Question

http://ssw.com/profile/?apikey = skdwkdkfkkdj

我尝试使用

public async Task<string> GetFromUriAsync(string requestUri, string token)
    {
        var client = new HttpClient();

        client.BaseAddress = new Uri(BaseUri);

        client.DefaultRequestHeaders.Authorization =
            new AuthenticationHeaderValue("apikey", "=" + token);
        HttpResponseMessage response = await client.GetAsync(requestUri);
        response.EnsureSuccessStatusCode();
        string responseBody = await response.Content.ReadAsStringAsync();

        return responseBody;
    }

然后返回null

我错过了什么或完全错了吗？

您尝试在HTTP请求的标头信息中传递API密钥。您需要做的就是传递整个URL而不需要任何其他标题信息。

IE：使用＆＃34; http://ssw.com/profile?apikey=abcdef＆＃34;作为requestUri并将令牌发送为null。另外，删除client.DefaultRequestHeaders.Authorization属性的设置。授权意味着用户/通过系统，而不是基于令牌的系统。

要测试此功能，请下载Fiddler 4（https://www.telerik.com/download/fiddler）。一旦你安装了小提琴手，就可以在＃34; Composer＆＃34;选项卡，您可以通过将URL直接放入URL框并单击＆＃34;执行＆＃34;来测试您需要的不同查询。然后，您将能够使用检查员查看响应并找出您需要从哪里开始。

以下是我用于HTTP GET和POST操作的类：

    public static string HTTPGET(string url)
    {
        try
        {
            HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url);
            request.Timeout = 100000;
            HttpWebResponse response = (HttpWebResponse) request.GetResponse();
            Stream responseStream = response.GetResponseStream();

            if (responseStream != null)
                using (StreamReader resStream = new StreamReader(responseStream))
                    return resStream.ReadToEnd();
            return null;
        }
        catch (Exception e)
        {
            Console.WriteLine(url);
            Console.WriteLine(e);
            return null;
        }
    }

    public static string HTTPPOST(string url, string postData)
    {
        try
        {
            HttpWebRequest webRequest = (HttpWebRequest) WebRequest.Create(url);
            webRequest.Method = "POST";
            webRequest.ContentType = "x-www-form-urlencoded";

            byte[] byteArray = Encoding.UTF8.GetBytes(postData);
            using (Stream requestStream = webRequest.GetRequestStream())
                requestStream.Write(byteArray, 0, byteArray.Length);
            using (Stream responseStream = webRequest.GetResponse().GetResponseStream())
                if (responseStream != null)
                    using (StreamReader responseReader = new StreamReader(responseStream))
                        return responseReader.ReadToEnd();
            return null;
        }
        catch (Exception e)
        {
            Console.WriteLine(url);
            Console.WriteLine(postData);
            Console.WriteLine(e);
            return null;
        }
    }

如何使用C＃中的给定api密钥获取http内容？
