本文介绍了JAVA EOFException类时的getInputStream从POST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
林试图从POST响应但是当我做输入抛出
和例外
{尝试
康恩=(HttpURLConnection类)url.openConnection();
conn.setDoOutput(真);
conn.setDoInput(真);
// Marcamos一个三分球时代报德的Maximo埃斯佩拉
conn.setReadTimeout(3000);
conn.setUseCaches(真);
conn.setFixedLengthStreamingMode(bytes.length);
conn.setRequestMethod(POST);
conn.setRequestProperty(内容类型,
应用程序/ x-WWW的形式urlen codeD;字符集= UTF-8);
//张贴请求
// Abrimos UNAseñal德萨利达
OutputStream的OUT = conn.getOutputStream();
out.write(字节);
了out.flush();
字符串缓冲区;
// Abrimos UNAseñal德ENTRADA
在这里,Android抛出和异常
InputStreamReader的IP =新的InputStreamReader(conn.getInputStream());
的BufferedReader IN2 =新的BufferedReader(IP);
// Bucle阙recoge托达拉斯respuestas 而((缓冲= in2.readLine())!= NULL){
Log.e(,缓冲液);
}
// Cerramos拉斯Senales的德ENTRADAÿ萨利达
in2.close();
out.close(); }赶上(IOException异常五){
Log.e(TAG,ERROR+ e.toString());
e.printStackTrace();
} {最后
conn.disconnect();
}
和LOG标记显示如下:

解决方案
我在应用程序中使用HTTP POST一次,使用这种code,它工作得很好。如果你愿意,你可以尝试一下。
公共无效posthttp()
{ URL =您的网址
InputStream为= NULL;
串VAL1;
字符串val2的;
ArrayList的<&的NameValuePair GT;的NameValuePair =新的ArrayList<&的NameValuePair GT;(); //使HTTP请求
尝试{
// defaultHttpClient
DefaultHttpClient的HttpClient =新DefaultHttpClient(); namevaluepair.add(新BasicNameValuePair(VAL1,VAL1));
namevaluepair.add(新BasicNameValuePair(val2的,将val2));
字符串enc_url = urlEn code(URL);
HttpPost httpPost =新HttpPost(enc_url); httpPost.setEntity(新UrlEn codedFormEntity(的NameValuePair));
HTT presponse HTT presponse = httpClient.execute(httpPost);
HttpEntity httpEntity = HTT presponse.getEntity();
是= httpEntity.getContent(); }赶上(UnsupportedEncodingException五){
e.printStackTrace();
}赶上(ClientProtocolException E){
e.printStackTrace();
}赶上(IOException异常五){
e.printStackTrace();
} 尝试{
读者的BufferedReader =新的BufferedReader(新的InputStreamReader(
是,ISO-8859-1),8);
StringBuilder的SB =新的StringBuilder();
串线= NULL;
而((行= reader.readLine())!= NULL){
sb.append(线);
}
is.close();
串responseFromServer = sb.toString(); }赶上(例外五){
Log.e(缓冲区错误,错误转换结果+ e.toString());
}}
Im trying to get the response from POST but when I do the Input throws
and exception
try {
conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setDoInput(true);
// Marcamos a 3s el tiempo maximo de espera
conn.setReadTimeout(30000000);
conn.setUseCaches(true);
conn.setFixedLengthStreamingMode(bytes.length);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded;charset=UTF-8");
// post the request
// Abrimos una señal de salida
OutputStream out = conn.getOutputStream();
out.write(bytes);
out.flush();
String buffer;
// Abrimos una señal de entrada
here is where android throws and exception
InputStreamReader ip = new InputStreamReader(conn.getInputStream());
BufferedReader in2 = new BufferedReader(ip);
// Bucle que recoge todas las respuestas
while ((buffer = in2.readLine()) != null) {
Log.e(" ", buffer);
}
// Cerramos las señales de entrada y salida
in2.close();
out.close();
} catch (IOException e) {
Log.e(TAG, "ERROR" + e.toString());
e.printStackTrace();
} finally {
conn.disconnect();
}
And LOG TAG shows this:

解决方案
I used http post once in my application, using this code, and it worked fine. You can try it if you wish.
public void posthttp()
{
URL= your url
InputStream is = null;
String val1;
String val2;
ArrayList<NameValuePair> namevaluepair =new ArrayList<NameValuePair>();
//Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
namevaluepair.add(new BasicNameValuePair("val1",val1));
namevaluepair.add(new BasicNameValuePair("val2",val2));
String enc_url = urlEncode(URL);
HttpPost httpPost = new HttpPost(enc_url );
httpPost.setEntity(new UrlEncodedFormEntity(namevaluepair));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line);
}
is.close();
String responseFromServer = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
}
