緣起
今天用暴風影音看視頻,然后發現它有個功能,wifi傳片,感覺挺有意思,然后就上網查了下相關內容。
原理
使用CocoaHTTPServer框架,在iOS端建立一個本地服務器,只要電腦和手機連入同一熱點或者說網絡,就可以實現通過電腦瀏覽器訪問iOS服務器的頁面,利用POST實現文件的上傳。
實現
1.下載CocoaHTTPServer
2.導入CocoaHTTPServer-master目錄下的Core文件夾
3.導入Samples/SimpleFileUploadServer目錄下的MyHTTPConnection類文件和web文件夾
4.導入Vendor目錄下的CocoaAsyncSocket、CocoaLumberjack文件夾
5.打開MyHTTPConnection.m文件,根據標記 #pragma mark multipart form data parser delegate 跳轉或者直接找到139行的 *- (void) processStartOfPartWithHeader:(MultipartMessageHeader ) header 方法,把第151行的uploadDirPath改為
1
|
NSString *uploadDirPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject]; |
這個路徑是上傳文件的存儲路徑
6.在適當的地方配置server啟動。這里以AppDelegate為例

7.運行后,控制臺會打印出端口號和ip,在電腦端瀏覽器里輸入ip+端口號訪問即可,如果成功的話會看到如下界面:
8.如果上傳成功,網頁上會出現上傳的文件名,可以在沙盒里驗證文件是否上傳成功
