在 Postman 中将类对象作为参数传递

Question

我正在开发一个 API 应用程序，但是我在使用特定方法时遇到了困难。

getCertificationPOJO 方法，负责将 Store 作为参数，并搜索该 Store 是否存在于数据库中。

现在这里的问题是如何在 Postman 中将 Store 对象作为参数传递。我尝试将其作为 JSON 字符串传递，但这不起作用。

抱歉编辑不当

@Controller
public class CertController {

    @Autowired
    private CertificationRepository certRepo;
    @Autowired
    private StoreRepository StoreRepository;

    
    @GetMapping(value = "/getCertObject")
    public @ResponseBody
    Optional<Certification> getCertificationPOJO(@RequestParam Store store)
    {return Lists.newArrayList(certRepo.findAll()).stream().filter(e->e.getStore() == store).findFirst();}

}

Answer 1

在这种情况下，您不使用 Params 部分。你使用Body。单击该选项卡并将您的 JSON OBJECT 放入将出现的文本框中。您还需要通过在显示在附件图像右侧最远的 COMBO 中选择适当的值来将 CONTENT TYPE 设置为 JSON。

看看这个：

Answer 2

如果您使用的是 queryParams，则必须单独传递每个键/参数，在您的 Postman 中您可以像这样填写：

key: id          value: 1
key: name        value "asdasd"
key: phoneNumber value: "000"

(...)

另一种选择是您更改策略并在 Body 中传递整个 json，但您必须更改 RestController 以接收 @RequestBody 而不是 @RequestParam

Answer 3

我建议不要在 GET 请求中发送正文，请参阅类似的答案 here

@Murilo 建议的查询参数路由是一种方式，但如果确定数据库中是否已存在 getCertificationPOJO 的方式仅取决于 id，那么您可能只需要发送 id 在这种情况下路径变量将是最好如下所示，其中 {id} 可以替换为实际 ID

GET /getCertObject/{id}

然后在控制器中

@GetMapping("/getCertObject/{id}")
@ResponseBody
Optional<Certification> getCertificationPOJO(@PathVariable String id) {
  ...
}
