PokeAPI & Flask：在 API 上组合不同的属性

Question

API初学者，

我正在创建一个 API，它使用一个 ENDPOINT 调用角色名称及其描述。到目前为止，我的数据出现在不同的端点。

目标：使输出格式 ('http://127.0.0.1:5000/v1/pokemon/string:name') 看起来类似于：

{ "name": "pichu", "description": "还不擅长储存electricity.It 被逗乐或受惊可能会发出震动。"}

from flask import Flask, jsonify, Response
from flask_restful import Resource, Api, fields, marshal_with
import requests, json

app = Flask(__name__)
api = Api(app)

# Prints all Pokemon via JSON
@app.route('/v1/pokemon/all', methods=['GET'])
def poke_names():
    data = []
    name_url = "https://pokeapi.co/api/v2/pokemon?limit=151"
    while True:
        resp = requests.get(name_url)
        json = resp.json()
        data.extend(json.get('results', []))
        name_url = json.get('next')
        if not name_url: break
    return jsonify(data)


@app.route('/v1/pokemon/<string:name>/title', methods=['GET'])
def get_poke(name):
     return jsonify({'name': name})


#flavor Text ie pokemon description
@app.route('/v1/pokemon/<int:pokemon_id>', methods=['GET'])
def get_description(pokemon_id):
    descrip_url = f"https://pokeapi.co/api/v2/pokemon-species/{pokemon_id}"
    r = requests.get(descrip_url)
    json_blob = r.json()
    flav_text = extract_descriptive_text(json_blob)
    return jsonify({'description': flav_text})


def extract_descriptive_text(json_blob, language='en'):
    text = []
    for f in json_blob['flavor_text_entries']:
        if f['language']['name'] == language:
            text.append(f['flavor_text'])
    return text


#error occurs below
@app.route('/v1/pokemon/<string:name>')
def all_poke_data(name, flav_text):
    return jsonify({'name':name, 'description':flav_text})


if __name__ == "__main__":
    app.run(debug=True)

错误：当我尝试组合它们时我得到

TypeError: all_poke_data() missing 1 required positional argument: 'flav_text'

感谢您的指点！

想通了！

添加这个功能就可以了，它是两个路由功能的结合

@app.route('/v1/pokemon/<string:name>')
def get_poke(name):
    descrip_url = f"https://pokeapi.co/api/v2/pokemon-species/{name}"
    r = requests.get(descrip_url)
    json_blob = r.json()
    flav_text = extract_descriptive_text(json_blob)
    return jsonify({'name': name},{'description': flav_text})
