随用户请求一起从python中的另一个API调用多个API

Question

我是第一次接触Flask API。我已经为我的项目构建了几个API，我通过Postman调用，同时我在Postman主体下传递JSON格式的用户请求。

例如：

@app.route('/data-cleaning', methods=['GET', 'POST'])
def data_cleaning():
    if request.method=='GET':
       user_request = request.get_json()
       ....
       ....
       return X

@app.route('/data-transformation', methods=['GET', 'POST'])
def data_transformation():
    if request.method=='GET':
       user_request = request.get_json()
       ....
       ....
       return X

现在，我在Postman中分别运行这两个服务，在每个服务中，我通过在Postman Body中传递JSON来获取user_request。

现在我想创建另一个API，它可以运行这两个服务以及用户请求。我试图创建下面的脚本，但它在循环中。

@app.route("/app2",methods=['GET', 'POST'])
def app2():
    # requests.get(url, params={})
    if request.method == 'GET':
        res = requests.get("http://127.0.0.1:5000/data-cleaning?table=outage_data", params= 
                                    {"column_name": {"punctuation": "yes","stopwords": "yes", 
                                     "lowercase":"yes","lemetization":"yes"}})
        return print('process completed')

在上面的代码中，我只是尝试从一个API运行另一个API，但实际上我需要运行多个API。

而不是调用GET请求，您应该直接使用带有传递参数实参的data_cleaning()和data_transformation()，否则创建第三个函数并在需要时调用它。

@app.route('/data-cleaning', methods=['GET', 'POST'])
def data_cleaning():
    if request.method=='GET':
       user_request = request.get_json()
       punctuation = user_request.get('punctuation')
       stopwords= user_request.get('stopwords')
       lowercase= user_request.get('lowercase')
       lemetization= user_request.get('lemetization')
       ....
       x = other_services({"column_name": 
                                    {"punctuation": punctuation,
                                    "stopwords": stopwords,  
                                     "lowercase":lowercase,
                                     "lemetization":lemetization}})
       ....
       return x

@app.route('/data-transformation', methods=['GET', 'POST'])
def data_transformation():
    if request.method=='GET':
       user_request = request.get_json()
       punctuation = user_request.get('punctuation')
       stopwords= user_request.get('stopwords')
       lowercase= user_request.get('lowercase')
       lemetization= user_request.get('lemetization')
       ....
       x = other_services({"column_name": 
                                    {"punctuation": punctuation,
                                    "stopwords": stopwords,  
                                     "lowercase":lowercase,
                                     "lemetization":lemetization}})
       ....
       return x



def other_services(column_name=null):
    .....
    ---- some operation ---- 
    .....
    return x
