如何在具有文件上传功能的Laravel API中使用PUT方法 [英] How to use PUT method in Laravel API with File Upload
问题描述
已阅读链接，
PUT 最常用于更新功能，将请求体包含到最新的原始资源表示中，将其PUT到已知资源URI.
PUT is most-often utilized for update capabilities, PUT-ing to a known resource URI with the request body containing the newly-updated representation of the original resource.
...我们需要再次发送 所有 数据参数.
... we need to send all the parameters of the data again.
在我的控制器中，我有:
In my controller, I have:
$student = Student::find($student_id);
$student->username = $request->username;
$student->email = $request->email;
$student->password = $request->password;
$path = $request->file('passport')->store('upload');
$student->passport = $path;
我曾经将相同的代码用于 POST 方法，并且可以工作，但是在将其用于API时，我使用了POSTMAN form-data 并获得了 $request-> all()设为 null .有人说我应该使用 x-www-form-urlencoded ，但这不允许文件上传.
I have once used this same code for POST method and it worked, but while using it for APIs, I used POSTMAN form-data and got $request->all() to be null. Some said I should use x-www-form-urlencoded but this does not allow files upload.
推荐答案
这实际上是 PHP本身没有能力.只是带有 multipart/form-data 的PUT/PATCH请求不会填充 $ _ FILES ，因此Laravel无法使用.
This is actually an incapability of PHP itself. A PUT/PATCH request with multipart/form-data just will not populate $_FILES, so Laravel has nothing to work with.
文件最好以 multipart/form-data 发送，并且如果是POST，则只会填充 $ _ FILES .
Files are best sent as multipart/form-data and that will only populate $_FILES if it's a POST.
显然， $ request-> all()返回null的事实是
Apparently the fact that $request->all() returns null is a known issue in Laravel.
如果在Laravel中解决此问题，则可以使用POST.
In lieu of fixing this in Laravel, if it works using a POST, just use a POST.
