稍微调整JSON响应后，错误已更改为W/System.err: org.json.JSONException: No value for retCode。

这是我的ActivityRegister.java类：
public class ActivityRegister extends AppCompatActivity implements View.OnClickListener {
Button btnRequestPin, btnConfirm, btnRequestNewPin;
EditText editTextEmail;
EditText editTextPin;
private static final String FIRST_START_KEY = "first_start";
private static final boolean ALWAYS_SEND_FIRST_START_BROADCAST = false;

finish();

this.startActivity(intent);
}
@Override
public void onClick(View v) {
if(v == btnConfirm){
final String email = editTextEmail.getText().toString();
final String token = editTextPin.getText().toString();
if (email == null || email.length() == 0){
Toast.makeText(this,"Email required",Toast.LENGTH_SHORT).show();
return;
}
if (token == null || token.length() == 0){
Toast.makeText(this,"OTP required",Toast.LENGTH_SHORT).show();

String retCode = jsonObject.getString("retCode");
String status = jsonObject.getString("status");
int retCodeInt = Integer.parseInt(retCode);
Net.fastToast(ActivityRegister.this,status);
if (retCodeInt==0) { //Registration success

这是我给的stringResponse：
public void callServiceWithURLPart(final Activity activity, final String urlPart, final String postBody, final ICallServiceResult callServiceResult){
final ProgressDialog progress = new ProgressDialog(activity);
progress.setTitle("Processing..");
progress.setProgressStyle(android.R.attr.progressBarStyleSmall);
//progress.setMessage("Connecting...");
progress.show();
ConnectivityManager connMgr = (ConnectivityManager)
activity.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();
if (networkInfo != null && networkInfo.isConnected()) {
Runnable r = new Runnable() {
@Override
public void run() {
OkHttpClient client = new OkHttpClient.Builder().connectTimeout(60, TimeUnit.SECONDS).build();
try{
String servicePath = kURLBase + urlPart;
Log.d("OkHttpClient","servicePath = "+servicePath);
Log.d("postBody",postBody);
Request request = new Request.Builder()
.url(servicePath)
.put(RequestBody.create(MEDIA_TYPE_JSON, postBody))
.build();
final Response response = client.newCall(request).execute();
if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
//final String stringResponse = response.body().string();
final String stringResponse = "{'serviceName': 'registerToken', 'emailID': '', 'token': ''}";
if(stringResponse!=null){
Log.d("ServiceResponseString",stringResponse);
}else {
Log.d("ServiceResponseString","null");
}
if(callServiceResult!=null){
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
progress.dismiss();
if(stringResponse!=null){
callServiceResult.serviceResult(urlPart,true,stringResponse);
}
else {
callServiceResult.serviceResult(urlPart,false,stringResponse);
}
}
});
}
} catch (Exception e){
Log.d("OkHttpClient exception",e.toString());
final Exception _e = e;
if(callServiceResult!=null){
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
progress.dismiss();
callServiceResult.serviceResult(urlPart,false,_e.toString());
}
});
}
}
}
};
Thread t = new Thread(r);
t.start();
} else {
progress.dismiss();
fastToast(activity,"Connect to internet and try again.");
}
}
我的基本网址是：public static final String kURLBase = "https://api-test.allianz.com/digithonempwebservice/rest";，在提出stringResponse时会提供。
任何帮助将不胜感激。
答案 0 :(得分：2)
试试这个：
String retCode = jsonObject.optString("retCode");
不同之处在于
optString返回空字符串（“”） 您指定的密钥不存在。另一方面getString抛出一个JSONException。如果数据是错误的，请使用getString如果您不确定它是否存在，则丢失或者选择optString。
答案 1 :(得分：1)
正如崩溃日志所示，您正试图从json访问retCode但不在那里。
如果您不确定字段，则应使用optString而不是getString。
答案 2 :(得分：0)
您的JSON中没有retCode
