AJAX成功函数未被调用

Question

我试图从AJAX调用获取成功函数到fire.我知道它正常工作,因为我正在使用自己的API,我可以看到它正确地访问了URL并且服务器正在输出HTTP 200.

我认为这是因为服务器正在输出json,所以我试图在AJAX调用中考虑到这一点,但仍然成功函数不起作用.这是我的代码

阿贾克斯

$.ajax('http://localhost:3000/api/users/show/:id', {
  type: 'GET',
  dataType: 'json',
  contentType: "application/json",
  data: {
    id: 1
  },
  success: function(response) {
    return alert("Hey");
  }
});

api方法

class UsersController < ApplicationController
    respond_to :json

    def show
        respond_with User.find(params[:id])
    end

end

服务器日志

Answer 1

这也发生在我身上很长一段时间,我通过将dataType更改为文本并通过eval手动将其转换为json对象来解决这个问题.

$.ajax('http://localhost:3000/api/users/show/:id', {
  type: 'GET',
  dataType: 'text',
  contentType: "application/json",
  data: {
    id: 1
  },
  success: function(response) {
    response = eval(response);
    return alert("Hey");
  }
});

愿这对你有用.

Answer 2

我会添加一个完整的函数并检查文本状态.这应该提供解决问题所需的信息.

complete: function(response, textStatus) {
    return alert("Hey: " + textStatus);
  }
