如何删除 CORB 警告?

2022-01-15 00:00:00 cors google-chrome jquery javascript cross-origin-read-blocking

Chrome 一直工作到版本 73.现在它向我抛出了一个 CORB 警告并阻止我的 chrome 扩展程序运行.

Chrome was working until version 73. Now it is throwing me a CORB warning and stopping my chrome extension from running.

这是我的ajax jquery代码，没什么特别的

Here is my ajax jquery code, nothing special

  $.ajax({
    url: this.url + "api/users",
    type: 'get',
    data: { account_id: this.account_id(), user_id: this.user_id(), person_id: person_id },
    success: function (data) {
      //do stuff
    }
});

我确实注意到，如果我删除 x-content-type-options 标头以使其不再显示nosniff"，我可以返回一些 Ajax 请求，但不能返回其他请求.不确定这是否意味着什么，但我注意到返回数组的 json 请求有效，但其他请求无效.

I did notice that if I remove the x-content-type-options header so that it no longer reads "nosniff" I can get some Ajax requests to be returned but not others. Not sure if this means anything but I noticed that the json requests that returned an array worked but others did not. 

remove_keys = %w(X-Content-Type-Options)
response.headers.delete_if{|key| remove_keys.include? key}

[{'id' : '123'}] <-worked
{'id' : '123'} <- did not work (not sure if means anything)

来自 chrome 的完全错误

Cross-Origin Read Blocking (CORB) blocked cross-origin response https://ideas.test/api/users?token=W9BDdoiKcXLWSHXWySnwdCV69jz2y&account_id=3098355&user_id=john%40gmail.com&person_id=21046915&sync=false&new=true with MIME type application/json.

如何在不通过 chrome 删除正文的情况下返回响应正文?

How can I get the response body to be returned without chrome removing the body due to CORB?

推荐答案

我找到了解决方法.对某人来说可能是矫枉过正，但我​​花了 15 分钟来解决所有问题.在您的内容脚本中，将所有 ajax 调用包装到一个函数中:

I found a workaround. Might be an overkill for someone, but it took me 15 mins to fix everythiung. In your content script wrap all your ajax calls into a function:

将 ajaxGet 函数添加到您的内容脚本中:

Add ajaxGet function to your content script:

function ajaxGet(data){
    return new Promise(function (resolve, reject) {
        chrome.runtime.sendMessage({action: 'ajaxGet', data: data}, function (response) {
            console.log(response)
            if(response&&!response.statusText){//Might need some work here
                resolve(response);
            } else {
                reject(response)
            }
        });
    });
}

然后在你的 background.js 中添加一个监听器:

And in your background.js add a listener:

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
   if(request.action=="ajaxGet"){
       $.ajax(request.data).then(sendResponse,sendResponse)
       return true //telling chrome to wait till your ajax call resolves
   }
})

代替

$.ajax({
    url: this.url + "api/user_boards",
    type: 'get',
    data: { account_id: this.account_id()}
})

打电话

ajaxGet({
    url: this.url + "api/user_boards",
    type: 'get',
    data: { account_id: this.account_id()}
}).then(onSuccess, onError) //handle response from here

如果你不想在你的 background.js 中使用 jquery，你可以调用 Xhr.像这样的:

If you don't want to use jquery in your background.js you can make Xhr call in stead. Something like this:

var data = JSON.stringify(false);

var xhr = new XMLHttpRequest();
xhr.withCredentials = true;

xhr.addEventListener("readystatechange", function () {
  if (this.readyState === this.DONE) {
    console.log(this.responseText);
    sendResponse(this.responseText)
  } else {
    //handle errors
  }
});

xhr.open("GET", request.data.url);

xhr.send(data);

您必须自己解决标题.
