版本：
1、后端实现跨域（php）
header("Access-Control-Allow-Origin: *");
// // 响应类型
// header('Access-Control-Allow-Methods:POST');
// // 响应头设置
// header('Access-Control-Allow-Headers:x-requested-with, content-type');2、前端跨域
项目目录下新建proxy.config.json文件
proxy.config.json
{
"/api": {
"target": "http://localhost", // php服务路径
"logLevel": "debug",
"changeOrigin": true,
"pathRewrite": {
"^/api": ""
}
}
}package.json

}启动使用 npm start
访问使用 http:localhost:4200/api 就会映射到http:localhost
this.http.post('http://localhost:4200/api', {name: this.name, company: this.company, price: this.price }, {
headers: {
'Content-Type': 'application/json'
}
}).subscribe((res: any) => {
if (res.resultCode == 200) {
}
// 加载成功之后做一些事
}, (err: any) => {
});
