解析 XML 時 JSON 中出現意外字符串

Question

我正在嘗試從 Oracle 數據庫中讀取基本上是 XML 的 clob 並填充到 AngularJS UI 網格中。 我對 JSON 做同樣的事情，並且工作得很好。

JSON 來自后端的響應

每當我嘗試讀取值時，它都會拋出異常

JSON 中的意外字符串 position 372 在 JSON.parse ( <anonymous> )

下面是 AJAX 響應代碼：

$http.get(url).then(function(response) {
    if(response.data.events == null || response.data.events == undefined ||
            response.data.events == "undefined"){
        $("#loader1").hide();
        $scope.close = true;
        $scope.responseMessage = "";
        $scope.gridOptions1.data.length=0;
        $scope.errorMessage = "Order not found!!!!";
    }else{
        console.log("1");
        $("#loader1").hide();
        var responseNew = JSON.stringify(response.data.events);
        $scope.gridOptions1.data = responseNew;
        $scope.mySelectedRows = $scope.gridApi.selection.getSelectedRows();
        $scope.close = true;
        $scope.errorMessage = "";
        $scope.responseMessage = "Order details fetched successfully";
    }
}, function(response) {
    $("#loader1").hide();
    $scope.close = true;
    $scope.responseMessage = "";
    $scope.gridOptions.data.length=0;
    $scope.gridOptions1.data.length=0;
});

Answer 1

這里有一個額外的雙引號：

Parse error on line 1:
...\"EOMS_0178_TEST\">""    <name firstName...
-----------------------^
Expecting 'EOF', '}', ':', ',', ']', got 'STRING'

Answer 2

使用 JSON.parse 而不是 JSON.stringify。 您從后端（上面提到的那個）得到的響應已經是一個字符串化的 JSON，您必須將其解析出來才能讀取值。

Answer 3

上述問題是在 DB 中存儲 xml 時出現的。 因為新元素之間有空格。 它正在考慮將其作為一個字符串，並在 JSON 中附加雙引號。
