改造+ OkHttp + GZIP-ed JSON

Question

我是Retrofit的新手,但它似乎非常强大.使用普通的JSON一切正常,但是一旦我尝试了GZIPed,我就会收到一个错误:

I/System.out(14883):------ retrofit.RetrofitError:retrofit.converter.ConversionException:com.google.gson.JsonSyntaxException:java.lang.IllegalStateException:预期BEGIN_OBJECT但在第1行第1列是STRING

显然,我在Log中看到的乱码符号无法解析为JSON.

我认为okHttp是正确的gzip东西？我错过了什么？

这些罐子在我的libs文件夹中:

retrofit-1.6.1.jar
okhttp-2.0.0.jar
gson-2.2.4.jar

这样我开始通话:

public interface OvlService {
    @GET("/gziptest.gz")
    void getOvls(Callback<OvlWrapper> callback);
}
...
OkHttpClient okHttpClient = new OkHttpClient();
Executor executor = Executors.newCachedThreadPool();
RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint("http://my.domain") // The base API endpoint.
.setLogLevel(RestAdapter.LogLevel.FULL)
.setExecutors(executor, executor)
.setClient(new OkClient(okHttpClient))
.build();

OvlService ovlService = restAdapter.create(OvlService.class);

ovlService.getOvls(new Callback<OvlWrapper>() {

    @Override
    public void success(OvlWrapper arg0, Response arg1) {
        System.out.println("result: " + arg0.toString());
    }
});

该result:线路处于从未显示,而是我看到很多的这些东西T?? ?????=?Mk?A?G?4.??@??A??在RetrofitLog.gzip没有解压缩我怎么办？谢谢!

编辑:

我在我的测试服务器(server.com/ovl.gz)上使用gzip文件尝试了它,我也尝试使用原始的api服务器(server2.com/api.php?id=ovlgzip).结果相同,但标题不同:

测试服务器:

感谢杰克·沃顿的评论，结果发现Content-Encoding: gzip标题丢失了。由于我告诉服务器添加这些标头，所以一切正常：

<?php
$data = ...;
$gzdata = gzencode($data, 9, FORCE_GZIP);
header('Content-Encoding: gzip');
header('Content-Length: '.strlen($gzdata));
... ?>
