与Identity Server 4一起使用fetch

当使用资源所有者密码流时,如何使用带有IdentityServer4的fetch来获取JWT令牌?(大多数情况下不建议这样做)。

首先,您可以在这里找到有用的信息来实施您的解决方案:

• http://docs.identityserver.io/en/release/quickstarts/2_resource_owner_passwords.html#requesting-a-token-using-the-password-grant

• https://auth0.com/docs/api-auth/tutorials/password-grant

但是如何使用[fetch api]从IdentityServer 4获取令牌呢?

    const form = new FormData();
    form.append('grant_type', 'password');
    form.append('username', username);
    form.append('password', password);
    if (this._settings.scope) {
        form.append('scope', this._settings.scope);
    }
    form.append('client_id', this._settings.clientId);
    if (this._settings.clientSecret) {
        form.append('client_secret', this._settings.clientSecret);
    }

    var options = {
        method: 'POST',
        headers: {
           'Content-Type': 'multipart/form-data'
        },
        rejectUnauthorized: false, // when use local unverified certificate
        body: form
    };

我应该收到一个JWT令牌作为响应,但我收到了一个http 500错误。“内部服务器错误”

如果我用fiddler跟踪HTTP头,我会得到以下结果:

POST http://127.0.0.1:8888/ HTTP/1.1
content-type: multipart/form-data
accept-encoding: gzip,deflate
user-agent: node-fetch/1.0 (+https://github.com/bitinn/node-fetch)
