Question

I’ve created a Spring Cloud Config Server with (for now) only two yaml files

application.yml
application-dev.yml

Also Spring Security with basic authentication (username & password) is defined, but curiously I can’t access my configurations except from browser (Chrome & Safari).

Below you can see my configurations.

application.yml

# Basic configs - Name & Profile
spring:
    application:
        name: EMP_CNF-S
    profiles:
      default: ${ENVIRONMENT}

# GitHub Repository (private & SSH)
    cloud:
        config:
            server:
                git:
                    uri: [email protected]:*******/EMP_CNF-S.git
                    ignore-local-ssh-settings: true
                    default-label: ${ENVIRONMENT}
                    private-key: ${GIT_SSH_KEY}
                    search-paths: src/main/resources
                    skip-ssl-validation: true
                    timeout: 10
                    clone-on-start: true

    security:
        user:
            name: ${EMP_CONFIG_USERNAME}
            password: ${EMP_CONFIG_PASSWORD}

# Configuring Port
server:
    port: 8888

# Spring Actuator
management:
    endpoints:
        web:
            exposure:
              include:
                - health
                - info
            base-path: /actuator
    endpoint:
        health:
            show-details: always

Here my application-dev.yml (Every variable value was set due to GitHub Actions & GitHub Secrets)

# Common Configurations - Datasource
 spring:
  datasource:
    url: jdbc:mysql://localhost:3306/
    username: root
    password: *******

  jpa:
    hibernate:
      ddl-auto: update
    show-sql: true

  test:
    database:
      replace: none

# Location Service
  location-service:
    schema: location_db

# Employee Service
  employee-service:
    schema: employee_db

# Customer Service
  customer-service:
    schema: ${EMP_SCHEMA_CUSTOMER}

# Supplier Service
  supplier-service:
    schema: ${EMP_SCHEMA_SUPPLIER}

But when I try to access my environment variables (location_db) I can’t. I do get no result when trying to “curl” it:

curl -u admin:****** http://localhost:8888/location-service/dev

Also in my python script when using module spring-config-client and even with requests library I can’t access the values despite getting a 200 success code. Here a snippet below:

import requests
from requests.auth import HTTPBasicAuth

url = "http://localhost:8888/location-service/dev"
response = requests.get(url=url, auth=HTTPBasicAuth(username='admin', password='******'), headers=headers)

# Print the raw content
print(f"Response status code: {response.status_code}")
print(f"Response text: {response.text}")

# Attempt to parse as JSON
try:
    config = response.json()
    print(config)
except requests.exceptions.JSONDecodeError as e:
    print(f"JSON decode error: {e}")

Output:

Response status code: 200
Response text: <!DOCTYPE html>

    <meta charset="utf-8">

        <p>
          <label for="username" class="sr-only">Username</label>
          <input type="text" id="username" name="username" class="form-control" placeholder="Username" required autofocus>

      </form>
</div>
</body></html>
JSON decode error: Expecting value: line 1 column 1 (char 0)

Here also the usage of spring_config module:

from spring_config import ClientConfigurationBuilder
from spring_config.client import SpringConfigClient

spring_config_username = os.getenv(key = 'EMP_CONFIG_USERNAME')
spring_config_password = '****'

# Build the client configuration
config = (
    ClientConfigurationBuilder()
    .app_name("location-service")               
    .profile("dev")
    .branch('dev')
    .address("http://localhost:8888")
    .authentication((spring_config_username, spring_config_password))  # Set the authentication
    .build()
)

# Create the Spring Config Client
client = SpringConfigClient(config)

And here the (error) output:

  File "/Users/acharrade/.pyenv/versions/3.12.2/lib/python3.12/json/decoder.py", line 355, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
