PHP

在这部分中，我没有任何尝试捕获的响应，没有错误或问题，但我的文件从未上传到我的文件夹

$data = json_decode(file_get_contents('php://input'), true);
$fileName= $data["avatar"]["filename"];

try {
if(move_uploaded_file(base64_decode($data['avatar']['data']), $finalRute)){
echo 'file update';
}
} catch (Exception $e) {
echo 'Excepción capturada: ',  $e->getMessage(), "n";
} 

Answer 1

在内存中，数据编码为base64。您将不得不采取措施将数据写入磁盘，而不是使用move_uploaded_file，后者是为将磁盘上的临时文件移动到不同位置而设计的。最简单的是file_put_contents。

类似于：

file_put_contents($finalRute, base64_decode(explode(',', $data['avatar']['data'])[1]));

根据AbraCadaver关于省略data:application/pdf;base64,的评论编辑的代码
