就是将Generator函数和自动执行器,包装在一个函数里
async function fn(args) { // ... } function fn(args) { return spawn(function* () { // ... }) } spawn 函数就是自动执行器 function spawn(genF) { return new Promise(function(resolve, reject) { const gen = genF(); function step(nextF) { let next; try { next = nextF(); } catch(e) { return reject(e); } if(next.done) { return resolve(next.value); } Promise.resolve(next.value).then(function(v) { step(function() { return gen.next(v); }); }, function(e) { step(function() { return gen.throw(e); }); }); } step(function() { return gen.next(undefined); }); }); }
Sorry, something went wrong.
