Openshift 需要通过bearer token的方式和API进行调用,比如基于Postman就可以了解到,输入bearer token后
但Bearer Token如何获取是个巨大的问题,一般来说有两种方式
1.基于oc命令行,如
[root@master ~]# oc login -u admin Logged into "https://master.example.com:8443" as "admin" using existing credentials. You have access to the following projects and can switch between them with ‘oc project <projectname>‘: * default kube-public kube-service-catalog kube-system management-infra openshift openshift-ansible-service-broker openshift-console openshift-infra openshift-logging openshift-monitoring openshift-node openshift-sdn openshift-template-service-broker openshift-web-console scdf Using project "default". [root@master ~]# oc whoami -t 9GLqCn9yL61TyzRjidM2GRgL-S10z0JSato9Puie70I
2.基于curl命令
[root@node1 ~]# curl -u admin:welcome1 -kv -H "X-CSRF-Token: xxx" ‘https://master.example.com:8443/oauth/authorize?client_id=openshift-challenging-client&response_type=token‘ * About to connect() to master.example.com port 8443 (#0) * Trying 192.168.56.103... * Connected to master.example.com (192.168.56.103) port 8443 (#0) * Initializing NSS with certpath: sql:/etc/pki/nssdb * skipping SSL peer certificate verification * NSS: client certificate not found (nickname not specified) * SSL connection using TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256 * Server certificate: * subject: CN=172.30.0.1 * start date: Nov 30 05:29:38 2018 GMT * expire date: Nov 29 05:29:39 2020 GMT * common name: 172.30.0.1 * issuer: CN=openshift-signer@1543555777 * Server auth using Basic with user ‘admin‘ > GET /oauth/authorize?client_id=openshift-challenging-client&response_type=token HTTP/1.1 > Authorization: Basic YWRtaW46d2VsY29tZTE= > User-Agent: curl/7.29.0 > Host: master.example.com:8443 > Accept: */* > X-CSRF-Token: xxx > < HTTP/1.1 302 Found < Cache-Control: no-cache, no-store, max-age=0, must-revalidate < Expires: Fri, 01 Jan 1990 00:00:00 GMT < Location: https://master.example.com:8443/oauth/token/implicit#access_token=iVwykQc-qqsO245VJ9TIZq_lIL31G1mTM2GJHTPFfkI&expires_in=86400&scope=user%3Afull&token_type=Bearer < Pragma: no-cache < Set-Cookie: ssn=MTU0NDAyNDU1OXxnZV9UaWN5QlpFZ2RULW5vY3o2dVp4SU5WVWZkbWxNd0xfUnFCVzlmRndBSS1Wb2JzY3ZJZHFYb1BPWDNqTWVMV2FjbkJ0bmtlemRMMnpDZ3FSLWUtb0lieVBJQjF0dS1nSWJiZUJrYlFLSngxYVZBa085MUN3VVJkZHJyM2FiNjU1MWkwa3RwcGtHdmJvSmhreWpfRW1MQlFuanYyeEdTcTAybDVuREtEcl9mMHhlXzVYdE5LdG5vNHpKa2QxeGMzczRKRHhzOXzT_k_wyIvwJz72RH5SJor7WYJ3lasYsoVFcdQ6phk75g==; Path=/; HttpOnly; Secure < Date: Wed, 05 Dec 2018 15:42:39 GMT < Content-Length: 0 < * Connection #0 to host master.example.com left intact
一直想通过rest去掉通,尝试很久,最后得到的是如下错误
You have reached this page by following a redirect Location header from an OAuth authorize request. If a response_type=token parameter was passed to the /authorize endpoint, that requested an "Implicit Grant" OAuth flow (see https://tools.ietf.org/html/rfc6749#section-4.2). That flow requires the access token to be returned in the fragment portion of a redirect header. Rather than following the redirect here, you can obtain the access token from the Location header (see https://tools.ietf.org/html/rfc6749#section-4.2.2): 1. Parse the URL in the Location header and extract the fragment portion 2. Parse the fragment using the "application/x-www-form-urlencoded" format 3. The access_token parameter contains the granted OAuth access token
解决办法:
通过运行一个java程序,通过后端的shell去获取,代码如下:
import java.io.InputStreamReader; public class getToken { public void getocpToken() { try { //Process process = Runtime.getRuntime().exec("curl -u admin:welcome1 -kv -H \"X-CSRF-Token: xxx\" ‘https://master.example.com:8443/oauth/authorize?client_id=openshift-challenging-client&response_type=token‘"); Process process = Runtime.getRuntime().exec("/root/curl.sh"); BufferedReader input = new BufferedReader(new InputStreamReader(process.getInputStream())); String line = ""; while ((line = input.readLine()) != null) { System.out.println(line); } input.close(); } catch (Exception e){ e.printStackTrace(); } } public static void main(String[] args) { // TODO Auto-generated method stub getToken sample = new getToken(); sample.getocpToken(); } }
简单说就是调用了curl.sh脚本,这个脚本是长下面这个样的
[root@master ~]# cat curl.sh curl -u admin:welcome1 -kv --silent -H "X-CSRF-Token: xxx" ‘https://master.example.com:8443/oauth/authorize?client_id=openshift-challenging-client&response_type=token‘ 2>&1 | grep access_token | awk -F ‘=‘ ‘{print $2}‘ | awk -F ‘&‘ ‘{print $1}‘
运行结果如下:
[root@master ~]# java getToken
oWcKCjuSfbDaJqbLNeLCP67GuR-lAXmjSPyBplWRbvE
这种方式最大的好处是通过http去获取,这样不需要依赖于oc等命令和环境变量,正是因为通过http,而且用curl,所以也可以进行容器化,在容器中运行。
需要注意事项
一切就很顺利了,贴一下代码
HttpDemo.java

SslUtils.java

好了,有了token,又不需要证书,大家就可以愉快的玩耍了。
