如何从浏览器 javascript 访问 thingsboard REST API？

Question

我是 thingsboard 的新手，我有一个 thingsboard 服务器。我正在尝试访问 thingsboard REST API 并以 CORS 错误结束，因为 OPTIONS 请求返回 401.

这是我的 thingsboard.yml，默认情况下似乎支持“*”

spring.mvc.cors:
  mappings:
    # Intercept path
     "/api/auth/**":
        #Comma-separated list of origins to allow. '*' allows all origins. When not set,CORS support is disabled.
        allowed-origins: "*"
        #Comma-separated list of methods to allow. '*' allows all methods.
        allowed-methods: "POST,GET,OPTIONS"
        #Comma-separated list of headers to allow in a request. '*' allows all headers.
        allowed-headers: "*"
        #How long, in seconds, the response from a pre-flight request can be cached by clients.
        max-age: "1800"
        #Set whether credentials are supported. When not set, credentials are not supported.
        allow-credentials: "true"

我检查了这个问题 Thingsboard No 'Access-Control-Allow-Origin' header is present on the requested resource. angularjs 但我不清楚如何禁用评论中的 OPTIONS 身份验证。我尝试了 link 中的代码，但得到的是 401。

var url = "http://THINGSBOARDURL:PORT/api/customer/d8f7b410-5480-11e9-bc30-bd0cca1006d3/assets?limit=10";

  var xhr = createCORSRequest('GET', url);
  if (!xhr) {
    alert('CORS not supported');
    return;
  }

  // Response handlers.
  xhr.onload = function() {
    var text = xhr.responseText;
    console.log(text);
  };

  xhr.onerror = function() {
    alert('Woops, there was an error making the request.');
  };

xhr.setRequestHeader("Accept", "application/json")
xhr.setRequestHeader("X-Authorization","Bearer JWTTOKEN")
xhr.send();

对“http://URL:PORT/api/customer/d8f7b410-5480-11e9-bc30-bd0cca1006d3/assets?limit=10' from origin 'http://localhost:8100”处的 XMLHttpRequest 的访问已被 CORS 策略阻止：对预检请求的响应未通过访问控制检查：'Access-Control-Allow-Origin' header 不存在于请求的资源。请帮忙

这是我的错误。 xmlhttprequest 使用的 api 是 /api/customer/.. 等，但 CORS 仅对 /api/auth/** 和 /api/v1/** 启用它以某种方式错过了我的通知。

我将 thingsboard.yml CORS 部分路径从 /api/v1/** 更改为 /api/**，现在错误没有发生。
