Laravel 5 在laravel'中保存水滴图像；s控制器

在我的Laravel 5/vuejs 2.6中，我使用vue上载组件上载了一个图像，并发送了一个请求的图像块 我尝试使用控制器代码保存它，如：

    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) ) {

因此，我上传了一个图像，但它不可读。 源文件有5 Kib，结果文件有5.8 Kib，在浏览器的控制台中，我看到blob路径如下

avatar_blob: "blob:http://local-hostels2.com/91a18493-36a7-4023-8ced-f5ea4a3c58af"

我是否已转换blob以正确保存它

已修改： 更详细一点： 在vue文件中，我使用axios发送请求：

               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) => {
                });

而this.previewCustomerRegister.avatarFile.blob的值为：“blob：” 我的主机在哪里。。。 我将此值设置为预览图像，定义为：

            <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"
            >

但使用它，我的控件中出现了验证错误，因为我使用请求定义了控件操作：

public function store(CustomerRegisterRequest $request)
{

在app/Http/Requests/CustomerRegisterRequest.php中：

<?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;
    }
}

在我的浏览器控制台中，我看到：

我想axios头有问题吧？如果未定义“内容类型”，我的验证规则正常工作

修改块#3

我设法和我一起把那团东西取出来，我想：

            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);
            });

在objectURL和self中，我看到了正确的值：

1） 但在检查laravel控制的服务器上的数据时，我看到的值与我尝试上传图像时的值相同：

[avatar_filename]=>patlongred.jpg [化身]=>水滴：

必须以其他方式处理获取的bnlob吗

2） 如果我设置：

  headers: {
    'Content-Type': 'multipart/form-data'
  }

我收到验证错误，我的数据请求不正确

？

您使用的请求类型为

应用程序/json

，因此您无法以这种方式保存图像，对于文件上载，请求类型应为

多部分/表单数据

，在这种情况下，您需要以

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) => {});

谢谢你的帮助

有效的决定是：

        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);
        });

和common laravel的文件上载功能：

$customerAvatarUploadedFile = $request->file('avatar');
...

请看我仍然在搜索的决定。谁在控制laravel的情况下使用vue上载组件文件并在vuejs中上载？如何保存使用vue上载组件上载的blob图像？请分享工作示例…这是一个重复：你真的需要粘贴那么多代码吗？谢谢你的帮助！请根据您的

MODIFIED BLOCK#2

查看MODIFIED BLOCK#2，因为您发送的请求仍然错误，您不能在请求中发送带有“多部分/表单数据”的JSON对象，也不能发送Blob URL来上载文件，您需要发送上载的文件，有关更多详细信息，您可以在我使用vue upload组件时参考此线程，它保留blob的url（我在表单上预览了此上载文件），这似乎很棘手。如何将blob转换为上载的文件？您可能可以执行

fetch（blobUrl）。然后（res=>res.blob（））.catch（err=>{//handle err}）

但您尚未正确发送请求，它将始终以这种方式抛出错误。您不能使用

JSON

发送包含

multipart/form data

的http请求。您应该使用

new FormData（）

创建表单对象，然后发送请求
