这是我的问题：我正在尝试使用使用在线 T 恤网站 API 的网络 T 恤设计师。这个问题应该与应用程序无关，但它有助于我描述系统。这个设计器是用 javascript 编码的，它向调用 t-shirt 站点 API 的 php 代理发出请求。我在网络服务器上上传了代理和带有脚本的 html，一切正常。

不幸的是，我需要从不同的域加载 html。起初，这会引发同源错误。我通过添加到 php 代理来修复它

header("Access-Control-Allow-Origin: *");

但是，现在以下代码出现了一个新错误

this.getShop = function (shopId) {
    var shop = null;
    $.ajax({
        type: "GET",
        async: false,
        cache: true,
        url: this.createUrl(this.baseHttpUrl + "/shops/" + shopId),
        dataType: "xml",
        crossDomain: true,
        success: function(data) {
            shop = $(data).find("shop");
        },
        error:function(xhr,err,other){
            alert("readyState: "+xhr.readyState+"\nstatus: "+xhr.status+"\nerror: "+err+"\nother: "+other);
            alert("responseText: "+xhr.responseText);
        }
    });
    return shop;
};

我从第一个警报中得到的是

readyState: 4
status: 200
error: parsererror
other: Error: Invalid XML: data

最终的“数据”是一些 XML 数据，与我从 xhr.responseText 获得的数据相同，这似乎正是 T 恤网站应该发送的内容，而且似乎完全有效......我想这仍然与跨域设置。该错误来自 parseXML jQuery 函数，如果我从同一个网络服务器运行所有内容，我相信它甚至不会被调用......

编辑：这是我作为数据获得的示例

服务器<script>端正在向 XML 数据的末尾添加标签。如果可能，请尝试停止正在执行此服务器端的任何操作。

如果这是不可能的，下面应该去掉它：

this.getShop = function (shopId) {
    var shop = null;
    $.ajax({
        type: "GET",
        async: false,
        cache: true,
        url: this.createUrl(this.baseHttpUrl + "/shops/" + shopId),
        dataType: "text",
        crossDomain: true,
        success: function(data) {
            // rough parsing of data
            shop = $.parseXML(data.split("\<\!-- Hosting 24")[0]);
        },
        error:function(xhr,err,other){
            alert("readyState: "+xhr.readyState+"\nstatus: "+xhr.status+"\nerror: "+err+"\nother: "+other);
            alert("responseText: "+xhr.responseText);
        }
    });
    return shop;
};
