在 C# 中通过 DocuSign api 登录时出现“操作已超时”错误

自 2018 年 5 月 31 日起，我在登录 DocuSign API 时收到以下错误。

DocuSign.eSign.Client.ApiException：“调用登录时出错：操作已超时”。

自去年以来，我们一直在测试 DocuSign API，并且与我们的内部集成应用程序一起运行良好。昨天是我们第一次在登录时收到此错误消息，但问题仍然存在。如果我通过演示 DocuSign 网站登录https://appdemo.docusign.com，我可以登录了。 但如果我通过 DocuSign API 尝试相同的操作，则会出现超时错误。

Configuration.ApiClient.Configuration.ApiClient.RestClient.BaseUrl被设定为https://demo.docusign.net/restapi/

new System.Collections.Generic.Mscorlib_DictionaryDebugView<string, string>(Configuration.DefaultHeader).Items[0]被设定为{[X-DocuSign-Authentication, {"Username":[username], "Password":[password], "IntegratorKey":[IntegratorKey]}]}

我们根本没有更改用户名、密码或 IntegratorKey。

的价值response.StatusCode返回为 0。请在下面找到我的登录代码。

public ApiResponse< LoginInformation > LoginWithHttpInfo (AuthenticationApi.LoginOptions options = null)
    {            

        var path_ = "/v2/login_information";

        var pathParams = new Dictionary<String, String>();
        var queryParams = new Dictionary<String, String>();
        var headerParams = new Dictionary<String, String>(Configuration.DefaultHeader);
        var formParams = new Dictionary<String, String>();
        var fileParams = new Dictionary<String, FileParameter>();
        Object postBody = null;

        // to determine the Content-Type header
        String[] httpContentTypes = new String[] {

        };
        String httpContentType = Configuration.ApiClient.SelectHeaderContentType(httpContentTypes);

        // to determine the Accept header
        String[] httpHeaderAccepts = new String[] {
            "application/json"
        };
        String httpHeaderAccept = Configuration.ApiClient.SelectHeaderAccept(httpHeaderAccepts);
        if (httpHeaderAccept != null)
            headerParams.Add("Accept", httpHeaderAccept);

        // set "format" to json by default
        // e.g. /pet/{petId}.{format} becomes /pet/{petId}.json
        pathParams.Add("format", "json");


        if (options != null)
        {
            if (options.apiPassword != null) queryParams.Add("api_password", Configuration.ApiClient.ParameterToString(options.apiPassword)); // query parameter
            if (options.includeAccountIdGuid != null) queryParams.Add("include_account_id_guid", Configuration.ApiClient.ParameterToString(options.includeAccountIdGuid)); // query parameter
            if (options.loginSettings != null) queryParams.Add("login_settings", Configuration.ApiClient.ParameterToString(options.loginSettings)); // query parameter

        }


        // make the HTTP request
        IRestResponse response = (IRestResponse) Configuration.ApiClient.CallApi(path_, 
            Method.GET, queryParams, postBody, headerParams, formParams, fileParams,
            pathParams, httpContentType);

        int statusCode = (int) response.StatusCode;

        if (statusCode >= 400)
            throw new ApiException (statusCode, "Error calling Login: " + response.Content, response.Content);
        else if (statusCode == 0)
            throw new ApiException (statusCode, "Error calling Login: " + response.ErrorMessage, response.ErrorMessage);

        return new ApiResponse<LoginInformation>(statusCode,
            response.Headers.ToDictionary(x => x.Name, x => x.Value.ToString()),
            (LoginInformation) Configuration.ApiClient.Deserialize(response, typeof(LoginInformation)));

    }
