FastAPI 定义全局变量并实现通过接口改变全局变量_fastapi 全局变量

1.直接在main.py函数中定义全局变量：

app = FastAPI()
data_type = 1
model_path = "path"
data_path = 'path'
shap_values_path = 'path'

2. 使用接口改变全局变量

@app.post('/change_global_data')
async def data_test(path: Change_data):
    param = path.dict()
    change_model_path = param['model_path']
    change_data_path = param['data_path']
    change_shap_value_path = param['shap_value_path']
    try:
        global model_path , data_path, shap_value_path
        model_path  = change_model_path 
        data_path = change_data_path 
        shap_value_path = change_shap_value_path 
        return {'status': True, 'msg': 'Success'}, 400
    except Exception as e:
        LOGGER.error(e)
        return {'status': False, 'msg': e}, 400
