result = json.dumps(request.form) result = jsonify(request.form) but result still be the same.结果 = json.dumps(request.form) 结果 = jsonify(request.form) 但结果仍然相同。 HTML form Output Json HTML 形式 Output Json

Is there any way to get the result like this { "department": "sales", "donation": 1538, "firstName": "abc", "lastName": "ccc" }有没有办法得到这样的结果 { "department": "sales", "donation": 1538, "firstName": "abc", "lastName": "ccc" }

Taking notes from this Answer Here从这里的答案中记笔记

JSON is untyped. JSON 无类型。 Anything sent in JSON format will be converted to a string;以 JSON 格式发送的任何内容都将转换为字符串； so its not possible to send the donation value as an integer.因此无法将donation值作为 integer 发送。
