如何处理大量的AJAX请求(> 1000)

我的应用正在从客户端的Google联系人API提取用户的所有Google联系人.这通常会导致1-2000个不同的JSON对象.接收到这些内容后，我的应用程序将对其进行遍历，重新格式化每个联系人对象，然后尝试通过POST请求将重新格式化后的联系人对象保存到我的数据库中.这样做的结果是在客户端触发了大量(1-2000)AJAX调用，但是在5-10个调用之后它们停止了.处理所有这些AJAX请求或一次保存如此大量数据的最佳方法是什么?

My app is fetching all of a User's Google Contacts from the Google Contacts API on the client side. This usually results in between 1 - 2000 different JSON objects. When those are received, my app iterates through them, reformats each Contact Object, and then attempts to save the reformatted Contact Object to my database via a POST request. The result of this is a large number ( 1 - 2000 ) of AJAX calls firing on the Client Side, but they stall out after 5-10 of them. What is the best way to handle all of these AJAX requests, or saving such a large amount of data all at once?

这是我当前代码的摘要版本:

Here is a summarized version of my current code:

// gContacts.length = 722

$(gContacts).each(function(index, contact) {

         // Reformat each contact object to fit into my database
         var newContact = {}
         newContact.title = // String
         newContact.emails = // Object featuring different emails
         newContact.phone_numbers = // Object featuring different phonenumbers

         // Save to Database via Backbone
                    var newContact = new App.Collections.Contacts()
                    newContact.create({
                        title           : newContact.title,
                        emails          : newContact.emails,
                        phone_numbers   : newContact.phone_numbers
                    }, {
                        success: function (response) {

                        },
                        error: function (model, xhr) {
                            var errors = $.parseJSON(xhr.responseText).errors
                            console.log(errors)
                        }
                    }) // End .save
}); // End of .each()
