当我发送此ajax rquest时：

$.ajax({
            headers : {
                'Accept' : 'application/json',
                'Content-Type' : 'application/json'
            },
            url : 'http://localhost:8080/wutup/venues/12',
            type : 'PATCH',
            data : JSON.stringify({description: "842490812321309213801923 gonzagazors"}),
            success : function(response, textStatus, jqXhr) {
                console.log("Venue Successfully Patched!");
            },
            error : function(jqXHR, textStatus, errorThrown) {
                // log the error to the console
                console.log("The following error occured: " + textStatus, errorThrown);
            },
            complete : function() {
                console.log("Venue Patch Ran");
            }
        });

我收到此错误：

XMLHttpRequest无法加载http：//：// localhost：8080 / wutup / venues / 12。Access-

Control-Allow-Methods不允许使用方法PATCH。

但是，使用curl：

 $ curl -v -H "Accept: application/json" -H "Content-type: application/json" -X PATCH -    d' {"address": "8421 Gonzaga Ave"}'  http://localhost:8080/wutup/venues/12

回答：

该$.ajax方法 确实 支持HTTP PATCH。

您看到的问题是该ajax方法Access-Control-Allow-

Methods在选项预检检查的响应标头中查找PATCH

。您的响应中缺少此标头，或者此标头的值中未包含PATCH方法。无论哪种情况，问题都出在服务器上，而不是客户端代码中。

这是使用Java的示例：

response.addHeader("Access-Control-Allow-Methods", "GET, POST, PATCH, PUT, DELETE");
