无法通过Python及Curl访问Spring Cloud Config服务的问题

我搭建了一个Spring Cloud Config Server，目前包含两个yaml文件：

• application.yml
• application-dev.yml

已配置基于用户名密码的Spring Security基础认证，但出现异常：只有Chrome和Safari浏览器能正常访问配置信息，curl命令、Python脚本（requests库或spring-config-client模块）均无法获取配置。

配置文件内容 #

application.yml #

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

                git:
                    uri: git@github.com:*******/EMP_CNF-S.git
                    ignore-local-ssh-settings: true
                    default-label: ${ENVIRONMENT}
                    private-key: ${GIT_SSH_KEY}

                    clone-on-start: true

    security:

            password: ${EMP_CONFIG_PASSWORD}

application-dev.yml #

（所有变量值已通过GitHub Actions和GitHub Secrets设置）

# 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}

测试情况 #

尝试访问location-service的dev环境配置时失败：

curl命令测试 #

执行命令：

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

无法获取预期配置结果。

Python requests库测试 #

代码片段：

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}")

输出结果：

Response status code: 200

Python spring-config-client模块测试 #

代码片段：

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)

错误输出：

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)
