谁能告诉我为什么从硬盘驱动器访问数据时，此代码为什么能在HTML页面中完美地工作，但是当我将其添加到express和node中时，却得到了
SyntaxError：JSON.parse：JSON数据的第1行第1列出现意外字符
具有完美格式的代码。我知道我使用格式化程序对其进行了测试，甚至手动创建了一个json对象。这是代码：

let output = '<h2>Property</h2>';
console.log(data);
data.propertystandings.propertystandingsentry.forEach(function(propertyEntry){
output += `
<ul>
<li>id: ${propertyEntry.property.ID}</li>
<li>city: ${propertyEntry.property.City}</li>
<li>prop name: ${propertyEntry.property.Name}</li>
<li>prop name: ${propertyEntry.rank}</li>
</ul>
`;
});
document.getElementById('output').innerHTML = output;
})
}
</script>
</body>
</html>
</html>
</html>
But then this code in express causes the error- …
