【问题描述】：

我的 python 代码使用 REST API 从 Confluence 读取页面数据，然后使用该数据在 Confluence 中创建一个新页面。发布数据时，代码抛出以下错误：

 UnicodeEncodeError: 'ascii' codec can't encode character u'\xa0' in position 48108: ordinal not in range(128)

但是，它在 Postman 中运行良好。我的猜测是邮递员处理编码。我发现许多建议使用str.encode('utf-8') 和str.encode('ascii', 'ignore') 的答案，但没有一个对我有用。我也试过了：

   import sys
   reload(sys)
   sys.setdefaultencoding('utf-8')    

但徒劳无功。如果我使用其中任何一个进行编码，则在触发发布请求时会收到 500 内部错误。

这是我的 python 代码：get_template_data 获取汇合页面详细信息并在发布请求中使用它来创建新页面。

#5. Get the weekly status template page data
def get_template_data():
    url = 'https://confluence.abc.com/rest/api/content/11111111?expand=body.export_view'
    headers['content-type'] = "application/json"    
    r = requests.get(url, headers=headers)
    data = r.json()
    template_data=data['body']['export_view']['value']
    return template_data

#6. Using weekly status template page(5) & string(2), create (post) a new page in Confluence.
def create_weekly_status_page(title,template_data):
    post_data_prefix = """"type":"page","title":"%s", "ancestors":["id":222222], "space":"key":"TST","body":"storage":"value":"%s","representation":"storage""""

    #template_data1 = u' '.join(template_data).encode('utf-8')
    template_data = template_data.replace('"', '\\"')
    post_body_str = post_data_prefix % (title, template_data)

    url = 'https://confluence.abc.com/rest/api/content/'
    headers['content-type'] = "application/json"

    r = requests.post(url, headers=headers, data=post_body_str)
    print r.status_code
    r.raise_for_status()

def main():
    #5. Get the weekly status template page data
    template_data = get_template_data()
    #print "template_data:", template_data

    #6. Using weekly status template page(5) & string(2), create (post) a new page in Confluence.
    # The weekly status string (2) will serve as title of the page
    weekly_status_str = "Weekly Report (01/01/17 - 01/05/17)
    create_weekly_status_page(weekly_status_str,template_data)

罪魁祸首是r = requests.post(url, headers=headers, data=post_body_str)。所以post_body_str 中的数据很可能与此有关。

以下是stracktrace：

    v = self._sslobj.write(data)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xa0' in position 52926: ordinal not in range(128)

另外，我在获取模板数据时使用body.export_view，因为该页面包含宏，我不希望复制宏，而是复制宏的结果。因此使用body.export_view。

我对 Python 很陌生。并编写此代码以自动化一些东西并同时学习 Python。将不胜感激一些帮助/指针。

Python 版本：2.7.10

【参考方案1】：

在这两行的帮助下，我终于设法完成了这项工作：

template_data = template_data.encode('ascii', 'ignore') 和template_data = template_data.replace('\n', '\\n')

第一行修复UnicodeEncodeError，而第二行修复500 Internal Error。

【讨论】：

嗨 Sandeep，你能解释一下你在哪里添加了这两行吗？由于您提到罪魁祸首是您提出的获取请求。我面临着完全相同的错误:(

【参考方案2】：

response = requests.get(url = url, headers = headers)

mydata = response.text.encode('ascii', 'ignore')

在浪费了一天的时间后，上面为我解决了这个问题:( :(
