在Android中将gzip json响应解压缩为字符串 [英] Decompress gzip json response to string in Android
本文介绍了在Android中将gzip json响应解压缩为字符串的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
这是我的代码:
try {
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new StringEntity(strJson, "UTF-8"));
httpPost.setHeader("api_key", "<TSssssssssssssaaa7>");
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Accept-Encoding", "gzip");
response = httpClient.execute(httpPost);
resp=EntityUtils.toString(response.getEntity(), "UTF-8");
Log.w("QueingSystem", strJson);
Log.w("QueingSystem", EntityUtils.toString(response.getEntity(), "UTF-8"));
Log.w("QueingSystem", EntityUtils.toString(response.getEntity()));
} catch (Exception e) {
Log.d("InputStream", e.getLocalizedMessage());
}
我在日志中的输出如下:
And my output in the log is as follows:
��������������V*J-.��+NU��VJ�O�&�:J���ʼn�@��ciIFj^IfrbIf~��[bfNj�Rm-���n��;������
有人可以帮助我获取String格式的json响应的确切输出吗?
Can any one please help me to get the exact output of json response in String format?
推荐答案
您必须手动检查响应是否为gzip压缩.如果是这样,您可以将响应实体包装到GzipDecompressingEntity
中以处理解压缩:
You have to manually check whether the response is gzip compressed. If it is you can wrap the response entity into a GzipDecompressingEntity
to handle the decompression:
// setup request
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new StringEntity(strJson, "UTF-8"));
httpPost.setHeader("api_key", "<TSssssssssssssaaa7>");
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Accept-Encoding", "gzip");
// execute request
response = httpClient.execute(httpPost);
HttpEntity entity = response.getEntity();
// handle gzip compression
Header contentEncodingHeader = entity.getContentEncoding();
if (contentEncodingHeader != null) {
HeaderElement[] encodings = contentEncodingHeader.getElements();
for (HeaderElement encoding : encodings) {
if (encoding.getName().equalsIgnoreCase("gzip")) {
entity = new GzipDecompressingEntity(entity);
break;
}
}
}
// get response content
resp = EntityUtils.toString(entity, "UTF-8");
