我使用以下代码创建了JSON对象：
json = new JSONObject();
try {
json.put("success", true);
JSONObject jCustomer = new JSONObject();
jCustomer.put("LOGICALREF", 0);
jCustomer.put("CODE", "");
EditText definitionText = (EditText) findViewById(R.id.definitionText);
jCustomer.put("DEFINITION_", definitionText.getText().toString());
jCustomer.put("ISPERSCOMP", isPersComp);
EditText taxOrIdNoText = (EditText) findViewById(R.id.taxOrIdNoText);
if (isPersComp == 1){
jCustomer.put("TAXNR", "");
jCustomer.put("TCKNO", taxOrIdNoText.getText().toString());
} else {
jCustomer.put("TAXNR", taxOrIdNoText.getText().toString());
jCustomer.put("TCKNO", "");
}
EditText taxOfficeText = (EditText) findViewById(R.id.taxOfficeText);
String taxOfficeString = taxOfficeText.getText().toString();
if (taxOfficeString.isEmpty() || taxOfficeString == null){
jCustomer.put("TAXOFFICE", "TCKIMLIK");
} else {
jCustomer.put("TAXOFFICE", taxOfficeString);
}
EditText emailText = (EditText) findViewById(R.id.emailText);
jCustomer.put("EMAILADDR", emailText.getText().toString());
EditText address1Text = (EditText) findViewById(R.id.address1Text);
jCustomer.put("ADDR1", address1Text.getText().toString());
EditText address2Text = (EditText) findViewById(R.id.address2Text);
jCustomer.put("ADDR2", address2Text.getText().toString());
jCustomer.put("CITY", cityString);
jCustomer.put("CITYCODE", cityNo);
jCustomer.put("TOWN", townString);
jCustomer.put("TOWNCODE", townNo);
EditText inChargeText = (EditText) findViewById(R.id.inChargeText);
jCustomer.put("INCHARGE", inChargeText.getText().toString());
EditText nameText = (EditText) findViewById(R.id.nameText);
jCustomer.put("NAME", nameText.getText().toString());
EditText surnameText = (EditText) findViewById(R.id.surnameText);
jCustomer.put("SURNAME", surnameText.getText().toString());
EditText phoneNo1Text = (EditText) findViewById(R.id.phoneNo1Text);
jCustomer.put("TELNRS1", phoneNo1Text.getText().toString());
EditText phoneNo2Text = (EditText) findViewById(R.id.phoneNo2Text);
jCustomer.put("TELNRS2", phoneNo2Text.getText().toString());
json.put("data", jCustomer);
new postJSON().execute();
} catch (Exception e){
e.printStackTrace();
}
postJSON是一个扩展AsyncTask的私有类。这是它的代码：
private class postJSON extends AsyncTask<Void, Void, Void>{
ProgressDialog progressDialog;
protected void onPreExecute() {
super.onPreExecute();
progressDialog = new ProgressDialog(NewCustomerInfoActivity.this);
progressDialog.setMessage("Yeni müşteri kaydediliyor. Lütfen bekleyiniz.");
progressDialog.setCancelable(false);
progressDialog.show();
}
@Override
protected Void doInBackground(Void... arg0) {
// Don't know what to do here...
return null;
}
protected void onPostExecute(Void requestResult) {
super.onPostExecute(requestResult);
if (progressDialog.isShowing()) {
progressDialog.dismiss();
}
}
}
现在我必须将它作为正文发布到服务器，我不知道从哪里开始。互联网上的大多数教程都使用我无法添加或找到的库，或者太复杂，我无法理解。我已经创建了一个webRequest函数，但是我使用它来从服务器获取JSON对象并且它可以工作：
public String getJson (String urlAdress, Boolean postRequest){
URL url;
String jString = "";
try {
url = new URL(urlAdress);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setReadTimeout(15001);
connection.setReadTimeout(15001);
connection.setDoInput(true);
if (postRequest){
connection.setRequestMethod("POST");
} else {
connection.setRequestMethod("GET");
}
int requestResponse = connection.getResponseCode();
if (requestResponse == HttpsURLConnection.HTTP_OK){
String line;
BufferedReader buffer = new BufferedReader(new InputStreamReader(connection.getInputStream()));
while ((line = buffer.readLine()) != null){
jString += line;
}
} else {
jString = "";
}
} catch (Exception e){
e.printStackTrace();
return null;
}
return jString;
}
如何将JSON对象作为正文添加到网址并发布？上述功能在发布时是否足够？
添加推荐代码后的编辑（输出流等）：
服务器端的Web服务代码：
@RequestMapping(value = "/newCustomer", method = RequestMethod.POST, headers = "Accept=application/json; charset=utf-8", produces = "application/json")
private ResponseEntity<String> newCustomer (@RequestParam(value = "deviceId") String _deviceId,
@RequestParam(value = "ssid") String _ssid,
@RequestBody String _incomingData, //(value = "incomingData")
HttpServletRequest _request,HttpServletResponse _response){
Object responseMap = null;
boolean response = false;
System.out.println(_incomingData);
服务器的传入数据：
DEVICEID = ec5f501b01c54038＆安培; SSID = QUCGFHA7ILIT3E9O8BHTD5NE4H＆安培;％7B％22success％22％3Atrue％2C％22data％22％3A％7B％22LOGICALREF％22％3A0％2C％22CODE％22％3A％22％22％2C％ 22DEFINITION_％22％3A％22asdasd％22％2C％22ISPERSCOMP％22％3A0％2C％22TAXNR％22％3A％22564564％22％2C％22TCKNO％22％3A％22％22％2C％22TAXOFFICE％22％3A％ 22ghfgh％22％2C％22EMAILADDR％22％3A％22asdasd％22％2C％22ADDR1％22％3A％22asdas％22％2C％22ADDR2％22％3A％22asdasd％22％2C％22CITY％22％3A％22Amasya％ 22％2C％22CITYCODE％22％3A5％2C％22TOWN％22％3A％22Hamam％C3％83％C2％B6z％C3％83％C2％BC％22％2C％22TOWNCODE％22％3A3％2C％22INCHARGE％ 22％3A％22xcvxcb％22％2C％22NAME％22％3A％22xcbxcb％22％2C％22SURNAME％22％3A％22gxcb％22％2C％22TELNRS1％22％3A％22456456％22％2C％22TELNRS2％22％ 3A％225456456％22％7D％7D =
ssId和deviceId不应该作为身体的一部分发送。然而就是这样。
我目前使用的功能：
public String postJson (String urlAdress, Boolean postRequest, JSONObject json){
URL url;
String jString = "";
try {
url = new URL(urlAdress);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setReadTimeout(15001);
connection.setReadTimeout(15001);
connection.setDoInput(true);
if (postRequest){
connection.setRequestMethod("POST");
} else {
connection.setRequestMethod("GET");
}
connection.connect();
OutputStreamWriter request = new OutputStreamWriter(connection.getOutputStream());
request.write(json.toString());
request.flush();
int requestResponse = connection.getResponseCode();
if (requestResponse == HttpsURLConnection.HTTP_OK){
} else {
jString = "";
}
} catch (Exception e){
e.printStackTrace();
return null;
}
return jString;
}
答案 0 :(得分：3)
在connection.setDoOutput(true);下方添加行connection.setDoInput(true);。
然后从outputStream获取HttpURLConnection并在那里写json，如下所示：
OutputStream os = connection.getOutputStream();
os.write(json.toString().getBytes("UTF-8"));
os.close();
答案 1 :(得分：-2)
使用Retrofit，
博客 - https://futurestud.io/tutorials/retrofit-getting-started-and-android-client
图书馆 - http://square.github.io/retrofit
使用POON的POJO类很容易实现。
没有外部库，
试试这个，
public static String POST(Activity context, String connectionURL,
YOURBODYOBJECT mparms) throws Exception {
try {
url = new URL(connectionURL);
connection = (HttpURLConnection) url.openConnection();
connection.setReadTimeout(30000);
connection.setConnectTimeout(30000);
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded"); // Change header for your convience.
connection.setChunkedStreamingMode(0);
connection.setRequestMethod("POST");
connection.connect();
request = new OutputStreamWriter(connection.getOutputStream());
request.write(mparms);// pass your body content
request.flush();
HTTP_RESPONSE_CODE = connection.getResponseCode();
switch (HTTP_RESPONSE_CODE) {
case HttpURLConnection.HTTP_OK:
isr = new InputStreamReader(connection.getInputStream());
reader = new BufferedReader(isr);
sb = new StringBuilder();
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
// response variable.
response = sb.toString();
isr.close();
reader.close();
return response.trim();
case HttpURLConnection.HTTP_UNAUTHORIZED:
return String.valueOf(HTTP_RESPONSE_CODE).trim();
case HttpURLConnection.HTTP_BAD_REQUEST:
isr = new InputStreamReader(connection.getErrorStream());
reader = new BufferedReader(isr);
sb = new StringBuilder();
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
response = sb.toString();
isr.close();
reader.close();
return response.trim();
case HttpURLConnection.HTTP_INTERNAL_ERROR:
isr = new InputStreamReader(connection.getErrorStream());
reader = new BufferedReader(isr);
sb = new StringBuilder();
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
response = sb.toString();
isr.close();
reader.close();
return response.trim();
default:
return response.trim();
}
} catch (Exception e) {
// Error
return e.getMessage();
} finally {
connection.disconnect();
}
}
