如何将Twilio设置为phoneNumber，在Spring中将此数字作为用户输入
如何将Twilio设置为phoneNumber，在Spring中将此数字作为用户输入
提问于 2019-07-04 07:14:29
“我正在实现一个注册机制，在我的字段中有一个电话号码的属性。如何使用Twilio向用户在注册过程中输入的电话号码发送一条消息？”
这是在成功创建帐户时发送给用户的Twilio SMS通知。下面是我的代码是如何实现的。
private static final String ACCOUNT_SID = "ACd176f3083e1333d14939fe6f27d90a99";
private static final String AUTH_ID = "4e3327cb4efbe3ecd8e893d809533763";
public void sendSMS() {
try {
User user = new User();
Twilio.init(ACCOUNT_SID, AUTH_ID);
Message.creator(new PhoneNumber(user.getPhoneNumber()), new PhoneNumber("+12029151841"),
"Your account has been created succesfuly.").create();
}
catch (TwilioException e) {
System.out.println("An error occured from twillio."+e.getMessage());
}
}
@PostMapping(value="/registerUser")
public ModelAndView registerUser(@Valid User user, BindingResult bindingResult, ModelAndView modelAndView){
//skipped other is statements for checking possible errors.
else{
//set a user to disabled by default before activation thru email.
user.setEnabled(false);
//save a user in the database.
userService.save(user);
//generating the confirmation token
ConfirmationToken confirmationToken = new ConfirmationToken(user);
confirmationTokenRepository.save(confirmationToken);
//sending the email message
SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
simpleMailMessage.setTo(user.getEmail());
simpleMailMessage.setSubject("Complete your registrations");
simpleMailMessage.setFrom("devkibuchi2018@gmail.com");
simpleMailMessage.setText("To activate your account, please click here : "
+"http://localhost:8080/activate- account?token="+confirmationToken.getConfirmationToken());
emailSenderService.sendEmail(simpleMailMessage);
modelAndView.addObject("Email ", user.getEmail());
//send also an sms message using Twilio.
sendSMS();
modelAndView.setViewName("successfulRegistration");
}
return modelAndView;
}用户输入电话号码的Thymeleaf段。
<form action="#" th:action="@{/registerUser}" th:object="${user}" method="post" >
<div class="form-group">
<label th:for="phoneNumber">Phone Number: </label>
<input class="form-control" th:field="*{phoneNumber}" />
<br>
<label th:for="phoneNumber" th:if="${#fields.hasErrors('email')}" th:errors="*{phoneNumber}" required="required"
class="btn btn-danger">
</label>
</div>
</form>我希望系统能够获取电话号码，并将其设置为phoneNumber。然而，我有这样的错误：
从小到小发生错误。需要一个“到”电话号码。

User user = new User();
Twilio.init(ACCOUNT_SID, AUTH_ID);
Message.creator(new PhoneNumber(user.getPhoneNumber())用户对象具有空phoneNumber，因为您从未在代码中的任何位置设置它。所以您在这里得到了空指针异常，user.getPhoneNumber()。
如果你写得像：
User user = new User();
user.setPhoneNumber("+12541254122");
Twilio.init(ACCOUNT_SID, AUTH_ID);
Message.creator(new PhoneNumber(user.getPhoneNumber()), new PhoneNumber("+12029151841"),
"Your account has been created succesfuly.").create();然后，它应该在没有空指针异常的情况下工作。
下面的代码就行了。
public void sendSMS(User user) {
try {
Twilio.init(ACCOUNT_SID, AUTH_ID);
Message.creator(new PhoneNumber(user.getPhoneNumber()), new PhoneNumber("+12029151841"),
"Your account has been created succesfuly.").create();
}
catch (TwilioException e) {
System.out.println("An error occured from twillio."+e.getMessage());
}
}
@PostMapping(value="/registerUser")
public ModelAndView registerUser(@Valid User user, BindingResult bindingResult, ModelAndView modelAndView){
//skipped other is statements for checking possible errors.
else{
//set a user to disabled by default before activation thru email.
user.setEnabled(false);
//save a user in the database.
userService.save(user);
//generating the confirmation token
ConfirmationToken confirmationToken = new ConfirmationToken(user);
confirmationTokenRepository.save(confirmationToken);
//sending the email message
SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
simpleMailMessage.setTo(user.getEmail());
simpleMailMessage.setSubject("Complete your registrations");
simpleMailMessage.setFrom("devkibuchi2018@gmail.com");
simpleMailMessage.setText("To activate your account, please click here : "
+"http://localhost:8080/activate- account?token="+confirmationToken.getConfirmationToken());
emailSenderService.sendEmail(simpleMailMessage);
modelAndView.addObject("Email ", user.getEmail());
//send also an sms message using Twilio.
sendSMS(user);
modelAndView.setViewName("successfulRegistration");
}
return modelAndView;
