如何将自定义数据绑定到Twilio Redirect发起的POST请求

Hey there! I can help you embed your custom string data into the POST request body sent by Twilio's Redirect in your Java code. Here's the breakdown of how to do it:

How it works #

Twilio's Redirect.Builder gives you ways to attach custom POST parameters right alongside Twilio's default request data. You can use either the postParameter() method for single key-value pairs or postParameters() to add multiple pairs at once using a map.

Modified Java Code #

Here’s your original code updated to include custom data:

// Import required classes if you haven't already
import com.twilio.twiml.Redirect;
import com.twilio.twiml.TwiMLException;
import com.twilio.twiml.HttpMethod;
import java.util.HashMap;
import java.util.Map;

// Build the Redirect with custom POST parameters
Map<String, String> customParams = new HashMap<>();
customParams.put("CustomGreeting", "Hi Tea Lady!");
customParams.put("OrderId", "TEA-ORD-007");

Redirect redirect = new Redirect.Builder("https://dcebfc49.ngrok.io/asr/smsToTeaLady")
        .method(HttpMethod.POST)
        .postParameters(customParams) // Add multiple custom parameters in one go
        // Alternatively, add single parameters one by one:
        // .postParameter("SpecialRequest", "Extra sugar please")
        .build();

// Generate the TwiML string if needed
try {
    String twiml = redirect.toXml();
    // Use the generated TwiML as required
} catch (TwiMLException e) {
    e.printStackTrace();
}

Updated Request Body Example #

After adding your custom parameters, the POST request body will include both Twilio’s default fields and your custom data, like this:

Called=%2B94702470749&ToState=&CallerCountry=US&...[default Twilio params]...&CustomGreeting=Hi+Tea+Lady%21&OrderId=TEA-ORD-007

Accessing Custom Data on the Receiving End #

On your target endpoint (https://dcebfc49.ngrok.io/asr/smsToTeaLady), you can fetch the custom data just like any regular POST parameter. For example:

• In a Spring Boot controller:

  @PostMapping("/asr/smsToTeaLady")
  public ResponseEntity<String> handleRedirect(@RequestParam("CustomGreeting") String greeting,
                                               @RequestParam("OrderId") String orderId) {
      // Use the custom data here
      return ResponseEntity.ok("Got your message: " + greeting + ", Order ID: " + orderId);
  }
  

• In a standard Servlet:

  String greeting = request.getParameter("CustomGreeting");
  String orderId = request.getParameter("OrderId");
  

That’s all there is to it! Your custom data will now be included in the POST request body alongside Twilio’s default parameters.
