Question

我有一些奇怪的问题，在AJAX使用POST方法调用MVC期间，它会在服务器上的第二次/第三次调用后随机返回400 BAD Request，但在本地系统中它可以正常工作。

我在每个调用期间都传递了相同的参数，但随机它会在服务器上返回400 error。

以下是我的AJAX来电代码：

function RunSimulation() {
ShowProgress();
var url = GetDomainURL() + "/Project/RunSimulation";
var data = $("form").serialize();
var random = Math.random();
alert('multipart/form-data;charset=UTF-8; boundary='+random);
$.ajax({
    url: url,
    type: 'POST',
    data: data,
async: false,
cache: false,
    contentType: 'multipart/form-data;charset=UTF-8; boundary='+random,
    // timeout: 60000 * 10,
    success: function (data) {
        alert('sucess');
        HideProgress();
    },
    error: function (jqXHR, textStatus, errorThrown) {
        HideProgress();
    }
});
}

我在过去2天内遇到过这个问题，所以如果有人对此有任何想法，请帮助我。

Answer 1

评论中暗示了这一点，但为什么要设置Content-Type来使用multipart/form-data？您没有发送multipart/form-data，而是发送application/x-www-form-urlencoded数据。没有“多部分”附件，因此不需要边界。

尝试完全删除ajax调用中的contentType行; Content-Type默认为application/x-www-form-urlencoded，这就是所需要的。

此外，更好地使用async: true否则您的页面会在阻止等待响应ajax请求时无响应 - 除非这是您想要的。

我不确定这是400个错误请求错误的原因，但至少这消除了一种可能性。

Answer 2

我根据你在AJAX Call

期间的建议使用下面的代码

function RunSimulation() {
ShowProgress();
var url = GetDomainURL() + "/Project/RunSimulation";
var data = $("form").serialize();
var random = Math.random();    
$.ajax({
    url: url,
    type: 'POST',
    data: data,
async: true,
cache: false,       
    // timeout: 60000 * 10,
    success: function (data) {
        alert('sucess');
        HideProgress();
    },
    error: function (jqXHR, textStatus, errorThrown) {
        HideProgress();
    }
});

}

但仍然会出现如下所示的错误
