如何在 python 中返回 json 块

Question

我正在尝试编写一个快速的 api ，它将搜索 json object 并返回当前帐户（如果 iban 相同）。 如果它没有找到任何 iban，它应该返回 404。

这是我到目前为止所拥有的：

from flask import Flask
from flask import request
from flask import abort
import json

app = Flask(__name__)

accounts = {
    "accounts": {
        "account": {
            "naam": "Mark Roording",
            "iban": "NL93RABO4923460458",
            "straat": "Pluviusstraat",
            "straatnummer": 5,
            "postcode": "7321EL",
            "plaats": "Apeldoorn"
        },
        "account": {
            "naam": "Carleen van der Snoek",
            "iban": "NL80INGB7619798757",
            "straat": "Franciscanenstraat",
            "straatnummer": 160,
            "postcode": "1566LC",
            "plaats": "Assendelft"
        },
        "account": {
            "naam": "Maria Lingen",
            "iban": "NL28INGB6291533782",
            "straat": "Weterschoten",
            "straatnummer": 135,
            "postcode": "7381AL",
            "plaats": "Klarenbeek"
        },
        "account": {
            "naam": "Betty Kelder",
            "iban": "NL70INGB6143537119",
            "straat": "Utrechtseweg",
            "straatnummer": 111,
            "postcode": "6862AC",
            "plaats": "Oosterbeek"
        },
        "account": {
            "naam": "Timmie Ruijgrok",
            "iban": "NL41ABNA9079565997",
            "straat": "Kuipersstraat",
            "straatnummer": 27,
            "postcode": "1074EK",
            "plaats": "Amsterdam"
        }
    }

}


@app.route('/get_accountdetails')
def get_accountdetails():
    paramiban = request.args.get('iban', type=str)

    for k, acctinfo in accounts['accounts'].items():
        if acctinfo['iban'] == paramiban:
            response = app.response_class(
                response=json.dumps(acctinfo),
                status=200,
                mimetype='application/json'
            )

            return response
        else:
            return abort(404)

因此，如果 iban 是 NL28INGB6291533782 它将返回当前帐户和 200，如下所示：

{"naam": "Maria Lingen", "iban": "NL28INGB6291533782", "straat": "Weterschoten", "straatnummer": 135, "postcode": "7381AL", "plaats": "Klarenbeek"}

编辑：所以我更改了代码，如果我输入最后一个 iban，它会起作用并返回值。 如果是其他iban，则不起作用。

Answer 1

from flask import json

@app.route('/get_accountdetails')
def get_accountdetails():
    iban = request.args.get('iban')

    for dict in accounts:
        if dict['iban'] == iban:
            response = app.response_class(
                 response=json.dumps(dict['account']),
                 status=200,
                 mimetype='application/json'
               )
            return response
        else:
            return abort(404)

它将有助于发送带有 200 状态码的 json 响应。

Answer 2

您处理帐户，而您应该处理帐户["accounts"]：

iban = 'NL41ABNA9079565997'
for k, acctinfo in accounts['accounts'].items():
    if acctinfo['iban'] == iban:
        print(acctinfo)

印刷：

    {
  "naam": "Timmie Ruijgrok",
  "iban": "NL41ABNA9079565997",
  "straat": "Kuipersstraat",
  "straatnummer": 27,
  "postcode": "1074EK",
  "plaats": "Amsterdam"
}
