问题描述

//如何向url发送@RequestParam值

//how to send @RequestParam value to url

enter code here@ApiRestController

公共类 CityController 扩展了 BaseController{

public class CityController extends BaseController{

    @GetMapping("/cities")

    public ResponseEntity<CitiesResponse> getAll(
            @RequestParam(value = "pageNumber", defaultValue = "1") int pageNumber,
            @RequestParam(value = "pageSize", defaultValue = "100") int pageSize,
            @RequestParam(value = "sortBy", defaultValue = "id", required = false) String sortBy,
            @RequestParam(value = "sortDirection", defaultValue = "asc", required = false) String sortDirection,
            @RequestParam(value = "search", required = false) String search) {
        return new ResponseEntity(cityService.getAll(pageNumber, pageSize, sortBy, sortDirection, search), HttpStatus.OK);
    }
}

推荐答案

为了方便地操作 URLs/path/params/等，可以使用 Spring 的 UriComponentsBuilder 类.手动连接字符串更干净，它会为您处理 URL 编码:

To easily manipulate URLs / path / params / etc., you can use Spring's UriComponentsBuilder class. It's cleaner that manually concatenating strings and it takes care of the URL encoding for you:

UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(url)
        .queryParam("pageNumber", 1)
        .queryParam("pageSize", 10)
        .queryParam("sortBy", "id")
        .queryParam("sortDirection", "desc")
        .queryParam("search", "hello search");

HttpEntity<?> entity = new HttpEntity<>(headers); //Update this as per your code

HttpEntity<String> response = restTemplate.exchange(
        builder.build().encode().toUri(), 
        HttpMethod.GET, 
        entity, 
        String.class);
