Question

这是我的代码整洁干净

你可以看到我做了一个for循环并将一个[i]变量传递给了api 现在发生的事情是循环是没有击中api并回到循环。任何解决方案？

 var a = ['a1','a2','a3','a4','a5','a6','a7','a8','a9','a10','a11','a12','a13','a14','a15','a16','a17','a18','a19','a20','a21','a22','a23','a24','a25','a26','a27','a28','a29','a30','a31','a32','a33','a34','a35','a36', 'a37']

 console.log(a)

for(var i = 0; i <= a.length; i++){

          $http({
          url: '/MyApp/getIt?urlofpage=https://www.example.com/alpha/'+a[i]+'.html',
        method: "POST", 
            }).success(function(response){

        console.log(a[i]);
        console.log(response);
           });

}

看起来你正在尝试使用jQuery ajax来调用API。如果是这种情况，您应该使用$.post或$.ajax：

var a = ['a1','a2','a3','a4', ...];
console.log(a);
for(var i = 0; i <= a.length; i++){
  $.ajax({
    url: '/MyApp/getIt?urlofpage=https://www.example.com/alpha/'+a[i]+'.html',
    method: "POST", 
    success: function(response) {
      console.log(a[i]);
      console.log(response);
    }
  });
}

否则，请分享$http功能。

您不能将for循环用于数据库调用，因为它是异步的。请查看以下代码。

var a = ['a1','a2','a3','a4', ...];

  var i=0;
checkArrayLength();
function checkArrayLength(){
    if(i<a.length){
        makeRequest(a[i]);
    }
}

    function makeRequest(param1){

        $.ajax({
            url: '/MyApp/getIt?urlofpage=https://www.example.com/alpha/'+param1+'.html',
            method: "POST", 
            success: function(response) {
              console.log(a[i]);
              i=i+1;
              console.log(response);
                checkArrayLength();
            },
            error:function(response) {
              console.log(a[i]);
              i=i+1;
              console.log(response);
                checkArrayLength();
            }
        });

     }

for循环不会调用restful api
