Question

解决了！谢谢大家！结果我应该直接使用parseString的结果。那个，JSON对象在数组中。

var content = result.ItemLookupResponse.Items[0].Item[0].ASIN;

^这正是我所需要的。

我在解析JSON对象时遇到了麻烦，以便将某些值发送到视图，以便前端用户可以看到JSON中的内容。我尝试过使用JSON.stringify（）然后使用JSON.parse（）。最终归还了这个：

{ '$': { xmlns: 'http://webservices.amazon.com/AWSECommerceService/2011-08-01' },
  OperationRequest: 
   [ { RequestId: [Object],
       Arguments: [Object],
       RequestProcessingTime: [Object] } ],
  Items: [ { Request: [Object], Item: [Object] } ] }

以下是原始JSON：http://pastebin.com/XDK9Y0gy

我需要获得的是ASIN值，可以在Items-＆gt; Item-＆gt; ASIN找到。

parseString(xml, function (err, result) {
                //parse the JSON here then res.send that (or render it with the json. do rest from view)
                //data = JSON.stringify(result);
                //var jsonObj = JSON.parse(data);
                //console.log(jsonObj);
                //var ITEMASIN = jsonDoc['Items']['Item']['ASIN'];
                var json = JSON.stringify(result);

                //var rawData = '[{"item1":"tag1","a1":"b1"},{"item2":"tag2","a2":"b2"}]';
                var parsed = JSON.parse(json);
                var content = parsed.ItemLookupResponse.Items[0].Item.ASIN;
                //console.log(parsed.ItemLookupResponse.Items.Item[0].ASIN); // logs "b1"

                res.render('artreview', {content: content});
            });

^这会返回一个未定义的任何帮助表示赞赏

Answer 1

应该是：result.ItemLookupResponse.Items[0].Item[0].ASIN[0]

由于数据已经是JavaScript对象，因此您无需为JSON.stringify和JSON.parse

而烦恼

Answer 2

如果您使用原始JSON

，则为object.ItemLookupResponse.Items[0].Item[0].ASIN[0]

http://jsfiddle.net/fkLtkotm/

Answer 3

如果这确实是JSON，那么大多数值实际上是数组。因此，您需要像object.ItemLookupResponse.Items[0].Item[0].ASIN[0]一样访问它们。

Answer 4

您需要使用ItemLookupResponse.Items[0].Item[0].ASIN[0];。

以下是一个实时演示，可以检索并显示第一个项目的ASIN。

Answer 5

假设您的json已解析为 myJson 变量：

myJson.ItemLookupResponse.Items[0].Item[0].ASIN

将为您提供ASIN值

无法解析要发送到视图的JSON值
