[英]Network request to TV works from any device but Raspberry Pi
我正在嘗試通過網絡控制我的松下電視。 當我將它轉移到 Raspberry 時，我的所有代碼（節點）都在筆記本電腦上運行。 出於某種原因，它從那里不起作用。 （控制我的天龍接收器的類似項目效果很好。）
“不工作”是指可以訪問電視，但返回 403 錯誤。 當電視關閉時，它無法訪問。 於是樹莓派對着電視呼喚。
我嘗試了許多不同的方法，最終我正在處理 curl 請求。 它適用於任何地方，但不適用於 Raspberry：
curl 'http://192.168.178.142:55000/nrc/control_0' \
-H 'content-type: text/xml; charset="utf-8"' \
-H 'user-agent: net.thlabs.nodecontrol' \
-H 'soapaction: "urn:panasonic-com:service:p00NetworkControl:1#X_SendKey"' \
--data-binary '<?xml version="1.0" encoding="utf-8"?><s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><s:Body><u:X_SendKey xmlns:u="urn:panasonic-com:service:p00NetworkControl:1"><X_KeyEvent>NRC_MUTE-ONOFF</X_KeyEvent></u:X_SendKey></s:Body></s:Envelope>' \
--compressed
如果我通過任何其他設備（例如我的筆記本電腦）進行代理，它確實可以在 Raspberry上工作。 但是，這是行不通的，當我從代理通過筆記本電腦樹莓。
試了兩天了，有人知道嗎？
編輯：我進一步減少了卷曲：沒有用戶代理、內容類型和壓縮，這仍然適用於任何筆記本電腦（運行 Windows，也嘗試過 WSL shell），但在我的樹莓（1+3，Rasbian 和 ArchLinux）上，我收到 403 。 當我另外省略soapaction時，我到處都收到錯誤400。
curl 'http://192.168.178.142:55000/nrc/control_0' \
-H 'soapaction: "urn:panasonic-com:service:p00NetworkControl:1#X_SendKey"' \
