返回 HTTP json 響應

Question

我是使用 python 開發 REST API 的新手。 我想將此列表返回為 json 作為響應。 我使用來自 sanic 的響應。

response_data = [{'error': False, 'errormsg': '', 'status': '200'}, {'data': {1: {'name': 'sosialisasi', 'm_value': 77, 'c_value': 876, 'cu_value': 568, 'cl_value': 468, 'independent_vars': {'jumlah hari': {None: {'val_name': None, 'value': None}}, 'tingkatan sosialisasi': {2: {'val_name': 'kecamatan', 'value': '0.5'}, 1: {'val_name': 'kabupaten', 'value': '0.75'}}}}}}]

response.json(response_data, 200)

但我收到錯誤TypeError: expected bytes, str found

Traceback (most recent call last):


File "/home/dewi/saniccrudenv/lib/python3.8/site-packages/sanic/app.py", line 939, in handle_request
    response = await response
  File "/home/dewi/anomali/operations.py", line 183, in getAsb
    return response.json(response_data, 200)
  File "/home/dewi/saniccrudenv/lib/python3.8/site-packages/sanic/response.py", line 210, in json
    dumps(body, **kwargs),
TypeError: expected bytes, str found

我的代碼有問題嗎？ 當我在 response_data 上使用 json.dumps 時，這不是錯誤。 但它會像這樣返回 json 字符串

"[{\"error\": false, \"errormsg\": \"\", \"status\": \"200\"}, {\"data\": {\"1\": {\"name\": \"sosialisasi\", \"m_value\": 77, \"c_value\": 876, \"cu_value\": 568, \"cl_value\": 468, \"independent_vars\": {\"jumlah hari\": {\"null\": {\"val_name\": null, \"value\": null}}, \"tingkatan sosialisasi\": {\"2\": {\"val_name\": \"kecamatan\", \"value\": \"0.5\"}, \"1\": {\"val_name\": \"kabupaten\", \"value\": \"0.75\"}}}}}}]"

我想要的是json object，像這樣

[
{
    "error": false,
    "errormsg": "",
    "status": "200"
},
{
    "data": [
        {
            "id": 1,
            "nama": "test1",
            "kode": "101"
        },
        {
            "id": 2,
            "nama": "test2",
            "kode": "202"
        }
    ]
}

]

問題是您將None作為關鍵字：

response_data = [
        {"error": False, "errormsg": "", "status": "200"},
        {
            "data": {
                1: {
                    "name": "sosialisasi",
                    "m_value": 77,
                    "c_value": 876,
                    "cu_value": 568,
                    "cl_value": 468,
                    "independent_vars": {
                        "jumlah hari": {
                            None: {"val_name": None, "value": None}
                        },
                        "tingkatan sosialisasi": {
                            2: {"val_name": "kecamatan", "value": "0.5"},
                            1: {"val_name": "kabupaten", "value": "0.75"},
                        },
                    },
                }
            }
        },
    ]

如果你改變：

"jumlah hari": {
    None: {"val_name": None, "value": None}
},

至

"jumlah hari": {
    "None": {"val_name": None, "value": None}
},

它將按預期工作。

[{"error":false,"errormsg":"","status":"200"},{"data":{"1":{"name":"sosialisasi","m_value":77,"c_value":876,"cu_value":568,"cl_value":468,"independent_vars":{"jumlah hari":{"None":{"val_name":null,"value":null}},"tingkatan sosialisasi":{"2":{"val_name":"kecamatan","value":"0.5"},"1":{"val_name":"kabupaten","value":"0.75"}}}}}}]

JSON 規格：

object 結構表示為一對圍繞零個或多個名稱/值對的花括號標記。 名稱是一個字符串。
