我在我的Andr​​oid项目使用改造1.6.0，

I use Retrofit 1.6.0 on my Android project,

请求URL：

example/image/thumbs/filename/sample.png

我的界面是这样的：

public interface ImageService { @GET("/image/thumbs/filename/{filename}") @Streaming void getThumbs( @Path("filename") String filename, Callback<Response> callback ); }

HTTP请求是成功的，但也有一些错误发生

HTTP request was success, but there some error occur

D/Retrofit(27613): ---> HTTP GET example/image/thumbs/filename/sample.png D/Retrofit(27613): ---> END HTTP (no body) D/Retrofit(27613): <--- HTTP 200 example/image/thumbs/filename/sample.png (451ms) D/Retrofit(27613): : HTTP/1.1 200 OK D/Retrofit(27613): Connection: Keep-Alive D/Retrofit(27613): Content-Disposition: inline; filename="sample.png" D/Retrofit(27613): Content-Type: image/png; charset=binary D/Retrofit(27613): Date: Wed, 11 Jun 2014 06:02:31 GMT D/Retrofit(27613): Keep-Alive: timeout=5, max=100 D/Retrofit(27613): OkHttp-Received-Millis: 1402466577134 D/Retrofit(27613): OkHttp-Response-Source: NETWORK 200 D/Retrofit(27613): OkHttp-Sent-Millis: 1402466577027 D/Retrofit(27613): Server: Apache/2.2.22 (Ubuntu) D/Retrofit(27613): Transfer-Encoding: chunked D/Retrofit(27613): X-Powered-By: PHP/5.4.28-1+deb.sury~precise+1 D/Retrofit(27613): ---- ERROR example/image/thumbs/filename/sample.png D/Retrofit(27613): java.io.UnsupportedEncodingException: binary D/Retrofit(27613): at java.nio.charset.Charset.forNameUEE(Charset.java:322) D/Retrofit(27613): at java.lang.String.<init>(String.java:228) D/Retrofit(27613): at retrofit.RestAdapter.logAndReplaceResponse(RestAdapter.java:478) D/Retrofit(27613): at retrofit.RestAdapter.access$500(RestAdapter.java:109) D/Retrofit(27613): at retrofit.RestAdapter$RestHandler.invokeRequest(RestAdapter.java:333) D/Retrofit(27613): at retrofit.RestAdapter$RestHandler.access$100(RestAdapter.java:220) D/Retrofit(27613): at retrofit.RestAdapter$RestHandler$2.obtainResponse(RestAdapter.java:278) D/Retrofit(27613): at retrofit.CallbackRunnable.run(CallbackRunnable.java:42) D/Retrofit(27613): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1112) D/Retrofit(27613): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:587) D/Retrofit(27613): at retrofit.Platform$Android$2$1.run(Platform.java:142) D/Retrofit(27613): at java.lang.Thread.run(Thread.java:841) D/Retrofit(27613): Caused by: java.nio.charset.UnsupportedCharsetException: binary D/Retrofit(27613): at java.nio.charset.Charset.forName(Charset.java:309) D/Retrofit(27613): at java.nio.charset.Charset.forNameUEE(Charset.java:320) D/Retrofit(27613): ... 11 more D/Retrofit(27613): ---- END ERROR

我该如何解决这个问题？

How do I solve this problem?

推荐答案

这个问题是在响应Content-Type头包括一个虚假的字符集：

The issue is the content-type header on the response includes a bogus charset:

Content-Type: image/png; charset=binary

改造认为这并推断响应是文本，它可以记录。你应该将问题报告给服务器的管理员。

Retrofit sees this and infers that the response is text that it can log. You should report the problem to the server's administrator.

如果您在GitHub上改造的问题跟踪报告问题，我们或许可以从这个问题中恢复，而不是崩溃。

If you report the issue to Retrofit's issue tracker on GitHub, we can probably recover from this problem rather than crashing.
