如何在Lambda中使用Python 3.9的'requests.get'函数。

Question

【以下的问题经过翻译处理】你好，我需要通过GeoLite2 Country网络服务从IP地址获取国家信息。需要使用以下'curl'命令。curl -u "{account_id}:{license_key}" "https://geolite.info/geoip/v2.1/country/{ip_address}?pretty" *参考URL https://dev.maxmind.com/geoip/geolocate-an-ip/web-services?lang=en#command-line-curl-examples 但是Python没有'curl'命令，所以我需要使用'requests.get'命令。我测试了以下代码。（3.112.189.172是日本的IP地址。） <> import requests import os def lambda_handler(event, context): response = requests.get('https://geolite.info/geoip/v2.1/country/3.112.189.172?pretty', auth=('account_id', 'license_key')) return response.json() <<运行code1时的结果。>> { "continent": { "code": "AS", "geoname_id": 6255147, "names": { "zh-CN": "亚洲", "de": "Asien", "en": "Asia", "es": "Asia", "fr": "Asie", "ja": "アジア", "pt-BR": "Ásia", "ru": "Азия" } }, "country": { "iso_code": "JP", "geoname_id": 1861060, "names": { "ja": "日本", "pt-BR": "Japão", "ru": "Япония", "zh-CN": "日本", "de": "Japan", "en": "Japan", "es": "Japón", "fr": "Japon" } }, "registered_country": { "iso_code": "US", "geoname_id": 6252001, "names": { "ru": "США", "zh-CN": "美国", "de": "Vereinigte Staaten", "en": "United States", "es": "Estados Unidos", "fr": "États Unis", "ja": "アメリカ", "pt-BR": "EUA" } }, "traits": { "ip_address": "3.112.189.172", "network": "3.112.0.0/14" } } 如果我将变量'url'用作'requests.get'的参数， <> import requests import os def lambda_handler(event, context): url = "'https://geolite.info/geoip/v2.1/country/3.112.189.172?pretty', auth=('account_id', 'license_key')" response = requests.get(url) <

【以下的回答经过翻译处理】 我解决了这个问题。

我发现这个API使用了基本身份验证。用户名是'account_id'，密码是'license_key'。所以我使用了'requests.auth.HTTPBasicAuth'。

以下是代码：
```
url1 = "https://geolite.info/geoip/v2.1/country/"
ip = os.environ['ip']
url2 ="?pretty"
url3 = url1 + ip +url2
account_id = os.environ['account_id']
license_key = os.environ['license_key']

r = requests.get(url3, auth=requests.auth.HTTPBasicAuth(account_id, license_key))

country = r.json()["country"]["names"]["ja"]
return(country)
```
这个代码可以正常工作。
