Download and merge SAE logs using the Python script-Python tutorial

Source: Internet
Author: User
This article mainly introduces how to download and merge SAE logs using a Python script. This article describes the code compilation process and provides the complete code. For more information, see, log files on the site on the SAE can only be downloaded by day from the SAE. it is quite painful to manually download the files, especially when the number is large. Fortunately, SAE provides APIs to obtain log files in batches. after writing a python script, it automatically downloads and merges these files.

Obtain by calling the API

Set your own app and download parameters

The variables to be set in the request are as follows:

The code is as follows:


Api_url = 'http: // dloadcenter.sae.sina.com.cn/interapi.php? '
Appname = 'xxxxx'
From_date = '20140901'
To_date = '201312'
Url_type = 'http' # http | taskqueue | cron | mail | rdc
Url_type2 = 'access' # only when type = http access | debug | error | warning | notice | resources
Secret_key = 'xxxxx'

Generate request address

For more information about the request address generation method, see the requirements on the official website:

1. sort parameters
2. generate a request string, remove &
3. add access_key
4. request the string for md5 to form the sign
5. add the sign to the request string.

The specific implementation code is as follows:

The code is as follows:


Params = dict ()
Params ['AC'] = 'log'
Params ['appname'] = appname
Params ['from'] = from_date
Params ['to'] = to_date
Params ['type'] = url_type

If url_type = 'http ':
Params ['type2'] = url_type2

Params = collections. OrderedDict (sorted (params. items ()))

Request =''
For k, v in params. iteritems ():
Request + = k + '=' + v + '&'

Sign = request. replace ('&','')
Sign + = secret_key

Md5 = hashlib. md5 ()
Md5.update (sign)
Sign = md5.hexdigest ()

Request = api_url + request + 'sign = '+ sign

If response ['errno']! = 0:
Print '[!] '+ Response ['errmsg']
Exit ()

Print '[#] request success'

Download log files

Saepack every day's log files into a tar.gzformat. save the files as soon as they are saved, and the file name is named as "date .tar.gz ".

The code is as follows:


Log_files = list ()

For down_url in response ['data']:
File_name = re. compile (r' \ d {4}-\ d {2}-\ d {2} '). findall (down_url) [0] + '.tar.gz'
Log_files.append (file_name)
Data = urllib2.urlopen (down_url). read ()
With open (file_name, "wb") as file:
File. write (data)

Print '[#] you got % d log files' % len (log_files)

Merge files

Merge files by using the trafile library to decompress each file, and then append the file content to access_log.

The code is as follows:


# Compress these files to access_log
Access_log = open ('Access _ log', 'w ');

For log_file in log_files:
Tar = tarfile. open (log_file)
Log_name = tar. getnames () [0]
Tar. extract (log_name)
# Save to access_log
Data = open (log_name). read ()
Access_log.write (data)
OS. remove (log_name)

Print '[#] all file has writen to access_log'
