使用Ajax在Laravel中找不到我的路线中的错误 [英] Can't find the error in my route in Laravel with Ajax
问题描述
我正在使用Laravel 5.6，但出现错误:
I'm using Laravel 5.6, and I have an error :
哎呀，看起来好像出了点问题. (1/1) MethodNotAllowedHttpException
Whoops, looks like something went wrong. (1/1) MethodNotAllowedHttpException
以下是我的观点(leads/show.blade.php):
and the following is my view (leads/show.blade.php):
<form method="post" id="student_form">
{{csrf_field()}}
<span id="form_output"></span>
<div class="form-group">
<label>Choose Group for Your Lead</label>
<select name="group_id" id="group_id" class="form-control">
@foreach($groups as $group)
<option value="{{$group->id}}"> {{$group->name}}</option>
@endforeach
</select>
<input type="hidden" name="customer_id" id="customer_id" value="{{$lead->id}}">
</div>
<div class="modal-footer">
<input type="hidden" name="student_id" id="student_id" value="" />
<input type="hidden" name="button_action" id="button_action" value="insert" />
<input type="submit" name="submit" id="action" value="Add" class="btn btn-info" />
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</form>
- Ajax请求和响应:
<script type="text/javascript">
$(document).ready(function() {
$('#student_form').on('submit', function(event){
event.preventDefault();
var form_data = $(this).serialize();
$.ajax({
url:"{{ route('leads.savegroup') }}",
method:"POST",
data:form_data,
dataType:"json",
success:function(data)
{
if(data.error.length > 0)
{
var error_html = '';
for(var count = 0; count < data.error.length; count++)
{
error_html += '<div class="alert alert-danger">'+data.error[count]+'</div>';
}
$('#form_output').html(error_html);
}
else
{
$('#form_output').html(data.success);
$('#student_form')[0].reset();
$('#action').val('Add');
$('.modal-title').text('Add Data');
$('#button_action').val('insert');
}
}
})
});
});
</script>
，路线是:
Route::post('leads/savegroup', 'LeadsController@savegroup')->name('leads.savegroup');
请帮助我找到错误.

实际上，我也解决了我的问题，问题也出在路线上.
Actually I solved my problem, where the problem was in the route as well.
但是，让我从头开始，我遇到了什么错误阶段以及如何解决它:
But let me start from the beginning, what error stages I faced and how to solve it:
首先:我尝试删除Ajax，并在确保表单正常运行后使用action ="..."正常运行该表单，因此我进入下一阶段来检查Ajax.
first: I tried to remove Ajax, and run the form as normal with action="...", once I ensure that the form working well, so I move to next stage, to check Ajax.
第二:当我开始检查Ajax时，我发现Ajax运行良好，但是出现了问题，但错误仍然显示:
Second: When I start to check Ajax, I found that Ajax is working well, but the problem, but the error still shown:
无法加载资源:服务器响应状态为500 (内部服务器错误)
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
因此，我在应用程序中打开"laravel.log"，并检查了应用程序中的最新错误，发现错误可能来自DB(SQL)或路由.因此，我开始检查控制器，并确保路由中也没有任何错误，因为我之前在其他页面中已经使用过它，并且效果很好.
So I open "laravel.log" in my application, and I checked the latest errors I have in my application, I found that the error maybe came from DB (SQL) or from the route as well. So I moved to check the controller, and I ensure that there is no any error in route as well, because I already use it before in other pages and it works very well.
因此，我最后一次检查路线的机会是，问题也应该出在路线上.我还检查了我的路线，并在更改路线名称等之后很多时间.我注意到我分为两组:
So the last chance for me to check the route, and the problem should be in route as well. I checked my route as well, and after many time on changing the routes names and etc. I noticed that I make it in 2 groups:
第一组:
Route::group(['prefix' => 'leads'], function () {
Route::get('/getdata', 'Controller@getdata')->name('leads.getdata');
}
和第二个不带组的人，如下所示:
and the second one without group, as following:
Route::get('leads/getdata', 'Controller@getdata')->name('leads.getdata');
这也是我的问题.一旦我将路线从小组的外部移动到小组内部>，它就运作良好，问题也得到解决.
So this is my problem as well. Once I moved the route from outside to inside the group > It working well and the problem solved as well.
因此，归根结底，路线中的问题也是如此.
So at the end of the day, the problem in route as well.
