Upon receiving the back end coming period img tag
Naive to think so on the line.
<div className={styles.content_img} > {this.props.myCode} </div>
The results did not expect when I received this img he has become a string of emm
So the page is become so. . . . .
Then I found this document on react
dangerouslySetInnerHTML
https://zh-hans.reactjs.org/docs/dom-elements.html
<div className={styles.content_img} dangerouslySetInnerHTML={{ __html: this.props.myCode}}>
</div>
Perfect solution, ha ha ha.
