Node Unirest Request.strictSSL(false) 不适用于 .attach()

如何解决Node Unirest Request.strictSSL(false) 不适用于 .attach()

我能够在我的 RTC 本地主机服务器 https（自签名证书）中进行身份验证并获取一些工作项，在 unirest Request.strictSSL(false) 上设置，但是当我尝试 .attach() 时，它不起作用:

代码：

var cookies = unirest.jar();
async.waterfall([
    (callback) => {
        var req = unirest("POST","https://localhost:9443/ccm/j_security_check")
            .headers({
                "Content-Type": "application/x-www-form-urlencoded",})
            .strictSSL(false)
            .jar(cookies)
            .send("j_username=samuel")
            .send("j_password=samuel")
            .end(function(res) {
                if (res.error) throw new Error(res.error);
                console.log('logged');
                callback();
            });
    },(callback) => {
        var req = unirest("GET","https://localhost:9443/ccm/resource/itemName/com.ibm.team.workitem.WorkItem/2")
            .headers({
                Accept: "application/json",})
            .jar(cookies)
            .strictSSL(false)
            .end(function(res) {
                if (res.error) throw new Error(res.error);
                console.log(res.raw_body);
                callback();
            });
    },(callback) => {
        var req = unirest(
                "POST","https://localhost:9443/ccm/service/com.ibm.team.workitem.service.internal.rest.IAttachmentRestService?projectId=_Jv0jwFXOEeuKc9Bmrq6cOA&multiple=true"
            )
            .strictSSL(false)
            .jar(cookies)
            .attach(
                "file","https://url_to_img"
            )
            .end(function(res) {
                if (res.error) {
                    console.error(res.error);
                } else {
                    console.log('attach worked');
                }
            });
    }
])

输出：

logged
{...workitem}
{ Error: self signed certificate
    at TLSSocket.onConnectSecure (_tls_wrap.js:1058:34)
    at TLSSocket.emit (events.js:198:13)
    at TLSSocket._finishInit (_tls_wrap.js:636:8) code: 'DEPTH_ZERO_SELF_SIGNED_CERT' }

我能够使用 Postman 上传文件，将配置“SSL 证书验证”设置为关闭。 那么我在 unirest 上缺少什么？
