我有上述网络服务，现在我想在关键字“回答”中将数据发布到此网络服务。如何解析并将我的数组字符串放入“answer”键？
我的代码如下。但它会在出现错误时给出响应..
@Override
protected String doInBackground(String... urls) {
HttpClient httpClient= new DefaultHttpClient();
HttpContext context=new BasicHttpContext();
HttpPost httpPost=new HttpPost(url);
JSONObject json=new JSONObject();
httpPost.setHeader("Content-type",
"application/json; charset=UTF-8");
try {
//json.put("EmailID","test@yahoo.com");
//json.put("ProjID","78");
//json.put("UID", "1");
//json.put("ProjectInviterFQAnswer", "Object");
StringEntity stringEntity = new StringEntity(json.toString());
InputStream stream= new
ByteArrayInputStream(json.toString().getBytes("UTF-8"));
httpPost.setEntity(new StringEntity(json.toString()));
HttpResponse httpResponse= httpClient.execute(httpPost,context);
BufferedReader reader= new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent(),"UTF-8"));
res= reader.readLine();
resp=res.toString();
Log.e("RESPONSE OF WEBSER:", resp);
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return res;

以ArrayList NameValuePair为例
ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();
然后在答案键中添加您的参数，如下所示
postParameters.add(new BasicNameValuePair("answer",
"Your value"));
String response = null;
try {
response = CustomHttpClient
.executeHttpPost(
"Your Url", postParameters);`
CustomHTTPClient方法
public class CustomHttpClient {
/** The time it takes for our client to timeout */
public static final int HTTP_TIMEOUT = 30 * 1000; // milliseconds
/** Single instance of our HttpClient */
private static HttpClient mHttpClient;
/**
* Get our single instance of our HttpClient object.
*
* @return an HttpClient object with connection parameters set
*/
private static HttpClient getHttpClient() {
if (mHttpClient == null) {
mHttpClient = new DefaultHttpClient();
final HttpParams params = mHttpClient.getParams();
HttpConnectionParams.setConnectionTimeout(params, HTTP_TIMEOUT);
HttpConnectionParams.setSoTimeout(params, HTTP_TIMEOUT);
ConnManagerParams.setTimeout(params, HTTP_TIMEOUT);
}
return mHttpClient;
}
/**
* Performs an HTTP Post request to the specified url with the specified
* parameters.
*
* @param url
* The web address to post the request to
* @param postParameters
* The parameters to send via the request
* @return The result of the request
* @throws Exception
*/
public static String executeHttpPost(String url,
ArrayList<NameValuePair> postParameters) throws Exception {
BufferedReader in = null;
try {
HttpClient client = getHttpClient();
HttpPost request = new HttpPost(url);
UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(
postParameters);
request.setEntity(formEntity);
HttpResponse response = client.execute(request);
in = new BufferedReader(new InputStreamReader(response.getEntity()
.getContent()));
StringBuffer sb = new StringBuffer("");
String line = "";
String NL = System.getProperty("line.separator");
while ((line = in.readLine()) != null) {
sb.append(line + NL);
}
in.close();
String result = sb.toString();
return result;
} finally {
if (in != null) {
try {
in.close();
} catch (IOException e) {
Log.e("log_tag", "Error converting result " + e.toString());
e.printStackTrace();
}
}
}
}
}

我试着解决这里是我的代码。
首先在gradle中添加依赖
编译'com.squareup.okhttp：okhttp：2.6.0'
编译'com.google.code.gson：gson：2.2.4'
<强> Parser.java
<?php

并致电 Parser.java
