php無法識別JSON發佈消息

Im正在努力通過XMLhttp發送請求發送JSON數據。數據是：php無法識別JSON發佈消息

"{"reqData":{"reqType":"post","reqName":"getCurrTemp","reqPayload":""}}"

JS代碼是：在PHP端有問題

 var reqData = { 
      reqType : "post", //isDateRequested : 1, 
      reqName : "getCurrTemp", 
      reqPayload : "" 
     }; 

     var dataToSend = {'reqData' : reqData }; 
     var jData = JSON.stringify(dataToSend); 
     alert(jData); 
     var oReq = new XMLHttpRequest(); 
      oReq.onload = function() { 
      data = JSON.parse(this.responseText); 

      }; 
      oReq.open("POST", "handleRequests.php", true); 
     oReq.send(jData);

IM，看起來像服務器無法識別JSON，甚至報文丟失......

我用wireshark嗅探流量：

POST /autHouse/handleRequests.php HTTP/1.1 
Host: 192.168.0.12 
Connection: keep-alive 
Content-Length: 70

string(70) "{"reqData":{"reqType":"post","reqName":"getCurrTemp","reqPayload":""}}"

這裏是php代碼：

$body = file_get_contents('php://input'); 
    error_log(var_dump($body)); 
    $reqData= json_decode($_POST['reqData'], true); 
    $reqType = $reqData["reqType"]; 
    $reqName = $reqData["reqName"];

和realted PHP錯誤日誌：

[Tue Jan 19 11:54:23 2016] [error] [client 192.168.0.121] , referer: http://192.168.0.12/autHouse/ah.html

能否請你告訴我，爲什麼PHP complians而IM發送正確的JSON數據？

試試這個'$ reqData = json_decode（$身體，真）; ' – RiggsFolly

沒有改變一件事... – JosiP

試試這個

var xmlhttp = new XMLHttpRequest(); 
xmlhttp.open("POST", "handleRequests.php", true); 
xmlhttp.setRequestHeader("Content-Type", "application/json;charset=UTF-8"); 
xmlhttp.send(jData);

仍然同樣reslut ... – JosiP

你已經錯過所得數組中的水平。

$body = file_get_contents('php://input'); 
error_log(var_dump($body)); 
$reqData= json_decode($_POST['reqData'], true); 
$reqType = $reqData['reqData']["reqType"]; 
$reqName = $reqData['reqData']["reqName"];

如果您更喜歡使用的數據正在傳遞的對象爲，而不是轉換對象數組，你可以做
