我使用SIPSimpleClient SDK構建一個簡單的腳本，可以創建與其他一些SIP用戶的SIP會話。我開始複製並粘貼Hello World示例here到python腳本並執行它。我收到以下錯誤sipsimpleclient SDK session.connect（）「類型錯誤：__init __（）恰恰1參數（給定2）」
Placing call to sip:[email protected], press Enter to quit the program

對腳本放棄後，我建立了我自己的腳本從零開始基礎上，Hello World示例，並使用提供here的文檔。首先，創建一個TestClass對象（一個SIPApplication類的子類）。 TestClass中的init方法調用self.start（FileStorage（'config'）），此時SIPApplicationDidStart messgae會觸發我的_NH_SIPApplicationDidStart方法。到目前爲止，這一切都很好，而且這種方法的所有方面都按預期工作。當被調用者的DNSLookup成功時，它發送一個DNSLookupDidSucceed消息，該消息觸發_NH_DNSLookupDidSucceed方法。在這種方法中，我創建了一個新的會話對象（self.session = Session（account）），這似乎工作正常（我可以打印此對象的屬性此時）。這個問題似乎在self.session.connect（self.callee，self.routes，[AudioStream（account）]）行中。這就是我在Hello World例子中得到相同錯誤的地方。您可以在文檔的第61頁上看到此連接方法及其參數。

我只是把XS放在哪裏，程序輸出我的賬戶名。我只是不明白這裏發生了什麼。有人知道他們爲什麼會發佈一個引發錯誤的示例程序嗎？或者這只是我的一個問題？如果您可以告訴我@run_in_green_thread行用於什麼或爲什麼發送DNSLookupDidSucceed消息兩次，獎勵點。 順便說一句，我通過SSH使用Ubuntu Trusty Tahr服務器。我正在爲一家公司這樣做，所以他們建立了環境。我假設所有的依賴都安裝正確，因爲我可以使用命令行中的sipclients（如sip-message和sip-audio-session）。我也瀏覽了這些sipclients的代碼（不是全部），他們似乎使用了同樣的session.connect（）方法，而沒有這個問題。除官方文檔外，這個SDK似乎沒有多大幫助。 在此先感謝，並且這裏是我的腳本的代碼。
