我已经使用了大约5种方法将JSON数据发布到HTTP请求URL但它没有得到很好的结果，它没有发布我想要的JSON格式，以下是我想要发送的JSON以及我当前成功发送它使用HTML：
这是我想要的JSON： { “×”： “N”， “Y”： “55”}
这是我成功运作的HTML代码：
<html><head><script>
function sendForm(form)
{
// Construct the JSON string in form.value
// x is a string ('cos of the quotes)
// y is an integer ('cos of no quotes)
form.value.value = "{ \"x\": \"" + form.example1.value + "\", \"y\": " + form.example2.value + " }"
form.submit();
}
</script></head>
<body>
<form action="https://api.winv.com/v1/4bhj/306adk" method="post">
<input type="hidden" name="value">
string:<input type="text" name="example1">
number:<input type="text" name="example2">
<input type="button" value="Submit" onClick="sendForm(this.form);">
</form>
</body>
</html>
我试过的代码（这是所有功能）
public void xyz() {
try {
JSONObject json = new JSONObject();
json.put("x", "Nishant");
json.put("y", 34567);
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams,
10000);
HttpConnectionParams.setSoTimeout(httpParams, 10000);
HttpClient client = new DefaultHttpClient(httpParams);
//
//String url = "http://10.0.2.2:8080/sample1/webservice2.php?" +
// "json={\"UserName\":1,\"FullName\":2}";
String url = "url";
HttpPost request = new HttpPost(url);
request.setEntity(new ByteArrayEntity(json.toString().getBytes(
"UTF8")));
request.setHeader("json", json.toString());
HttpResponse response = client.execute(request);
HttpEntity entity = response.getEntity();
// If the response does not enclose an entity, there is no need
} catch (Throwable t) {
Toast.makeText(this, "Request failed: " + t.toString(),
Toast.LENGTH_LONG).show();
}
}
public void getServerData() throws JSONException, ClientProtocolException,
IOException {
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, 10000);
HttpConnectionParams.setSoTimeout(httpParams, 10000);
HttpClient client = new DefaultHttpClient(httpParams);
HttpPost request = new HttpPost(
"url"); // add
// your

request.setHeader("Content-Type", "application/json");

json.put("y", "55");
json.put("x", "Nishant");
Log.i("jason Object", json.toString());
StringEntity se = new StringEntity(json.toString());
se.setContentEncoding("UTF-8");
se.setContentType("application/json");
request.setEntity(se);
HttpResponse response = client.execute(request);
HttpEntity entity = response.getEntity();
InputStream is = entity.getContent();
String _response = convertStreamToString(is);
System.out.println("res-- " + _response);
// Check if server response is valid code
int res_code = response.getStatusLine().getStatusCode();
System.out.println("code-- " + res_code);
}
private static String convertStreamToString(InputStream is) {
BufferedReader reader = new BufferedReader(new InputStreamReader(is),
8192);
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append((line + "\n"));
}
} catch (IOException e) {
e.printStackTrace();
} finally {

}
return sb.toString();
}
public void postData() {
// Create a new HttpClient and Post Header

try {

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("", "Nishant"));
nameValuePairs.add(new BasicNameValuePair("x:", "45"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
}
protected void sendJson(final String email, final int pwd) {
Thread t = new Thread() {
public void run() {
Looper.prepare(); // For Preparing Message Pool for the child
// Thread
HttpClient client = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(client.getParams(),
10000); // Timeout Limit
HttpResponse response;
JSONObject json = new JSONObject();
try {
HttpPost post = new HttpPost(
"url");
json.put("x", email);
json.put("y", pwd);
StringEntity se = new StringEntity(json.toString());
se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE,
"application/json"));
post.setEntity(se);
response = client.execute(post);
/* Checking response */
if (response != null) {
InputStream in = response.getEntity().getContent(); // Get
// the
// data
// in
// the
// entity
}
} catch (Exception e) {
e.printStackTrace();
// createDialog("Error", "Cannot Estabilish Connection");
}
Looper.loop(); // Loop in the message queue
}
};
请告诉我为什么不发布？哪里可能做错了？

看起来像很多代码。我认为你可以更好地将JSON对象封装在一个单独的方法中，然后可能使用下面的例子，这对我来说非常有用。您似乎有很多我认为不必要的HTTP连接对象......
public static boolean sendJSONtoBLX(String path, JSONObject json)
throws Exception {
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httpost = new HttpPost(path);
StringEntity se = new StringEntity(json.toString());
httpost.setEntity(se);
httpost.setHeader("Accept", "application/json");
httpost.setHeader("Content-type", "application/json");
@SuppressWarnings("rawtypes")
ResponseHandler responseHandler = new BasicResponseHandler();
@SuppressWarnings("unchecked")
String response = httpclient.execute(httpost, responseHandler);
JSONObject jsonResponse = new JSONObject(response);
String serverResponse = jsonResponse.getString("success");
if (serverResponse.equals("true")) {
return true;
} else {
return false;
}
}
我正在创建JSON对象：
public final static JSONObject writeJSON() throws Exception {
JSONObject obj = new JSONObject();
try {
obj.put("x", "Nishant");
obj.put("y", 34567);
} catch (JSONException e) {
e.printStackTrace();
}
return obj;
}
新信息：在本地测试后，看来这是Android无法访问https的SSL问题。与JSON等无关。上述答案适用于普通的http。

只需将此代码放入您的代码中：
StringEntity oStringEntity = new StringEntity( json.toString());
oStringEntity.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
request.setEntity(oStringEntity);
而不是：
request.setEntity(new ByteArrayEntity(json.toString().getBytes("UTF8")));
request.setHeader("json", json.toString());
如果这解决了你的问题，那么请接受它！
