Question

我正在尝试使用Socrata Metadata API通过python更新我的整个元数据资产库存。使用Metadata Api Docs中的python代码示例，我能够读取元数据，但由于错误403，即使使用正确的身份验证，我也无法更新它。我有管理员访问权限，访问秘密令牌和app令牌。我试图使用OAuth2和基本身份验证都无济于事。这是一个快速代码示例：

from urllib2 import Request, urlopen

values = """
  {
    "name": "Business Entities in Colorado_TEST",
  }
"""

headers = {
  'X-Socrata-Host': 'data.colorado.gov',
  'Content-Type': 'application/json',
  'Authorization': 'OAuth {REDACTED}'
}
request = Request('https://data.colorado.gov/api/views/metadata/v1/4eit-nuxn', data=values, headers=headers)
request.get_method = lambda: 'PATCH'

response_body = urlopen(request).read()
print response_body

其中{REDACTED}等于App Token减少花括号。代替授权＆＃39;我也尝试了X-App-Token＆＃39;无济于事。我觉得这是一个非常基本的修复，但我肯定错过了一些东西。

我还试图使用：

输入base64字符串

username = '{REDACTED}'
password = '{REDACTED}'
base64string = base64.encodestring('%s:%s' % (username, password)).replace('\n', '')

将变量base64string添加到我的标题中并遇到了同样的问题。基于：Update a Socrata dataset using app token and private in HTTP basic

如果有任何帮助，请点击我的追溯：

谢谢！

如果您正在使用HTTP基本身份验证，看起来您基于第二个代码示例，则需要在标头中使用Basic授权类型而不是OAuth。例如：

headers = {
  'Content-Type': 'application/json',
  'X-Socrata-Host': 'data.colorado.gov',
  'Content-Type': 'application/json',
  'Authorization': 'Basic {REDACTED}'
}

我修复了身份验证错误，并通过在Python 3上使用请求而不是使用urllib2来完成此操作。这是我更新的代码

#!/usr/bin/python
#coding: utf-8
import base64
import json
import requests

username = '{REDACTED}'
password = '{REDACTED}'
string = '%s:%s' % (username, password)
base64string = base64.b64encode(string.encode())
app_token = '{REDACTED}'

values = """
{
  "metadata" : {
    "id" : "TEST",
    "name" : "Business Entities_TEST"
  }
}
"""

headers = {
  'Accept': '*/*',  
  'X-Socrata-Host': 'data.colorado.gov',
  'Content-Type': 'application/json',
  'Authorization': 'Basic {REDACTED}',
  'X-App-Token': app_token
}

request = requests.get('https://data.colorado.gov/api/views/metadata/v1/4ykn-tg5h', data=values, headers=headers)
request.get_method = lambda: 'PATCH'

response_body = request.json()
print(response_body)
