Question

我将变量设置为等于JSON文本，如下所示：

var httpResponseBackup = {"findItemsByKeywordsResponse":[{"searchResult":["nada"]}]}

然而，当我运行我的云代码时，它给了我这个错误：

Uncaught SyntaxError: Unexpected token o in <unknown file>:1

基于我通过Google搜索此错误找到的内容，它与以下代码行有关：

var ebayResponse = JSON.parse(httpResponseBackup);

我是否错误地格式化httpResponseBackup中的JSON文字？

Answer 1

JSON.parse需要一个字符串，字符串化JSON。您传递的内容已经是JSON对象。因此，您可以设置对该对象的响应：

var ebayResponse = httpResponseBackup;

或者，您可以将httpReponseBackup设置为字符串值：

var httpResponseBackup = '{"findItemsByKeywordsResponse":[{"searchResult":["nada"]}]}'

鉴于：

<div id="myCarousel" class="carousel slide img-rounded" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
  <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
  <li data-target="#myCarousel" data-slide-to="1"></li>
  <li data-target="#myCarousel" data-slide-to="2"></li>
  <li data-target="#myCarousel" data-slide-to="3"></li>
  <li data-target="#myCarousel" data-slide-to="4"></li>
</ol>

<!-- Wrapper for slides -->
<div class="carousel-inner" role="listbox">
<div class="item active">
  <%= image_tag("nicholson2.jpg", alt:"nicholson", class: "img-rounded") %>
</div>

<div class="item">
  <%= image_tag("marilyn2.jpg", alt:"marilyn", class: "img-rounded") %>
</div>

<div class="item">
  <%= image_tag("pacino2.jpg", alt:"pacino", class: "img-rounded") %>
</div>

<div class="item">
  <%= image_tag("lily.jpg", alt:"lily", class: "img-rounded") %>
</div>

<div class="item">
  <%= image_tag("deniro2.jpg", alt:"deniro", class: "img-rounded") %>
</div>
</div>

<!-- Left and right controls -->
<a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>

，然后

var httpResponseBackup = {"findItemsByKeywordsResponse":[{"searchResult":["nada"]}]}; var httpResponseBackupString = '{"findItemsByKeywordsResponse":[{"searchResult":["nada"]}]}';

并

JSON.stringify(httpResponseBackup) == httpResponseBackupString将返回一个与JSON.parse(httpResponseBackupString)具有相同结构的新对象。
