iOS開發之使用AFN上傳圖片

//1.創建管理者對象
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];

//2.上傳文件
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:@"userHeader.png", @"userHeader", nil nil];
[manager POST:URL parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

    //上傳文件參數
    [formData appendPartWithFileData:data name:@"userHeader" fileName:@"userHeader.png" mimeType:@"image/jpeg"];

} progress:^(NSProgress * _Nonnull uploadProgress) {

    //打印上傳進度
    CGFloat progress = 100.0 * uploadProgress.completedUnitCount / uploadProgress.totalUnitCount;
    DLog(@"%.2lf%%", progress);

} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

    //請求成功
    DLog(@"請求成功：%@",responseObject);

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

    //請求失敗
    DLog(@"請求失敗：%@",error);

}];

二、多張圖片

[objc] view plain copy

//1.創建管理者對象
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];

//2.上傳文件
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:@"userHeader.png", @"userHeader", @"image.png", @"image", nil nil];
[manager POST:URL parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

    //上傳文件參數
    [formData appendPartWithFileData:data1 name:@"userHeader" fileName:@"userHeader.png" mimeType:@"image/jpeg"];
    [formData appendPartWithFileData:data2 name:@"image" fileName:@"image.png" mimeType:@"image/jpeg"];

} progress:^(NSProgress * _Nonnull uploadProgress) {

    //打印上傳進度
    CGFloat progress = 100.0 * uploadProgress.completedUnitCount / uploadProgress.totalUnitCount;
    DLog(@"%.2lf%%", progress);

} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

    //請求成功
    DLog(@"請求成功：%@",responseObject);

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

    //請求失敗
    DLog(@"請求失敗：%@",error);

}];
