【问题描述】：
我是 Laravel 的新手，并试图通过 ajax 向数据库添加数据，但它抛出此消息：“服务器响应状态为 405（不允许方法）”我为此定义了两条路由用于表单页面
Route::get('/create/{id}', 'Participant\ParticipantProjectDefinitionController@create')->name('participant.project-definition.create');
和其他保存这些数据的方法是这样的：
// To save Project definition Data
Route::get('/store-project-definition-data/{id}', 'Participant\ParticipantProjectDefinitionController@store')->name('participant.project-definition.store');
我使用的 Ajax 代码是这样的：
function storeDefinitionFormData(addUrl, token, baseUrl){
$('#create_project_definition_data').click(function(e){
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
e.preventDefault();
var form_fields = [];
var counter = 0;
$('.form-group').each(function(){
var values = {
'field_name' : $('#field_name_' + counter).val(),
'field_data' : $('#field_data_' + counter).val(),
};
form_fields.push(values);
counter++;
});
$.ajax({
type: 'POST',
dataType: 'JSON',
url: addUrl,
data: {
'_token' : token,
'customer_name' : $('#field_name_0').val(),
'customer_name' : $('#field_data_0').val(),
// 'form_fields' : form_fields
},
success: function(data){
alert('done');
window.location = baseUrl;
},
error: function(data){
alert('fail');
if(data.status == 422){
errors = data.responseJSON.errors; // => colllect all errors from the error bag
var fieldCounter = 0;
$('.help-block').show();
$('.validation').empty(); // => clear all validation
// display the validations
$('.validation').css({
'display' : 'block'
});
// iterate through each errors
$.each(errors, function(key, value){
if(key.includes('form_fields.')){
var field_errors = key.split('.');
var field_error = field_errors[2] + "_" + field_errors[1];
$('#' + field_error + '_error').append("<i class='zmdi zmdi-alert-circle' style='font-size: 15px;'></i> " + value); // => append the error value in the error message
}
$('#' + key + '_help').hide();
$('#' + key + '_error').append("<i class='zmdi zmdi-alert-circle' style='font-size: 15px;'></i> " + value); // => append the error value in the error message
});
}
}
});
});
}
控制器代码
/**
* create project Definition Form
*
*/
public function create(request $request, $id){
$ProjectDefinitionFields = ProjectDefinitionFields::all();
$ProjectDefinitionFieldRow = ProjectDefinitionFields::where('project_definition_id','=', $id)->get();
// dd($ProjectDefinitionFieldRow);
return view('participants.project_definition.create', ['ProjectDefinitionFieldRow' => $ProjectDefinitionFieldRow]);
}
public function store(request $request, $id, User $user, ProjectDefinitionFields $ProjectDefinitionFields){
$project = ProjectDefinitionFields::find('field_id');
$count = ProjectDefinitionFields::where('project_definition_id','=', $id)->count();
$pd_id = ProjectDefinitionFields::where('project_definition_id','=', $id)->get();
for($i=0;$i<$count;$i++){
$data[]= array (
'field_name'=>$request->get('field_name_'.$i),
'field_data'=>$request->get('field_data_'.$i),
'user_id' => Auth::user()->id,
// 'user_id' => $request->user()->id,
'project_definition_id' => $pd_id,
// 'field_id' => $projectDefinitionFields->id,
);
}
$project_data = ProjectDefinitionData::create($data);
if($project_data){
return response()->json($project_data);
}
}
型号
on ProjectDefinition
public function formFields(){
// return $this->hasMany('App\Model\ProjectDefinitionFields');
return $this->belongsTo('App\Model\ProjectDefinitionFields');
}
on projectDefinitionFields
public function projectDefinition(){
return $this->belongsTo('App\Model\ProjectDefinition');
}
这是我的 create.blade.php
<form id="create_project_definition_data_form" enctype="multipart/form-data" >
@csrf
{{ method_field('PUT') }}
<?php $count = 0; ?>
@foreach($ProjectDefinitionFieldRow as $value)
<div class="row">
<div class="form-group col-md-12" id="form-group">
<div class="row">
<label for="definition_data_<?php echo $count; ?>" class="col-sm-2 col-md-2 col-form-label" id="field_name_<?php echo $count; ?>" name="field_name_<?php echo $count; ?>[]" value="{{$value->field_name }}">{{$value->field_name }}</label>
<div class="col-sm-10 col-md-10">
{{-- textbox = 1
textarea = 0 --}}
<<?php if($value->field_type = 1){echo "input";}else{echo "textarea";} ?> class="form-control" name="field_data_<?php echo $count; ?>[]" placeholder="Enter project definition_data" id="field_data_<?php echo $count; ?>" aria-describedby="field_data_help"></<?php if($value->field_type = 1){echo "input";}else{echo "textarea";} ?>>
<small id="field_data_help_<?php echo $count; ?>" class="form-text text-muted help-block">
Optional Field.
</small>
<span id="field_data_error_<?php echo $count; ?>" class="invalid-feedback validation"></span>
</div>
</div>
</div>
</div>
<hr />
<?php $count++; ?>
@endforeach
<div class="text-center">
<button type="submit" class="btn btn-primary" id="create_project_definition_data">Create Project Defination Data</button>
</div>
</form>
@section('scripts')
<script src="{{ asset('js/participants/project-definition.js') }}"></script>
<script>
// on document ready
$(document).ready(function(){
var baseUrl = "{{ url('/') }}";
var indexPdUrl = "{{ route('participant.projectDefinition') }}";
var token = "{{ csrf_token() }}";
{{-- // var addUrl = "{{ route('participant.project-definition.create') }}"; --}}
storeDefinitionFormData(token, baseUrl);
// console.log(addUrl);
});
</script>
错误
Request URL:http://127.0.0.1:8000/participant/project-definition/create/2kxMQc4GvAD13LZC733CjWYLWy8ZzhLFsvmOj3oT
Request method:POST

【问题讨论】：
-
你的这条路线
Route::get('/store-project-definition-data/{id}'.....是post吗？如果它尝试更新到Route::post(.... -
@Vipertecpro 是的，我尝试过 POST，但它显示错误消息“此路由不支持 GET 方法。支持的方法：POST”
-
您是否尝试访问 GET 方法？
-
是的，但我没有工作
-
我不明白你为什么要通过 ajax 调用 GET 方法？ ajax 假设只调用 POST、PUT、PATCH、DELETE 方法。你想通过 ajax 调用 GET 方法来达到什么目的？
