Question

我收到以下错误：

"Data at the root level is invalid. Line 1, position 1."

以下是WEB APIpartial代码：

//POST api/RunningValue_Import
public object PostRunningValue(HttpRequestMessage xml)
{
    try
    {
        #region Retrieve XML string and Create XDocument

        //the method below generates the same error:
        //string tempXmlString = xml.Content.ReadAsStringAsync().Result;
        //TextReader tr = new StringReader(tempXmlString);
        //XDocument doc = XDocument.Load(tr);

        XDocument doc = XDocument.Load(xml.Content.ReadAsStreamAsync().Result); //<=== ERROR!

        #endregion

jQuery的：

var inputText = inputText.replace(/ /g, ''); //eliminate spaces
inputText = inputText.replace(/\"/g, '\\"'); //escape double quotes

$.ajax({
    type: "POST",
    url: reqUrl,
    data: inputText,
    datatype: "text",
    contentType: "text/xml"
});

inputText变量内容：

inputText = "\\\"<?xmlversion=\\\"1.0\\\"encoding=\\\"utf-8\\\"standalone=\\\"yes\\\"?>\n<server>\n<networkAdapters>\n<networkAdapterid=\\\"3d9c0d9d-d353-4d78-b034-b29f2dd824a0\\\">\n</networkAdapter>\n</networkAdapter>\n</server>\\\""

传递原始XMl字符串：

"<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<server>
  <networkAdapters>
    <networkAdapter id="3d9c0d9d-d353-4d78-b034-b29f2dd824a0">
    </networkAdapter>
  </networkAdapter>
</server>"

删除所有空格会导致问题。如果我取消引号和斜杠，你会发现它不是有效的XML：

<?xmlversion="1.0"encoding="utf-8"standalone="yes"?><server><networkAdapters><networkAdapterid="3d9c0d9d-d353-4d78-b034-b29f2dd824a0"></networkAdapter></networkAdapter></server>

如果您尝试将其格式化以便于阅读，它看起来像这样：

<!-- This declaration is invalid without spacing -->
<?xmlversion="1.0"encoding="utf-8"standalone="yes"?>
<server>
    <networkAdapters>
        <!-- This should read "networkAdapter id" not "networkAdapterid" -->
        <networkAdapterid="3d9c0d9d-d353-4d78-b034-b29f2dd824a0"></networkAdapter>
    <!-- This should be a closing bracket for networkAdapters, not networkAdapter -->
    </networkAdapter>
</server>

XDocument.Load生成错误：＆＃34;根级别的数据无效。第1行，第1位。＆＃34;
