Question

所以我试图使用this api从服务器获取JSON响应问题是它返回网站homepage的html代码。如果你看一下api页面，它会说它应该返回一些json。我认为我的代码存在问题。

有什么建议吗？

图片使用：

我的代码：

        static void Main(string[] args)
    {
        Image img = Image.FromFile("image.jpg");
        String base64 = ImageToBase64(img, System.Drawing.Imaging.ImageFormat.Jpeg);

        var request = (HttpWebRequest)WebRequest.Create("http://www.whatanime.ga/api/search?token=<token>");

        var postData = base64;
        var data = Encoding.UTF8.GetBytes(postData);

        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";

        using (var stream = request.GetRequestStream())
        {
            stream.Write(data, 0, data.Length);
        }

        var response = (HttpWebResponse)request.GetResponse();

        var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

        Console.WriteLine("data:" + responseString);
        Console.ReadLine();
    }

    public static string ImageToBase64(Image image, System.Drawing.Imaging.ImageFormat format)
    {
        using (MemoryStream ms = new MemoryStream())
        {
            image.Save(ms, format);
            byte[] imageBytes = ms.ToArray();

            string base64String = Convert.ToBase64String(imageBytes);
            return base64String;
        }
    }

好吧，在与其他选项混淆之后，我找到了一个有效的（对我而言）解决方案我发布这个是为了帮助未来的人们解决同样的问题。

        String base64 = ImageToBase64(img, System.Drawing.Imaging.ImageFormat.Jpeg);

        using (var client = new WebClient())
        {
            var values = new NameValueCollection();
            values["image"] = base64;
            var response = client.UploadValues("https://whatanime.ga/api/search?token=<token>", values);
            var responseString = Encoding.Default.GetString(response);
            Console.WriteLine("data: " + responseString);
            Console.ReadLine();
        }

            string base64String = Convert.ToBase64String(imageBytes);
            return base64String;
        }
    }
}

正如我在文档中读到的那样

POST /api/search?token={your_api_token} HTTP/1.1
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
Host: whatanime.ga

image={Base64 Encoded Image}

您必须提供密钥对值才能提供图像

类似这样的事情

using (WebClient client = new WebClient())
{
    response = client.UploadValues("http://www.whatanime.ga/api/search?token=<token>", 
        new NameValueCollection() {{ "image", base64 }
    });
}

结束读取响应状态

Returns HTTP 403 if API token is invalid.

Returns HTTP 401 if API token is missing.   

Note that there is a hard limit of 1MB post size. You should ensure your Base64 encoded image is < 1MB. Otherwise the server responds with HTTP 413 (Request Entity Too Large).

HTTP Post返回整个网站html而不是JSON响应
