调用API获得下载地址
文档位置在这里
设置自己的应用和下载参数
请求中需要设置的变量如下
生成请求地址
请求地址生成方式可以看一下官网的要求：
1.将参数排序
2.生成请求字符串，去掉&
3.附加access_key
4.请求字符串求md5，形成sign
5.把sign增加到请求字符串中
具体实现代码如下
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'
下载日志文件
SAE将每天的日志文件都打包成tar.gz的格式，下载保存下来即可，文件名以日期.tar.gz命名
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)
合并文件
合并文件方式用trafile库解压缩每个文件，然后把文件内容附加到access_log下就可以了
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'
