使用Tumblr使用多个“博客名”/command行参数

Question

不久前，我在这里发布了使用API从Tumblr博客下载数据的帮助。birryree (https://stackoverflow.com/users/297696/birryree)很好地帮助我纠正了我的脚本，找出了我的错误所在，而且我一直在使用他的脚本，从那时起我就没有问题了(Print more than 20 posts from Tumblr API)。

这个脚本要求我每次都要手动输入我想下载的博客名。但是，我需要下载数百个博客，所以这导致我使用了数百个相同脚本的版本，而且非常耗时。我做了一些搜索，发现编写Python脚本是可能的，您可以从命令行输入参数，然后逐个处理它们(如果这是正确的术语)。

我试图编写一个脚本，它允许我从命令提示符中运行一个命令，然后在命令提示符中下载我所要求的三个博客。(在本例中，"prettythingsicantafford.tumblr.com；theficrecfairy.tumblr.com；和staff.tumblr.com“)。

所以我想要运行的脚本是：

import pytumblr
import sys


def get_all_posts(client, blog):
offset = 0
while True:
    response = client.posts(blog, limit=20, offset=offset, reblog_info=True, notes_info=True)

    # Get the 'posts' field of the response        
    posts = response['posts']

    if not posts: return

    for post in posts:
        yield post

    # move to the next offset
    offset += 20



client = pytumblr.TumblrRestClient('SECRET')
blog = (sys.argv[1], sys.argv[2], sys.argv[3])


# use our function
with open('{}-posts.txt'.format(blog), 'w') as out_file:
for post in get_all_posts(client, blog):
    print >>out_file, post

我正在从命令提示符运行以下命令

tumblr_test2.py theficrecfairy prettythingsicantafford staff

但是，我收到以下错误消息：

Traceback (most recent call last):
File "C:\Users\izzy\test\tumblr_test2.py", line 29, in <module>
for post in get_all_posts(client, blog):
File "C:\Users\izzy\test\tumblr_test2.py", line 8, in get_all_posts
response = client.posts(blog, limit=20, offset=offset, reblog_info=True, notes_info=True)
File "C:\Python27\lib\site-packages\pytumblr\helpers.py", line 46, in add_dot_tumblr
args[1] += ".tumblr.com"
TypeError: can only concatenate tuple (not "str") to tuple

为了应对这一错误，我已经尝试修改我的脚本大约有两个星期了，但我一直无法纠正我明显的错误，我将非常感谢任何帮助或建议。

编辑以下vishes_shell建议：

我现在正在使用以下脚本：

import pytumblr
import sys


def get_all_posts(client, blogs):
for blog in blogs:
    offset = 0
while True:
    response = client.posts(blog, limit=20, offset=offset, reblog_info=True, notes_info=True, filter='raw')

    # Get the 'posts' field of the response        
    posts = response['posts']

    if not posts: return

    for post in posts:
        yield post

    # move to the next offset
    offset += 20


client = pytumblr.TumblrRestClient('SECRET')
blog = sys.argv

# use our function
with open('{}-postsredux.txt'.format(blog), 'w') as out_file:
for post in get_all_posts(client, blog):
    print >>out_file, post

但是，我现在收到以下错误消息：

Traceback (most recent call last):
File "C:\Users\izzy\test\tumblr_test2.py", line 27, in <module>
with open('{}-postsredux.txt'.format(blog), 'w') as out_file:
IOError: [Errno 22] invalid mode ('w') or filename: " 
['C:\\\\Users\\\\izzy\\\\test\\\\tumblr_test2.py',

当client.posts(blog, ...)是tuple对象时，您试图进行tuple处理的问题，声明为：

blog = (sys.argv[1], sys.argv[2], sys.argv[3])

您需要重构您的方法，以单独浏览每个博客。

def get_all_posts(client, blogs):
    for blog in blogs:
        offset = 0
        ...

        while True:
            response = client.posts(blog, ...)
        ...
    ...

blog = sys.argv
...
