用laravel做圖片上傳的時(shí)候，圖片大于2m的時(shí)候就上傳失敗

不應(yīng)該是這個(gè)錯(cuò)吧?
你小于2M的能傳?
當(dāng)前這個(gè)錯(cuò)是因?yàn)檎?qǐng)求方法不正確,比如定義的POST,你用GET去請(qǐng)求

主要需要改的配置
php中 post_max_size, upload_max_filesize
nginx中 client_max_body_size
改后需要重啟

贊同樓上的說法, 懷疑你報(bào)錯(cuò)信息貼的不正確, MethodNotAllowedHttpException用來判斷請(qǐng)求的METHOD, 跟上傳文件大小沒有關(guān)系, laravel源碼如下
