我正在編寫Android 2.2應用程序，將json嚴格性發布到ReSTfull Web服務。Android HTTPPost返回錯誤「方法不允許」。
提琴手調用與相同的Json返回Web服務預期，並且具有相同的Json返回預期一個aspx的Web應用程序。
當我看到服務器日誌，我可以看到服務器響應初始POST動詞用307重定向，然後立即一個GET和405錯誤。
提琴手和ASPX應用程序日誌有307重定向POST，然後立即另一個POST和200確定。
這是怎麼回事？
這是主要活動：
package com.altaver.android_PostJson2;
import org.json.JSONException;
import org.json.JSONObject;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class PostJson extends Activity {
private static final String TAG = "MainActivity";
private static final String URL = "http://web2.altaver.com/sdz/avReSTfulLogin1";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
JSONObject jsonObjSend = new JSONObject();
try {
jsonObjSend.put("Pass", "sz");
jsonObjSend.put("User", "szechman");
Log.i(TAG, jsonObjSend.toString(2));
} catch (JSONException e) {
e.printStackTrace();
}
JSONObject jsonObjRecv = HttpClient.SendHttpPost(URL, jsonObjSend);
//examine JSONObject later
}
}
這是類代碼做Web服務調用：
package com.altaver.android_PostJson2;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import org.apache.http.Header;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;

import org.apache.http.impl.client.DefaultHttpClient;
import org.json.JSONObject;
import android.util.Log;
public class HttpClient {
private static final String TAG = "HttpClient";
public static JSONObject SendHttpPost(String URL, JSONObject jsonObjSend) {
try {
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpClientParams.setRedirecting(httpclient.getParams(), true);
//added cookie policy, wild shot in the dark
//httpclient.getParams().setParameter(ClientPNames.COOKIE_POLICY, >CookiePolicy.RFC_2109);
HttpPost httpPostRequest = new HttpPost(URL);
StringEntity se;
se = new StringEntity(jsonObjSend.toString());
// Set HTTP parameters
httpPostRequest.setEntity(se);
//httpPostRequest.setHeader("User-Agent", >"com.altaver.android_PostJson2");
httpPostRequest.setHeader("User-Agent", "Mozilla/5.0 (Windows; U; >Windows NT 5.1; en-US; rv:1.9.2.3) Gecko/20100401");
httpPostRequest.setHeader("Accept", "application/json");
httpPostRequest.setHeader("Content-Type", "application/json");
long t = System.currentTimeMillis();
HttpResponse response = (HttpResponse) >httpclient.execute(httpPostRequest);
Log.i(TAG, "HTTPResponse received in [" + >(System.currentTimeMillis()-t) + "ms]");
HttpEntity entity = response.getEntity();
if (entity != null) {
InputStream instream = entity.getContent();
Header contentEncoding = response.getFirstHeader("Content-Encoding");
String resultString= convertStreamToString(instream);
instream.close();
resultString = resultString.substring(1,resultString.length()-1); // >remove wrapping "[" and "]"
JSONObject jsonObjRecv = new JSONObject(resultString);
Log.i(TAG,"<jsonobject>\n"+jsonObjRecv.toString()+"\n</jsonobject>");
return jsonObjRecv;
}
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}
private static String convertStreamToString(InputStream is) {
/*
* To convert the InputStream to String we use the >BufferedReader.readLine()
* method. We iterate until the BufferedReader return null which means

BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
}
非常感謝您的幫助，湯姆。這是正確的答案。 – 2011-07-07 00:47:41
@Stuart，你距離毫米。你給了我一個很大的問題。 – 2011-07-07 01:17:11
