javascript - 发送 qx.io.request.Xhr 请求，请求中包含数组

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？

Answer 1

您必须将方法设置为 POST

request.setMethod('POST'); 

在调用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();
