我应该获得正确的状态码响应.我想获取响应的内容，因为服务器返回了错误消息.

I'm using RestSharp in Windows Phone 8.1 application. RestClient throws exception when server returns response with code different than 200. Wiki says that I should get response with correct status code. I want to get content of response because server returns error messages.

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

{"error":"invalid_token","error_description":"The user name or password is incorrect"}

推荐答案

如果您在Windows Phone 8.1下工作，则使用的是RestSharp Portable(

If you are working under Windows Phone 8.1, you're using RestSharp Portable (https://github.com/FubarDevelopment/restsharp.portable) (probably). Use this:

var client = new RestClient();
client.IgnoreResponseStatusCode = true;

例如，您不会在404中遇到异常.希望对您有所帮助:)

With this, you don't get exception with 404 for example. I hope it will be helpful :)
