Python 如何从具有多个过滤器的API查询JSON数据？

我正在从JSON API检索数据。
数据由应用程序列表组成，每个应用程序都有许多属性。
我只想要与

query\u input

匹配且不受信任的应用程序（请参见API文档图片）： 我想要两者的交叉点。我只想要符合这两个条件的应用程序。如果我使用：

parameters = {"query" : query_input, "trusted" : "false", "limit" : 3}
request = requests.get("http://(certain api link)", params = parameters)
print(json.dumps(request.json(), indent = 4))

如果我使用上面的代码，并将

query\u input

设置为“facebook”，我会得到以下结果：

                }
            }
        ]
    }
}

这有点奏效。
我得到与facebook相关的应用程序，因为

“limit”：3

，它只显示3个应用程序（所有应用程序都在“数据列表”>“列表”中，每个应用程序都以“id”开头，以“billing”结尾）。

---

我应该只得到恶意软件排名为“未知”的应用程序，但我得到的是恶意软件排名为“受信任”的应用程序，这是我不想要的。

API文档将

false

列为

TRUSTED

的JSON布尔值，因此在Python中应该使用

false

的布尔值，而不是字符串值

“false”

，服务器会将其视为真实值而不是虚假值：

parameters = {"query" : query_input, "trusted" : False, "limit" : 3}

---

我认为文档有点误导。如果您将trusted参数设置为true，它将

仅列出受信任的应用程序

。如果将其设置为false，则所有应用程序都将受信任且未知

没有选项只能从源获取未知应用

我尝试了对Facebook的查询，所有应用都返回为受信任的。这可能是因为没有来自该来源的不受信任/未知应用。 使用

terrarium

进行检查作为查询，您可以使用

trusted=false

获得一些未知的信任级别，然后在

trusted=true

因此，看起来您需要手动获取所有结果，然后在恶意软件排名不等于受信任的情况下筛选词典

app_data = request.json()
untrusted = [app_entry for app_entry in app_data['datalist']['list'] if app_entry['file']['malware']['rank'].upper() != 'TRUSTED']

---

很高兴我能帮忙：）只有一件事……如果我省略了链接，你是如何“尝试Facebook查询”的？
