Question

我正在尝试在google colab中运行此代码，但是却收到“ HTTP错误403：禁止访问”：

{
  "name": "samplerouting",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "android": "react-native run-android",
    "ios": "react-native run-ios",
    "start": "react-native start",
    "test": "jest",
    "lint": "eslint ."
  },
  "dependencies": {
    "@react-native-community/masked-view": "^0.1.6",
    "@react-navigation/native": "^5.0.0",
    "react": "16.9.0",
    "react-native": "0.61.5",
    "react-native-gesture-handler": "^1.5.6",
    "react-native-reanimated": "^1.7.0",
    "react-native-safe-area-context": "^0.7.2",
    "react-native-screens": "^2.0.0-beta.2"
  },
  "devDependencies": {
    "@babel/core": "7.8.4",
    "@babel/runtime": "7.8.4",
    "@react-native-community/eslint-config": "0.0.5",
    "babel-jest": "24.9.0",
    "eslint": "6.8.0",
    "jest": "24.9.0",
    "metro-react-native-babel-preset": "0.56.4",
    "react-test-renderer": "16.9.0"
  },
  "jest": {
    "preset": "react-native"
  }
}

import six.moves.urllib as urllib
try:
    import urllib.request
except ImportError:
    raise ImportError('You should use Python 3.x')

if not os.path.exists('./RoadDamageDataset.tar.gz'):
    url_base = 'https://s3-ap-northeast-1.amazonaws.com/mycityreport/RoadDamageDataset.tar.gz'
    urllib.request.urlretrieve(url_base, './RoadDamageDataset.tar.gz')

    print("Download RoadDamageDataset.tar.gz Done")

else:
    print("You have RoadDamageDataset.tar.gz")

任何帮助将不胜感激。（链接到Google驱动器中的代码：https://drive.google.com/file/d/1C-_DBepoJFL5HztTyYx9uNG22_MJB5Bo/view?usp=sharing）

我自由地修改了主题行：您要问的主要问题是“如何解决“ HTTP 403：禁止”错误？”。我还自由地修改了标签：您的语言是Python；您正在导入“六个”库，并且正在使用Google Colaboratory。

无论如何：

https://en.wikipedia.org/wiki/HTTP_403

HTTP 403 提供了与HTTP 401不同的错误情况；而HTTP 401 如果客户端未通过身份验证，则返回，并暗示有效的验证后，可能会返回成功的响应，如果不允许客户端访问HTTP 403，则会返回HTTP 403 尽管提供了身份验证（例如身份验证不足）身份验证帐户的权限。

请记住，Web服务器（此处为Google Colab）在某些“用户”的上下文中运行。我猜测您的文件（RoadDamageDataset.tar.gz）可能对该网络用户没有读取权限。

建议：确认/RoadDamageDataset.tar.gz拥有“读取”权限。

而且，这看起来是错误的：

url_base = 'https://s3-ap-northeast-1.amazonaws.com/mycityreport/RoadDamageDataset.tar.gz'
    urllib.request.urlretrieve(url_base, './RoadDamageDataset.tar.gz')

建议：尝试将其更改为https://s3-ap-northeast-1.amazonaws.com/mycityreport
