不久前,我在这里发帖寻求使用 API 从 Tumblr 博客下载数据的帮助。birryree ( https://stackoverflow.com/users/297696/birryree ) 非常友好地帮助我纠正了我的脚本并找出我哪里出错了,从那以后我一直在使用他的脚本没有问题(打印超过来自 Tumblr API 的 20 个帖子)。

这个脚本要求我每次都手动输入我要下载的博客名称。但是,我需要下载数百个博客,所以这导致我使用相同脚本的数百个版本并且非常耗时。我做了一些谷歌搜索,发现可以编写 Python 脚本,您可以在其中从命令行输入参数,然后它们将被一一处理(如果这是正确的术语)。

我尝试编写一个脚本,让我从命令提示符运行命令,然后下载我在命令提示符中要求的三个博客。(在这种情况下,“prettythingsicantafford.tumblr.com;theficrecfairy.tumblr.com;和 staff.tumblr.com)。

所以我试图运行的脚本是:

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

为了响应这个错误,我已经尝试修改我的脚本大约两周了,但我无法纠正我无疑非常明显的错误,并且非常感谢任何帮助或建议。

编辑以下 vishes_shell 的建议:

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: "

您尝试解决的问题client.posts(blog, ...)blog对象tuple,声明为:

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

您需要重构您的方法以分别浏览每个博客。

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

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

blog = sys.argv
...
