Question

我从python脚本创建了json，这是我为获取json数据而编写的代码：

import requests
import json
import ConfigParser

url = "xxx"

payload = "items.find({ \"repo\": {\"$match\" : \"nswps-*\"}}).include(\"name\",\"repo\",\"path\")\r\n"
headers = {
    'Content-Type': "text/plain",
    'Authorization': "Basic xxxxxxxxx",
    'Accept': "*/*",
    'Cache-Control': "no-cache",
    'Host': "xxxxxx.com",
    'accept-encoding': "gzip, deflate",
    'content-length': "77",
    'Connection': "keep-alive",
    'cache-control': "no-cache"
    }

response = requests.request("POST", url, data=payload, headers=headers)

print(response.text)

上面的代码给了我json文件，它是一个包含多个对象的巨大文件。由于人工制品的某些限制，我无法获得以nswps开头的存储库，但结果是所有存储库名称。 json文件具有如下数据：

"repo" : "npm-remote-cache",
  "path" : "zrender/-",
  "name" : "zrender-4.0.7.tgz"
},{
  "repo" : "npm-remote-cache",
  "path" : "ztree/-",
  "name" : "ztree-3.5.24.tgz"
},{
  "repo" : "nswps-docker-inprogress-local",
  "path" : "ace/core/latest",
  "name" : "manifest.json"
},{
  "repo" : "nswps-docker-inprogress-local",
  "path" : "ace/core/latest",
  "name" : "sha256__0a381222a179dbaef7d1f50914549a84e922162a772ca5346b5f6147d0e5aab4"
},{
.........

现在，我需要创建一个python脚本，以提取其中仅具有nswps值的对象的对象，从上述json可以说，我需要这样的数据：

{
  "repo" : "nswps-docker-inprogress-local",
  "path" : "ace/core/latest",
  "name" : "manifest.json"
},{
  "repo" : "nswps-docker-inprogress-local",
  "path" : "ace/core/latest",
  "name" : "sha256__0a381222a179dbaef7d1f50914549a84e922162a772ca5346b5f6147d0e5aab4"
}

Answer 1

我可以在@furas的帮助下成功完成此操作，再次感谢！解决方案代码如下：

response = requests.request("POST", url, data=payload, headers=headers)
 list = response.text
 data = response.json()['results']
 print("Line#24")
output_dict = [items for items in data if 'nswps' in items['repo']]

使用

data = response.json()

您应该将JSON转换为Python的列表

假设您有data

data = [
    {"repo" : "npm-remote-cache",
      "path" : "zrender/-",
      "name" : "zrender-4.0.7.tgz"
    },{
      "repo" : "npm-remote-cache",
      "path" : "ztree/-",
      "name" : "ztree-3.5.24.tgz"
    },{
      "repo" : "nswps-docker-inprogress-local",
      "path" : "ace/core/latest",
      "name" : "manifest.json"
    },{
      "repo" : "nswps-docker-inprogress-local",
      "path" : "ace/core/latest",
      "name" : "sha256__0a381222a179dbaef7d1f50914549a84e922162a772ca5346b5f6147d0e5aab4"
    }
]

然后您可以使用for循环检查列表中的每个项目并仅选择其中一些

for item in data:
    if item['repo'].startswith('nswps'):
        print(item)

并作为列表理解

selected = [item for item in data if item['repo'].startswith('nswps')]

使用python脚本解析Json文件中的数据
