结论: ✅ Ollama API 正常响应
🚀 执行步骤和实际结果
步骤 1: 创建 Ollama 客户端模块
文件: backend/ollama_client.py (约 500 行)
功能实现:
- ✅ 异步 HTTP 客户端(httpx)
- ✅ 语音情感分析 (
analyze_voice_emotion) - ✅ 文本情感分析 (
analyze_text_sentiment) - ✅ 风险评分计算 (
calculate_risk_score) - ✅ Fallback 机制(Ollama 不可用时使用关键词分析)
- ✅ JSON 响应解析(支持 ```json 和纯 JSON)
- ✅ 单例模式客户端管理
关键实现:
class OllamaClient:
def __init__(self, base_url: str = OLLAMA_BASE_URL, model: str = OLLAMA_MODEL):
self.base_url = base_url # http://localhost:11434
self.model = model # lingjingwanxiang:32b
self.client = httpx.AsyncClient(timeout=120.0)
async def analyze_voice_emotion(
self, transcript: str, duration_seconds: float, ...
) -> Dict[str, Any]:
"""语音情感分析,返回 emotion, confidence, sentiment_score"""
# 使用 Ollama 生成分析
async def analyze_text_sentiment(
self, content: str, context: Optional[str] = None
) -> Dict[str, Any]:
"""文本情感分析,返回 sentiment, keywords, risk_indicators"""
# 使用 Ollama 生成分析
async def calculate_risk_score(
self, voice_emotions: List[str], text_sentiments: List[str], ...
) -> Dict[str, Any]:
"""综合风险评分,返回 risk_score, risk_category, recommendations"""
# 使用 Ollama 生成评分
验证结果: ✅ 模块创建成功
步骤 2: 替换 backend/api/data.py 中的 mock 函数
变更内容:
删除:
mock_analyze_voice()- 随机生成的 mock 语音分析
新增:
analyze_voice_with_ollama()- 真实的 Ollama 语音分析
变更前:
def mock_analyze_voice(file_url: str, duration_seconds: float) -> dict:
emotions = ["happy", "neutral", "sad", "anxious", "angry"]
emotion = random.choice(emotions)
return {
"transcript": "我今天很想爸爸妈妈..." if emotion != "happy" else "今天很开心!",
"emotion": emotion,
"emotion_confidence": round(random.uniform(0.70, 0.95), 2),
...
}
变更后:
async def analyze_voice_with_ollama(file_url: str, duration_seconds: float) -> dict:
from backend.ollama_client import get_ollama_client
transcript = random.choice(transcripts) # TODO: 真实语音转文字
ollama = await get_ollama_client()
analysis = await ollama.analyze_voice_emotion(
transcript=transcript,
duration_seconds=duration_seconds,
audio_quality_score=0.85
)
return {
"transcript": transcript,
"emotion": analysis["emotion"],
"emotion_confidence": analysis["emotion_confidence"],
"sentiment_score": analysis["sentiment_score"],
...
}
删除:
mock_analyze_text()- 关键词匹配的 mock 文本分析
新增:
analyze_text_with_ollama()- 真实的 Ollama 文本分析
调用点更新:
# 语音分析调用(data.py:362)
analysis = await analyze_voice_with_ollama(file_url, duration_seconds)
# 文本分析调用(data.py:452)
analysis = await analyze_text_with_ollama(request.content, context=request.source)
验证结果: ✅ 函数替换成功
步骤 3: 替换 backend/api/risk_assessments.py 中的 mock 函数
变更内容:
删除:
mock_calculate_risk_score()- 随机生成的 mock 风险评分
新增:
calculate_risk_score_with_ollama()- 真实的 Ollama 风险评分
变更前:
def mock_calculate_risk_score(voice_data_ids: List[str], text_data_ids: List[str]) -> Dict:
risk_score = random.randint(15, 95)
if risk_score <= 25:
risk_category = "low"
elif risk_score <= 50:
risk_category = "medium"
...
变更后:
async def calculate_risk_score_with_ollama(
voice_data_ids: List[str],
text_data_ids: List[str],
session: AsyncSession
) -> Dict[str, Any]:
# 从数据库获取语音和文本数据
voice_emotions = []
if voice_data_ids:
stmt = select(VoiceData).where(VoiceData.id.in_(voice_data_ids))
result = await session.execute(stmt)
voice_data_list = result.scalars().all()
voice_emotions = [vd.emotion for vd in voice_data_list if vd.emotion]
# 使用 Ollama 计算风险
ollama = await get_ollama_client()
risk_analysis = await ollama.calculate_risk_score(
voice_emotions=voice_emotions,
text_sentiments=text_sentiments,
risk_indicators_count=risk_indicators_count
)
...
调用点更新:
# 风险评分调用(risk_assessments.py:269)
assessment_result = await calculate_risk_score_with_ollama(
voice_data_ids, text_data_ids, session
)
验证结果: ✅ 函数替换成功
步骤 4: 更新 backend/main.py 添加 Ollama 生命周期管理
变更内容:
startup_event 更新:
@app.on_event("startup")
async def startup_event():
from backend.redis_client import get_redis_client
from backend.ollama_client import get_ollama_client
try:
await get_redis_client()
logger.info("✅ Redis connection established")
except Exception as e:
logger.error(f"❌ Redis initialization failed: {str(e)}")
try:
await get_ollama_client()
logger.info("✅ Ollama AI client initialized (lingjingwanxiang:32b)")
except Exception as e:
logger.error(f"❌ Ollama initialization failed: {str(e)}")
logger.info("🚀 Application startup complete")
shutdown_event 更新:
@app.on_event("shutdown")
async def shutdown_event():
from backend.redis_client import close_redis
from backend.ollama_client import close_ollama
try:
await close_redis()
logger.info("✅ Redis connection closed")
except Exception as e:
logger.warning(f"⚠️ Redis shutdown error: {str(e)}")
try:
await close_ollama()
logger.info("✅ Ollama client closed")
except Exception as e:
logger.warning(f"⚠️ Ollama shutdown error: {str(e)}")
logger.info("👋 Application shutdown complete")
验证结果: ✅ 生命周期管理添加成功
步骤 5: 安装依赖
已有依赖:
$ grep "^httpx" requirements.txt
httpx==0.26.0
安装到虚拟环境:
$ source venv/bin/activate
$ pip install httpx==0.26.0
Successfully installed anyio-4.12.0 certifi-2025.11.12 h11-0.16.0
httpcore-1.0.9 httpx-0.26.0 idna-3.11 sniffio-1.3.1
验证结果: ✅ 依赖安装成功
步骤 6: 创建测试脚本
文件: scripts/test_ollama.py (约 350 行)
测试用例:
- ✅ Ollama 服务可用性测试
- ✅ 语音情感分析测试(2 个测试用例)
- ✅ 文本情感分析测试(3 个测试用例)
- ✅ 风险评分计算测试(3 个测试用例)
使用方法:

⚠️ 遗留问题
问题 1: 语音转文字仍使用 mock
描述: 当前语音分析仍使用随机选择的 mock 转录文本,未实现真实的语音转文字
影响: 无法分析真实上传的音频文件
计划:
- 选项 1: 集成 OpenAI Whisper(本地部署)
- 选项 2: 使用 Alibaba Cloud ISI(云服务)
- 选项 3: 使用其他开源 STT 模型
问题 2: Ollama 推理速度
描述: 32B 模型推理较慢(2-5 秒),可能影响用户体验
当前缓解措施:
- 设置 120 秒超时
- 实现 fallback 机制
- 异步处理,不阻塞主线程
未来优化:
- 考虑使用更小的模型(如 7B/13B)
- 实现模型响应缓存
- 批量处理请求
问题 3: 模型版本管理
描述: 当前硬编码模型名称 lingjingwanxiang:32b,未实现版本切换
计划:
- 添加环境变量配置
OLLAMA_MODEL - 支持多模型切换
- 记录模型版本到评估结果
