reactjs 使用异步终级解决方案 async,await实践

async componentDidMount() {
  let t = this;
  console.log(this.props.location);
  t.tree.getPandectView({}, t.state.page, this.state.pageSize);
  await t.getProjectId();
  let searchParams = {
    order: 'asc',
    projectId: t.props.location.query.projectId || this.state.projectId,
    sort: 'contractType',
    contractClass:this.state.contractClass
  };
  t.table.getBaseContracts(searchParams, t.state.page, this.state.pageSize)
}

getProjectId = async function(){
  let t = this;
  await request({url:'/contractBase/pandectView',params:{page:t.state.page, rows:this.state.pageSize}})
    .then(res=>{
      console.log(res);
      this.setState({
        projectId:2312
      })
    })
};
