Micro-Credit Public account development tutorial (13) text message all Raiders

Introduction and summary of content

Several readers have complained that "Liu Feng only uses text messages as an example, never mention the picture and text message, do not know how to use the message", well, I was wrong, originally thought that the basic API encapsulation, the framework to build, and then give a text message to use the example, we can suit, Perhaps because of my poor painting skills, the picture of the cat is not like the cat bar ...

This article mainly introduces the use of text message in the development of micro-credit public account, as well as several manifestations of the text message. Title named "Text Message", this is definitely not the title party, is to take this opportunity to the text of the message related to the problem, doubts, obstacles to all clear away.

The main parameter description of the picture and text message

Through the micro-letter Official Message Interface guide, you can see the text message parameters, as shown in the following figure:

You can see from the diagram that:

1 The number of text messages is limited to 10, that is, the value of Articlecount in the picture (the number of messages, limited within 10);

2 for multiple text messages, the first picture and text display as a large image, other pictures of the picture displayed as a small map;

3 The first text picture size suggested for 640*320, other pictures and texts of the picture size suggested for 80*80;

Well, to understand these, and combined with the 4th article on the message and Message processing tool encapsulation, want to reply to the text message to the user is not difficult.

Multiple manifestations of a text message

Below directly through the code to illustrate the main five manifestations of the use of text messages, the source code is as follows:
