问题
Calling one of our in-house web services seems to be giving the following error:
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)
From what I've seen elsewhere, this is being pointed to as a server issue, but we're not seeing this problem when the WS is being called in browser or in IOS. I've used both OkHTTP and a manual HTTPUrlConnection implementation and it hasn't seemed to make any difference. Does anyone have any ideas?
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();
回答1:
Please try the potential solutions (in my opinion) below:
1- Try to use retryOnConnectionFailure(true)
as below:
OkHttpClient client = new OkHttpClient.Builder()
.retryOnConnectionFailure(true)
.build();
2- Try to add: request.addHeader("Connection","close")
(most cases this is the solution, respecting to Kartik's answer.)
Request request = new Request.Builder()
.addHeader("Authorization", "Bearer " + apiToken)
.addHeader("content-type", "application/json")
.addHeader("Connection","close")
.url(uri)
.build();
3- Please increase the response time of the server (set it as high as possible) and try again.

回答2:
This error TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
is related to server. A possible reason could be, the server is shut down.
回答3:
Both the client and server needs to close the connection once they are finished.
In your OkHttp request builder, add this line: .header("Connection", "close")
.
Also check the network tab of your browser inspector to see which headers the browser is sending. Match those headers in your code and it should work.
