我有一个Ionic 2应用程序，该应用程序调用Spring BootAPI来向其他设备发送推送通知。该API已配置为HTTPS。

该API POST请求适用于 除以外的 所有内容iOS。

我在服务器上的SSL证书是自签名的（也许就是这样）。

适用于：

• ionic serve
• Android
• Postman
• curl

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);
    });
}

标头响应如下：

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");

并且收到此错误：

{
 "_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);
}

我假设它是一个iOS安全问题，但我不知道。
