httpclient post HTTPS 后获取不到完整网页前台代码
httpclient post HTTPS 后获取不到完整网页前台代码只能获取3分一的，
然后 读取流 就报了 以下的错
java.io.IOException: Attempted read from closed stream.
at org.apache.http.impl.io.ContentLengthInputStream.read(ContentLengthInputStream.java:133)
at org.apache.http.conn.EofSensorInputStream.read(EofSensorInputStream.java:121)
--------------------编程问答-------------------- 换BufferedInputStream试试 --------------------编程问答--------------------
DefaultHttpClient httpClient = new DefaultHttpClient();
try {
TrustManager easyTrustManager = new MyX509TrustManager();
SSLContext sslcontext = SSLContext.getInstance("TLS");
sslcontext
.init(null, new TrustManager[] { easyTrustManager }, null);
SSLSocketFactory sf = new SSLSocketFactory(sslcontext);
Scheme sch = new Scheme("https", 443, sf);
httpClient.getConnectionManager().getSchemeRegistry().register(sch);
// 设置连接超时
httpClient.getParams().setParameter(
CoreConnectionPNames.CONNECTION_TIMEOUT, 60 * 1000);
// 设置读取超时
httpClient.getParams().setParameter(
CoreConnectionPNames.SO_TIMEOUT, 60 * 1000);
HttpPost httpPost = new HttpPost(url);
List<NameValuePair> formParams = new ArrayList<NameValuePair>(); // 创建参数队列
// 封装请求参数
int paramSize = Constants.StepOnePageIDsList.size();
for (int i = 0; i < paramSize; i++) {
formParams.add(new BasicNameValuePair(Constants.StepOnePageIDsList.get(i),
Constants.StepOnePageIDsValList.get(i)));
}
httpPost.setEntity(new UrlEncodedFormEntity(formParams, "UTF-8"));
HttpResponse response = httpClient.execute(httpPost);
HttpEntity entity = response.getEntity();
String content = EntityUtils.toString(entity);
InputStream in = entity.getContent();
byte b[] = new byte[1024];
int len = 0;
int temp=0; //所有读取的内容都使用temp接收
while((temp=in.read())!=-1){ //当没有读取完时，继续读 取 》》》》报错
b[len]=(byte)temp;
len++;
}
in.close();
System.out.println(new String(b,0,len));
我用了 BufferedInputStream 之后 就没有那个错， 但是 还是 获取不到 完整的网页前台HTMl代码 郁闷， 代码如下：
--------------------编程问答-------------------- getResponseBodyAsString
HttpResponse response = httpClient.execute(httpPost);
HttpEntity entity = response.getEntity();
BufferedInputStream bufferedInput = null;
byte[] buffer = new byte[1024];
try {
// 创建BufferedInputStream 对象
bufferedInput = new BufferedInputStream(
entity.getContent());
int bytesRead = 0;
// 从文件中按字节读取内容，到文件尾部时read方法将返回-1
while ((bytesRead = bufferedInput.read(buffer)) != -1) {
// 将读取的字节转为字符串对象
String chunk = new String(buffer, 0, bytesRead);
System.out.print(chunk);
}
} catch (FileNotFoundException ex) {
ex.printStackTrace();
} catch (IOException ex) {
ex.printStackTrace();
} finally {
// 关闭 BufferedInputStream
try {
if (bufferedInput != null)
bufferedInput.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
补充：Java , Java EE
