所以我知道这个问题经常被问到,但是我正在尝试检索在promise中创建的变量。我在这里看到的示例涉及到调用.then并在那里使用数据,但是我想做的事情涉及一个异步函数-我不能在.then块中使用。
这是我的代码。我正在使用Asana API调出到期的任务列表。成功记录。但是我想将最后一个块中的列表值另存为变量,以便在其他地方使用。
const asana = require('asana');
const client = asana.Client.create().useAccessToken("xxx");
client.users.me()
.then(user => {
const userId = user.id;
// The user's "default" workspace is the first one in the list, though
// any user can have multiple workspaces so you can't always assume this
// is the one you want to work with.
const workspaceId = user.workspaces[0].id;
return client.tasks.findAll({
assignee: userId,
workspace: workspaceId,
completed_since: 'now',
opt_fields: 'id,name,assignee_status,completed'
});
})
.then(response => {
// There may be more pages of data, we could stream or return a promise
// to request those here - for now, let's just return the first page
// of items.
return response.data;
})
.filter(task => {
return task.assignee_status === 'today' ||
task.assignee_status === 'new';
})
.then(list => {
console.log (util.inspect(list, {
colors: true,
depth: null
}));
})
.catch(e => {
console.log(e);
});

如果您愿意以异步/等待的方式重写.then(),那么这样的方法可能对您有用:
const fetch = require('node-fetch');
async function doit() {
const response = await fetch('https://jsonplaceholder.typicode.com/todos/1');
const json = await response.json();
console.log(json);
}
doit();
