Java 是否有一个轻量级的REST客户端框架允许并行构造请求？

我爱你，我真的爱你

不幸的是，它似乎不是非常线程安全的

我尝试将我的请求并行化：

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> {...})
            }
        }
    }
}

代码在没有

async

s的情况下运行良好，因此我将把错误归咎于对不打算并发访问的资源的并发访问。（如果我错了，请告诉我。）

是否有轻量级的客户端框架允许这种并行化？

您研究过以下内容吗<代码>Unirest.setAsyncHttpClient（asyncHttpClient）和

Unirest.setConcurrency（int-maxTotal，int-maxPerRoute）

（其中

asyncHttpClient

是

HttpAsyncClient

）您似乎也可以使用它：

Unirest.post（…）.someMethod（…）.asJsonAsync（新回调（）{//匿名类}）你有没有研究过以下内容<代码>Unirest.setAsyncHttpClient（asyncHttpClient）
