我在Stack Overflow上看过其他类似的问题,但到目前为止还没有为我做过任何事情。
我有一个角色应用服务http://localhost:4200。 我在http://localhost:8080/myApp/
有一个后端我正试图通过以下电话设置从我的前端到达后端:
public getPeople(): Observable<PeopleModel[]> {
return this.http
.post(API_URL + '/getPeopleDetails', {})
.map(response => {
const people = response.json();
console.log(people);
return partners.map((people) => new PeopleModel(people));
})
.catch(this.handleError);
}
API_URL设置为http://localhost:8080/myApp
我的代理配置如下所示:
{
"/myApp/*": {
"target": "http://localhost:8080/myApp",
"secure": false,
"changeOrigin": true,
"logLevel": "debug",
"pathRewrite" : {"^/myApp" : "http://localhost:8080/myApp"}
}
}
我的package.json有以下内容:
"start": "ng serve --proxy-conf proxy.conf.json",
我在尝试运行应用程序时收到的错误是CORS和403.
Failed to load http://localhost:8080/myApp/getPeopleDetails: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access. The response had HTTP status code 403.
我很感激任何帮助。谢谢!
答案 0 :(得分:1)
在与package.json文件并行的应用程序的根目录下,创建一个新文件
proxy.config.json
{
"name":"xyz",
"version":"1.0.0",
"license":"MIT",
"angular-cli": {},
"scripts": {
"start":"ng serve --proxy-config proxy.config.json",
"test":"ng test"
}
现在在脚本中的 package.json :{}中,将以下带有文件名 proxy.config.json 的flax添加到 start“
{{1}}
}
希望这适合你。
