如何在图像中转换视图文件并在laravel中返回api [英] how to convert view file in image and return in api in laravel
问题描述
我正在laravel中创建一个API。其中，我必须将刀片文件转换为图像，并应在api中返回转换后的图像或base64的路径。
I am creating an API in laravel. In which, I have to convert blade file into image and should return path of converted image or base64 in api.
我正在使用html2canvas。
I am using html2canvas.
路线是：
$router->POST('savecard', 'HomeController@SaveCard');
$router->get('save-capture/{image_for_save}', 'HomeController@savecapture');
我必须通过 POSTMAN 呼叫保存卡并运行一些代码，然后我有一个刀片文件template1.blade.php
I have to call savecard by POSTMAN and run some code and then I have a blade file template1.blade.php
我的控制器是：
public function SaveCard(Request $request)
{
$find_edittemplate_id = edittemplate::select('id')->where('user_id','=',$request->user_id)->first();
return view('template1');
}
public function savecapture($image_for_save)
{
$image = $image_for_save;
$image = explode(";", $image)[1];
// Remove base64 from left side of image data
// and get the remaining part
$image = explode(",", $image)[1];
// Replace all spaces with plus sign (helpful for larger images)
$image = str_replace(" ", "+", $image);
// Convert back from base64
$image = base64_decode($image);
$destinationPath = storage_path('uploads/');
file_put_contents($destinationPath,'temp.png',$image);
return response()->json(['CardSave' => $image, 'message' => 'Success'], 201);
}
查看template1文件后，我创建了ajax调用，将图像转换为template1.blade .php。
After view template1 file, I created ajax call for convert image to template1.blade.php.
savecapture（）将由ajax在template1.blade.php上运行
savecapture() will run on template1.blade.php by ajax
视图为：

<title>Template One</title>

<script>
$(document).ready(function() {
window.scrollTo(0, 0);
html2canvas(document.getElementById("mydiv_screenshot")).then(function (canvas) {
var ajax = new XMLHttpRequest();
var image_data = canvas.toDataURL("image/jpeg", 0.9);
$.ajax({
url: '{{ url("save-capture") }}',
type: 'GET',
data: {"image_for_save": image_data},
success: function(response){
if(response != 0){
//console.log(response);
}else{
//console.log(response);
}
},
async: true
});
});
});
</script>
但是它在邮递员中显示完整的刀片文件，并且不运行ajax。
But It show in postman complete blade file and also not run ajax.
推荐答案
我必须将刀片文件转换为图像
I have to convert blade file into image
刀片文件由服务器上的Laravel处理。没有直接的方法可以将它们转换为图像。
Blade files are processed by Laravel on server. There is no direct way to convert them in images.
我在核心php中使用了htmlcanvas。但是我对laravel一无所知。
I have used htmlcanvas in core php. But I have no idea in laravel.
PHP没有此功能。 HtmlCanvas是浏览器DOM的一部分。除非您使用了一些自定义的PHP扩展，否则我想您要做的就是在浏览器中使用javascript / canvas创建图像，然后将其发送到服务器（这也是Laravel的方法）。
PHP doesn't have this functionality. HtmlCanvas is part of browser DOM. Unless you've used some custom PHP extension, what I think you did was creating the image on browser using javascript/canvas and then send it to the server (which is exactly the way to go with Laravel as well).
