不能执行看似简单的对openweathermap.org的HTTP POST
不能执行看似简单的对openweathermap.org的HTTP POST
提问于 2018-05-25 05:22:49
我在一个Angular服务组件中的函数，用openweathermap.org发布一个创建新气象站的请求：
registerStation(registerWeatherStation: RegisterWeatherStation): Observable<Response> {
let params = JSON.stringify(registerWeatherStation)
console.log("params: ",params)
let header = new Headers({'Content-Type': 'application/json; charset=utf-8'})
let options = new RequestOptions({ headers: header })
let url = this.servUrl + 'stations?appid=' + this.weatherAppId
return this
.http
.post(url, params, options)
}这来自Chrome的开发人员工具网络选项卡，显示了由上述函数触发的活动。我认为这显示了我的印前检查请求、来自openweathermap.org的印前检查响应和我的请求标头：
Preflight Request???
request url: http://api.openweathermap.org/data/3.0/stations?appid=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Content-Type: application/json
Cache-Control: no-cache

{"external_id":"Paula's_Ranch_1","name":"Paula's Ranch Weather","latitude":xx.155012,"longitude":-xxx.976649,"altitude":100}我做错了什么？我应该从我的后台执行post吗？

将我的POST和GET请求移动到服务器端代码解决了这个问题。我还使用了restsharp.netcore。干净而简单。
