【报Bug】request开启enableChunked丢包

示例代码：

this.controller = uni.request({
url,
method: "POST",
header: httpHeaders,
data: params,
responseType: "arraybuffer",
enableChunked: true,
timeout: 60000,
dataType: 'text',
success() { console.log("流式请求完成"); },
fail(err) { console.error("连接错误:", err); }
});
// eslint-disable-next-line @typescript-eslint/ban-ts-comment
// @ts-ignore
let i = 0
this.controller?.onChunkReceived(chunk => {
const decoder = new TextDecoder('utf-8', { fatal: false });
const text = decoder.decode(new Uint8Array(chunk.data), { stream: true });
const data = parser.feed(text) as EventSourceMessage;
i++
console.log("收到数据块:", i, data);
if (data) {
this.callback(data);
}
});

event:end
data:{"content":"done"}

收到数据块: 1 {event: 'start', data: '{"content":"正在思考..."}'}
vconsole.min.js:10 收到数据块: 2 {event: 'commodity', data: '{"content":"{\"code\":200,\"data\":{\"total\":4,\"…xNTUiXQ==\"},\"extData\":null,\"msg\":\"查询成功\"}"}'}

操作步骤：

执行示例代码,查看onChunkReceived回调和http响应

预期结果：

数据全部回调

实际结果：

只回调部分数据
