引入相关部分

// react-draft-wysiwyg begin
import { EditorState, convertToRaw, ContentState } from 'draft-js';
import { Editor } from 'react-draft-wysiwyg';
import draftToHtml from 'draftjs-to-html';
import htmlToDraft from 'html-to-draftjs';
import 'react-draft-wysiwyg/dist/react-draft-wysiwyg.css'
// react-draft-wysiwyg end

定义相关state

state = {
        showRichText: false, // react-draft-wysiwyg
        editorContent: '', // react-draft-wysiwyg
        editorState: '', // react-draft-wysiwyg
    };

富文本编辑器中用到的方法 

/**
     *
     * @react-draft-wysiwyg begin
     */
    handleClearContent = () => {
        this.setState({
            editorState: ''
        })
    }

    handleGetText = () => {
        this.setState({
            showRichText: true
        })
    }

    onEditorChange = (editorContent) => {
        this.setState({
            editorContent,
        });
    };

    onEditorStateChange = (editorState) => {
        this.setState({
            editorState
        });
    };
    // @react-draft-wysiwyg end

提交时将富文本转换为含html的文本

addModalHandleOk = e => {
        const _this = this;
        this.addModalFormRef.current.validateFields()
            .then(values => {
                console.log(this.state.editorContent);
                const params = {
                    title: values.title,
                    content: draftToHtml(convertToRaw(this.state.editorState.getCurrentContent()))
                };

                axios.post(`http://localhost:5555/api/add_blog`, qs.stringify(params)).then((resp) => {
                    if (resp.ret) {
                        console.log(resp.msg);
                    } else {
                        this.addModalFormRef.current.resetFields();
                        this.setState({
                            addModalVisible: false
                        });
                        this.getData(1, 5);
                    }
                }, (err) => {
                    console.log(err);
                });
            })
            .catch(info => {
                console.log('Validate Failed:', info);
            });
    }

上面部分中

draftToHtml(convertToRaw(this.state.editorState.getCurrentContent()))

这一段代码是关键。

获取文本

/**
     * 显示blog Modal
     */
    handleShowDetailBlog = (id) => {
        axios.get(`http://localhost:5555/api/get_blog_detail?id=${id}`, {}).then((resp) => {

            if (resp.data.ret) {
                this.setState({
                    showBlogModalVisible: true,
                    blogDetail: resp.data.content
                })
            } else {

            }
        }, (err) => {
            console.log(err);
        });
    }

提交文本的Modal

<Modal
                    title="创建"
                    visible={this.state.addModalVisible}
                    width={660}
                    onOk={this.addModalHandleOk}

                    cancelText="取消"
                    maskClosable={false}
                    destroyOnClose={true}
                >
                    <Form {...layout} ref={this.addModalFormRef} name="control-ref" preserve={false}>
                        <Form.Item label="标题" style={{ marginBottom: 0 }}>
                            <Form.Item
                                name="title"
                                style={{ display: 'inline-block', width: 'calc(100% - 8px)', marginRight: 15 }}
                                rules={[
                                    {
                                        required: true,
                                        message: "标题不能为空"
                                    }
                                ]}
                            >
                                <Input />
                            </Form.Item>
                        </Form.Item>
                        <Form.Item label="内容" style={{ marginBottom: 0 }}>
                            <Form.Item
                                name="content"
                                style={{ display: 'inline-block', width: 'calc(100% - 8px)' }}
                                rules={[
                                    {
                                        required: true,
                                        message: "内容不能为空"
                                    }
                                ]}
                            >
                                <Editor
                                    editorState={this.state.editorState}
                                    wrapperClassName="demo-wrapper"
                                    editorClassName="demo-editor"
                                    onEditorStateChange={this.onEditorStateChange}
                                />
                                {/* <TextArea rows={4} /> */}
                            </Form.Item>
                        </Form.Item>
                    </Form>
                </Modal>

 提交后显示返回文本的Modal

<Modal
                    title="详情"
                    visible={this.state.showBlogModalVisible}
                    width={660}
                    onOk={this.handleShowBlogModalHandleOk}
                    onCancel={this.handleShowBlogModalHandleCancel}
                    okText="确定"
                    cancelText="取消"
                    maskClosable={false}
                    destroyOnClose={true}
                    footer={null}
                >

                    <div dangerouslySetInnerHTML={{__html: this.state.blogDetail}} style={{height: 300, overflow: 'auto'}}/>

                </Modal>

其中 

<div dangerouslySetInnerHTML={{__html: this.state.blogDetail}} style={{height: 300, overflow: 'auto'}}/>

 是关键,将html文本转为html标签。
