需要在字符串哈希值中格式化转义符号

Question

我正在使用一个 YAML 文件，当我将其转换为哈希时，其中一个值是字符串。

这是我正在使用的文档：

---
    http_interactions:
    - request:
        method: post
        uri: http://********/client/api
        body:
          encoding: US-ASCII
          string: *******************
        headers: {}
      response:
        status:
          code: 200
          message: OK
        headers:
          Date:
          - Mon, 24 Sep 2012 10:38:01 GMT
          Set-Cookie:
          - ***************; Path=/client
          Content-Type:
          - text/javascript;charset=UTF-8
          Content-Length:
          - "425"
        body:
          encoding: ASCII-8BIT
          string: >
            {
              "loginresponse": {
                "timeout": "43200",
                "lastname": "frgrg",
                "registered": "false",
                "username": "rfrfr",
                "timezone": "America/New_York",
                "firstname": "Mrfrfronika ",
                "domainid": "3434444444444444444",
                "type": "0",
                "userid": "4444444444444444444444444444444441",
                "sessionkey": "ewrffffffffffffffffffffff",
                "timezoneoffset": "-4.0",
                "account": "dddd"
              }
            }
        http_version:
      recorded_at: Mon, 24 Sep 2012 10:38:01 GMT
    recorded_with: VCR 2.2.5

这是我处理文件的方式：

thing = YAML.load_file('login_as_user.yml')
http = thing['http_interactions']
alldoc = http[0]
response = alldoc['response']
body = response['body']
bodystring = body['string']

字符串是body键的值，如果我在正文中打印它，它将返回以下内容：

puts body

身体：

{"encoding"=>"ASCII-8BIT", "string"=>"{n  "loginresponse": {n    "timeout": "43200",n    "lastname": "sdsd",n    "registered": "false",n    "username": "sdsdsd",n    "timezone": "America\/New_York",n    "firstname": "sdasdas ",n    "domainid": "ssssssssssss",n    "type": "0",n    "userid": "ssssssssssss1",n    "sessionkey": "sssssssssss",n    "timezoneoffset": "-4.0",n    "account": "sadsadsa"n  }n}n"}

但是如果我像这样检查这个字符串的值：

puts bodystring

它的格式会很好：

{
  "loginresponse": {
  "timeout": "43200",
  "lastname": "wwd",
  "registered": "false",
  "username": "dddd",
  "timezone": "America/New_York",
  "firstname": "dddd ",
  "domainid": "dddfdfdf",
  "type": "0",
  "userid": "dfsdfdsf",
  "sessionkey": "dsfdsfdsf",
  "timezoneoffset": "-4.0",
  "account": "dsfdsfdsfd"
 }
}

所以问题出在转义符号上，当我打开文件并再次写入时，在处理数据后，它的格式错误。

如果有人能帮助我，我将不胜感激。

正文只是一个字符串，但该字符串是哈希的 JSON 编码。 要将 JSON 编码转换为 Ruby 哈希，请使用 json gem：

require 'json'
body_hash = JSON.parse(bodystring)

如果你在 Rails 中，你可能已经加载了 json gem，不需要require。
