这个问题肯定是重复的,但我需要一个答案而无法找到答案。
我需要将一个Json json对象发送到服务器并检索另一个json。 到目前为止我所尝试的并没有奏效,没有任何反应。
我做错了什么?
要发送的json对象是userCreate
,地址是path
,告诉我你是否真的需要地址和json格式。
解决,最终代码:
Thread x = new Thread(){
public void run(){
Looper.prepare();
DefaultHttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(path);
String result = "";
try {
post.setEntity(new StringEntity(userCreate.toString()));
HttpResponse response = client.execute(post);
HttpEntity entity = response.getEntity();
result = EntityUtils.toString(entity);
Toast.makeText(ctx,"Result: " + result + " response: " + response.getStatusLine().getStatusCode(), 10000).show();
} catch(Exception e) {
e.printStackTrace();
}
Looper.loop();
}
};
x.start();

尝试:
DefaultHttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(url);
post.setEntity(new StringEntity(request.toString(), "utf-8"));
// request is the JSONObject
HttpResponse response = client.execute(post);

这对我有用:
//MainActivity.java
Pass the name-value pair to server .you can get those values using json-array in PHP.
String registerURL="http:10.0.2.2/register.php";
public void registerUser(String email, String password, String mobile)
{
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("tag", register_tag));
params.add(new BasicNameValuePair("email", email));
params.add(new BasicNameValuePair("password", password));
params.add(new BasicNameValuePair("mobile", mobile));
JsonParser.makeHttpRequest(registerURL,"POST",params);
}
//JSONParser.java
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
// function get json from url
// by making HTTP POST or GET method
public static JSONObject makeHttpRequest(String url, String method,
List<NameValuePair> params) {
// Making HTTP request
try {
// check for request method
if (method == "POST") {
// request method is POST
// defaultHttpClient
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") {
// request method is 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 (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 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) {
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
}
// return JSON String
return jObj;
}
}

尝试类似:
DefaultHttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(path);
post.setEntity(new StringEntity(request.toString(), "utf-8"));
HttpResponse response = client.execute(post);
跳这将有所帮助。

这对我有用:
// General query of the website. Takes an object of type Q and returns one of class R.
public static <Q extends JSONObject, R> R query(String urlBase, String op, Q q, Class<R> r) throws IOException {
// Prepare to post.
final HttpPost postRequest = new HttpPost(urlBase + op);
if (q != null) {
// Get it all into a JSON string.
final StringEntity input = new StringEntity(asJSONString(q));
input.setContentType("application/json");
postRequest.setEntity(input);
}
log.debug("> " + urlBase + op + (q == null ? "" : " " + q));
// Post it and wait.
return readResponse(postRequest, HttpClientPool.getClient().execute(postRequest), r);
}
