调用我们的内部Web服务似乎会出现以下错误:

java.io.IOException: unexpected end of stream on Connection{webservicessandbox.xxx.com:443, proxy=DIRECT@ hostAddress=174.143.185.13 cipherSuite=TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA protocol=http/1.1} (recycle count=0)

从我在其他地方看到的,这被指向服务器问题,但是当在浏览器或IOS中调用WS时,我们没有看到这个问题.我已经使用了OkHTTP和手动HTTPUrlConnection实现,它似乎没有任何区别.有没有人有任何想法？

OKHttp:
            OkHttpClient client = new OkHttpClient();
            Request request = new Request.Builder()
                    .addHeader("Authorization", "Bearer " + apiToken)
                    .addHeader("content-type", "application/json")
                    .url(uri)
                    .build();
HTTPURLConnection:
            URL myURL = new URL(uri);
            HttpsURLConnection myConnection = (HttpsURLConnection) myURL.openConnection();
            myConnection.setConnectTimeout(TIMEOUT_MILLISEC);
            myConnection.setDoOutput(false);
            myConnection.setRequestMethod("GET");
            myConnection.setRequestProperty("Authorization", "Bearer " + apiToken);
            myConnection.setRequestProperty("content-type", "application/json");
            int respCode = myConnection.getResponseCode();

我得到了一些Scheme代码,并负责将代码转换为Perl.

(define (makecounter)
 (let ((x 0)) (lambda () (begin (set! x (+ x 1)) x))))

我知道这应该是一个闭包函数,但是我不能完全理解它应该做的事情.有任何想法吗？
