我目前正在使用个人资料图片上传功能在android上进行注册活动。我成功完成了上传和注册，该保存在数据库中，并保存到我为个人资料图片设置的文件路径中，但是这会导致一些延迟，导致某些参数重复执行我认为正在执行的操作。因为我注意到它已成功上传并保存到数据库，但没有收到成功消息，而是返回了电子邮件上的错误验证：“电子邮件已存在” 。
public function storeuser(Request $request){
$valid = $this->validateRequest($request);
if($valid){
if(!User::all()->where('Email', '=', $valid['email'])->first()){
$userinsert = new User();
$userinsert->firstname = $valid['firstname'];
$userinsert->lastname = $valid['lastname'];
$userinsert->email = $valid['email'];
$userinsert->password = bcrypt($valid['password']);
$userinsert->mobile = $valid['mobile'];
$userinsert->status = 0;
$userinsert->activationno = str_random(30);
$userinsert->usertypeid = 2;
if($userinsert->save()){
$userinsert->sendVerificationEmail();
$this->storeImage($userinsert);
return response()->json(['status' => "good" ,'success' => "Account Registered, Please verify email" ]);
}
else{
return back()->withErrors();
}
}
else{
return response()->json(['email' => "Email already exists"]);
}
}
else{
return response()->withErrors();
}
}
private function storeImage($profilepic)
{
$target = "profilepic";
$target = $target ."/". rand()."_".time(). ".jpeg";
if (request()->has('profile')) {
$profilepic->update([
'ProfilePicture' => $target,
]);
$add_to_public = "public/".$target;
$img = \Storage::put($add_to_public, base64_decode(request()->profile));
$profilepic->save();
}
}
这是Java的代码
