Saving blob image in laravel's controller - laravel-5

Question

In my Laravel 5/vuejs 2.6 I upload an image with the vue-upload-component and am sending a requested image blob
I try to save it with the controller code like :
if ( !empty($requestData['avatar_filename']) and !empty($requestData['avatar_blob']) ) {
$dest_image = 'public/' . Customer::getUserAvatarPath($newCustomer->id, $requestData['avatar_filename']);
$requestData['avatar_blob']= str_replace('blob:','',$requestData['avatar_blob']);
Storage::disk('local')->put($dest_image, file_get_contents($requestData['avatar_blob']));
ImageOptimizer::optimize( storage_path().'/app/'.$dest_image, null );
} // if ( !empty($page_content_image) ) {
As result, I have an image uploaded, but it is not readable.
The source file has 5 Kib, the resulting file has 5.8 Kib and in the browser's console I see the blobs path as
avatar_blob: "blob:http://local-hostels2.com/91a18493-36a7-4023-8ced-f5ea4a3c58af"
Have do I convert my blob to save it correctly?
MODIFIED :
a bit more detailed :
In vue file I send request using axios :
let customerRegisterArray =
{
username: this.previewCustomerRegister.username,
email: this.previewCustomerRegister.email,
first_name: this.previewCustomerRegister.first_name,
last_name: this.previewCustomerRegister.last_name,
account_type: this.previewCustomerRegister.account_type,
phone: this.previewCustomerRegister.phone,
website: this.previewCustomerRegister.website,
notes: this.previewCustomerRegister.notes,
avatar_filename: this.previewCustomerRegister.avatarFile.name,
avatar_blob: this.previewCustomerRegister.avatarFile.blob,
};
console.log("customerRegisterArray::")
console.log(customerRegisterArray)
axios({
method: ('post'),
url: window.API_VERSION_LINK + '/customer_register_store',
data: customerRegisterArray,
}).then((response) => {
this.showPopupMessage("Customer Register", 'Customer added successfully ! Check entered email for activation link !', 'success');
alert( "SAVED!!::"+var_dump() )
}).catch((error) => {
});
and this.previewCustomerRegister.avatarFile.blob has value: "blob:http://local-hostels2.com/91a18493-36a7-4023-8ced-f5ea4a3c58af"
where http://local-hostels2.com is my hosting...
I set this value to preview image defined as :
<img
class="img-preview-wrapper"
:src="previewCustomerRegister.avatarFile.blob"
alt="Your avatar"
v-show="previewCustomerRegister.avatarFile.blob"
width="256"
height="auto"
id="preview_avatar_file"
>
and when previewCustomerRegister.avatarFile.blob is assigned with uploaded file I see it in preview image.
I show control with saving function in first topic but when I tried to opened my generated file with kate, I found that it
has content of my container file resources/views/index.blade.php...
What I did wrong and which is the valid way ?
MODIFIED BLOCK #2 :
I added 'Content-Type' in request
axios({
method: ('post'),
url: window.API_VERSION_LINK + '/customer_register_store',
data: customerRegisterArray,
headers: {
'Content-Type': 'multipart/form-data'
}
but with it I got validation errors in my control, as I define control action with request:
public function store(CustomerRegisterRequest $request)
{
and in app/Http/Requests/CustomerRegisterRequest.php :
<?php
namespace App\Http\Requests;
use App\Http\Traits\funcsTrait;
use Illuminate\Foundation\Http\FormRequest;
use App\Customer;
class CustomerRegisterRequest extends FormRequest
{
use funcsTrait;
public function authorize()
{
return true;
}
public function rules()
{
$request= Request();
$requestData= $request->all();
$this->debToFile(print_r( $requestData,true),' getCustomerValidationRulesArray $requestData::');
/* My debugging method to write data to text file
and with Content-Type defined above I see that $requestData is always empty
and I got validations errors
*/
// Validations rules
$customerValidationRulesArray= Customer::getCustomerValidationRulesArray( $request->get('id'), ['status'] );
return $customerValidationRulesArray;
}
}
In routes/api.php defined :
Route::post('customer_register_store', 'CustomerRegisterController#store');
In the console of my bhrowser I see : https://imgur.com/a/0vsPIsa, https://imgur.com/a/wJEbBnP
I suppose that something is wrong in axios header ? without 'Content-Type' defined my validation rules work ok...
MODIFIED BLOCK #3
I managed to make fetch of blob with metod like :
var self = this;
fetch(this.previewCustomerRegister.avatarFile.blob) .then(function(response) {
console.log("fetch response::")
console.log( response )
if (response.ok) {
return response.blob().then(function(myBlob) {
var objectURL = URL.createObjectURL(myBlob);
// myImage.src = objectURL;
console.log("objectURL::")
console.log( objectURL )
console.log("self::")
console.log( self )
let customerRegisterArray =
{
username: self.previewCustomerRegister.username,
email: self.previewCustomerRegister.email,
first_name: self.previewCustomerRegister.first_name,
last_name: self.previewCustomerRegister.last_name,
account_type: self.previewCustomerRegister.account_type,
phone: self.previewCustomerRegister.phone,
website: self.previewCustomerRegister.website,
notes: self.previewCustomerRegister.notes,
avatar_filename: self.previewCustomerRegister.avatarFile.name,
avatar: objectURL,
};
console.log("customerRegisterArray::")
console.log(customerRegisterArray)
axios({
method: 'POST',
url: window.API_VERSION_LINK + '/customer_register_store',
data: customerRegisterArray,
// headers: {
// 'Content-Type': 'multipart/form-data' // multipart/form-data - as we need to upload with image
// }
}).then((response) => {
self.is_page_updating = false
self.message = ''
self.showPopupMessage("Customer Register", 'Customer added successfully ! Check entered email for activation link !', 'success');
alert( "SAVED!!::")
}).catch((error) => {
self.$setLaravelValidationErrorsFromResponse(error.response.data);
self.is_page_updating = false
self.showRunTimeError(error, this);
self.showPopupMessage("Customer Register", 'Error adding customer ! Check Details fields !', 'warn');
// window.grecaptcha.reset()
self.is_recaptcha_verified = false;
self.$refs.customer_register_wizard.changeTab(3,0)
});
});
} else {
return response.json().then(function(jsonError) {
// ...
});
}
}).catch(function(error) {
console.log('There has been a problem with your fetch operation: ', error.message);
});
In objectURL and self I see proper values : https://imgur.com/a/4YvhbFz
1) But checking data on server in laravel's control I see the same values I had at start of my attemps to upload image:
[avatar_filename] => patlongred.jpg
[avatar] => blob:http://local-hostels2.com/d9bf4b66-42b9-4990-9325-a72dc8c3a392
Have To manipulate with fetched bnlob in some other way ?
2) If I set :
headers: {
'Content-Type': 'multipart/form-data'
}
I got validation errors that my data were not correctly requested...
?

Answer 1

You're using request type as application/json hence you won't be able to save the image this way, for a file upload a request type should be multipart/form-data in this case you'll need to send request as
let customerRegisterArray = new FormData();
customerRegisterArray.put('username', this.previewCustomerRegister.username);
customerRegisterArray.put('email', this.previewCustomerRegister.email);
....
customerRegisterArray.put('avatar', this.previewCustomerRegister.avatarFile);
console.log("customerRegisterArray::")
console.log(customerRegisterArray)
axios({
method: ('post'),
url: window.API_VERSION_LINK + '/customer_register_store',
data: customerRegisterArray,
headers: {
'Content-Type': 'multipart/form-data'
}
}).then((response) => {
this.showPopupMessage("Customer Register", 'Customer added successfully !Check entered email for activation link !', 'success');
alert( "SAVED!!::"+var_dump() )
}).catch((error) => {});

Thank you for your help!
Valid decision was :
var self = this;
fetch(this.previewCustomerRegister.avatarFile.blob) .then(function(response) {
if (response.ok) {
return response.blob().then(function(myBlob) {
var objectURL = URL.createObjectURL(myBlob);
let data = new FormData()
data.append('username', self.previewCustomerRegister.username)
data.append('email', self.previewCustomerRegister.email)
data.append('first_name', self.previewCustomerRegister.first_name)
data.append('last_name', self.previewCustomerRegister.last_name)
data.append('account_type', self.previewCustomerRegister.account_type)
data.append('phone', self.previewCustomerRegister.phone)
data.append('website', self.previewCustomerRegister.website)
data.append('notes', self.previewCustomerRegister.notes)
data.append('avatar_filename', self.previewCustomerRegister.avatarFile.name)
data.append('avatar', myBlob)
axios({
method: 'POST',
url: window.API_VERSION_LINK + '/customer_register_store',
data: data,
headers: {
'Accept': 'application/json',
'Content-Type': 'multipart/form-data' // multipart/form-data - as we need to upload with image
}
}).then((response) => {
self.is_page_updating = false
self.message = ''
self.showPopupMessage("Customer Register", 'Customer added successfully ! Check entered email for activation link !', 'success');
alert( "SAVED!!::123")
// self.$router.push({path: '/'});
}).catch((error) => {
self.$setLaravelValidationErrorsFromResponse(error.response.data);
self.is_page_updating = false
self.showRunTimeError(error, this);
self.showPopupMessage("Customer Register", 'Error adding customer ! Check Details fields !', 'warn');
window.grecaptcha.reset()
self.is_recaptcha_verified = false;
self.$refs.customer_register_wizard.changeTab(3,0)
});
});
} else {
return response.json().then(function(jsonError) {
// ...
});
}
}).catch(function(error) {
console.log('There has been a problem with your fetch operation: ', error.message);
});
and common laravel's file uploading functionality :
$customerAvatarUploadedFile = $request->file('avatar');
...
