ios 中不需要转码~

在iOS开发中，可以使用如下的方式来注册人脸API

- (void)signUpByFacePhoto:(UIImage *)image {

    ///http://ai.baidu.com/docs#/FACE-API/top

    NSURL *url = [NSURL URLWithString:@"https://aip.baidubce.com/rest/2.0/face/v2/faceset/user/add?access_token=24.48afaec56f491332f092314fbdd00fa6.2592000.1514881126.282335-10233570"];

    NSData *imageData = UIImagePNGRepresentation(image);

    NSString *base64Str = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];

    NSMutableDictionary *paramDict = [[NSMutableDictionary alloc] init];

    paramDict[@"uid"] = @"test_uid";

    paramDict[@"group_id"] = @"group_id";

    paramDict[@"user_info"] = @"user_info";

    paramDict[@"image"] = base64Str;

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

    [manager POST:url.absoluteString parameters:paramDict progress:^(NSProgress * _Nonnull uploadProgress) {

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

            NSLog(@"%@", responseObject);

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

    }];

}

图片编码后，还要URL编码提交

这是注册的时候就报错了

新人脸注册后需要稍等一段时间才能生效
