似乎可以弄清楚为什么在请求参数中通过值循环循环是拆分值
因此，我尝试循环访问 Flask 中 API 参数中存储的值。 我遇到的问题是这些值被打印为单独的字母，而不是返回所有逗号分隔的值。我想知道这是否是因为我不应该将列表传递到我的 API url？
-----------------------------------------------------------------------------------------------
main.py
fruits= ["orange", "apple", "lemon"]
for fruit in fruits:
print(fruit) ---> orange
apple
lemon
response = requests.get(f"127.0.0.1:9000/food?fruits={fruits}")
-----------------------------------------------------------------------------------------------
flask_api.py
from flask import Flask
@app.route('/food', methods=['GET'])
def food():
fruits = request.args.get("fruits")
print(fruits) ---> ["orange", "apple", "lemon"]
for fruit in fruits:
print(fruit) ---> [o r a n g e a p p l e l e m o n]
return fruits
if __name__ == "__main__":
app.run(debug=True, port=9000)
编辑：
这是我在收到回复后修改的代码。
-----------------------
main.py
fruits= ["orange", "apple", "lemon"]
for fruit in fruits:
print(fruit) ---> orange
apple
lemon
response = requests.get(f"127.0.0.1:9000/food", params={"fruits":fruits})
-----------------------------------------------------------------------------------------------
flask_api.py
from flask import Flask
@app.route('/food', methods=['GET'])
def food():
fruits = request.args.get("fruits")
print(fruits) ---> ["orange"]
for fruit in fruits:
print(fruit) ---> [o r a n g e ]
return fruits
if __name__ == "__main__":
app.run(debug=True, port=9000)
So I'm trying to loop through the values stored in an API parameter in Flask.
The issue I'm running into is that the values are getting printed as individual letters, instead of returning all the comma separated values. I was wondering if this was because I'm not supposed to be passing a list to my API url?

main.py
fruits= ["orange", "apple", "lemon"]
for fruit in fruits:
print(fruit) ---> orange
apple
lemon
response = requests.get(f"127.0.0.1:9000/food?fruits={fruits}")
-----------------------------------------------------------------------------------------------
flask_api.py
from flask import Flask
@app.route('/food', methods=['GET'])
def food():
fruits = request.args.get("fruits")
print(fruits) ---> ["orange", "apple", "lemon"]
for fruit in fruits:
print(fruit) ---> [o r a n g e a p p l e l e m o n]
return fruits
if __name__ == "__main__":
app.run(debug=True, port=9000)
Edit:
This is my modified code after getting a response.
-----------------------
main.py
fruits= ["orange", "apple", "lemon"]
for fruit in fruits:
print(fruit) ---> orange
apple
lemon
response = requests.get(f"127.0.0.1:9000/food", params={"fruits":fruits})
-----------------------------------------------------------------------------------------------
flask_api.py
from flask import Flask
@app.route('/food', methods=['GET'])
def food():
fruits = request.args.get("fruits")
print(fruits) ---> ["orange"]
for fruit in fruits:
print(fruit) ---> [o r a n g e ]
return fruits
if __name__ == "__main__":
app.run(debug=True, port=9000)

您注入的参数不正确。这就是您所做的：
这是应该做的：
在第一个示例中，所有水果都作为列表的字符串表示形式发送，在第二个示例中，它们作为单独的查询参数发送。就像普通的请求调用一样：
You are injecting your parameters incorrectly. Here's what you did:
Here's what should have been done:
In the first example, all of the fruits are being sent as a string representation of a list, in the second they are sent as individual query parameters. As just a regular requests call:
