首先,我收到状态代码 200。在 php 脚本中,我只是让代码将发送到服务器的内容通过邮件发送给我(同时我尝试进行调试)。使用 var_dump $_POST 或 $_REQUEST 我收到一封空白电子邮件。如果我在 $_SERVER 上运行 foreach,我会得到一些数据,例如 HTTP_USER_AGENT : Apache-HttpClient/UNAVAILABLE (java 1.4) 和 CONTENT_LENGTH : 9
我不明白为什么没有发布数据?我是 Android 新手,我确实是边学边做。
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(dest_url);
//httppost.setHeader("Accept", "application/json");
//httppost.setHeader("Content-type", "application/json");
//JSONObject json = new JSONObject();
// Add your data
//json.put("action", "login");
//json.put("username", "kermit");
//json.put("password", "123456");
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
//nameValuePairs.add(new BasicNameValuePair("myjson", json.toString()));
nameValuePairs.add(new BasicNameValuePair("plswork", "hi"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8));
//StringEntity str_json = new StringEntity(json.toString());
//httppost.setEntity(str_json);
HttpResponse response;
response = httpclient.execute(httppost);
我的manifestxml有以下行;
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
这些是我的进口;
import java.io.IOException;
import java.util.ArrayList;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.protocol.HTTP;
import org.json.JSONObject;
import android.app.Activity;

最佳答案
这很可能与你的情况有关
httppost.setHeader("Content-type", "application/json");
application/json
不是 HTTP POST 表单提交的正常内容类型。考虑到您并不是真正发送 json,而是发送标准 POST 实体 (nameString=valueString),请尝试将其更改为
httppost.setHeader("Content-Type", "application/x-www-form-urlencoded")
看看这是否能解决您的问题。或者更好的是,将其全部删除。
我在我的应用程序中使用了这段代码 - 它工作得很好:
HttpPost httppost = new HttpPost(SERVER_URL);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("REQUEST", req));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, "UTF-8"));
HttpResponse response = httpclient.execute(httppost);
本例中的响应是 text/xml
- 但这并不重要。
