当我尝试将下一个请求发送到API时:

https://api.instagram.com/v1/tags/nofilter/media/recent?access_token=MY_TOKEN

以下错误apeear:

{"meta":{"error_type":"OAuthPermissionsException","code":400,"error_message":"This request requires scope=public_content, but this access token is not authorized with this scope. The user must re-authorize your application with scope=public_content to be granted this permissions."}}

当我试图通过Instagram的安全屏幕(https://instagram.com/developer/clients/MY_CLIENT/edit/)更改应用程序的范围时,会显示以下消息:

We will start accepting Permissions Review submissions after Dec 3, 2016.

我正试图通过我的python应用程序从Instagram API检索数据.当我向Instagram API发送HTTP请求时,它会返回下一个错误:

{"meta":{"error_type":"OAuthAccessTokenException","code":400,"error_message":"The access_token provided is invalid."}}

我的代码附后:

def parseData(self,hashtag):
        url = "https://api.instagram.com/v1/tags/" + hashtag + "/media/recent?client_id=" + self.CLIENT_ID
        content = urllib2.urlopen(url).read()
        data = json.load(content)

我试图获得一个新的身份验证密钥,但我有同样的错误

我有不同分辨率的视频.我希望所有这些都能达到480x320的分辨率.我试过这个命令:

ffmpeg -i %s_ann.mp4 -vf scale=480x320,setsar=1:1 %s_annShrink.mp4' %(dstfile,dstfile)

但视频的输出是大小为0 kb的文件.

我做错了什么？

我有使用 cmake 编译的 C++ 项目。我正在尝试使用相对路径而不是绝对路径链接库。代码编译良好，但在链接库时出现问题。

CMakeLists.txt：

cmake_minimum_required(VERSION 2.8)
project(GMW)
cmake_policy(SET CMP0015 NEW)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -maes -mpclmul -fPIC")

SET (BOOST_ROOT $ENV{HOME}/boost_1_60_0/)
SET (BOOST_INCLUDEDIR $ENV{HOME}/boost_1_60_0/)
SET (BOOST_LIBRARYDIR $ENV{HOME}/boost_1_60_0/stage/lib)
find_package(Boost COMPONENTS system thread REQUIRED)

INCLUDE_DIRECTORIES($ENV{HOME} ${BOOST_INCLUDEDIR}
        ../../lib/OTExtensionBristol ../../lib/)

link_directories(/usr/ssl/lib/ ../../install/lib ${BOOST_LIBRARYDIR})

set(SOURCE_FILES main.cpp GMWParty.h Circuit.cpp Circuit.h MPCCommunication.cpp MPCCommunication.h GMWParty.cpp)
add_executable(GMW ${SOURCE_FILES})
add_library(gmw ${SOURCE_FILES})

TARGET_LINK_LIBRARIES(GMW ../../scapi.a gmp
        OTExtensionBristol
        ../../install/lib/libsimpleot.a
        boost_system boost_thread pthread crypto dl ssl z)

cmake_policy(SET CMP0015 NEW)解决了链接目录的问题。

对于链接库如何解决？

我正在尝试根据某些文件删除重复的行.当我运行以下查询时:

delete
    from slowmo_vid as sv1, slowmo_vid as sv2
    where sv1.video_id = '2luh6g3ni5ex'
    and sv1.slowmo_end_t<=sv2.slowmo_end_t;

我收到错误:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'as sv1, slowmo_vid as sv2
where sv1.video_id = '2luh6g3ni5ex'
and sv1.slowmo_end' at line 2

表的字段是:id,video_id internal_uri,slowmo_end_t

我正在使用 boto3 来部署 Spot 实例。我的请求在一段时间后过期（如我所定义）。当请求到期时，我期望机器将终止。为了创建现场请求，我使用了这个脚本：

client = boto3.client('ec2', region_name=regions[idx][:-1])    
client.request_spot_instances(
                        DryRun=False,
                        SpotPrice=price_bids,
                        InstanceCount=number_of_instances_to_deploy,
                        LaunchSpecification=
                        {
                            'ImageId': amis_id[idx],
                            'KeyName': 'MyKey',
                            'SecurityGroups': ['SG'],
                            'InstanceType': machine_type,
                            'Placement':
                                {
                                    'AvailabilityZone': regions[idx],
                                },
                        },
                        ValidUntil=new_date,
                )

当请求不再有效时，如何终止 Spot 实例？
