使用 twitter api 时 Python flask 返回 405 错误

如何解决使用 twitter api 时 Python flask 返回 405 错误

我正在使用 python，我很抱歉，因为这可能是一个我没有掌握的非常简单的概念，但我对 Flask 框架不是很熟悉。现在我正在用 Flask 制作一个服务器，但每次我尝试用 twitter api 做一些事情后不久都会遇到 405 错误。现在我的代码看起来像这样

在一个单独的文件中：

from flask import Flask
from threading import Thread

app = Flask('')

@app.route('/',methods=['GET','POST','DELETE'])
def home():
    return "Hello world!"

def run():
  app.run(host='0.0.0.0',port=8080)
  app.run(debug=True,host="0.0.0.0")

def keep_alive():
    t = Thread(target=run)
    t.start()

然后我在主文件中调用我的代码：

from flaskfile import flask_file
flask_file()

MEDIA_ENDPOINT_URL = 'https://upload.twitter.com/1.1/media/upload.json'
POST_TWEET_URL = 'https://api.twitter.com/1.1/statuses/update.json'

CONSUMER_KEY = consumerkey
CONSUMER_SECRET = secret
ACCESS_TOKEN = accesstoken
ACCESS_TOKEN_SECRET = tokensecret


#fileName = check_and_download()
VIDEO_FILENAME = (filename)


oauth = OAuth1(CONSUMER_KEY,client_secret=CONSUMER_SECRET,resource_owner_key=ACCESS_TOKEN,resource_owner_secret=ACCESS_TOKEN_SECRET)


class VideoTweet(object):

  def __init__(self,file_name):
    '''
    Defines video tweet properties
    '''
    self.video_filename = file_name
    self.total_bytes = os.path.getsize(self.video_filename)
    self.media_id = None
    self.processing_info = None


  def upload_init(self):
    '''
    Initializes Upload
    '''
    print('INIT')

    request_data = {
      'command': 'INIT','media_type': 'video/mp4','total_bytes': self.total_bytes,'media_category': 'tweet_video'
    }

    req = requests.post(url=MEDIA_ENDPOINT_URL,data=request_data,auth=oauth)
    media_id = req.json()['media_id']

    self.media_id = media_id

    print('Media ID: %s' % str(media_id))


  def upload_append(self):
    '''
    Uploads media in chunks and appends to chunks uploaded
    '''
    segment_id = 0
    bytes_sent = 0
    file = open(self.video_filename,'rb')

    while bytes_sent < self.total_bytes:
      chunk = file.read(4*1024*1024)
      
      print('APPEND')

      request_data = {
        'command': 'APPEND','media_id': self.media_id,'segment_index': segment_id
      }

      files = {
        'media':chunk
      }

      req = requests.post(url=MEDIA_ENDPOINT_URL,files=files,auth=oauth)

      if req.status_code < 200 or req.status_code > 299:
        print(req.status_code)
        print(req.text)
        sys.exit(0)

      segment_id = segment_id + 1
      bytes_sent = file.tell()

      print('%s of %s bytes uploaded' % (str(bytes_sent),str(self.total_bytes)))

    print('Upload chunks complete.')


  def upload_finalize(self):
    '''
    Finalizes uploads and starts video processing
    '''
    print('FINALIZE')

    request_data = {
      'command': 'FINALIZE','media_id': self.media_id
    }

    req = requests.post(url=MEDIA_ENDPOINT_URL,auth=oauth)
    print(req.json())

    self.processing_info = req.json().get('processing_info',None)
    self.check_status()


  def check_status(self):
    '''
    Checks video processing status
    '''
    if self.processing_info is None:
      return

    state = self.processing_info['state']

    print('Media processing status is %s ' % state)

    if state == u'succeeded':
      return

    if state == u'failed':
      sys.exit(0)

    check_after_secs = self.processing_info['check_after_secs']
    
    print('Checking after %s seconds' % str(check_after_secs))
    time.sleep(check_after_secs)

    print('STATUS')

    request_params = {
      'command': 'STATUS','media_id': self.media_id
    }

    req = requests.get(url=MEDIA_ENDPOINT_URL,params=request_params,auth=oauth)
    
    self.processing_info = req.json().get('processing_info',None)
    self.check_status()


  def tweet(self):
    '''
    Publishes Tweet with attached video
    '''
    request_data = {
        #leave status blank
      'status': '','media_ids': self.media_id
    }

    req = requests.post(url=POST_TWEET_URL,auth=oauth)
    print(req.json())


if __name__ == '__main__':
  videoTweet = VideoTweet(VIDEO_FILENAME)
  videoTweet.upload_init()
  videoTweet.upload_append()
  videoTweet.upload_finalize()
  videoTweet.tweet()
  

返回的错误说明如下：

"错误响应

错误代码：405

消息：方法不允许。

错误代码解释：405 - 指定的方法对该资源无效。”

基本上我调用flask文件然后使用twitter api上传文件，但由于某种原因使用twitter api总是导致405错误并且我的flask服务器无法再访问。如何调整我的烧瓶文件以允许我使用 api 上传？

解决方法

使用错误的请求方法时会抛出 405 错误。例如，在预期 GET 请求时发送 POST 请求，或在预期 POST 请求时发送 GET 请求。

在您的 check_status 函数中

req = requests.get(url=MEDIA_ENDPOINT_URL,...

但根据 Twitter's documentation 你应该在这里使用 post 请求

req = requests.post(url=MEDIA_ENDPOINT_URL,...
