PHP -- 上传文件接口编写 及 iOS -- 端上传图片AF实现

Posted 2020-08-09

php 上传文件接口:

//保存图片
$json_result [‘status‘] = 0;
$path = ‘upfile‘;
$json_result [‘status‘] = 0;
$json_result [‘successmsg‘] = ‘上传失败‘;
if (isset ( $_FILES [‘image‘] )) {
    $upfile = ‘upfile/‘ . $_FILES [‘image‘] [‘name‘];
    if (! @file_exists ( $path )) {
        @mkdir ( $path );
    }
    $result = @move_uploaded_file ( $_FILES [‘image‘] [‘tmp_name‘], $upfile );
    if (! $result) {
        $json_result [‘status‘] = 0;
        $json_result [‘successmsg‘] = ‘上传失败‘;
        $json_result [‘datas‘] = array (‘savePath‘ => $upfile );
        exit ( json_encode ( $json_result ) );
    }
}


$json_result [‘status‘] = 1;
$json_result [‘datas‘] = array (‘savePath‘ => "http://".$_SERVER[‘SERVER_NAME‘].":".$_SERVER[‘SERVER_PORT‘]."/".$upfile );
print_r(json_encode($json_result));

ios通过接口上传图片:

// 上传头像
- (void)uploadUserHeadImage:(UIImage *)image {
    // 获得网络管理者
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    
    // 设置请求参数
    NSMutableDictionary *params = [NSMutableDictionary dictionary];
    
    [manager POST:@"http://localhost:8888/upload_image.php" parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
        
        // 获取图片数据
        NSData *fileData = UIImageJPEGRepresentation(image, 1.0);
        
        // 设置上传图片的名字
        NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
        formatter.dateFormat = @"yyyyMMddHHmmss";
        NSString *str = [formatter stringFromDate:[NSDate date]];
        NSString *fileName = [NSString stringWithFormat:@"%@.png", str];
        
        [formData appendPartWithFileData:fileData name:@"image" fileName:fileName mimeType:@"image/png"];
        
    } progress:^(NSProgress * _Nonnull uploadProgress) {
        NSLog(@"%@", uploadProgress);
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        // 返回结果
        NSLog(@"%@", responseObject[@"datas"]);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"%@", error);
    }];
}
