WireMock映射JSON配置求助：响应展示请求头及自定义内容

Hey there! Let's fix your WireMock mapping issues and get it working exactly how you want.

1. Display Multiple/All Request Headers in the Response #

Right now, your mapping only pulls the first value of the msisdn header. To include additional headers (or all headers), you have two straightforward options:

Option A: Show Specific Headers #

If you want to explicitly include specific headers (like msisdn and another one, say user-agent), you can concatenate them in the response body. For plain text output:

{
  "request": {
    "urlPath": "/templated"
  },
  "response": {
    "body": "MSISDN: {{request.headers.msisdn.[0]}}\nUser-Agent: {{request.headers.user-agent.[0]}}",
    "transformers": ["response-template"]
  }
}

For structured JSON output (make sure to set the Content-Type header):

{
  "request": {
    "urlPath": "/templated"
  },
  "response": {
    "body": "{\"msisdn\": \"{{request.headers.msisdn.[0]}}\", \"userAgent\": \"{{request.headers.user-agent.[0]}}\"}",
    "headers": {
      "Content-Type": "application/json"
    },
    "transformers": ["response-template"]
  }
}

Option B: Show All Request Headers #

To dump all incoming request headers as a JSON object, use the {{request.headers}} variable directly:

{
  "request": {
    "urlPath": "/templated"
  },
  "response": {
    "body": "{{request.headers}}",
    "headers": {
      "Content-Type": "application/json"
    },
    "transformers": ["response-template"]
  }
}

2. Add Custom Values/Text to the Response Body #

Absolutely! You can mix static custom text, hardcoded values, and even other WireMock template variables right into the response body. Here are a few practical examples:

Example 1: Static Custom Text + Headers #

{
  "request": {
    "urlPath": "/templated"
  },
  "response": {
    "body": "Hello! Your MSISDN is {{request.headers.msisdn.[0]}}\nThis is a custom message just for you.",
    "transformers": ["response-template"]
  }
}

Example 2: Custom JSON with Headers + Static Fields #

{
  "request": {
    "urlPath": "/templated"
  },
  "response": {
    "body": "{\"status\": \"success\", \"msisdn\": \"{{request.headers.msisdn.[0]}}\", \"customId\": \"98765\", \"message\": \"Request processed successfully\"}",
    "headers": {
      "Content-Type": "application/json"
    },
    "transformers": ["response-template"]
  }
}

Example 3: Use WireMock's Built-in Template Variables #

You can also leverage dynamic variables like the current timestamp or request URL:

{
  "request": {
    "urlPath": "/templated"
  },
  "response": {
    "body": "Request received at {{now}} for URL {{request.url}}\nYour MSISDN: {{request.headers.msisdn.[0]}}",
    "transformers": ["response-template"]
  }
}

Just remember to keep the response-template transformer enabled—it's what makes all these template substitutions work smoothly.
