Question

我正在使用一个抽搐的irc bot，而我想要的其中一个组件是机器人能够在关闭时将引号保存到pastebin粘贴，然后在启动时检索相同的引号。

我已经开始使用保存部分了，并且遇到了一个路障，我似乎无法获得有效的帖子，而且我无法找到方法。

#!/usr/bin/env python3

import urllib.parse
import urllib.request

# --------------------------------------------- Pastebin Requisites --------------------------------------------------

pastebin_key = 'my pastebin key'  # developer api key, required. GET: http://pastebin.com/api
pastebin_password = 'password'  # password for pastebin_username
pastebin_postexp = 'N'  # N = never expire
pastebin_private = 0  # 0 = Public 1 = unlisted 2 = Private
pastebin_url = 'http://pastebin.com/api/api_post.php'
pastebin_username = 'username'  # user corresponding with key


# --------------------------------------------- Value clean up --------------------------------------------------

pastebin_password = urllib.parse.quote(pastebin_password, safe='/')
pastebin_username = urllib.parse.quote(pastebin_username, safe='/')

# --------------------------------------------- Pastebin Functions --------------------------------------------------

def post(title, content):  # used for posting a new paste
    pastebin_vars = {'api_option': 'paste', 'api_user_key':     pastebin_username, 'api_paste_private': pastebin_private,
                 'api_paste_name': title, 'api_paste_expire_date': pastebin_postexp,  'api_dev_key': pastebin_key,
                 'api_user_password': pastebin_password, 'api_paste_code': content}
    try:
        str_to_paste = ', '.join("{!s}={!r}".format(key, val) for (key, val) in pastebin_vars.items())  # dict to str :D
        str_to_paste = str_to_paste.replace(":", "")  # remove :
        str_to_paste = str_to_paste.replace("'", "")  # remove '
        str_to_paste = str_to_paste.replace(")", "")  # remove )
        str_to_paste = str_to_paste.replace(", ", "&")  # replace dividers with &
        urllib.request.urlopen(pastebin_url, urllib.parse.urlencode(pastebin_vars)).read()
        print('did that work?')
    except:
        print("post submit failed :(")
        print(pastebin_url + "?" + str_to_paste)  # print the output for test

 post("test", "stuff")

我愿意导入更多的图书馆和内容，在我连续工作两天之后不确定我做错了什么：S

Answer 1

import urllib.parse
import urllib.request

PASTEBIN_KEY = 'xxx'
PASTEBIN_URL = 'https://pastebin.com/api/api_post.php'
PASTEBIN_LOGIN_URL = 'https://pastebin.com/api/api_login.php'
PASTEBIN_LOGIN = 'my_login_name'
PASTEBIN_PWD = 'yyy'

def pastebin_post(title, content):
    login_params = dict(
        api_dev_key=PASTEBIN_KEY,
        api_user_name=PASTEBIN_LOGIN,
        api_user_password=PASTEBIN_PWD
    )

    data = urllib.parse.urlencode(login_params).encode("utf-8")
    req = urllib.request.Request(PASTEBIN_LOGIN_URL, data)

    with urllib.request.urlopen(req) as response:
        pastebin_vars = dict(
            api_option='paste',
            api_dev_key=PASTEBIN_KEY,
            api_user_key=response.read(),
            api_paste_name=title,
            api_paste_code=content,
            api_paste_private=2,
        )
        return urllib.request.urlopen(PASTEBIN_URL, urllib.parse.urlencode(pastebin_vars).encode('utf8')).read()

rv = pastebin_post("This is my title", "These are the contents I'm posting")
print(rv)

结合上面两个不同的答案给了我这个可行的解决方案。

Answer 2

到目前为止，我还不了解pastebin。我读了他们的api并且第一次尝试了它，它工作得非常好。

这就是我的所作所为：

我已登录以获取api_user_key。
包含在帖子中以及api_dev_key。
检查了网站，帖子就在那里。

以下是代码：

import urllib.parse
import urllib.request


def post(url, params):
    data = urllib.parse.urlencode(login_params).encode("utf-8")
    req = urllib.request.Request(login_url, data)
    with urllib.request.urlopen(req) as response:
       return response.read()


# Logging in to fetch api_user_key
login_url = "http://pastebin.com/api/api_login.php"
login_params = {"api_dev_key": "<the dev key they gave you",
                "api_user_name": "<username goes here>",
                "api_user_password": "<password goes here>"}
api_user_key = post(login_url, login_params)


# Posting some random text
post_url = "http://pastebin.com/api/api_post.php"
post_params = {"api_dev_key": "<the dev key they gave you",
               "api_option": "paste",
               "api_paste_code": "<head>Testing</head>",
               "api_paste_private": "0",
               "api_paste_name": "testing.html",
               "api_paste_expire_date": "10M",
               "api_paste_format": "html5",
               "api_user_key": api_user_key}
response = post(post_url, post_params)

发布内容只需要前三个参数，其余参数是可选的。

首先，您的except / except块会丢失实际错误。你几乎不应该使用＆＃34;裸＆＃34; try子句没有捕获或重新提升原始异常。有关完整说明，请参阅this article。

删除except / Traceback (most recent call last): File "<stdin>", line 1, in <module> File "paste.py", line 42, in post urllib.request.urlopen(pastebin_url, urllib.parse.urlencode(pastebin_vars)).read() File "/usr/lib/python3.4/urllib/request.py", line 161, in urlopen return opener.open(url, data, timeout) File "/usr/lib/python3.4/urllib/request.py", line 461, in open req = meth(req) File "/usr/lib/python3.4/urllib/request.py", line 1112, in do_request_ raise TypeError(msg) TypeError: POST data should be bytes or an iterable of bytes. It cannot be of type str.后，您会看到基本错误：

urllib.request.urlopen(pastebin_url, urllib.parse.urlencode(pastebin_vars)).read()

这意味着您尝试将unicode字符串传递给期望字节的函数。当您执行I / O（如在磁盘上读取/写入文件，或通过HTTP发送/接收数据）时，通常需要将任何unicode字符串编码为字节。有关unicode与字节以及何时需要编码和解码的详细说明，请参阅this presentation。

接下来，这一行：

str_to_paste

丢弃了响应，因此您无法知道API调用的结果。将其分配给变量或从函数返回它，以便您可以检查该值。它将是粘贴的URL，或来自API的错误消息。

接下来，我认为您的代码向API发送了许多不必要的参数，并且您的import urllib.parse import urllib.request PASTEBIN_KEY = 'my-api-key' # developer api key, required. GET: http://pastebin.com/api PASTEBIN_URL = 'http://pastebin.com/api/api_post.php' def post(title, content): # used for posting a new paste pastebin_vars = dict( api_option='paste', api_dev_key=PASTEBIN_KEY, api_paste_name=title, api_paste_code=content, ) return urllib.request.urlopen(PASTEBIN_URL, urllib.parse.urlencode(pastebin_vars).encode('utf8')).read()语句并不是必需的。

我能够使用以下更简单的代码进行粘贴：

>>> post("test", "hello\nworld.")
b'http://pastebin.com/v8jCkHDB'

这里正在使用：
