關於android內建微信瀏覽器，10秒自動重複提交的大坑，簡單出爆，幹掉他
先說說這個機制問題，10秒超時，微信瀏覽器會自動使用代理進行提交，並且會打斷第一次提交，如果你是訂單的話，你就只能呵呵了。
我就是有個功能，上傳一堆的附件到oss去，結果超過10s了，你會發現時間越來越久，原來微信給你再次提交，訂單直接報id錯誤。
移動端的ie6，不想說什麼了，直接貼程式碼：
/**
* 儲存車輛申請記錄
*/
@CheckLogin
@Certification
@RequestMapping(value="/saveApply",method=RequestMethod.POST)
public void saveApply(
LoanApplicationRecord loanApplicationRecord
,@RequestParam String CAR_POSITIVE
,@RequestParam String CAR_BACK
,@RequestParam String CAR_LEFT
,@RequestParam String CAR_RIGHT
,@RequestParam String ENGINE_NAMEPLATE
,@RequestParam String VEHICLE_REGISTRATION_FRONT
,@RequestParam String VEHICLE_REGISTRATION_BACK
,@RequestParam String DRIVING_PERMIT
,@RequestParam String VEHICLE_PURCHASE_CONTRACT
,String LOAN_FILE_OTHER
,HttpServletRequest request
,HttpServletResponse response){
ResultVO rv = ResultVO.getFailInstance();
try {
/**
* 開始儲存申請記錄
*/
loanApplicationRecordService.submit(getSessionUserID(request)
,loanApplicationRecord);
// 登入成功
rv.setSuccess();
}catch(BusinessRuntimeException e){
rv.setMsg(e.getMessage());
}catch (Exception e) {
// 未知異常，列印日誌，返回系統錯誤
LogUtils.error(e.getMessage());
rv.setSysError();
}
try{
// 重點就是在這裡........ 直接儲存記錄返回結果，夠簡單粗暴吧，
//前提是你要保證下面的程式碼沒啥問題，反正我是沒法保證了。
//反正就幾個檔案，大不了重新叫他上傳吧。哈哈
response.getWriter().print(rv.toJson());
response.getWriter().flush();
response.getWriter().close();
// 這裡就不管能不能成功了。這麼多檔案，管他呢，我只能說，秒傳，what the fuck ...WX
// 這裡進行檔案的上傳，時間過長，故先返回結果。
