python - Pastebin api为python中的requests.post返回 "Bad API request, use POST request, not GET"？

Question

我正在尝试使用发送 post 请求的 requests.post 从 python 使用 patebin api，我的代码是

# importing the requests library
import requests

# defining the api-endpoint
API_ENDPOINT = "http://pastebin.com/api/api_post.php"

# your API key here
API_KEY = "my api key"

# your source code here
source_code = '''
print("Hello, world!")
a = 1
b = 2
print(a + b)
'''

# data to be sent to api
data = {'api_dev_key':API_KEY,
        'api_option':'paste',
        'api_paste_code':source_code,
        'api_paste_format':'python'}

# sending post request and saving response as response object
r = requests.post(url = API_ENDPOINT, data = data)

# extracting response text
pastebin_url = r.text
print("The pastebin URL is:%s"%pastebin_url)

文档中给出的 curl 发布请求适用于我的 api key ，我得到了粘贴 url。
但我收到 错误的 API 请求，使用 POST 请求，而不是 GET 上面python代码的输出是否有人有任何建议

正如@LeventeKovács 指出的那样，简单的解决方法是将 URL 中的请求类型从“http”更改为“https”。这就是为什么 Requests 库没有按照您当前的 URL 执行您想要/期望的操作...
您正在向 HTTPS 端点发出 HTTP 请求。这需要从 HTTP 重定向到 HTTPS。处理此重定向时，请求库将 POST 更改为 GET，代码如下:

# Second, if a POST is responded to with a 301, turn it into a GET.
# This bizarre behaviour is explained in Issue 1704.
if response.status_code == codes.moved and method == 'POST':
    method = 'GET'

这是与此代码相关的评论中提到的问题的链接:

https://github.com/psf/requests/issues/1704

该问题引用了 HTTP 规范的这一部分:

301 Moved Permanently If the 301 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued. Note: When automatically redirecting a POST request after receiving a 301 status code, some existing HTTP/1.0 user agents will erroneously change it into a GET request.

然后似乎继续通过说请求库应该做大多数/所有浏览器当前所做的事情来合理化代码的行为，即将 POST 更改为 GET 并在新地址重试。
