Javascript Nodejs请求-无法读取属性'；forEach&x27；未定义的

我在学习一个无头Drupal教程，但我的经验是使用Drupal端而不是节点端，所以现在有些东西坏了，我不知道如何修复

启动应用程序时，我收到一个错误：

/Library/WebServer/Documents/uno-fe/hellotest.js:23
blogsdata_all.blogs.forEach(function(item){
                   ^

TypeError: Cannot read property 'forEach' of undefined
    at Request._callback (/Library/WebServer/Documents/uno-fe/hellotest.js:23:24)
    at Request.self.callback (/Library/WebServer/Documents/uno-fe/node_modules/request/request.js:200:22)
    at emitTwo (events.js:87:13)

我假设这与节点请求没有从“源”站点正确获取json有关，这就是blogs var为空的原因。不知道出了什么问题-非常感谢任何帮助

您应该对响应主体进行console.log记录，以查看其外观。是空的吗

据我所知，url是正确的，响应是：

[{"title":"second post","created":"2016-06-30T15:49:17+08:00","field_blog_image":"  \n\n","path":"\/node\/2","created_1":"30 2016 Jun","body_1":"some content","body":"some content","uid":"","user_picture":""},{"title":"first post","created":"2016-06-28T21:56:52+08:00","field_blog_image":"  \n\n","path":"\/node\/1","created_1":"28 2016 Jun","body_1":"woot","body":"woot","uid":"","user_picture":""}]

如果是这样，你应该这样做：

blogsdata_all.forEach(function(item){
    blogs.push(item);
});

因为响应主体是一个对象数组。如果响应如下所示，则您尝试循环的方式是正确的：

{"blogs":[{"title":"second post","created":"2016-06-30T15:49:17+08:00","field_blog_image":"  \n\n","path":"\/node\/2","created_1":"30 2016 Jun","body_1":"some content","body":"some content","uid":"","user_picture":""},{"title":"first post","created":"2016-06-28T21:56:52+08:00","field_blog_image":"  \n\n","path":"\/node\/1","created_1":"28 2016 Jun","body_1":"woot","body":"woot","uid":"","user_picture":""}] }

此外，您不必通过循环将博客文章推回到一个新的数组中，您可以直接使用：

app.locals.blogsdata = blogsdata_all;

检查

错误

和响应代码。当然，获取dataThnx时存在问题。这对我很有帮助，对于我的项目，我用

年龄组来解决这个问题：any=[]
app.locals.blogsdata = blogsdata_all;
