Question

我爱Unirest，我确实喜欢...

不幸的是，它似乎不是很安全的线程。

我试图并行处理我的请求：

runBlocking {
    for (a in 0..9) async{
        for (b in 0..9) async{
            for (c in 0..9) async{
                if (!found) Unirest.post(targetURL)
                    .body(String.format(requestTemplate, a, b, c))
                    .asStringAsync(object : Callback<String> {...})
            }
        }
    }
}

我所获得的只是

在没有async的情况下，代码可以正常运行，因此我将错误归咎于并发访问非并发访问的资源。（如果我对此有误，请祈祷。）

是否存在轻量级的客户端框架却允许这种并行化？

是否有一个轻量级的REST客户端框架可以并行构建请求？
