無法從CakePHP 3的AJAX請求中獲取數據

Question

Javascript正在工作，當我訪問histories/history時。 alert顯示'succes'。如果可以，請你幫助我。

function sendFPost(){ 
    var hello = "Hello World"; 
    $.ajax({ 
     type: 'POST', 
     url: '/untitled/histories/history', 
     data: hello, 
     dataType: 'html', 
     success: function() { 
      alert('success'); 
     }, 
     error: function() { 
      alert('error'); 
     } 
    }); 
} 

sendFPost(); 

public function history() 
{ 
    print_r($this->request->data); 
}

我想使用JSON請求建議：

Ajax請求：

function sendFPost(){ 
var name = 'abc'; 
var email = 'abc@gmail.com'; 
var phone = 1234; 
$.ajax({ 
    type: 'POST', 
    url: '/untitled/histories/history.json', // json request 
    data: "name="+name+"&email="+email+"&phone="+phone, 
    dataType: 'html', 
    success: function (response) { 
     console.log(response); 
    }, 
    error: function() { 
     alert('error'); 
    } 
}); 
} 
sendFPost(); 

在控制器：

public function history() 
{ 
    if($this->request->is('post')) { 
    $data = $this->request->data; 
    $this->set([ 
     'data'=>$data, 
     '_serialize'=>'data' // this will appear within success of ajax 
    ]); 
    } 
} 

如果您以前沒有做過，則可能需要在路由中啓用json擴展。
