问题描述
当我在浏览器中复制并粘贴HttpGet的getRequest对象的值时,它给出了正确的结果但是当我在Eclipse中通过模拟器运行它时会抛出异常。
提前感谢捆绑如果有任何想法的话。
When i copy and paste the value of getRequest object of HttpGet in the browser it gives me the correct result But when i run it in Eclipse by emulator it throws exception.
Bundle of thanks in advance if any idea about it.
public static String callWebService(String webMethod){
// HTTP get client
String serviceURL = "http://localhost:6158/Host/Service1.svc/";
serviceURL += webMethod;
HttpClient client=new DefaultHttpClient();
HttpGet getRequest=new HttpGet();
try {
// construct a URI object
getRequest.setURI(new URI(serviceURL));
} catch (URISyntaxException e) {
Log.e("URISyntaxException", e.toString());
}
// buffer reader to read the response
BufferedReader in=null;
// the service response
HttpResponse response=null;
try {
// execute the request
response = client.execute(getRequest);
} catch (ClientProtocolException e) {
Log.e("ClientProtocolException", e.toString());
} catch (IOException e) {
Log.e("IO exception", e.toString());
}
try {
in=new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
} catch (IllegalStateException e) {
Log.e("IllegalStateException", e.toString());
} catch (IOException e) {
Log.e("IO exception", e.toString());
}
StringBuffer buff=new StringBuffer("");
String line="";
try {
while((line=in.readLine())!=null)
{
buff.append(line);
}
} catch (IOException e) {
Log.e("IO exception", e.toString());
return e.getMessage();
}
try {
in.close();
} catch (IOException e) {
Log.e("IO exception", e.toString());
}
// response, need to be parsed
return buff.toString();
}
LogCat如下:
