将数据填充到调用 API 端点的 class 中的方法不起作用

Question

I am trying to call a web api to get some JSON data and parse it into my c# class. 我已经把这部分记下来了，但是我无法使用返回的数据，特别是一个字段并调用第二个 web api 将此字段作为参数并获取返回的数据以完成我的 Z20F35E630DAF44DBFA4C3F68F53。 问题是我在尝试调用 GetZendeskOrgID 方法时遇到错误，并且错误指出它无法将 void 转换为 int。

解决这个问题的最佳方法是什么？ 提前致谢，

下面的代码：我已经用随机数据清理了敏感字段，所以不用担心。

public static async Task PersonQuery()
        {
            using (var client = new HttpClient())
            {
                // Format headers
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                // Request token, and append to headers
                await AddiMISTokenToHeaders(client);
                // Query HTTP Service                
                var response = await client.GetAsync(imisBaseURL + "api/IQA?queryName=$/RAEted");
                if (response.IsSuccessStatusCode)
                {
                    JObject result = JObject.Parse(await response.Content.ReadAsStringAsync());

Answer 1

在您的GetZendeskOrgID中， CompanyID参数可能为空。 如果您要求它有一个值，并且如果您要求该值是正 integer，您应该在该方法中进行错误检查。 就像是：

if(string.IsNullOrEmpty(CompanyID)){
    throw new NullReferenceException("CompanyId cannot be Null", CompanyID);
}
var outNum = -1;
var companyIdInt = Int.TryParse(CompanyId, out outNum)? OutNum : -1
if(companyIdInt<0){
    throw new Exception("CompanyId must be a number greater than -1");
}

或类似的东西...

Answer 2

As error says it is not able to convert void to int because organization_id is expecting integer back form function GetZendeskOrgID() but you are not returning anything from this function make it return int like this I am assuming that your response object has integer property so you将不得不像这样退回它

 public static async Task<int> GetZendeskOrgID(string CompanyID )

    {
        using (HttpClient client = new HttpClient())
        {
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(
                "Basic", "YMUZlOFhS");
            var response = await client.GetAsync("https://zendesk.com/api/v2/organizations/search.json?external_id=" + CompanyID);

             return response.oganization_id;
        }
    }
