FormData 的不明确行为:将文件数组发送到 API
Unclear Behaviour of FormData: Sending an Array of Files to API
我正在编写一个本机反应应用程序,我应该在其中将一组文件发送到端点。
As with regular form data, you can append multiple values with the same name.
...
This technique makes it simpler to process multi-file uploads because the resultant data structure is more conducive to looping.
因此,我的代码:
data.append('file', document);
// document is a document picker object
// {"size":...,"name":"...","uri":"...","type":"..."}
发送请求时,我收到 500 响应并出现以下错误:
Cannot use object of type Illuminate\Http\UploadedFile as array
用简单的英语来说,端点需要一个数组,但它得到了一个 UploadedFile。 FormData 不是应该发送数组吗?
我的代码有什么错误?
如果您需要更多代码片段,请索取。
从错误信息来看,你的服务器端技术好像是PHP。如果是这样,你可以告诉 PHP file
是一个数组 by adding []
after it,例如:
data.append('file[]', document);
// −−−−−−−−−−−−−−^^
