為什么Nginx無法在AJAX請求中使用base64圖像（Laravel，Javascript，Nginx）

Question

所有其他AJAX請求（登錄，注冊，basicInformation，educationDetail等）均已成功完成，但是當我上傳個人資料圖片（base64）並發送到laravel控制器時，nginx服務器無法正常工作並返回錯誤...我不知道在哪里我錯過了一些東西。我增加了上傳文件的大小，也增加了緩沖區的大小，但是所有時間響應都相同。 請幫我 ...

.js中的裁剪圖像功能

 jQuery('.cropped_image').on('click', function (ev) {

你能通過做確認路線嗎

PHP的工匠路線：：列表

。 如果路由不存在，請嘗試以下命令。

php artisan cache:clear

php artisan route:cache

希望能幫助到你。 干杯！

更新，我看到問題出在您的代碼中。您可以使用以下代碼從輸入獲取圖像。 （我假設這就是您想要做的）

$base64img = $request->input('image');

        if($base64img){
            // get the base-64 from data
            $file = substr($base64img, strpos($base64img ,",")+1);

            // decode base64 string
            $image = base64_decode($file); 

            $pos = strpos($base64img, ';');
            $imageType = explode('/', substr($base64img, 0, $pos))[1];
