Overview

This node provides three main operations related to PHP serialization and WeChat messaging:

1. PHP Serialization: Converts JSON data into a PHP serialized string. Useful when you need to send or store data in a format compatible with PHP applications.
2. PHP Unserialization: Converts a PHP serialized string back into JSON, optionally extracting a nested field by path. This helps integrate PHP-generated data into workflows that use JSON.
3. WeChat Broadcast: Sends messages (text or image) to a specified WeChat contact or group chat. It supports using an already logged-in WeChat account or logging in dynamically via QR code scanning.

Practical Examples

• Serialize complex JSON objects into PHP serialized strings for API requests to PHP backend systems.
• Unserialize PHP serialized responses from legacy PHP services and extract specific fields for further processing.
• Automate sending notifications or images to WeChat groups or contacts directly from n8n workflows.

Properties

Output

The node outputs an array of JSON objects, one per input item, each containing:

• success: Boolean indicating if the operation succeeded.
• operation: The operation performed (serialize, unserialize, or wechatBroadcast).
• For serialize:
  • result: The PHP serialized string.
  • originalData: The original JSON object parsed from input.
• For unserialize:
  • result: The unserialized data or extracted nested field if extractPath was provided.
  • fullData: The full unserialized object.
• For wechatBroadcast:
  • On success: details about the message sent including type, recipient, and whether a logged-in account was used.
  • On failure: an error message describing what went wrong.

If binary data were involved (e.g., images), it uses a file-box abstraction internally but outputs only JSON status and message info.

Dependencies

• Uses the php-serialize library for PHP serialization/unserialization.
• Uses the wechaty and file-box libraries to interact with WeChat for broadcasting messages.
• Requires a WeChat environment where either:
  • A WeChat account is already logged in globally in the workflow environment, or
  • The user can scan a QR code to log in dynamically during execution.

No explicit external API keys are required, but WeChat login credentials or session must be managed externally or via prior nodes.

Troubleshooting

• Common Issues:

  • Failure to unserialize invalid or malformed PHP serialized strings.
  • JSON parse errors when serializing invalid JSON input.
  • WeChat login timeout if QR code is not scanned within the specified wait time.
  • Unable to find the specified WeChat group or contact by name.
  • Using "useLoggedInAccount" without a logged-in WeChat session available.

• Error Messages and Resolutions:

  • "没有找到已登录的微信账号，请先使用微信登录节点登录": No logged-in WeChat account found; run a WeChat login node first.
  • "扫码登录超时，请扫描二维码登录": Login timed out waiting for QR code scan; increase wait time or scan promptly.
  • "找不到群聊: <name>" or "找不到好友: <name>": The specified recipient does not exist or the name is incorrect; verify recipient names.
  • JSON parsing errors: Ensure the input JSON data is valid and properly formatted.
  • PHP unserialize errors: Confirm the input string is a valid PHP serialized string.
