Question

我使用OAuthLib让访问者使用LinkedIn登录我的网站。我现在想要将共享（更新）发布到他们的个人资料（as described here），我尝试使用以下代码：

xmlStr = '<share><comment>This is a comment.</comment><content><title>This is the title</title><description>This is the description</description><submitted-url>http://www.isittuesday.co.uk</submitted-url><submitted-image-url>http://stunningplaces.net/wp-content/uploads/2014/05/11-Rio-de-Janeiro-Cochabana-Beach.-Photo-by-ballnkicka.com_.jpg</submitted-image-url></content><visibility><code>connections-only</code></visibility></share>'
r = linkedInApp.post('people/~/shares', data=xmlStr, headers={'content-type': 'application/xml'})

不幸的是，这让我在第二行遇到错误，说ValueError: need more than 1 value to unpack（在消息下方追溯）。

有人知道什么是错的吗？欢迎所有提示！

flask_oauthlib.client模块中存在奇怪的行为，如果您在没有request/get/post参数的情况下调用content_type方法，则url_encode是您的数据。由于您的data参数（xmlStr）是纯字符串，因此会出现异常。

底线，将您的通话更改为以下内容，一切正常：

r = linkedInApp.post('people/~/shares', data=xmlStr, content_type='application/xml')

`ValueError：在Python OAuthLib中需要多于1个值才能解压缩？
