使用AJAX请求OAuth2令牌

Question

我正在尝试使用AJAX来请求令牌。这只会在localhost上用于发出请求。我有代码：

$.ajax({
  url: "TOKEN URL HERE",
  beforeSend: function(xhr) {
    xhr.setRequestHeader("grant_type", "client_credentials");
    xhr.setRequestHeader("client_id", "ENTER CLIENT ID");
    xhr.setRequestHeader("client_secret", "ENTER CLIENT SECRET");
    xhr.setRequestHeader("Content-Type", "application/json");
    xhr.setRequestHeader("Accept", "application/json");
  },
  dataType: "json",
  //content-Type: "application/json",
  type: "POST",
  success: function(response) {
    token = response.access_token;
    expiresIn = response.expires_in;
  },
  error: function(errorThrown) {
    alert(errorThrown.error);
  }
});

但是，它不起作用。这是正确的方法还是我的参数不正确？ （或者是使用AJAX / JQuery / JS无法实现的OAuth2令牌请求）

Answer 1

确定，grant_type，client_id，client_secret应该通过标头而不是有效负载传递？

尝试从标题中删除它们（左接受，仅限内容类型），然后使用其余参数添加“data”属性。

像这样的东西：

$.ajax({
    url: "TOKEN URL HERE",
    beforeSend: function(xhr) {
        xhr.setRequestHeader("Content-Type", "application/json");
        xhr.setRequestHeader("Accept", "application/json");
    },
    dataType: "json",
    data: {
        client_id: "ENTER CLIENT ID",
        client_secret: "ENTER CLIENT SECRET",
        grant_type: "client_credentials"
    },
    type: "POST",
    success: function(response) {
        token = response.access_token;
        expiresIn = response.expires_in;
    },
    error: function(errorThrown) {
        alert(errorThrown.error);
    }
});
