Question

这是我对API的POST请求

ResponseEntity<String> result = rt.exchange(url, HttpMethod.POST, httpEntity, String.class);

我得到的答复如下

{
    "headers": {
        "Cache-Control": [
            "no-store"
        ],
        "Content-Type": [
            "application/json;charset=UTF-8"
        ],
        "Date": [
            "Thu, 20 Jun 2019 12:50:08 GMT"
        ],
        "Pragma": [
            "no-cache"
        ],
        "Server": [
            "val"
        ],
        "X-Content-Type-Options": [
            "nosniff"
        ],
        "X-Frame-Options": [
            "DENY"
        ],
        "X-Xss-Protection": [
            "1; mode=block"
        ],
        "Content-Length": [
            "331"
        ]
    },
    "body": {
        "access_token": "token_value,
        "scope": "KYC",
        "token_type": "bearer",
        "expires_in": 49900,
        "jti": "jti_val"
    },
    "statusCode": "OK",
    "statusCodeValue": 200
}

我需要提取 access_token，scope，token_type，statusCodeValue

所以我的POJO类的结构应该如何映射响应？或者如何从JSON中获取这些字段的值？

ResponseEntity<PojoClass> result = rt.exchange(url, HttpMethod.POST, httpEntity, PojoClass.class);

Answer 1

尝试一下：更新

 ResponseEntity<Response> response = rt.exchange(url, HttpMethod.POST, httpEntity, Response.class);

类定义：

身体类别：

public class Body implements Serializable{
    private String access_token;
    private String scope;
    private String token_type;
    private long expires_in;
    private String jti;

    //standard getters and setters

}

响应类别：

@JsonIgnoreProperties(ignoreUnknown = true)
public class Response implements Serializable{
    private String statusCode;
    private int statusCodeValue;
    private Body body;

    //standard getters and setters

}

现在：您应该使用它们各自的getters方法访问所需的值。喜欢：

String token=response.getBody.getAccessToken();
String statusCode= respnse.getStatusCode();

Answer 2

正文可以通过上面发布的代码段获取，并且可以使用“ response.getStatus（）”来检索状态代码

使用Rest Template交换方法将Json映射到POJO类
