无法解析JavaScript中json对象内的值

Question

我试图解析一个驻留在json对象中的值。 以下是我的API调用的响应。

var responseData = {
  "statusCode": 200,
  "body": "{\"Errors\":\"\",\"Message\":null,\"OrgID\":0,\"Output\":\"{\\\"AllUserDetails\\\":{\\\"UserDetails \\\":[{\\\"UserID\\\":1012,\\\"UserName\\\":\\\"Arul, Velu\\\",\\\"EmpID\\\":null,\\\"Role\\\":\\\"SA\\\",\\\"RoleName\\\":\\\"Super Admin\\\",\\\"EmailID\\\":\\\"Arulvelu@gmail.com\\\",\\\"NT_UID\\\":\\\"ICS\\\\\\\\RNair\\\",\\\"Frm_UID\\\":\\\"Arulvelu@gmail.com\\\",\\\"Frm_PWD\\\":\\\"3ZD1KS+4gEL5RKsjlC5k0MIfaiV8k\\/ixZRS6NpNyu0g=\\\",\\\"Org_Id\\\":1,\\\"Instance_Model\\\":\\\"Dependent\\\",\\\"Org_Name\\\":\\\"India\\\",\\\"AccessCreate_Portfolio\\\":false,\\\"AccessEdit_Portfolio\\\":false,\\\"Customer\\\":2592,\\\"Customer_Name\\\":\\\"ICS\\\",\\\"Location\\\":null,\\\"Location_Name\\\":\\\"\\\",\\\"Userlevel\\\":2544,\\\"User_Level\\\":\\\"Analyst\\\",\\\"Country\\\":null,\\\"Designation\\\":\\\"Consultant\\\",\\\"ContactNo\\\":\\\"2133232123\\\",\\\"MobileNo\\\":null,\\\"JoinDate\\\":\\\"2016-01-06 00:00:00\\\",\\\"Access_ServerMon\\\":false,\\\"Access_IncidentMgmt\\\":true,\\\"Access_CMCMDB\\\":true,\\\"Access_CMDB\\\":true,\\\"Access_RM\\\":true,\\\"Access_KnowledgeMgmt\\\":true,\\\"Access_PortfolioMgmt\\\":true,\\\"Access_ServiceRequest\\\":true,\\\"Access_ServiceCatalog\\\":true,\\\"Access_NetworkMon\\\":false,\\\"Access_AssetMgmt\\\":true,\\\"Access_ProblemMgmt\\\":true,\\\"Access_ProjectMgmt\\\":true,\\\"Access_SkillPack\\\":true,\\\"Access_FinMgmt\\\":false,\\\"Access_SLA\\\":true,\\\"SLAMgr\\\":false,\\\"AccessType_ServerMon\\\":\\\"No Access\\\",\\\"AccessType_IncidentMgmt\\\":\\\"No Access\\\",\\\"AccessType_CMCMDB\\\":\\\"No Access\\\",\\\"AccessType_CMDB\\\":\\\"\\\",\\\"AccessType_RM\\\":\\\"\\\",\\\"AccessType_KnowledgeMgmt\\\":\\\"\\\",\\\"AccessType_PortfolioMgmt\\\":\\\"\\\",\\\"AccessType_ServiceRequest\\\":\\\"\\\",\\\"AccessType_ServiceCatalog\\\":\\\"\\\",\\\"AccessType_NetworkMon\\\":\\\"No Access\\\",\\\"AccessType_AssetMgmt\\\":\\\"No Access\\\",\\\"AccessType_ProblemMgmt\\\":\\\"No Access\\\",\\\"AccessType_ProjectMgmt\\\":\\\"No Access\\\",\\\"AccessType_SkillPack\\\":\\\"No Access\\\",\\\"AccessType_WorkOrder\\\":\\\"No Access\\\",\\\"AccessType_FinMgmt\\\":\\\"No Access\\\",\\\"AccessType_SLA\\\":\\\"\\\",\\\"Address\\\":\\\"2901 Butterfield Rd\\\\n2nd Flooor\\\",\\\"UserRemarks\\\":\\\"\\\",\\\"State\\\":\\\"\\\",\\\"City\\\":\\\"\\\",\\\"Pin\\\":\\\"\\\",\\\"Active\\\":true,\\\"UT_ID\\\":90,\\\"AccessType_SkillPack1\\\":\\\"No Access\\\",\\\"Access_EProc\\\":true,\\\"AccessType_Eproc\\\":\\\"General Access\\\",\\\"Entity_Access\\\":\\\"\\\",\\\"TimeZone\\\":\\\"(UTC - 06:00) CST - Central Standard Time\\\",\\\"GMT_TimeDiff\\\":-300,\\\"Access_EventMgmt\\\":false,\\\"AccessType_EventMgmt\\\":\\\"No Access\\\",\\\"Keyword_Access\\\":\\\"\\\",\\\"ManagerName\\\":\\\"Arulvelu\\\",\\\"ProjMgmt_InstanceAccess\\\":\\\"\\\",\\\"Manager_UserID\\\":null,\\\"IM_ExtendedRole\\\":\\\"RPT\\\",\\\"AM_ExtendedRole\\\":\\\"RPT\\\",\\\"CustomerMasterID\\\":11,\\\"OrgLogoActive\\\":null,\\\"CustomerLogoActive\\\":null,\\\"AM_EditTemplateID\\\":0,\\\"DesignationID\\\":1381,\\\"PT_userAccessLevel\\\":\\\"Analyst\\\",\\\"PT_workgroupId\\\":0,\\\"PT_CostcentreID\\\":0,\\\"Alternative_EmailID\\\":\\\" , , ,\\\",\\\"ManagerEmailID\\\":null,\\\"ManagerEmployeeID\\\":null}]}}\",\"OutputObject\":null,\"TokenID\":null}",
  "headers": {
    "cache-control": "private",
    "content-type": "application/json; charset=utf-8",
    "server": "Microsoft-IIS/8.5",
    "set-cookie": [
      "ASP.NET_SessionId=2ncl0ezht5; path=/; HttpOnly"
    ],
    "x-aspnet-version": "4.0.30319",
    "x-powered-by": "ASP.NET",
    "date": "Sat, 13 Oct 2018 20:12:39 GMT",
    "connection": "close",
    "content-length": "3314"
  }
}

我可以使用responseData.body获得主体值。 但是我需要检索body.Output.AllUserDetails.UserDetails [0].UserID内部的值。它抛出错误，指出AllUserDetailsis未定义。 谁能帮我。

Answer 1

尝试这个：

JSON.parse(JSON.parse(responseData.body).Output).AllUserDetails['UserDetails '][0].UserID

请注意， UserDetails在api响应中有一个额外的空间，因此您不能使用点符号来访问它。

Answer 2

简单的答案：

JSON.parse(JSON.parse(responseData.body).Output)

然后获取所需的任何属性。

长答案：

对象内部的json是字符串而不是对象。

Answer 3

您必须多次执行JSON.parse然后才能访问用户详细信息

 var responseData = { "statusCode": 200, "body": "{\\"Errors\\":\\"\\",\\"Message\\":null,\\"OrgID\\":0,\\"Output\\":\\"{\\\\\\"AllUserDetails\\\\\\":{\\\\\\"UserDetails \\\\\\":[{\\\\\\"UserID\\\\\\":1012,\\\\\\"UserName\\\\\\":\\\\\\"Arul, Velu\\\\\\",\\\\\\"EmpID\\\\\\":null,\\\\\\"Role\\\\\\":\\\\\\"SA\\\\\\",\\\\\\"RoleName\\\\\\":\\\\\\"Super Admin\\\\\\",\\\\\\"EmailID\\\\\\":\\\\\\"Arulvelu@gmail.com\\\\\\",\\\\\\"NT_UID\\\\\\":\\\\\\"ICS\\\\\\\\\\\\\\\\RNair\\\\\\",\\\\\\"Frm_UID\\\\\\":\\\\\\"Arulvelu@gmail.com\\\\\\",\\\\\\"Frm_PWD\\\\\\":\\\\\\"3ZD1KS+4gEL5RKsjlC5k0MIfaiV8k\\\\/ixZRS6NpNyu0g=\\\\\\",\\\\\\"Org_Id\\\\\\":1,\\\\\\"Instance_Model\\\\\\":\\\\\\"Dependent\\\\\\",\\\\\\"Org_Name\\\\\\":\\\\\\"India\\\\\\",\\\\\\"AccessCreate_Portfolio\\\\\\":false,\\\\\\"AccessEdit_Portfolio\\\\\\":false,\\\\\\"Customer\\\\\\":2592,\\\\\\"Customer_Name\\\\\\":\\\\\\"ICS\\\\\\",\\\\\\"Location\\\\\\":null,\\\\\\"Location_Name\\\\\\":\\\\\\"\\\\\\",\\\\\\"Userlevel\\\\\\":2544,\\\\\\"User_Level\\\\\\":\\\\\\"Analyst\\\\\\",\\\\\\"Country\\\\\\":null,\\\\\\"Designation\\\\\\":\\\\\\"Consultant\\\\\\",\\\\\\"ContactNo\\\\\\":\\\\\\"2133232123\\\\\\",\\\\\\"MobileNo\\\\\\":null,\\\\\\"JoinDate\\\\\\":\\\\\\"2016-01-06 00:00:00\\\\\\",\\\\\\"Access_ServerMon\\\\\\":false,\\\\\\"Access_IncidentMgmt\\\\\\":true,\\\\\\"Access_CMCMDB\\\\\\":true,\\\\\\"Access_CMDB\\\\\\":true,\\\\\\"Access_RM\\\\\\":true,\\\\\\"Access_KnowledgeMgmt\\\\\\":true,\\\\\\"Access_PortfolioMgmt\\\\\\":true,\\\\\\"Access_ServiceRequest\\\\\\":true,\\\\\\"Access_ServiceCatalog\\\\\\":true,\\\\\\"Access_NetworkMon\\\\\\":false,\\\\\\"Access_AssetMgmt\\\\\\":true,\\\\\\"Access_ProblemMgmt\\\\\\":true,\\\\\\"Access_ProjectMgmt\\\\\\":true,\\\\\\"Access_SkillPack\\\\\\":true,\\\\\\"Access_FinMgmt\\\\\\":false,\\\\\\"Access_SLA\\\\\\":true,\\\\\\"SLAMgr\\\\\\":false,\\\\\\"AccessType_ServerMon\\\\\\":\\\\\\"No Access\\\\\\",\\\\\\"AccessType_IncidentMgmt\\\\\\":\\\\\\"No Access\\\\\\",\\\\\\"AccessType_CMCMDB\\\\\\":\\\\\\"No Access\\\\\\",\\\\\\"AccessType_CMDB\\\\\\":\\\\\\"\\\\\\",\\\\\\"AccessType_RM\\\\\\":\\\\\\"\\\\\\",\\\\\\"AccessType_KnowledgeMgmt\\\\\\":\\\\\\"\\\\\\",\\\\\\"AccessType_PortfolioMgmt\\\\\\":\\\\\\"\\\\\\",\\\\\\"AccessType_ServiceRequest\\\\\\":\\\\\\"\\\\\\",\\\\\\"AccessType_ServiceCatalog\\\\\\":\\\\\\"\\\\\\",\\\\\\"AccessType_NetworkMon\\\\\\":\\\\\\"No Access\\\\\\",\\\\\\"AccessType_AssetMgmt\\\\\\":\\\\\\"No Access\\\\\\",\\\\\\"AccessType_ProblemMgmt\\\\\\":\\\\\\"No Access\\\\\\",\\\\\\"AccessType_ProjectMgmt\\\\\\":\\\\\\"No Access\\\\\\",\\\\\\"AccessType_SkillPack\\\\\\":\\\\\\"No Access\\\\\\",\\\\\\"AccessType_WorkOrder\\\\\\":\\\\\\"No Access\\\\\\",\\\\\\"AccessType_FinMgmt\\\\\\":\\\\\\"No Access\\\\\\",\\\\\\"AccessType_SLA\\\\\\":\\\\\\"\\\\\\",\\\\\\"Address\\\\\\":\\\\\\"2901 Butterfield Rd\\\\\\\\n2nd Flooor\\\\\\",\\\\\\"UserRemarks\\\\\\":\\\\\\"\\\\\\",\\\\\\"State\\\\\\":\\\\\\"\\\\\\",\\\\\\"City\\\\\\":\\\\\\"\\\\\\",\\\\\\"Pin\\\\\\":\\\\\\"\\\\\\",\\\\\\"Active\\\\\\":true,\\\\\\"UT_ID\\\\\\":90,\\\\\\"AccessType_SkillPack1\\\\\\":\\\\\\"No Access\\\\\\",\\\\\\"Access_EProc\\\\\\":true,\\\\\\"AccessType_Eproc\\\\\\":\\\\\\"General Access\\\\\\",\\\\\\"Entity_Access\\\\\\":\\\\\\"\\\\\\",\\\\\\"TimeZone\\\\\\":\\\\\\"(UTC - 06:00) CST - Central Standard Time\\\\\\",\\\\\\"GMT_TimeDiff\\\\\\":-300,\\\\\\"Access_EventMgmt\\\\\\":false,\\\\\\"AccessType_EventMgmt\\\\\\":\\\\\\"No Access\\\\\\",\\\\\\"Keyword_Access\\\\\\":\\\\\\"\\\\\\",\\\\\\"ManagerName\\\\\\":\\\\\\"Arulvelu\\\\\\",\\\\\\"ProjMgmt_InstanceAccess\\\\\\":\\\\\\"\\\\\\",\\\\\\"Manager_UserID\\\\\\":null,\\\\\\"IM_ExtendedRole\\\\\\":\\\\\\"RPT\\\\\\",\\\\\\"AM_ExtendedRole\\\\\\":\\\\\\"RPT\\\\\\",\\\\\\"CustomerMasterID\\\\\\":11,\\\\\\"OrgLogoActive\\\\\\":null,\\\\\\"CustomerLogoActive\\\\\\":null,\\\\\\"AM_EditTemplateID\\\\\\":0,\\\\\\"DesignationID\\\\\\":1381,\\\\\\"PT_userAccessLevel\\\\\\":\\\\\\"Analyst\\\\\\",\\\\\\"PT_workgroupId\\\\\\":0,\\\\\\"PT_CostcentreID\\\\\\":0,\\\\\\"Alternative_EmailID\\\\\\":\\\\\\" , , ,\\\\\\",\\\\\\"ManagerEmailID\\\\\\":null,\\\\\\"ManagerEmployeeID\\\\\\":null}]}}\\",\\"OutputObject\\":null,\\"TokenID\\":null}", "headers": { "cache-control": "private", "content-type": "application/json; charset=utf-8", "server": "Microsoft-IIS/8.5", "set-cookie": [ "ASP.NET_SessionId=2ncl0ezht5; path=/; HttpOnly" ], "x-aspnet-version": "4.0.30319", "x-powered-by": "ASP.NET", "date": "Sat, 13 Oct 2018 20:12:39 GMT", "connection": "close", "content-length": "3314" } } var responseJSON = JSON.parse(JSON.stringify(responseData)); var responseJSONBody = JSON.parse(responseJSON.body) var responseJSONBodyOutput = JSON.parse(responseJSONBody.Output) console.log(responseJSONBodyOutput); 

Answer 4

尝试这个 -

body.Output.AllUserDetails['UserDetails '][0].UserID
