测试插件代码
import json
from flask import Flask, request, jsonify
from typing import Dict, Any
def _(text):
return text
class Result:
"""用于构造响应的 Result 对象。"""
def __init__(self, status: int, message: str, data: Any = None):
self.status = status
self.message = message
self.data = data if data is not None else {}
@staticmethod
def succ(message: str = "", data: Any = None):
return Result(1, message, data)
def set_data(self, data: Dict[str, Any]):
self.data = data
return self
def to_succ_resp(self):
"""返回符合响应结构的字典"""
return {
"status": self.status,
"message": self.message,
"data": self.data
}
app = Flask(__name__)
app.config['JSON_SORT_KEYS'] = False
@app.route('/utils/test2', methods=['POST'])
def test2_resource():
try:
payload = request.get_json()
if payload is None:
return jsonify({"status": 0, "message": "Invalid JSON payload"}), 400
except Exception as e:
return jsonify({"status": 0, "message": f"Error parsing JSON: {e}"}), 400
print(f"/test2 payload is : {json.dumps(payload, ensure_ascii=False, indent=4)}")
extra_params = payload.get("extra_params", {})
# 虽然在纯 Flask 中没有自动的模型校验，但我们仍可以检查 model_name 是否存在
model_name = payload.get("model_name")
if not model_name:
return jsonify({"status": 0, "message": "Missing required field: model_name"}), 400
print(f"extra_params type: {type(extra_params)}, value: {extra_params}")
json_str = json.dumps(extra_params, ensure_ascii=False)
result = Result.succ("").set_data({
"json_str": json_str
})
return jsonify(result.to_succ_resp())
if __name__ == '__main__':
app.run(debug=True, host='0.0.0.0', port=10082)
用curl命令验证
$ curl -X 'POST' \
'http://127.0.0.1:10082/utils/test2' \
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-d '{
"model_name": "string",
"extra_params": {"a":100}
}'
输出信息
{
"data": {
"json_str": "{\"a\": 100}"
},
"message": "",
"status": 1
}
可以看到返回结果 json_str是正常的
但在coze里，在代码的payload处设置断点，却没有传入extra_params对象，导致在coze-studio里看到的插件执行结果是{}
最后附上coze-server的执行日志
