要获取某个字段的值，你可以使用JSON解析方法。在这个例子中，你可以使用以下步骤获取"applyUserId"字段的值：

1. 首先，将JSON字符串解析成一个对象或字典。具体的方法可能会因你使用的编程语言而有所不同。在大多数编程语言中，你可以使用内置的JSON解析函数或库来完成这个步骤。

2. 一旦你将JSON解析为对象或字典，你可以通过指定字段名来访问该字段的值。在这个例子中，你可以使用"applyUserId"来获取"applyUserId"字段的值。

以下是一个示例代码片段，使用Python语言来解析JSON并获取"applyUserId"字段的值：

import json

json_data = '''
{
  "comment": "同意",
  "pass": "true",
  "formData": {
    "faultEscalateTime": "2023-07-12T15:03:55.000+0800",
    "reviewedTime": "",
    "remark": "",
    "updateTime": "2023-07-12T15:04:04.000+0800",
    "delFlag": "0",
    "reviewedBy": "",
    "faultCause": "苏打水",
    "busTaskId": "WX_20230712",
    "applyUserId": "余征",
    "maintenanceStatus": "是的是的343434",
    "symptoms": "是的是的",
    "applyUserName": "余征",
    "createBy": "",
    "instanceId": "17502",
    "createTime": "2023-07-12T15:03:55.000+0800",
    "updateBy": "余征",
    "processKey": "maintenance",
    "id": 35,
    "applyTime": "2023-07-12T15:04:04.000+0800",
    "assignTime": "2023-07-12T15:03:55.000+0800"
  }
}
'''

# 解析JSON
data = json.loads(json_data)

# 获取"applyUserId"字段的值
apply_user_id = data["formData"]["applyUserId"]

print(apply_user_id)

运行以上代码，你将会得到输出：

余征

这样，你就成功获取到了"applyUserId"字段的值。根据你使用的编程语言和具体的JSON解析方法，代码细节可能会有所不同，但基本思路是相似的。
