Scene: The user number after public attention to the user a reply message
Results are as follows:
Interactive and user-generated number to achieve specific public action can be achieved in two ways:
1. Passive reply to the user message
2. Service News
These two different? Passive reply to the message server is essentially a micro letter sent me a reply message. Therefore, developers need to respond within 5 seconds otherwise it will prompt " The number of public service is temporarily unavailable " message and the customer service is an interface when in fact no guarantee that within five seconds of response time for the micro-channel server can respond first "success" then call customer service to send messages asynchronously send a message
Note: Customer Service is limiting the number of messages! ! ! Specific permission to see the interface at the number of push and developers receive micro-channel services in 48 within hours can call the Customer Service Interface
Send a message needs customer service number to check the public if there is customer service Message permission to view customer permission can view the message in the last number of public micro-channel interfaces permission console, as shown below:
Attached below the passive message reply message and code call message here passive duplication processing without making
Passive message reply
1. The configuration message, for example, a text message
2. Response message that is sent to the message server WeChat
Enumeration class defines a message type
package com.net.wx;

When writing tools configuration message fields shown here are two ToUserName FromUserName and data from the server to the micro-channel push server developers of XML fields, so the server in response to the micro-channel message, the sender and recipient can turn
