1.利用pods下載下傳AFN
platform :ios, ‘8.0'
target ‘上傳檔案’ do
pod 'AFNetworking'
end
2
NSString*urlstr=[NSString stringWithFormat:@""];
NSLog(@"%@",urlstr);
//AFN3.0+基于封住HTPPSession的句柄
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
// NSDictionary *dict = @{@"username":@"Saup"};
//formData: 專門用于拼接需要上傳的資料,在此位置生成一個要上傳的資料體
[manager POST:urlstr parameters:nilconstructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
// UIImage *image =[UIImage imageNamed:@"moon"];
// NSData *data = UIImagePNGRepresentation(image);
NSString*path=[[NSBundle mainBundle]pathForResource:@"20170113"ofType:@"doc"];
NSData*fileData=[[NSData alloc] initWithContentsOfFile:path];
NSLog(@"%@",fileData);
NSString*content=[[NSString alloc]initWithData:fileData encoding:NSUTF8StringEncoding];
NSLog(@"%@",content);
// 在網絡開發中，上傳檔案時，是檔案不允許被覆寫，檔案重名
// 要解決此問題，
// 可以在上傳時使用目前的系統事件作為檔案名
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
// 設定時間格式
formatter.dateFormat = @"yyyyMMddHHmmss";
NSString *str = [formatter stringFromDate:[NSDate date]];
NSString *fileName = [NSString stringWithFormat:@"20170113.doc"];
//上傳
//我這兒是doc檔案是以mimeType是application/msword 如果是txt檔案則mimeType是text/plain 具體參考網址//http://tool.oschina.net/commons來确定
[formData appendPartWithFileData:fileData name:@"file" fileName:fileName mimeType:@"application/msword"];
} progress:^(NSProgress * _Nonnull uploadProgress) {
//上傳進度
// @property int64_t totalUnitCount; 需要下載下傳檔案的總大小
// @property int64_t completedUnitCount; 目前已經下載下傳的大小
//
// 給Progress添加監聽 KVO
NSLog(@"%f",1.0 * uploadProgress.completedUnitCount / uploadProgress.totalUnitCount);
// 回到主隊列重新整理UI,使用者自定義的進度條
dispatch_async(dispatch_get_main_queue(), ^{
