Chrome新版本73.0.3683.75的Ajax调用错误？ [英] Ajax call bug with Chrome new version 73.0.3683.75?

问题描述

在更新Chrome之前，我的代码运行正常。

My code was working fine before the Chrome update.

我对服务器进行了ajax调用。我的服务器收到呼叫，将JSON返回给客户端，但是答案始终为空。当我查看Fiddler时，会从服务器得到答复。

I make an ajax call to my server. My server receives the call, returns JSON to the client, but the answer is always empty. When I look in Fiddler I get an answer from the server.

我尝试使用JQuery，也尝试使用xmlhttp调用。总是相同的结果

I try with JQuery, and I also try with an xmlhttp call. Always the same result

是否应用了新的CORS策略规则？？

Did new CORS policy rules apply...?

有我的xmlHTTP调用

There is my xmlHTTP call

 var xmlhttp = new XMLHttpRequest();   // new HttpRequest instance 
      var theUrl = "URL";
      xmlhttp.open("POST", theUrl);
      xmlhttp.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
      xmlhttp.send('{ "args" :{ "Obj":"my obj"}}');
      xmlhttp.onreadystatechange = function(state,xhh,aaa){
        if (xmlhttp.readyState == XMLHttpRequest.DONE) {
          alert(xmlhttp.responseText);
        }
      }

ajax调用类似

$.ajax({
        url: "URL",
        data: '{ "args" :{ "Obj":"my obj"}}',
        dataType: "json",
        contentType: "application/json; charset=utf-8",
        type: "POST",
        async: false,       
        error: function (xhr, ajaxOptions, thrownError) {
          if (that.Fail != null) {
            that.Fail();
          }
        },
        success : function(data){

           alert(data);

        }
      })

推荐答案

升级到Chrome 73后，我遇到了同样的问题。感谢@wOxxOm

I had the same problem after upgrade to Chrome 73. Thanks to @wOxxOm

这是到目前为止的解决方法：

This is the workaround until now:

1. 转到chrome：// flags


2. 禁用启用网络服务

1. Go to chrome://flags
2. Disabled the Enable network service

更新：

根据此公告，这不是错误： https://www.chromium.org/Home/chromium- security / extension-content-script-fetches

This is not a bug, according to this announcement: https://www.chromium.org/Home/chromium-security/extension-content-script-fetches

您需要将跨域提取放置到背景脚本中，而不是内容脚本中。

You will need to put the Cross-Origin Fetches to the background script instead of the content script.
