Token Token_stream::get()

The function `get()` in the `Token_stream` class reads and returns the next token from the input stream. It first checks if there is a token already in the buffer (i.e., `full` is true), and if so, it returns that token and sets `full` to false. If the buffer is empty, it reads the input stream and extracts the next token using the `cin >>` operator. It then checks if the token is a valid token (e.g., a number or a symbol). If it is not a valid token, the function throws a `runtime_error` with an appropriate error message. If the token is valid, it sets `full` to true and returns the token.

"appid": "ttabc*****", "secret": "d428***********", "grant_type": "client_credential"用c#语言

根据提供的引用内容，这个问题似乎与生成SECRET_KEY密钥的方法没有关系。但是，我可以为您提供使用C#语言获取access_token的示例代码。请参考以下代码：

using System;
using System.Net;
using System.IO;
using System.Text;
using System.Web.Script.Serialization;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            string appid = "ttabc*****";
            string secret = "d428***********";
            string grant_type = "client_credential";
            string url = $"https://api.weixin.qq.com/cgi-bin/token?grant_type={grant_type}&appid={appid}&secret={secret}";

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Method = "GET";
            request.ContentType = "application/json";

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream myResponseStream = response.GetResponseStream();
            StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));            string retString = myStreamReader.ReadToEnd();

            JavaScriptSerializer serializer = new JavaScriptSerializer();
            dynamic json = serializer.Deserialize<dynamic>(retString);

            string access_token = json["access_token"];
            int expires_in = json["expires_in"];

            Console.WriteLine($"access_token: {access_token}");
            Console.WriteLine($"expires_in: {expires_in}");
        }
    }
}

分析python代码import requests,json headers = {'X-Auth-Token':'gAAAAABjfHU-k2du5UUc5yXk-V8mnFONCVSBJQIbU22vKvvxk7ibL6tsk6GlbCF1VLwWNpwJjMLIRRz_vzZ0v84B71Hk6NvWZnr8Lt1FTsjVLtVjaaZ4KXipMqgMjo3_25LeQgzHKmS87z6eDrTQfsmAwb0Ptl4dFAgHNbsEKsc3c0Od3v0DL2Y'} auth_url = 'http://controller:5000/v3/auth/tokens' #不能删，这部分有评分 url = 'http://controller:9292/v2.1/images' rsp = requests.get(url,headers=headers) for i in rsp.json()['images']: if 'cirros001' == i['name']: requests.delete('http://controller:9292/v2.1/images/{}'.format(i['id']),headers=headers) data = {'name':'cirros001','disk_format':'qcow2','container_format':'bare'} rsp = requests.post(url,data=json.dumps(data),headers=headers) image_id = rsp.json()['id'] headers['Content-Type'] = 'application/octet-stream' data = open('/root/cirros-0.3.4-x86_64-disk.img','rb') rsp_1 = requests.put('http://controller:9292/v2.1/images/{}'.format(image_id),headers=headers,data=data) print(rsp.json())

这段代码是使用Python的`requests`和`json`模块来进行HTTP请求的示例。它首先定义了一个包含认证信息的`headers`字典，然后使用`requests.get()`方法发送一个GET请求来获取图片列表。接着，它遍历返回的JSON数据，并根据图片的名称进行删除操作。接下来，它使用`requests.post()`方法发送一个POST请求来创建一个新的图片资源，并从返回结果中获取到新图片的ID。然后，它设置了`Content-Type`头部为`application/octet-stream`，并打开本地的一个图片文件，使用`requests.put()`方法发送一个PUT请求来上传图片内容。最后，它打印了最初的POST请求的返回结果。

需要注意的是，这段代码中的URL和认证信息是示例数据，你需要根据实际情况进行修改。
