鉴权

  • 客户端通过OAuth 2.0 Client Credentials方式进行鉴权
  • 请提前获取您的 API Key 和 API Secret
  • 鉴权URL：https://login.chinacloudapi.cn/387c56a8-cf86-45de-b9f5-b4de88cac054/oauth2/v2.0/token，以下统称为 AUTH_URL

获取Access Token

请求:

 - 请求URL:  AUTH_URL
 - http方法: POST
 - header :  "Content-Type"： "application/x-www-form-urlencoded" 
 - body:
   - "grant_type"："client_credentials" 
   - "client_id"：您的API Key
   - "client_secret"： 您的API Secret
   - "Type"："oauth2" 
   - "scope"： d6b7c858-55fa-4d04-85a6-131af690abd4/.default

响应：

{ 
    "token_type": "Bearer",  /*token 类型*/
    "expires_in": 3599, /*有效期/秒*/
    "ext_expires_in": 3599, 
    "access_token": ".........." /*授权码*/
}

如果Token过期，请重新使用该接口获取token

此步骤中获取的 access_token 作为访问API的凭证，在有效期内都可用此access_token，推荐客户端在有效期内缓存该 access_token

示例代码

curl -X "POST" "https://login.chinacloudapi.cn/387c56a8-cf86-45de-b9f5-b4de88cac054/oauth2/v2.0/token" \
     -H 'Content-Type: application/x-www-form-urlencoded' \
     --data-urlencode "grant_type=client_credentials" \
     --data-urlencode "client_id=替换API Key" \
     --data-urlencode "client_secret=替换API Secret" \
     --data-urlencode "Type=oauth2" \
     --data-urlencode "scope=d6b7c858-55fa-4d04-85a6-131af690abd4/.default"

    private const string AppClientId = "您的API Key";
    private const string AppClientSecret = "您的API Secret";
    private const string BaseUri = https://login.chinacloudapi.cn/387c56a8-cf86-45de-b9f5-b4de88cac054/oauth2/v2.0/token;

    static void Main(string[] args)
    {
        var tokenString = GetDevCenterApiToken();
        Console.WriteLine("BearerToken:" + tokenString);
    }

    static string GetDevCenterApiToken()
    {
        var tokenString = string.Empty;
        var httpclientHandler = new HttpClientHandler()
        {
            ServerCertificateCustomValidationCallback = (message, cert, chain, error) => true,
        };

        var fromContent = new FormUrlEncodedContent(new[]
        {
            new KeyValuePair<string,string>("client_id", AppClientId),
            new KeyValuePair<string,string>("client_secret", AppClientSecret),
            new KeyValuePair<string, string>("scope", "d6b7c858-55fa-4d04-85a6-131af690abd4/.default"),
            new KeyValuePair<string,string>("grant_type", "client_credentials"),
        });

        using (var httpClient = new HttpClient(httpclientHandler))
        {
            httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));
            var result = httpClient.PostAsync(BaseUri, fromContent).Result;
            tokenString = result.Content.ReadAsStringAsync().Result;
            Console.WriteLine(result.Content.ReadAsStringAsync().Result);
            httpClient.Dispose();
        }
        return tokenString;
    }

import requests


def send_request():
    # 获取token
    # POST https://login.chinacloudapi.cn/41ebb163-adc1-4068-9087-eb79c718b633/oauth2/v2.0/token

    try:
        response = requests.post(
            url="https://login.chinacloudapi.cn/387c56a8-cf86-45de-b9f5-b4de88cac054/oauth2/v2.0/token",
            headers={
                "Content-Type": "application/x-www-form-urlencoded",
            },
            data={
                "grant_type": "client_credentials",
                "client_id": "替换API Key",
                "client_secret": "API Secret",
                "Type": "oauth2",
                "scope": "d6b7c858-55fa-4d04-85a6-131af690abd4/.default",
            },
        )
        print('Response HTTP Status Code: {status_code}'.format(
            status_code=response.status_code))
        print('Response HTTP Response Body: {content}'.format(
            content=response.content))
    except requests.exceptions.RequestException:
        print('HTTP Request failed')

通过以上操作，您将获取您的Access Token，后续请求接口时，需要将其放到Headers中，格式为：Authorization: Bearer {access token}
