这是我的jsonparser类,我在httpPost.setEntity的params中遇到错误(new UrlEncodedFormEntity(params));
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
public JSONParser() {
}
public JSONObject makeHttpRequest(String url, String method,
List<Pair<String,String>> params) {
try {
if (method == "GET") {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} else if (method == "GET") {
DefaultHttpClient httpClient = new DefaultHttpClient();
String paramString = URLEncodedUtils.format(params, "utf-8");
url += "?" + paramString;
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "UTF-8"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}
这是我使用名称值对
的UrlEncodedFormEntity类public class UrlEncodedFormEntity extends org.apache.http.entity.StringEntity
{
public UrlEncodedFormEntity(java.util.List<? extends
org.apache.http.NameValuePair> parameters, java.lang.String encoding)
throws java.io.UnsupportedEncodingException { /* compiled code */ }
public UrlEncodedFormEntity(java.util.List<? extends
org.apache.http.NameValuePair> parameters) throws
java.io.UnsupportedEncodingException { /* compiled code */ }
}
