SSL断开的管道
我在我的应用程序和somtimes（如果我有大量的Post数据）发出POST请求，发生以下错误：
avax.net.ssl.SSLException：写入错误：ssl = 0x2f0610：系统调用期间发生I / O错误，中断管道
同时在下面的代码中执行http.execute（httpost）。 有人知道如何避免这种情况吗？
我尝试使用AndroidHttpClient，但无法找到基本身份验证的有效方式而我尝试了一个HttpsUrlConnection，但得到相同的错误。
public static String makePOSTRequest(String s, List<NameValuePair> nvps,
String encoding) {
String ret = "";
UsernamePasswordCredentials c = new UsernamePasswordCredentials("XXX", "YYY");
BasicCredentialsProvider cP = new BasicCredentialsProvider();
cP.setCredentials(AuthScope.ANY, c);
HttpParams httpParams = new BasicHttpParams();
int connection_Timeout = 5000;
HttpConnectionParams.setConnectionTimeout(httpParams,
connection_Timeout);
HttpConnectionParams.setSoTimeout(httpParams, connection_Timeout);
DefaultHttpClient http = new DefaultHttpClient(httpParams);
http.setCredentialsProvider(cP);
HttpResponse res;
try {
HttpPost httpost = new HttpPost(s);
httpost.setEntity(new UrlEncodedFormEntity(nvps,
HTTP.DEFAULT_CONTENT_CHARSET));
res = http.execute(httpost);
InputStream is = res.getEntity().getContent();
BufferedInputStream bis = new BufferedInputStream(is);
ByteArrayBuffer baf = new ByteArrayBuffer(50);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte) current);
}
res = null;
httpost = null;
ret = new String(baf.toByteArray(), encoding);
break;
} catch (ClientProtocolException e) {
ret = e.getMessage();
} catch (IOException e) {
ret = e.getMessage();
}
return ret;
}
编辑：下面的代码用于上传文件，如果我尝试上传小文件，则代码有效，但如果文件变大，我收到破损的管道错误。 使用更快的Internet连接会增加文件大小，这似乎是服务器重置连接之前的时间问题。
public static boolean upload_image2(String url,
List<NameValuePair> nameValuePairs, File file, String encoding) {
boolean erg = false;
HttpParams httpParams = new BasicHttpParams();
int connection_Timeout = 120000;
HttpConnectionParams.setConnectionTimeout(httpParams,connection_Timeout);
HttpConnectionParams.setSoTimeout(httpParams, connection_Timeout);
http = new DefaultHttpClient(httpParams);
HttpResponse res;
UsernamePasswordCredentials c = new UsernamePasswordCredentials(username, password);
BasicCredentialsProvider cP = new BasicCredentialsProvider();
cP.setCredentials(AuthScope.ANY, c);
try {
HttpPost httpost = new HttpPost(url);
MultipartEntity entity = new MultipartEntity(
HttpMultipartMode.STRICT);
FileBody isb = new FileBody(file, "application/*");
entity.addPart("File", isb);
for (int index = 0; index < nameValuePairs.size(); index++) {
ContentBody cb;
// Normal string data
cb = new StringBody(nameValuePairs.get(index).getValue(),
"", null);
entity.addPart(nameValuePairs.get(index).getName(), cb);
}
httpost.setEntity(entity);
res = http.execute(httpost);
InputStream is = res.getEntity().getContent();
BufferedInputStream bis = new BufferedInputStream(is);
ByteArrayBuffer baf = new ByteArrayBuffer(50);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte) current);
}
res = null;
httpost = null;
String ret = new String(baf.toByteArray(), encoding);
LastError = ret;
erg = true;
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
LastError = e.getMessage();
erg = false;
} catch (IOException e) {
// TODO Auto-generated catch block
LastError = e.getMessage();
erg = false;
}
return erg;
}
我使用DefaultHttpClient时遇到了同样的问题，使用我自己的httpclient实现来支持https。 小文件工作正常，大文件一次又一次地失败。
阅读这个回应后，我已经改变到HttpsURLConnection接受的答案建议，也因为它是由Android推荐（http://android-developers.blogspot.pt/2011/09/androids-http-clients.html）。
问题在于。 原来问题出在服务器上，我已经改变了PHP服务器的配置以接受更大的尺寸，但我完全忘记了更改nginx的client_max_body_size 。 做出这个小改动后，发送大文件正在工作。 通过HttpsUrlConnections和DefaultHttpClient。
我无法用DefaultHttpClient，AndroidHttpClient或Abstract解决问题，但最终通过头部而不是CredentielsService找到了使用HttpsUrlRequest和ant身份验证的解决方案：
public static boolean upload_image5(String urls,File file, String encoding){
HttpURLConnection connection = null;
DataOutputStream outputStream = null;
DataInputStream inputStream = null;
String myfilename = file.getName();
String urlServer = urls;
String lineEnd = "rn";
String twoHyphens = "--";
String boundary = "*****";
boolean erg = false;
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;
try
{
FileInputStream fileInputStream = new FileInputStream(file);
URL url = new URL(urlServer);
connection = (HttpsURLConnection) url.openConnection();
// Allow Inputs & Outputs
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
// Enable POST method
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);
connection.addRequestProperty("Authorization","Basic [YOUR MD5 LOGIN VALUE]");
outputStream = new DataOutputStream( connection.getOutputStream() );
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name="DestFileName"");
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(myfilename);
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name="Target"" );
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(lineEnd);
outputStream.writeBytes("DOC");
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name="filename"");
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(myfilename);
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name="File"; filename="" + myfilename + """);
outputStream.writeBytes(lineEnd);
outputStream.writeBytes("Content-Type: application/*");
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(lineEnd);
//hier File schreiben
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0)
{
outputStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
fileInputStream.close();
try {
inputStream = new DataInputStream(connection.getInputStream());
StringBuilder response = new StringBuilder();
String line;
while ((line = inputStream.readLine()) != null) {
response.append(line).append('n');
}
LastError =response.toString();
erg = true;
} catch (IOException e) {
LastError = e.getMessage();
erg = false;
} finally {
if (inputStream != null){
try {
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
outputStream.flush();
outputStream.close();
}
catch (Exception ex)
{
LastError = ex.getMessage();
erg = false;
}
return erg;
}
我有同样的错误。 问题出在Android库中使用DefaultHttpClient已经出现，因为Android API级别1和AndroidHttpClient自Android API级别8以来一直可用。这是Android中的错误https://code.google.com/p/android/issues /细节？ID = 8625
我的问题是：默认的超时时间是60秒。 当我在Wireshark中运行连接时。 这是创建握手，他一直在等待ApplicationData，但他没有得到它，所以超时后发送FIN和我得到：javax.net.ssl.SSLException：写入错误：ssl = 0x2f0610：I / O错误期间系统调用，断开的管道。
我解决了我的问题问题设置超时5分钟的http连接或某些值超过60秒。 如果我可以推荐如何解决你的问题在服务器Wireshark上运行，并用移动设备监听通信。
