Question

我试图将名称模块与temp-mail.org（https://github.com/saippuakauppias/temp-mail）的包装一起用于涉及创建临时电子邮件地址的项目的一部分。我的代码如下所示，除非n大于2，否则工作正常。

import names
from random import randint
from tempmail import TempMail

n = input("Please enter number of email addresses: ")
i = 0
while i < n:
    first = names.get_first_name()
    second = names.get_last_name()
    tm = TempMail(login= first + "." + second + str(randint(1,99)))
    email = tm.get_email_address()
    print email
    i = i+1

如果n大于2，则循环将执行两次，然后我收到以下错误：

>>> runfile('/root/voter.py', wdir='/root')
Please enter number of email addresses: 3

    return self.scan_once(s, idx=_w(s, idx).end())
simplejson.scanner.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

我知道这是一个远景，因为tempmail模块并没有被广泛使用，但是我希望我在其他地方犯了一个简单的错误，有人可以提供帮助吗？感谢

好的，所以我查看了你的问题。

软件包temp-mail似乎向您调用TempMail()的每个时间提出temp-mail.ru 请求，以获取可用域列表。

您遇到了API的rate limiting（简而言之，您在太短的时间内调用了API太多次）

我在包中添加了一些调试以查看发生了什么。我创建了一个virtualenv来测试您的代码。这使我安装的模块（temp-mail和names仅在项目本地而不是全局安装在系统上）并查看堆栈跟踪。调用json部分的行是domains = req.json()，位于/home/arch/tmp-tempmail/env/lib/python2.7/site-packages/tempmail.py。

然后我编辑了文件以添加一些打印件（您必须首先了解request模块的一些概念）：

url = 'http://{0}/request/domains/format/json/'.format( self.api_domain) req = requests.get(url) print req print req.text domains = req.json()

输出结果为：

Please enter number of email addresses: 3 <Response [200]> ["@stexsy.com"] Larry.Gerald20@stexsy.com <Response [200]> ["@stexsy.com"] Darlene.Bullock32@stexsy.com <Response [429]> Traceback (most recent call last): File "main.py", line 29, in <module> email = tm.get_email_address() File "/home/arch/tmp-tempmail/env/lib/python2.7/site-packages/tempmail.py", line 68, in get_email_address available_domains = self.available_domains File "/home/arch/tmp-tempmail/env/lib/python2.7/site-packages/tempmail.py", line 38, in available_domains domains = req.json() File "/home/arch/tmp-tempmail/env/lib/python2.7/site-packages/requests/models.py", line 826, in json return complexjson.loads(self.text, **kwargs) File "/usr/lib64/python2.7/json/__init__.py", line 319, in loads return _default_decoder.decode(s) File "/usr/lib64/python2.7/json/decoder.py", line 339, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/usr/lib64/python2.7/json/decoder.py", line 357, in raw_decode raise JSONDecodeError("Expecting value", s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

你可以看到失败的响应是第三个，它有HTTP错误代码429，转换为“Too Many Requests”。 JSON解析器因为输入为空而崩溃。

另一方面，API的docs表示：

您可以在没有API通知的情况下生成绝对任何电子邮件地址

因此，如果您拥有该域，则无需向服务器发出请求以在服务器上接收邮件。

您还可以在循环内添加延迟。

import names from random import randint from tempmail import TempMail import time n = input("Please enter number of email addresses: ") i = 0 while i < n: first = names.get_first_name() second = names.get_last_name() tm = TempMail(login= first + "." + second + str(randint(1,99))) email = tm.get_email_address() print email time.sleep(1) i = i+1

Simplejson解码错误仅在执行两次迭代时发生
