`ValueError：需要多個值才能在Python OAuthLib中解壓縮？

Question

我使用OAuthLib讓訪問者通過LinkedIn登錄我的網站。我現在想A股（更新）發佈到自己的個人資料（as described here），我嘗試使用下面的代碼來執行：

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，這讓我在第二行的錯誤，說ValueError: need more than 1 value to unpack（回溯在消息下面）。

有誰知道最新錯了嗎？歡迎所有提示！

有一個在flask_oauthlib.client模塊怪異的行爲，如果你調用​​方法沒有content_type參數，它url_encode的數據。由於你的data參數（xmlStr）是純字符串，你會得到異常。

底線，你的電話更改爲以下，一切都應該是好：

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