Android 安卓文件上传
我想使用http将文件上载到服务器Android 安卓文件上传,android,http,file-upload,Android,Http,File Upload,我想使用http将文件上载到服务器 try { URL url = new URL(dst); File file = new File(src); urlconnection = url.openConnection(); urlconnection.setDoOutput(true); urlconnection.setDoInput(true); if
try {
URL url = new URL(dst);
File file = new File(src);
urlconnection = url.openConnection();
urlconnection.setDoOutput(true);
urlconnection.setDoInput(true);
if (urlconnection instanceof HttpURLConnection) {
try {
((HttpURLConnection)urlconnection).setRequestMethod("PUT");
((HttpURLConnection)urlconnection).setRequestProperty("Content-type", "text/html");
((HttpURLConnection)urlconnection).connect();
} catch (ProtocolException e) {
e.printStackTrace();
}
}
BufferedOutputStream bos = new BufferedOutputStream(urlconnection
.getOutputStream());
BufferedInputStream bis = new BufferedInputStream(new FileInputStream(
file));
int i;
// read byte by byte until end of stream
while ((i = bis.read()) >0) {
bos.write(i);
}
System.out.println(((HttpURLConnection)urlconnection).getResponseMessage());
}
catch(Exception e1)
{
e1.printStackTrace();
}
try {
InputStream inputStream;
int responseCode=((HttpURLConnection)urlconnection).getResponseCode();
if ((responseCode>= 200) &&(responseCode<=202) ) {
inputStream = ((HttpURLConnection)urlconnection).getInputStream();
int j;
while ((j = inputStream.read()) >0) {
System.out.println(j);
}
} else {
inputStream = ((HttpURLConnection)urlconnection).getErrorStream();
}
((HttpURLConnection)urlconnection).disconnect();
} catch (IOException e) {

试试看{
URL=新URL（dst）；
文件=新文件（src）；
urlconnection=url.openConnection（）；
urlconnection.setDoOutput（true）；
urlconnection.setDoInput（true）；
if（HttpURLConnection的urlconnection实例）{
试一试{
（（HttpURLConnection）urlconnection.setRequestMethod（“PUT”）；
（HttpURLConnection）urlconnection.setRequestProperty（“内容类型”、“文本/html”）；
（（HttpURLConnection）urlconnection.connect（）；
}捕获（协议例外e）{
e、 printStackTrace（）；
}
}
BufferedOutputStream bos=新的BufferedOutputStream（urlconnection
.getOutputStream（））；
BufferedInputStream bis=新BufferedInputStream（新文件输入流(
档案);；
int i；
//逐字节读取，直到流结束
而（（i=bis.read（））>0）{
bos.write（i）；
}
System.out.println（（（HttpURLConnection）urlconnection.getResponseMessage（））；
}
捕获（异常e1）
{
e1.printStackTrace（）；
}
试一试{
输入流输入流；
int responseCode=（（HttpURLConnection）urlconnection.getResponseCode（）；
如果（（响应代码>=200）和&（响应代码0）{
系统输出println（j）；
}
}否则{
inputStream=（（HttpURLConnection）urlconnection.getErrorStream（）；
}
（（HttpURLConnection）urlconnection.disconnect（）；
}捕获（IOE异常）{
e、 printStackTrace（）；
}
您确定您的服务器侦听PUT请求吗？可能尝试POST。当我尝试POST时，是否写入“不允许方法”您确定您的服务器侦听PUT请求吗？可能尝试POST。当我尝试POST时，是否写入“不允许方法”是否编写此代码也适用于.net webservice？如果是，请发布webmethod结构。我得到的响应代码为200，但在服务器上没有得到任何信息。此代码也适用于.net webservice吗？如果是，请发布webmethod结构。我得到的响应代码为200，但在服务器上没有得到任何信息。
