HUE API JavaScript HTTP PUT請求返回“ net :: ERR_EMPTY_RESPONSE”

Question

1. GET請求工作正常。

2. 來自API調試工具的PUT請求可以正常工作。

3. PUT和POST，無論使用的是數據還是API URL，都將返回以下錯誤：

   例：

   選項http：//xxx.xxx.xx/api/AuthorizedUsername/APIRequest/lights/light/1/狀態網：: ERR_EMPTY_RESPONSE

它返回一個空響應。

我相關的Angular JS代碼：

var bridgeIp = "http://xxx.xxx.x.x";
var username = "authenticatedUsername";
var lightData = {"on": true};

$http.put(bridgeIp+"/api/"+username+"/lights/5/state", lightData)
.then(function success(response) {
          console.log(response.data);
     }, function error(e){
          console.log(e);
     });

我也嘗試過使用JQuery的Ajax函數並收到相同的問題。

我使用提琴手比較了請求，但這導致了CORS錯誤。 因此，我隨后將請求與Charles進行了比較。 結果如下：

通過API調試工具：

Answer 1

這對我有用：

 var xmlhttp = new XMLHttpRequest(); xmlhttp.open("PUT", 'http://<local address>/api/<username>/groups/1/action'); xmlhttp.send('{"on":true, "hue": 16000, "bri": 254'}'); 

Answer 2

您的JavaScript輸出將Method顯示為OPTIONS。 如果那是發布頂部列出的OPTIONS，那么這看起來是錯誤的，因為它說... APIRequest / lights / light / 1 / state，但可能應該是... APIRequest / lights / 1 / state
