jQuery发布调用导致“无法加载资源:net :: ERR_INSUFFICIENT_RESOURCES"； [英] jQuery post calls resulting in "Failed to load resource: net::ERR_INSUFFICIENT_RESOURCES"

问题描述

我有一个页面，允许用户上传和映射CSV文件.完成此操作后，将通过邮寄呼叫将行发送到另一台服务器上的页面.经过将近6,00次呼叫(准确地说是5787次)，我开始收到控制台错误无法加载资源:net :: ERR_INSUFFICIENT_RESOURCES".

I have a page that allows the user to upload and map an CSV file. After that is done, rows are sent through a post call to a page on a different server. After nearly 6,00 calls (5787 to be exactly), I start getting a console error of "Failed to load resource: net::ERR_INSUFFICIENT_RESOURCES".

我尝试运行CSV文件中包含100行的页面，但效果很好...但是当我尝试大型列表(超过10,000行)时，页面冻结了.

I've tried running the page with 100 rows in the CSV file, and it worked just fine... but when I tried a large list (over 10,000 row) it froze up.

以下是进行帖子调用的代码:

Here's the code making the post calls:

for (var i = 0; i < manifestRows.length; i++)
{
    $.post('http://www.otherserver.com/subfolder/handler.php', { tblName: 'foobar', thing1: manifestRows[i][0], thing2: manifestRows[i][1], thing3: manifestRows[i][2], thing4: manifestRows[i][3], thing5: manifestRows[i][4], thing6: manifestRows[i][5], thing7: manifestRows[i][6], thing8: manifestRows[i][7], thing9: manifestRows[i][8], thing10: manifestRows[i][9], thing11: manifestRows[i][10], thing12: manifestRows[i][11], thing13: manifestRows[i][12], thing14: manifestRows[i][13], thing15: manifestRows[i][14], thing16: manifestRows[i][15], thing17: manifestRows[i][16], thing18: manifestRows[i][17] }, function(data) {
    if (data.length == 0)
    {
        var currentProcessing = $('#processingCurrent').html();
        $('#processingCurrent').html(parseInt(currentProcessing) + 1);
        var progress = Math.ceil((parseInt(currentProcessing) / manifestRows.length) * 100);
        if (progress == 99)
            progress = 100;
        progress = progress + '%'
        $("#progressBar").width(progress).html(progress);
        if (progress == '100%')
        {
            $('#processdingDiv').hide();
            $('#allDone').show();
        }
    }
    else
        alert(data);
    });
}

是否可以在用户端或另一台服务器上放置一些代码，以防止发生此资源不足错误?

Is there some code I can put in either the user end, or on the other server to prevent this Insuffiecient Resource error from occuring?

推荐答案

我在AngularJS应用中遇到了几乎完全相同的错误.我要做的是批量处理请求.批次号是相对于您的实例的，但是我一次使用了1,000个呼叫.

I had almost the exact same error in an AngularJS app. What I had to do is batch the requests. The batch number is relative to your instance, but I used 1,000 calls at a time.

由于很多这种情况都是异步发生的，因此我不得不创建两个变量. httpRequestsExpected应该与批处理大小相同，具体取决于您的代码.在我的系统中，每次调用$http.$get();以获得确切值时，我都会对其递增.

Since a lot of this happens asynchronously, I had to create two variables. httpRequestsExpected should be same as batch size, depending on your code. In mine, I just incremented it every time I called $http.$get(); to get the exact value.

var batchSize = 1000;
var httpRequestsExpected;
var httpRequestsMade = 0;

var batchSize = 1000;
var httpRequestsExpected;
var httpRequestsMade = 0;

然后在http 成功和错误功能中，递增httpRequestMade.

Then in the http success and error functions, increment httpRequestMade.

要解决一个批次问题，并且由于http有时会挂起，我无法进行完全匹配，例如:
if(httpRequestsMade === httpRequestsExpected)
但必须这样填充:
if(httpRequestsMade >== httpRequestsExpected - (httpRequestsExpected *0.01))

To resolve a batch, and because http sometimes hangs, I couldn't do an exact match like:
if(httpRequestsMade === httpRequestsExpected)
but had to put in padding like this:
if(httpRequestsMade >== httpRequestsExpected - (httpRequestsExpected *0.01))

然后开始下一个批处理，将开始指针增加batchSize并重置变量.这样就为进程完成过程提供了安全的缓冲时间，而又不会浪费所有资源.

Then start the next batch, incrementing your starting pointer by batchSize and reset the variables. That provides a safe amount of buffering and time for the process to finish without consuming all the resources.
