【问题描述】：

为了创建获取请求，我创建了一个 Python 脚本。为了为此请求创建 URL，我编写了以下代码：

today = str(datetime.date.today())
start = str(datetime.date.today()- datetime.timedelta (days=30))

report = ["Shifts",
          "ShiftStops",
          "ShiftStopDetailsByProcessDate",
          "TimeRegistrations",
          "ShiftsByProcessDate",
          "ShiftStopsByProcessDate",
          ]

for x in report:
    url_data = "https://URL"+ report + "?from=" + start + "&until=" + today
data = requests.get(url_data, headers = {'Host': 'services.URL.com', 'Authorization': 'Bearer ' + acces_token})```

But the error I get is: TypeError: can only concatenate str (not "list") to str

What can I do to solve this and create 6 unique url's?

p.s. I have added the word URL to the URL's in order to anonymize my post.

"https://URL"+ report 应该是"https://URL"+ x 并修复缩进

【解决方案1】：

您出错的地方在以下行中：

url_data = "https://URL"+ report + "?from=" + start + "&until=" + today

具体来说，您使用 report，这是整个列表。您要做的是改用x，即字符串在列表。

您还需要缩进下一行，所以它应该是：

for x in report:
    url_data = "https://URL"+ x + "?from=" + start + "&until=" + today
    data = requests.get(url_data, headers = {'Host': 'services.URL.com', 'Authorization': 'Bearer ' + acces_token})
