Zendesk API+Angular:由于CORS[duplicate],无法接收数据

我用的是 Zendesk API HttpClient .

searchZendesk( query : string ) {
    console.log(query)

    this.search( query ).subscribe(
      (data) => console.log(data),
      (err) => console.log(err.error),
      () => console.log("complete")
    )
}

search( query : string ) {
    let headers = this.setOptions()
    let url = `${ this.baseUrl }/search.json?query=${ query }`

    return this.http.get(`${ this.baseUrl }/search.json?query=${ query }`, { headers: headers })
  }

setOptions() {
    let key = this.setKey()
    let headers = new HttpHeaders({
      'Authorization': key,
    })

    return headers
}

searchZendesk()

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8100' is therefore not allowed access.
