這次要介紹如何將照片上傳到特定的伺服器，本篇文章使用上傳方式是目前最常用的http post
相當多API都使用這類方式

實作說明

繼上篇：ESP32-CAM(ardunio)拍照auto take picture、串流stream及物件辨識object，能拍照並存檔，這次要介紹如何將照片上傳到特定的伺服器，本篇文章使用上傳方式是目前最常用的http post，相當多API都使用這類方式，當然另外有其他方式待以後在介紹。

要完成本篇文章，請依序完成以下主題

ESP32-CAM環境建立與範例測試： Build a Video Stream Server by ESP32-CAM (arduino)影像伺服器及臉部辨識
ESP32-CAM拍照及SDcard存檔：ESP32-CAM(ardunio)拍照auto take picture、串流stream及物件辨識object

完成以上測試後，就可以進行以下內容，以下內容主要分成一、ESP32-CAM端及二、伺服器接收端，ESP32-CAM拍照後，將檔案以HTTP POST方式上傳到伺服器，因此你必須準備一台電腦並安裝web服務，以下分別介紹

操作流程

一、ESP32-CAM部份

ESP32-CAM主要進行拍照存檔並上傳，拍照可定時拍照，或像「ESP32-CAM(ardunio)拍照auto take picture、串流stream及物件辨識object」以人體感測進行拍照，本範例簡單起見，採用每30秒定時拍照。範例程式放在本篇最後方，請注意，須修改以下內容：

第66-67，請修改成自己的wifi設定的SSID與密碼
第68-69，請修改成自己的web server的IP(或DNS)與接收照片的html檔案的URL。
loop（1211-1220）區塊中，目前以30s自動拍照，若有需要可以刪除第1213及1219的if區塊註解。
本文主要多了一隻副程式「wifisendfile」進行檔案上傳，wifisendfile需要三個參數，分別是檔案位置與名稱、上傳伺服器IP以及接收照片的HTML檔案位置。

二、伺服器接收端

伺服器的實做，有很多選擇，可以用linux+PHP或者windows+IIS+APS.net等等，由於本人比較熟悉.net平台，因此以下介紹如何利用asp.net來接收ARDUINO傳來的檔案。

首先電腦必須安裝IIS或IIS express，安裝流程可參閱： http://charlesbc.blogspot.com/2011/01/iis-express_16.html
.net安裝開發環境，目前包括VS.net 2017或2019，都有社群免費版可以選擇，下載網址： https://visualstudio.microsoft.com/zh-hant/downloads/?utm_medium=microsoft&utm_source=docs.microsoft.com&utm_campaign=button+cta&utm_content=download+vs2019&rr=https%3A%2F%2Fdocs.microsoft.com%2Fzh-tw%2Fvisualstudio%2Finstall%2Finstall-visual-studio%3Fview%3Dvs-2019

Visual Studio 社群免費版下載

安裝時，請至少選擇以下幾個模組，其餘您自行斟酌是否需要安裝，VS.net是一個宇宙最肥沒有之一的開發平台，安裝時請注意自己的硬碟空間

選擇VS.net

完成安裝後，啟動VS.net主程式，並開啟本地端IIS站，就可進行下一步。

啟動VS.net主程式
開啟本地端IIS站

ASP檔案接收的程式部份，由於本人已經是old school了，就以最擅長的vb.net寫範例程式。

    Private Sub default_Load(sender As Object, e As EventArgs) Handles Me.Load
        '0檔案上傳處理
        Dim aFile As HttpFileCollection = Request.Files
        If aFile.Count > 0 Then
            Dim relativePath As String = "files\"
            Dim absolutePath As String = Server.MapPath("~/" + relativePath)
            Dim displayFileName As String = Path.GetFileName(aFile(0).FileName)
            Dim filename As String = Int(Now().Ticks) & ".jpg"
            Dim realFileName As String = absolutePath & filename
            aFile(0).SaveAs(realFileName) 
        End If
    End Sub

檔案上傳後，會存在伺服器中，就可以用來做很多的功能，例如轉存到azure做智慧辨識、送到LINE裡面做通知等等。
不過呢，一次檔案的POST，需要大概5秒鐘時間，因此不適合用來做即時化的服務。
