这不是像sugget ABDEL-RHMAN那样的中间件问题。如果您没有身份验证，则不会出现404错误，而是401错误
您确定您的laravel应用程序正在8000端口上侦听吗？
如何启动应用程序？您没有从tabRow（）返回任何内容
在DisplayProduct.js中，修改以下内容：
tabRow（）{
if（this.state.products instanceof数组）{
返回this.state.products.map（函数（对象，i）{
回来
})
}
}
将资源
移到中间仓库之外你是上帝的帮助！这解决了404错误。你知道如何处理spread.js:25帖子吗http://localhost:8000/api/products 500（内部服务器错误）
所以在将resurce放置在middlware 404之外的错误消失后，put产品仍然没有显示在页面上？我真的很感激任何帮助，因为我对这种东西还很陌生。非常感谢您没有实现tabrow函数，请尝试返回this.state.products.map（函数（product，i）{return（{product.id}{product.title}）}）
是的，但我没有发布它。请看一看有问题的更新，非常感谢，我真的很感谢您将资源放在middlware之外，我有错误spread.js:25帖子http://localhost:8000/api/products 500（内部服务器错误）spread.js:25未捕获（承诺中）错误：请求失败，状态代码为500，位于e.exports（spread.js:25）在e.exports（spread.js:25）在XMLHttpRequest.l.onreadystatechange（spread.js:25）
