本文介绍了我如何强制大量呼叫同步运行?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我希望下面的呼叫电话一个接一个同步运行。但他们不遵循订单。



运行序列节点模块在这里没有帮助,因为我没有试图在系列中运行gulp任务(即它的语法类似于 gulp.task(mytask,[foo, (baz)] 等),而是在系列中咕噜咕噜打电话,如下所示。

  gulp.task(dostuff,function(callback){

gulp
.src(...)
.pipe(gulp。 dest(...);

gulp
.src(...)
.pipe(gulp.dest(...);

gulp
.src(...)
.pipe(gulp.dest(...);

callback() ;
});

如何让它们一个接一个地运行? > async 作为呼叫的控制流,以便让他们只进行一项任务,同时避免您获得金字塔e所以像这样的东西应该对你的用例有好处:

  var async = require('async'); 

gulp.task('yeah',function(cb){
async.series([
function(next){
gulp.src('.. '')
.pipe(gulp.dest('...')
.on('end',next);
},
function(next){
gulp.src('...')
.pipe(gulp.dest('...')
.on('end',next);
},
函数(下一个){
gulp.src('...')
.pipe(gulp.dest('...')
.on('end' ,下一个);
}
],cb);
});

这也可以让你有一些错误处理,并更好地发生问题的地方。


I want the gulp calls below to run synchronously, one after the other. But they do not follow an order.

The run-sequence node module doesn't help here, as I'm not trying to run gulp tasks in series (i.e. it has syntax similar to gulp.task("mytask", ["foo", "bar", "baz"] etc.), but rather gulp "calls" in series, as you see below.

gulp.task("dostuff", function (callback) {

  gulp
    .src("...")
    .pipe(gulp.dest("...");

  gulp
    .src("...")
    .pipe(gulp.dest("...");

  gulp
    .src("...")
    .pipe(gulp.dest("...");

  callback();
});

How do I make them run one after the other?

解决方案

You can use async as a control flow for your calls to get them in only one task, also avoiding you to get a "pyramid effect". So something like this should be good for your use-case:

var async = require('async');

gulp.task('yeah', function (cb) {
  async.series([
    function (next) {
      gulp.src('...')
        .pipe(gulp.dest('...')
        .on('end', next);
    },
    function (next) {
      gulp.src('...')
        .pipe(gulp.dest('...')
        .on('end', next);
    },
    function (next) {
      gulp.src('...')
        .pipe(gulp.dest('...')
        .on('end', next);
    }
  ], cb);
});

That will also allow you to have some error handling and target better where a problem occured.
