api – HTTPS请求仅在iOS,Ionic 2上失败

我有一个Ionic 2应用程序,它调用 Spring Boot API将推送通知发送到其他设备. API使用HTTPS配置.

API POST请求适用于除iOS之外的所有内容.

我在服务器上的SSL证书是自签名的(可能就是这样吗？).

适用于：

>离子服务
> Android
>邮差
>卷曲

这是请求：

public sendNotificationRequest(title: string,action: string,name: string,tokens: any,notifications: boolean) {
    // Check if user turned off notifications
    if(!notifications) {
        return;
    }

    let headers = new Headers({'Content-Type': 'application/json'});
    headers.append('Authorization','Basic ' + btoa(this.username_decrypted + ':' + this.password_decrypted));
    let body = this.formObj(tokens,title,action,name);
    console.log(body);

    this.http.post("https://<some-url>",body,{ headers: headers }
    ).subscribe((response) => {
        console.log("HTTPS RESPONSE");
        console.log(response);
    },function(error) {
        console.log("HTTPS ERROR");
        console.log(error);
    });
}

标题响应如下：

response.setHeader("Access-Control-Allow-Origin","*");
response.setHeader("Access-Control-Allow-Methods","POST,GET,OPTIONS,DELETE");
response.setHeader("Access-Control-Max-Age","3600");
response.setHeader("Access-Control-Allow-Headers","Origin,X-Requested-With,Content-Type,Accept,Authorization");

并收到此错误：

{
 "_body":
    {"isTrusted":true},"status":0,"ok":false,"statusText":"","headers":{},"type":3,"url":null
}

Spring Boot API：

@CrossOrigin
@RequestMapping(value="/notifications",method=RequestMethod.POST,consumes=MediaType.APPLICATION_JSON_VALUE,produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<NotificationParent> sendNotifications(@RequestBody NotificationParent objs) {
    ...
    return new ResponseEntity<NotificationParent>(objs,HttpStatus.OK);
}

我假设它有iOS安全问题,但我不知道.
