python 中jsonify得到的数据是什么格式列子

jsonify 函数在 Flask 中用于将 Python 对象转换为 JSON 格式的响应。转换后的数据格式为字符串。以下是示例：

from flask import Flask, jsonify

app = Flask(__name__)

@app.route('/')
def hello_world():
    data = {
        "name": "John",
        "age": 30,
        "isMarried": True,
        "hobbies": ["reading", "coding", "playing"],
        "address": {
            "street": "123 Main St",
            "city": "New York",
            "state": "NY"
        }
    }
    return jsonify(data)

if __name__ == '__main__':
    app.run()

当我们访问 http://localhost:5000/ 时，会得到以下响应：

{
  "name": "John",
  "age": 30,
  "isMarried": true,
  "hobbies": ["reading", "coding", "playing"],
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "state": "NY"
  }
}

可以看到，响应的数据格式为 JSON 格式的字符串
