Question

我的ajax帖子向我的Heroku应用程序发出的请求在大约90％的通话中丢失了其发布数据。

出于安全原因，我正在使用GET并更改为POST。 GET请求已经工作了几个月。 POST请求在IDE中本地工作，并使用工头。但是当它移动到我的Heroku应用程序时，POST数据会在90％的调用中丢失。

我非常确定数据是否正确发送：

在本地运行我的应用程序时可以使用
使用Chrome开发工具我验证数据是否是通话的一部分

我将详细的传入请求数据转储到Papertrail日志。在这里，我可以看到数据消失了。内容长度表明请求数据应该在那里，但它已经消失了。

我正在使用的Ajax调用。我尝试过$ .post请求和非jquery ajax请求。我已尝试使用JSON.stringify对数据和许多不同的请求标头组合。

 function doPostRequestWithDataV2(method, data) {
    var methodName = "/call/echo";
    var jqxhr = $.ajax({
        type: "POST",
        contentType: "application/json;charset=utf-8",
        url: methodName,
        data: {uuuuu: "ppppp"},
    })
            .done(function () {
                var jsonString = jqxhr.responseText;
                alert("All went well: " + jsonString);
            })
            .error(function () {
                alert("Problem: " + jqxhr.responseText);
            });
}

完全输出成功通话。粗体的重要区别。

Answer 1

EHH。我找到了自己问题的答案。我发现Heroku的路由层在发送标头后会暂停。所以我所要做的就是在读完所有字节后再添加2毫秒的休眠，然后从套接字再次读取。现在它完美无缺。

对Heroku的Ajax POST请求丢失了发布数据
