Android HttpClient获取json数据丢失

Question

androidjsonhttpHttpClient

Answer 1

你用电脑的浏览器IE测试一下那个URL,看看返回什么，先排除后台的原因

Answer 2

也就是才能取到一半的json数据，浏览器里测试是好的，能得到全部数据，我用HttpClient就只能取到接口返回数据的一半。

Answer 3

试一下如下代码看看：
HttpClient hc = new DefaultHttpClient();  
    try {  
        HttpResponse ht = hc.execute(httpGet);  
        if(ht.getStatusLine().getStatusCode() == HttpStatus.SC_OK){  
            HttpEntity he = ht.getEntity();  
            InputStream is = he.getContent();  
            BufferedReader br = new BufferedReader(new InputStreamReader(is));  
            String response = "";  
            String readLine = null;  
            while((readLine =br.readLine()) != null){  
                //response = br.readLine();  
                response = response + readLine;  
            }  
            is.close();  
            br.close();  
              
            //String str = EntityUtils.toString(he);  
            System.out.println("========="+response);  
            return response;  
        }else{  
            return "error";  
        }  
    } catch (ClientProtocolException e) {  
        // TODO Auto-generated catch block  
        e.printStackTrace();  
        return "exception";  
    } catch (IOException e) {  
        // TODO Auto-generated catch block  
        e.printStackTrace();  
        return "exception";  
    }
另外何不考虑使用HttpUrlConnection？这个帖子对比了HttpUrlConnection和HttpClient，我觉得说的不错

哥们，你给的这个函数我使用后还是不行，和原来的效果一样。为什么会这样呢？求解答啊，，，？？？？？？？？？？？public static String test(String url,List<NameValuePair> params){

HttpParams httpParams;
HttpClient httpClient;
HttpPost httpRequest = new HttpPost(url);
String response = "doPostError";
httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, 4*1000);
HttpConnectionParams.setSoTimeout(httpParams, 6*1000);
HttpConnectionParams.setSocketBufferSize(httpParams, 8192);
HttpClientParams.setRedirecting(httpParams, true);
String userAgent ="Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.2) Gecko/20100115 Firefox/3.6";
HttpProtocolParams.setUserAgent(httpParams, userAgent);
httpClient = new DefaultHttpClient(httpParams);
try {
if (params != null) {
httpRequest.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
}
httpClient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION,HttpVersion.HTTP_1_0);
httpClient.getParams().setParameter(CoreProtocolPNames.HTTP_CONTENT_CHARSET,"UTF-8");
HttpResponse httpResponse = httpClient.execute(httpRequest);
if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
HttpEntity httpEntity=httpResponse.getEntity();
InputStream is = httpEntity.getContent();  
 BufferedReader br = new BufferedReader(new InputStreamReader(is));  
            String readLine = null;  
            while((readLine =br.readLine()) != null){  
                //response = br.readLine();  
                response = response + readLine;  
            }  
            is.close();  
            br.close();  
} else {
response = "Error Response: " + httpResponse.getStatusLine().toString();//获取响应码  
}
} catch (ClientProtocolException e) {
// strResult = e.getMessage().toString();
e.printStackTrace();
} catch (IOException e) {
// strResult = e.getMessage().toString();
e.printStackTrace();
}catch (Exception e) {
// strResult = e.getMessage().toString();
e.printStackTrace();
} System.out.println("strResult =" + response); return response;
}

Answer 5

while((readLine =br.readLine()) != null){  是不是你的循环语句写的有问题啊，看着别扭呢HttpEntity httpEntity = new UrlEncodedFormEntity(pairs);
httpPost.setEntity(httpEntity);
HttpResponse httpResponse = httpClient.execute(httpPost);
if (httpResponse.getStatusLine().getStatusCode() == 200) {
HttpEntity entity = httpResponse.getEntity();
return EntityUtils.toString(entity, "utf-8");
用这个，直接转成String试试。

Answer 6

你看下回来的那个String，是否完整的，，，
