等待所有诺言解决

当所有链条都解决后，我希望所有人解决。

当然，然后将每个链的承诺传递给

all()

$q.all([one.promise, two.promise, three.promise]).then(function() {    console.log("ALL INITIAL PROMISES RESOLVED");});var onechain   = one.promise.then(success).then(success),    twochain   = two.promise.then(success),    threechain = three.promise.then(success).then(success).then(success);$q.all([onechain, twochain, threechain]).then(function() {    console.log("ALL PROMISES RESOLVED");});
