Token Token_stream::get()
时间: 2024-05-27 12:10:56 浏览: 16
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:
```csharp
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}");
}
}
}
```
C# HttpWebRequest Get 并且 OAuth 2.0 access Token 配置
在 C# 中使用 `HttpWebRequest` 发送 GET 请求,并且配置 OAuth 2.0 的 `access token`,可以按照以下步骤进行:
1. 构建请求的 URL,将参数和 `access token` 拼接在 URL 后面,例如:
```csharp
string url = "https://example.com/api/endpoint?param1=value1&access_token=your_access_token";
```
2. 创建 `HttpWebRequest` 对象,设置请求方法为 GET,设置请求头的 `User-Agent` 字段,例如:
```csharp
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "GET";
request.UserAgent = "Mozilla/5.0";
```
3. 发送请求,获取响应结果,例如:
```csharp
WebResponse response = request.GetResponse();
Stream stream = response.GetResponseStream();
StreamReader reader = new StreamReader(stream);
string result = reader.ReadToEnd();
```
完整的示例代码如下:
```csharp
string url = "https://example.com/api/endpoint?param1=value1&access_token=your_access_token";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "GET";
request.UserAgent = "Mozilla/5.0";
WebResponse response = request.GetResponse();
Stream stream = response.GetResponseStream();
StreamReader reader = new StreamReader(stream);
string result = reader.ReadToEnd();
```
需要注意的是,`access token` 的获取方式和拼接在 URL 后面的参数需要根据具体情况进行实现。同时,请求头中的 `User-Agent` 字段也需要根据实际情况进行设置。
