我为一个 php 文件设置了一个 ajax 帖子,该文件使用 htaccess CORS 来回答一个简单的 html 字符串。扭曲的是,当我使用 xmapp 服务器而不是我的 node.js 服务器时,ajax 帖子将起作用。我还用 2 个不同的目标域对其进行了测试,它们都具有相同的 htaccess 和相同的 php 文件。从 xampp 发送都有效,从 node.js 发送只有一个有效。
错误: XMLHttpRequest:仅支持 GET 方法
Javascript 在 node.js 中运行:
$.ajax({
type: 'POST',
url: Customer[i]['phplink'],
crossDomain: true,
async: true,
data: {
status: 'hello',
cachingtrap: (Math.random())
},
timeout: 4000,
dataType : 'html',
success: function(responseData, textStatus, jqXHR) {
console.log('online:'+Customer[i]['name']);
},
error: function (responseData, textStatus, errorThrown) {
console.log(errorThrown+ +textStatus+" "+responseData);
}
});
