@CrossOrigin(origins = "http://localhost:4200")
@RequestMapping(method = RequestMethod.GET, value = "/getuser/{username}")
public User getUser(@PathVariable String username) {
restTemplate = new RestTemplate();
headers = new HttpHeaders();
headers.set("User-Agent", "profile-analyzer");
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
ResponseEntity<User> user = restTemplate.exchange("https://api.github.com/users/"+ username +
"?client_id=" + client_id + "&client_secret=" + client_secret,
HttpMethod.GET, entity, User.class);
return user.getBody();
}
我在这里尝试做的(上面的代码)是从Github API获取一些数据并且它工作正常,我也可以将数据提供给Angular(在端口4200上运行)。
@CrossOrigin(origins = "http://localhost:4200")
@RequestMapping(method = RequestMethod.GET, value = "/getrepo/{username}")
public Object getRepository(@PathVariable String username) {
restTemplate = new RestTemplate();
headers = new HttpHeaders();
headers.set("User-Agent", "profile-analyzer");
HttpEntity<String> entity = new HttpEntity<>("parameters", headers);
ResponseEntity<Object> repository = restTemplate.exchange("https://api.github.com/users/"+ username +
"/repos" + "?client_id=" + client_id + "&client_secret=" + client_secret,
HttpMethod.GET, entity, Object.class);
return repository;
}
但是当我这样做时(上面的代码),在同一个控制器中,当我尝试从Angular服务器(端口4200)访问数据时,我的浏览器会说出类似的内容。
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:8080/getrepo/dasunpubudumal. (Reason: CORS header ‘Access-Control-Allow-Origin’ does not match ‘(null)’).
我所做的是我刚刚更改了Github的端点,我试图从中消耗数据。
但是,当我直接访问spring的端点(http://localhost:8080/getrepo/dasunpubudumal)时,它会给出预期的响应。
我该如何纠正?
谢谢。

有这个工作。显然getRepository()
函数不需要交叉原点注释。
