Question

我从服务器收到以下响应，如下所示

{
  "statusCode": 200,
  "body": "{\"Errors\":\"\",\"Message\":\"\",\"Output\":\"\",\"TokenID\":\"F106457749C\",\"OrgID\":0,\"OutputObject\":{\"Details\":{\"CatalogDetail\":[{\"CatalogID\":74,\"CategoryID\":22,\"ShortCatalogName\":\"Email Forwarding\",\"CatalogName\":\"Email Forwarding\",\"Description\":\"Use this catalog for email forwarding \",\"IsVendor\":false,\"IsPackage\":false,\"AncestorParent_CategoryID\":58,\"IsEntitled\":0,\"CategoryName\":\"Email\",\"ServiceCatalogBGColor\":\"\"}],\"BaseUrl\":\"https://serviceimg-attachments\"}}}",
  "headers": {
    "cache-control": "private",
    "content-type": "application/octet-stream",
    "server": "Microsoft-IIS/8.5",
    "set-cookie": [
      "ASP.NET_SessionId=m0jbtyi12mzefkkyh3xd4i0m; path=/; HttpOnly",
      ".ASPXAUTH=41C6BC3E87DBF106457749C; path=/"
    ],
    "x-aspnet-version": "4.0.30319",
    "x-powered-by": "ASP.NET",
    "date": "Mon, 15 Oct 2018 17:51:09 GMT",
    "connection": "close",
    "content-length": "779"
  }
}

我想解析正文reponse.body这是一个字符串。进行解析的原因是获取数组response.body.OutputObject.Details.CatalogDetail。但是当我这样做时，我得到Details as undefined。谁能帮助我获得CatalogDetail数组。

谢谢阿鲁尔

Answer 1

尝试这样：

var myObject = JSON.parse("my json string");

Answer 2

您必须先解析json，然后才能访问obj，JSON.parse将解析json字符串。

var json = '{"result":true, "count":42}';
obj = JSON.parse(json);

Answer 3

这是因为主体的值是字符串格式，并且如果要以json格式访问它，则需要首先对其进行解析，请查看下面的代码片段以获取更多信息。

var response = {
  "statusCode": 200,
  "body": "{\"Errors\":\"\",\"Message\":\"\",\"Output\":\"\",\"TokenID\":\"F106457749C\",\"OrgID\":0,\"OutputObject\":{\"Details\":{\"CatalogDetail\":[{\"CatalogID\":74,\"CategoryID\":22,\"ShortCatalogName\":\"Email Forwarding\",\"CatalogName\":\"Email Forwarding\",\"Description\":\"Use this catalog for email forwarding \",\"IsVendor\":false,\"IsPackage\":false,\"AncestorParent_CategoryID\":58,\"IsEntitled\":0,\"CategoryName\":\"Email\",\"ServiceCatalogBGColor\":\"\"},{\"CatalogID\":75,\"CategoryID\":22,\"ShortCatalogName\":\"Email Forwarding2\",\"CatalogName\":\"Email Forwarding2\",\"Description\":\"Use this catalog for email forwarding \",\"IsVendor\":false,\"IsPackage\":false,\"AncestorParent_CategoryID\":58,\"IsEntitled\":0,\"CategoryName\":\"Email\",\"ServiceCatalogBGColor\":\"\"}],\"BaseUrl\":\"https://serviceimg-attachments\"}}}",
  "headers": {
    "cache-control": "private",
    "content-type": "application/octet-stream",
    "server": "Microsoft-IIS/8.5",
    "set-cookie": [
      "ASP.NET_SessionId=m0jbtyi12mzefkkyh3xd4i0m; path=/; HttpOnly",
      ".ASPXAUTH=41C6BC3E87DBF106457749C; path=/"
    ],
    "x-aspnet-version": "4.0.30319",
    "x-powered-by": "ASP.NET",
    "date": "Mon, 15 Oct 2018 17:51:09 GMT",
    "connection": "close",
    "content-length": "779"
  }
}
var body = JSON.parse(response.body)
var Catelogs = body.OutputObject.Details.CatalogDetail;
for(var i=0;i<Catelogs.length;i++){
    console.log("CatalogID : " + Catelogs[i].CatalogID)
    console.log("ShortCatalogName : " + Catelogs[i].ShortCatalogName);
}
$.each(Catelogs, function( index, value ) {
  console.log(  "CatalogID : " + value.CatalogID );  
  console.log(  "ShortCatalogName : " + value.ShortCatalogName );
});

您可以使用简单的for循环或$ .each循环遍历数组

Answer 4

我正在按照以下方式进行操作，并且正在工作。我无法解析完整的对象。分别获取身体对象。

var body = JSON.parse(res["body"])

然后按以下方式使用它。

JSON.parse(res["body"]).OutputObject.Details.CatalogDetail

Answer 5

您需要将正文解析为json。可能无论您使用的是哪种框架都有类似response.json()的方法，但是您可以只使用JSON.parse。

response = {
  "statusCode": 200,
  "body": "{\"Errors\":\"\",\"Message\":\"\",\"Output\":\"\",\"TokenID\":\"F106457749C\",\"OrgID\":0,\"OutputObject\":{\"Details\":{\"CatalogDetail\":[{\"CatalogID\":74,\"CategoryID\":22,\"ShortCatalogName\":\"Email Forwarding\",\"CatalogName\":\"Email Forwarding\",\"Description\":\"Use this catalog for email forwarding \",\"IsVendor\":false,\"IsPackage\":false,\"AncestorParent_CategoryID\":58,\"IsEntitled\":0,\"CategoryName\":\"Email\",\"ServiceCatalogBGColor\":\"\"}],\"BaseUrl\":\"https://serviceimg-attachments\"}}}",
  "headers": {
    "cache-control": "private",
    "content-type": "application/octet-stream",
    "server": "Microsoft-IIS/8.5",
    "set-cookie": [
      "ASP.NET_SessionId=m0jbtyi12mzefkkyh3xd4i0m; path=/; HttpOnly",
      ".ASPXAUTH=41C6BC3E87DBF106457749C; path=/"
    ],
    "x-aspnet-version": "4.0.30319",
    "x-powered-by": "ASP.NET",
    "date": "Mon, 15 Oct 2018 17:51:09 GMT",
    "connection": "close",
    "content-length": "779"
  }
}
body = JSON.parse(response.body)
body.OutputObject.Details.CatalogDetail

Answer 6

使用JSON.parse(data.body)将字符串解析为JSON，然后您就可以执行任何操作了，

了解更多JSON.parse

下面是代码段

var data = {
  "statusCode": 200,
  "body": "{\"Errors\":\"\",\"Message\":\"\",\"Output\":\"\",\"TokenID\":\"F106457749C\",\"OrgID\":0,\"OutputObject\":{\"Details\":{\"CatalogDetail\":[{\"CatalogID\":74,\"CategoryID\":22,\"ShortCatalogName\":\"Email Forwarding\",\"CatalogName\":\"Email Forwarding\",\"Description\":\"Use this catalog for email forwarding \",\"IsVendor\":false,\"IsPackage\":false,\"AncestorParent_CategoryID\":58,\"IsEntitled\":0,\"CategoryName\":\"Email\",\"ServiceCatalogBGColor\":\"\"}],\"BaseUrl\":\"https://serviceimg-attachments\"}}}",
  "headers": {
    "cache-control": "private",
    "content-type": "application/octet-stream",
    "server": "Microsoft-IIS/8.5",
    "set-cookie": [
      "ASP.NET_SessionId=m0jbtyi12mzefkkyh3xd4i0m; path=/; HttpOnly",
      ".ASPXAUTH=41C6BC3E87DBF106457749C; path=/"
    ],

    "date": "Mon, 15 Oct 2018 17:51:09 GMT",
    "connection": "close",
    "content-length": "779"
  }
};
var output = JSON.parse(data.body);
console.log(output.OutputObject.Details.CatalogDetail);
