一、基本情况
目前网络服务多以Http方式直接传播数据信息。在本次调用中，首先是
开通权限
而后是鉴权
public static class AccessToken
{
// 调用getAccessToken()获取的 access_token建议根据expires_in 时间 设置缓存
// 返回token示例
public static String TOKEN = "24.adda70c11b9786206253ddb70affdc46.2592000.1493524354.282335-1234567";
// 百度云中开通对应服务应用的 API Key 建议开通应用的时候多选服务
private static String clientId = "VGzQ7jWz57mBGcDTYACgbAaD";
// 百度云中开通对应服务应用的 Secret Key
private static String clientSecret = "RZOcID2IRUCccUGzXdihZKjaoCMTZIth";
public static String getAccessToken()
{
String authHost = "https://aip.baidubce.com/oauth/2.0/token";
HttpClient client = new HttpClient();
List<KeyValuePair<String, String>> paraList = new List<KeyValuePair<string, string>>();
paraList.Add(new KeyValuePair<string, string>("grant_type", "client_credentials"));
paraList.Add(new KeyValuePair<string, string>("client_id", clientId));
paraList.Add(new KeyValuePair<string, string>("client_secret", clientSecret));
HttpResponseMessage response = client.PostAsync(authHost, new FormUrlEncodedContent(paraList)).Result;
String result = response.Content.ReadAsStringAsync().Result;
Console.WriteLine(result);
return result;
}
最后是调用
public class SkySeg
{
// 天空分割
public static string skySeg()
{
string token = "24.f3ad594ec508e2830506909191535524.2592000.1602456936.282335-18132305";
string host = "https://aip.baidubce.com/rest/2.0/image-process/v1/sky_seg?access_token=" + token;
Encoding encoding = Encoding.Default;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(host);
request.Method = "post";
request.KeepAlive = true;
// 图片的base64编码
string base64 = getFileBase64("E:/sky.jpg");
String str = "image=" + HttpUtility.UrlEncode(base64);
byte[] buffer = encoding.GetBytes(str);
request.ContentLength = buffer.Length;
request.GetRequestStream().Write(buffer, 0, buffer.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.Default);
string result = reader.ReadToEnd();
Console.WriteLine("天空分割:");
Console.WriteLine(result);
return result;
}
public static String getFileBase64(String fileName)
{
FileStream filestream = new FileStream(fileName, FileMode.Open);
byte[] arr = new byte[filestream.Length];
filestream.Read(arr, 0, (int)filestream.Length);
string baser64 = Convert.ToBase64String(arr);
filestream.Close();
return baser64;
}
获得结果（上部分是鉴权结果，下部分是编码结果）

二、延伸研究
对于这样一个平台，最后如果部署为网络 服务，肯定还是走Python js等语言，所以Csharp只是简单测试一下。我想思考的问题是它的应用场景在哪里？我是否需要去做准备？然后应该去做什么准备？
使用DL去做图像增强，即使是Baidu也意识到是一个领域，但是他们很可能同样也应用场景不明，其局限应该还是“真”和“假”的区分。因为其根本，这里的增强并不是一种主观意识的正确（比如夜视、静脉穿刺、去雾等），它的容错率是很低的，如果做的不“真”，最终只能是停留在娱乐领域。但是从另一个方面来说，这个方面能力的积累却不能等到场景展现出来以后再做，至少现在就 应该有所积累。这个我是放在专门的项目中来说明的。
三、BAIDU_AI开放平台
可以看出倾向于CV，这个分类可以说是有参考价值的。
四、备注
获取Access Token
请求URL数据格式
向授权服务地址https://aip.baidubce.com/oauth/2.0/token发送请求（推荐使用POST），并在URL中带上以下参数：
- grant_type： 必须参数，固定为
client_credentials
- ；
- client_id： 必须参数，应用的
API Key
- ；
- client_secret： 必须参数，应用的
Secret Key
- ；
服务器返回的JSON文本参数如下：
- access_token： 要获取的Access Token；
- expires_in： Access Token的有效期(秒为单位，一般为1个月)；
- 其他参数忽略，暂时不用;
例如：
{
"refresh_token": "25.b55fe1d287227ca97aab219bb249b8ab.315360000.1798284651.282335-8574074",

"session_secret": "dfac94a3489fe9fca7c3221cbf7525ff"
}
