Question

我是Ionic 2的新手。我向Spring Rest-api发出了一个http post请求。作为标头，我需要设置'content-type': 'application/json'，但Ionic 2会自动将content-type设置为application/json; charset=UTF-8，这会导致我的REST服务以415状态响应。

这是我的代码：

register(user: User){
    let headers = new Headers();
    headers.append('Content-Type', 'application/json');

    return this.http.post(apiUrl + 'users', user, {headers:headers})
        .then((response: Response) => {
            console.log(response);
            console.log(JSON.stringify(user, null , 2));
            console.log(JSON.stringify(headers, null, 2));
        });
}

以下是我在发布帖子请求时收到的错误：

[00:46:35]  error opening ws message: {"category":"console","type":"log","data":["error:
        ",{"status":415,"url":"**MY_URL**","headers":{"x-android-received-millis":"1512686795738","x-frame-options":"DENY","pragma":"no-cache","content-type":"application/json;charset=UTF-8","x-content-type-options":"nosniff","date":"Thu,

        type 'application/x-www-form-urlencoded;charset=UTF-8' not supported\",\"path\":\"/api/users\"}"}]}

请在错误日志中检查标题对象。我怎样才能只留下'content-type': 'application/json'？

非常感谢！
