我是Retrofit的新手,但它似乎非常强大.
使用普通的 JSON一切正常,但是当我尝试使用GZIP的时,我就会收到一个错误:
使用普通的 JSON一切正常,但是当我尝试使用GZIP的时,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:
Expected BEGIN_OBJECT but was STRING at line 1 column 1
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()); } });
结果:-line从未显示过,但我在RetrofitLog中看到了许多这些东西:T Mk A G 4. @ A .
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:
HTTP/1.1 200 OK Accept-Ranges: bytes Connection: close Content-Length: 477 Content-Type: application/x-gzip ETag: "2cc40cb-1dd-..."

原始服务器:

解决方法
感谢
Jake Whartons comment,结果发现Content-Encoding:gzip标头丢失了.
因为我告诉服务器添加这些标题,一切正常:

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