我正在尝试使用axios提交表单请求，对其进行验证，如果验证失败，则返回错误。问题是，当我提交表单时，不会返回任何错误消息供我在客户端显示。这是 HTTP请求和vue组件：
<div class="card">
<div class="card-header">
<h4>Information</h4>
</div>
<div class="card-body">
<p v-if='!isEditMode'><strong>Name:</strong> {{businessData.name}}</p>
<div class="form-group" v-if='isEditMode'>
<strong><label for="business-name">Name</label></strong>

</div>
</div>
</div>
<div class="card">
<h4 class="card-header">Address Information</h4>
<div class="card-body">

<p v-if="!isEditMode"><strong>State: </strong> {{businessData.state}}</p>
<div class="form-group" v-if='isEditMode'>
<strong><label for="business-state">State: </label></strong>

<div class="card">

</div>
</div>
</div>
</div>
<script>
export default {
data () {
return {
isEditMode: false,
businessData: this.business,
userData: this.user,
errors: []
}
},
props: {
business: {},
user: {},
role: {}
},
//Todo - Institute client side validation that prevents submission of faulty data
methods: {
validateData(data) {
},
saveBusinessEdits () {
axios.put('/businesses/' + this.business.id , {updates: this.businessData})
.then(response => {
console.log(response.data)
// this.businessData = response.data;
this.isEditMode = false;
})
.catch (response => {
console.log(response.data)

})
},
saveUserEdits () {

this.userData = response.data;
this.isEditMode = false;
})
.catch (response => {
console.log(response)
this.isEditMode = false;
})
}
}
}
路线
Route::put('/businesses/{id}', 'BusinessesController@update');
BusinessController和更新功能
public function update(BusinessRequest $request, $id)
{
$business = Business::find($id)->update($request->updates);
$coordinates = GoogleMaps::geocodeAddress($business->street,$business->city,$business->state,$business->zip);
if ($coordinates['lat']) {
$business['latitude'] = $coordinates['lat'];
$business['longitude'] = $coordinates['lng'];
$business->save();
return response()->json($business,200);
} else {
return response()->json('invalid_address',406);
}
$business->save();
return response()->json($business,200);
}
和 BusinessRequest类
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
return [
'business-name'=> 'required|string|max:255',
'business-description'=> 'required|string',
'business-phone' => 'nullable|phone|numeric',
'business-email' => 'nullable|email',
'business-street'=> 'required|string',
'business-city' => 'required|string',
'business-state' => 'required|string|max:2',
'business-zip' => 'required|min:5|max:5|numeric',
];
}
public function messages() {
return [
'business-zip.min:5' =>'your zip code must be a 5 characters long',
'business-email.email'=>'your email is invalid',
'business-phone.numeric'=>'your phone number is invalid',
];
}
}
我不明白为什么即使输入有效数据，它也会返回422响应，并且绝对没有错误消息。由于这是laravel 5.6，因此web.php文件中的所有路由中的“网络”中间件都是自动的。所以这不是问题。有人可以帮我规范化验证行为吗？
答案 0 :(得分：2)
在Laravel中，422状态代码表示表单验证失败。
使用axios，传递给then和catch方法的对象实际上是不同的。要查看错误的响应，您实际上需要具有以下内容：
.catch (error => {
console.log(error.response)
this.isEditMode = false;
})
然后要获取错误（取决于您的Laravel版本），您将具有以下内容：
console.log(error.response.data.errors)

您可以使用Vue.js和axios验证并显示错误。在控制器中有一个名为/ validate-data的路由来验证数据。
app.js文件：
UserID | PPName
-----------------------
1 | SO
1 | GO
1 | PE
2 | SO
2 | GO
3 | SO
3 | GO
3 | PE
使用控制器中的方法创建一个名为/ validate-data的路由，执行标准验证
import Vue from 'vue'
window.Vue = require('vue');
window.axios = require('axios');
window.axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';
let token = document.head.querySelector('meta[name="csrf-token"]');
if (token) {
window.axios.defaults.headers.common['X-CSRF-TOKEN'] = token.content;
} else {
console.error('CSRF token not found: https://laravel.com/docs/csrf#csrf-x-csrf-token');
}
class Errors {
constructor() {
this.errors = {};
}
get(field) {
if (this.errors[field]) {
return this.errors[field][0];
}
}
record(errors) {
this.errors = errors;
}
clear(field) {
delete this.errors[field];
}
has(field) {
return this.errors.hasOwnProperty(field);
}
any() {
return Object.keys(this.errors).length > 0;
}
}
new Vue({
el: '#app',
data:{
errors: new Errors(),
model: {
business-name: '',
business-description: '',
business-phone: ''
},
},
methods: {
onComplete: function(){
axios.post('/validate-data', this.$data.model)
// .then(this.onSuccess)
.catch(error => this.errors.record(error.response.data.errors));
},
}
});
）;
然后使用与vue.js数据模型字段相对应的v-model在视图文件中创建输入。在其下，添加一个带有错误类（例如，基本的红色错误样式）的跨度，该类仅在存在错误的情况下显示。例如：
$this->validate(request(), [
'business-name'=> 'required|string|max:255',
'business-description'=> 'required|string',
'business-phone' => 'nullable|phone|numeric',
'business-email' => 'nullable|email',
'business-street'=> 'required|string',
'business-city' => 'required|string',
'business-state' => 'required|string|max:2',
'business-zip' => 'required|min:5|max:5|numeric'
]
请不要忘记在视图文件的页脚中包含app.js文件。记住要包括标签，然后运行npm run watch来编译vue代码。这将使您可以验证其输入字段下的所有错误。
忘记添加，有一个带有@ onclick =“ onComplete”的按钮来运行validate方法。
