尝试在 Dialogflow 上使用 webhook 动态给出响应时出现 Webhook 响应错误（206）

Question

我正尝试在 java 中使用 DialogFlow api 执行 google 操作。我正在使用 Webhook 请求对 DialogFlow 中所示操作的响应下图。

当尝试此代码时，它工作正常并给出正确的响应，因为 dialogflow 具有预定义的操作工具。

代码：

@PostMapping("/webhook")
public ResponseEntity payload(RequestBody FulfillmentResponse fulfillmentResponse) {
   log.info(fulfillmentResponse.getQueryResult().getQueryText());
   return ResponseEntity.ok(HttpStatus.OK);
}

但是当我动态给出响应时。它给我一个错误。

代码：

@PostMapping("/webhook")
public ResponseEntity payload(RequestBody FulfillmentResponse fulfillmentResponse) {
    log.info(fulfillmentResponse.getQueryResult().getQueryText());
    return ResponseEntity.ok("{\n" +

我假设您正在使用 Java 构建 JSON 响应。请求从 AoG 发送到 Dialogflow，后者调用您的 webhook。在这种情况下，Dialogflow 将原始 AoG 请求包装成 "originalDetectIntentRequest"，如 https://developers.google.com/actions/build/json/dialogflow-webhook-json

中所述

由于您正在解析 JSON 请求并在您的 webhook 中构建响应，因此您应该参考上面的 URL 了解原始 JSON 协议。

希望对您有所帮助。
