我知道该okhttp3库默认情况下会添加标头Accept-Encoding: gzip并自动为我们解码响应。
我正在处理的问题是一个只接受标头的主机,例如:Accept-Encoding: gzip, deflate如果我不添加该deflate部分,它就会失败。现在,当我手动将该标头添加到 okhttp 客户端时,该库不再为我进行解压缩。
我尝试了多种解决方案来获取响应并尝试手动解压缩它,但我总是以异常结束,即java.util.zip.ZipException: Not in GZIP format,这是我迄今为止尝试过的:
//decompresser
public static String decompressGZIP(InputStream inputStream) throws IOException
{
InputStream bodyStream = new GZIPInputStream(inputStream);
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
byte[] buffer = new byte[4096];
int length;
while ((length = bodyStream.read(buffer)) > 0)
{
outStream.write(buffer, 0, length);
}
return new String(outStream.toByteArray());
}
//run scraper
scrape(api, new Callback()
{
// Something went wrong
@Override
public void onFailure(@NonNull Call call, @NonNull IOException e)
{
}
@Override
public void onResponse(@NonNull Call call, @NonNull Response response) throws IOException
{
if (response.isSuccessful())
{
try
{
InputStream responseBodyBytes = responseBody.byteStream();
returnedObject = GZIPCompression.decompress(responseBodyBytes);
if (returnedObject != null)
{
String htmlResponse = returnedObject.toString();
}
}
catch (ProtocolException e){}
if(response != null) response.close();
}
}
});
private Call scrape(Map<?, ?> api, Callback callback)
{
MediaType JSON = MediaType.parse("application/json; charset=utf-8");
String method = (String) api.get("method");
String url = (String) api.get("url");
Request.Builder requestBuilder = new Request.Builder().url(url);
请注意,响应标头将始终返回Content-Encoding: gzip并且Transfer-Encoding: chunked
还有一件事,我也尝试过本主题中的解决方案,但它仍然以D/OkHttp: java.io.IOException: ID1ID2: actual 0x00003c68 != expected 0x00001f8b.
任何帮助,将不胜感激..
