PHP 警告：8412174 字节的 POST Content-Length 超出了 Unknow 中 8388608 字节的限制

Question

I'm working on an heroku app thah will run PHP and slim framework to create an REST API service. I have an endpoint that is responsable to accept uploaded files using FormData() on the front-end and that after processing will give the result back to the user so the content can be downloaded. I'm having some trouble with slim and heroku. If I try to upload a png image I will get this error from slim:

PHP Fatal error:  Uncaught RuntimeException:  is not a valid uploaded file in /app/vendor/slim/psr7/src/UploadedFile.php:165

I don't know why this occur, it seems that the file isn't passed to the script, I'm supposing this because there is no file name into the error message, I'm using a library to manage the upload process, the library will accept the Psr7 UploadedFileInterface that is provided by slim when a file is uploaded and works fine in my localhost server, the problem is probably only with slim and I don't know how to fix it.

Another problem is with my heroku dyno settings. I've created a .user.ini file inside the root of the deployed project but I get the error about the POST content length. This is the content of the file:

post_max_size = 20M
upload_max_filesize = 50M
memory_limit = 256M

Is there a way to fix this two problems?

Answer 1

I've found the solution to the problem. I forget to commit the modifications I've made when the .user.ini file was created. I've just prepared all files for commit and then using the terminal I've pushed the updated files to my heroku app.

git commit -am "commit message"
git push heroku master
