Android-Httpclient数据解析

发布于 2016-11-29 18:30:33 字数 347 浏览 1322 评论 4

最近在做一个联网的小程序，使用httpclient去请求服务器，获得返回数据。
。。。

mResponse = mClient.execute(get);
String charset = EntityUtils.getContentCharSet(mResponse.getEntity());//获得的是utf-8
byte[] bResultXml = EntityUtils.toByteArray(mResponse.getEntity());
String content=new String(bResultXml,charset)

在你发送请求的的时候就要指定编码格式。直接上代码：

public String sendHttpGet(String url, String charset) {
final HttpClient httpClient = new HttpClient();
final GetMethod getMethod = new GetMethod(url);
getMethod.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, charset);
getMethod.getParams().setSoTimeout(5000);
getMethod.addRequestHeader("Referer", "http://www.baidu.com");
getMethod.addRequestHeader("User-Agent",
"Mozilla/5.0 (Windows NT 5.1) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.52 Safari/536.5");
String result = null;
// 执行postMethod
int statusCode = 0;
try {
statusCode = httpClient.executeMethod(getMethod);
} catch (HttpException e) {
log.error(e.getMessage());
} catch (IOException e) {
log.error(e.getMessage());
}
if (statusCode == HttpStatus.SC_OK) {
try {
InputStream input = getMethod.getResponseBodyAsStream();
result = inputStream2String(input, charset);
} catch (IOException e) {
e.getMessage();
}

}

getMethod.releaseConnection();
return result;
}

需要手动去指定编码：

EntityUtils.toString(httpResponse.getEntity(),HTTP.UTF_8);

一般请求代码如下：

HttpClient httpclient = new DefaultHttpClient();
HttpPost request = new HttpPost(URL);
StringEntity s = new StringEntity(resqueString, HTTP.UTF_8);
s.setContentType("text/xml charset=utf-8");
request.setEntity(s);
HttpResponse httpResponse=httpclient.execute(request);
return EntityUtils.toString(httpResponse.getEntity(),HTTP.UTF_8

);
