我期待以下代码执行Ajax调用。但是，我看到405错误，说

  

请求的资源不支持http方法＆＃39; GET＆＃39;。

如果我使用类型=＆＃39; json＆＃39; 我会

以下是我的内容脚本代码的相关部分

                                console.log(parsedText);


                                var bazExtract = extractEmails1(parsedText);
                                if(bazExtract !== null) {

                                }
                            });
                        }
                    },
                    error: function(err) {
                        console.log(err);
                    }
                });
            });
            //console.log(imgSrcArr);
        });

注意：内容脚本代码的其他部分正在按预期运行，但是没有服务器响应（在开发人员控制台中）到Ajax请求。

如果这是一个CORS问题，是否有针对此类错误的解决方法？我在SO上尝试了一些关于类似问题的答案，但是我无法继续推进其中任何一个问题。

API的documentation中的标题“Post Parameters”表明您应该执行POST，而不是GET。也就是说，使用：type: POST
