XMLHttpRequest 请求 URI 太大 (414)

发布于 2024-09-05 21:03:52 字数 868 浏览 3 评论 0原文

好吧，我希望最终一切都会顺利。但当然不是。新问题是以下消息：

Request-URI Too Large
请求的 URL 长度超过该服务器的容量限制。

我担心的是我必须找到另一种传输数据的方法或者是否有可能的解决方案？

XHR函数代码：

function makeXHR(recordData)
{
if (window.XMLHttpRequest)
 {
 xmlhttp=new XMLHttpRequest();

 }
 else
 {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
 }

 var rowData = "?q=" + recordData;

 xmlhttp.open("POST", "insertRowData.php"+rowData, true);
 xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded"); 
 xmlhttp.setRequestHeader("Content-Length",rowData.length); 
 xmlhttp.setRequestHeader("Connection", "close");

 xmlhttp.onreadystatechange = function() 
 {
  if(xmlhttp.readyState == 4 && xmlhttp.status == 200) 
  {
   alert("Records were saved successfully!");
  }
 }

 xmlhttp.send(null);

}

Well I hoped everything would work fine finally. But of course it doesn't. The new problem is the following message:

Request-URI Too Large
The requested URL's length exceeds the
capacity limit for this server.

My fear is that I have to find another method of transmitting the data or is a solution possible?

Code of XHR function:

function makeXHR(recordData)
{
if (window.XMLHttpRequest)
 {
 xmlhttp=new XMLHttpRequest();

 }
 else
 {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
 }

 var rowData = "?q=" + recordData;

 xmlhttp.open("POST", "insertRowData.php"+rowData, true);
 xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded"); 
 xmlhttp.setRequestHeader("Content-Length",rowData.length); 
 xmlhttp.setRequestHeader("Connection", "close");

 xmlhttp.onreadystatechange = function() 
 {
  if(xmlhttp.readyState == 4 && xmlhttp.status == 200) 
  {
   alert("Records were saved successfully!");
  }
 }

 xmlhttp.send(null);

}

您应该通过 send 方法在请求正文中 POST rowData。因此，不要发布到 "insertRowData.php" + rowData，而是发布到 "insertRowData.php" 并将 rowData 中的数据传递给 <代码>发送。

我怀疑您的 rowData 是带有问号的查询字符串。如果是这种情况，那么消息正文只是 rowData 而没有前面的问号。

编辑：这样的东西应该有效：

var body = "q=" + encodeURIComponent(recordData);
xmlhttp.open("POST", "insertRowData.php", true);
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlhttp.onreadystatechange = // ...
xmlhttp.send(body);

You should POST rowData in the request body via the send method. So, instead of posting to "insertRowData.php" + rowData, POST to "insertRowData.php" and pass the data in rowData to send.

I suspect that your rowData is a query string with the question mark. If that is the case, then the message body is simply rowData without the prepended question mark.

EDIT: Something like this should work:

var body = "q=" + encodeURIComponent(recordData);
xmlhttp.open("POST", "insertRowData.php", true);
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlhttp.onreadystatechange = // ...
xmlhttp.send(body);
