我使用Web客户端发布第三方API，第三方API返回响应如下：

{\n    "RetailTransactionGenericResponse": {\n        "authID": 1146185,\n        "product": {\n            "amount": 20,\n            "balance": 0,\n            "status": "D",\n            "metafields": {\n                "metafield": [\n                    {\n                        "name": "serialNum",\n                        "value": 8095843490\n                    }\n                ]\n            }\n        },\n        "responseCode": 0,\n        "responseText": "Success",\n        "transactionID": "b0924cca-f2a9-477f-915b-9153e74ebce0"\n    }\n}\n

所以在我的payload包中，它有RetailTransactionGenericResponseWrapper类，其中包含RetailTransactionGenericResponse类。

RetailTransactionGenericResponse这是类的代码

import com.fasterxml.jackson.annotation.JsonCreator;\nimport com.fasterxml.jackson.annotation.JsonInclude;\nimport com.fasterxml.jackson.annotation.JsonProperty;\nimport lombok.AllArgsConstructor;\nimport lombok.Builder;\nimport lombok.Data;\nimport lombok.ToString;\n\n@Data\n@ToString\n@Builder\n@AllArgsConstructor(onConstructor_ = @JsonCreator)\n@JsonInclude(JsonInclude.Include.NON_NULL)\npublic class RetailTransactionGenericResponse {\n\n    @JsonProperty\n    private String authID;\n\n    @JsonProperty\n    private Product product;\n\n    @JsonProperty\n    private String responseCode;\n\n    @JsonProperty\n    private String responseText;\n\n    @JsonProperty\n    private String transactionID;\n}\n …

我有我的 Angular 2 项目试图获取用户的当前位置，因此在我的班级中我有以下代码：

export class CurrentLocation {
  constructor(private http: Http) { }
  private lat : any;
  private lon : any;
  private params  = new URLSearchParams();
  private url = 'api/search/location';


  getPosition = (lat, lon) => {
    navigator.geolocation.getCurrentPosition((position) => { 
      this.lat = position.coords.latitude; 
      this.lon = position.coords.longitude;
     });
  }
  getCurrentLocation(): Observable<any> {
    this.getPosition(this.lat, this.lon);
    console.log(this.lat+ "," + this.lon);
    //console.log(this.lat + ":" + this.lon);
    this.params.set('lat', this.lat);
    this.params.set('lon', this.lon);
    //console.log(this.params.toString());
    var result = this.http.get(this.url, { search: this.params });
    result.toPromise();
    return result;
  }
}
