在 Tumblr API 中使用多个 "blog name"/命令行参数

Question

不久前，我在此处发帖寻求使用 API 从 Tumblr 博客下载数据的帮助。蓝莓 (https://whosebug.com/users/297696/birryree) was kind enough to help me correct my script and figure out where I had been going wrong, and I have been using his script with no problems since ().

此脚本要求我每次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，因此这导致我使用同一个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，然后它们将被一个一个地处理（如果这是正确的术语）。

我尝试编写一个脚本，让我从命令提示符中运行命令，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）。

所以我尝试运行的脚本是：

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

我运行正在命令提示符下执行以下命令

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，但我一直无法纠正我无疑是非常明显的错误，非常感谢任何帮助或建议。

根据 vishes_shell 的建议进行编辑：

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', 
'prettythingsicantafford', 'theficrecfairy']-postsredux.txt"

Answer 1

当 blog 是 tuple 对象时，您尝试 client.posts(blog, ...) 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分别查看每个博客。

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

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

blog = sys.argv
...

在 Tumblr API 中使用多个 "blog name"/命令行参数
