Question

根据documentation，requestData可以处理ArrayBuffer参数。但是当我尝试这个时：

var buf = new ArrayBuffer(16); 
var ar = new Uint8Array(buf); 
for(var i = 0; i < ar.length; i++) 
    ar[i] = i * 10; 
request = new qx.io.request.Xhr(); 
request.setUrl(url); 
request.setRequestData(buf); 
request.send();

我收到以下错误：

Error: params must be either string or object

我做错了什么？

您必须将方法设置为POST

request.setMethod('POST');

在致电request.send()之前。所以你的例子看起来像这样：

var buf = new ArrayBuffer(16); 
var ar = new Uint8Array(buf); 
for(var i = 0; i < ar.length; i++) {
    ar[i] = i * 10; 
}
request = new qx.io.request.Xhr().set({
    url: url,
    requestData: buf,
    method: 'POST'
}).send();

在请求中使用数组发送qx.io.request.Xhr请求
