透過 REST 介面取得客戶端時，Keycloak 傳回 {"error":"Bearer token format error"}

透過 REST 介面取得客戶端時，Keycloak 傳回 {"error":"Bearer token format error"}

尋找一種方法來設定 keycloak 環境，建立一個新領域並填充客戶端/用戶，以使用 REST/CURL 介面取得最小 OAuth 端點。

Keycloak 回傳 {"error":"承載令牌格式錯誤"}

我使用的是 Windows 10 Pro + Docker

我甚至沒有從大師領域獲取客戶名單。

我按照以下記錄進行操作：

“keycloak-documentation/server_development/topics/admin-rest-api.adoc”
。
還有：

“取得屬於該領域的客戶端 (GET /{realm}/clients)”
。
“授權：持有者 eyJhbGciOiJSUz...”
。
“Keycloak 角色是如何管理的？” 。

作為達到的方式：

透過 REST /auth/admin/realms 建立領域
。
腳本本身：

    mkdir test
    cd test
    npm install -g underscore-cli
    docker run --name keyclk01 -e KEYCLOAK_USER=admuser -e KEYCLOAK_PASSWORD=admpass -p 8444:8443 -p 8081:8080 -p 9991:9990 jboss/keycloak
    docker restart keyclk01
    docker inspect --format "{{.NetworkSettings.IPAddress}}" keyclk01
    curl --proxy 127.0.0.1:8888 -k --url https://127.0.0.1:8444/auth/realms/master/protocol/openid-connect/token -d "username=admuser&password=admpass&client_id=admin-cli&grant_type=password" > 01Raw.json

答案1

我完全按照你的描述進行操作，但我使用 Python 來解析 JSON。這是我所做的：

ACCESS_TOKEN=$(curl -s -k -d 'client_id=admin-cli' \
                          -d 'username=admin' \
                          -d "password=$KEYCLOAK_PW" \
                          -d 'grant_type=password' \
                         "https://${KEYCLOAK_SERVER}/auth/realms/master/protocol/openid-connect/token" | python -c '
import json,sys;keycloak_data=json.load(sys.stdin);print keycloak_data["access_token"]')

創建領域：

cat <<! | curl -k -s \
        -X POST \
        -H "Content-Type: application/json" \
        -H "Authorization: bearer $ACCESS_TOKEN" \
        --data-binary @- "https://${KEYCLOAK_SERVER}/auth/admin/realms"
{"enabled":true,"id":"myrealm","realm":"myrealm"}
!

在客戶端添加

cat <<! | curl -s -k \
        -X POST \
        -H "Content-Type: application/json" \
        -H "Authorization: bearer $ACCESS_TOKEN" \
        --data-binary @- "https://${KEYCLOAK_SERVER}/auth/admin/realms/myrealm/clients"
{
                "clientId": "$INSTANCE_NAME",
                "clientAuthenticatorType": "client-secret",
                "protocol": "openid-connect",
                "fullScopeAllowed": false,
                "authorizationServicesEnabled": true,
                "serviceAccountsEnabled": true,
                "redirectUris" : [ "https://$INSTANCE/*" ],
                "publicClient": false,
                "enabled": true
                }
}
!

檢索 CLIENT_ID

CLIENT_ID=$(curl -s -k \
        -X GET \
        -H "Content-Type: application/json" \
        -H "Authorization: bearer $ACCESS_TOKEN" \
        "https://${KEYCLOAK_SERVER}/auth/admin/realms/myrealm/clients" | python -c '
import json,sys,os;keycloak_data=json.load(sys.stdin)
CLIENTID=os.environ["INSTANCE_NAME"]
for c in keycloak_data:
    if c["clientId"]==CLIENTID:
        print c["id"]
        sys.exit()
')

如果您仍然需要它，或者其他人需要它，這也許會有所幫助。

答案2

Keycloak 專案幾乎已經停止，他們現在擁有專有的身份存取管理（IAM）。

Keycloak 本身總是被破壞，許多 REST 端點無法運作並傳回無意義的回應，正如您自己看到的那樣，即使嚴格遵循文件也是如此。

答案是，因為 Keycloak 已損壞，即使遵循文件也不可能執行您想要的操作。

我的建議是你嘗試你能找到的替代方案這裡。
