Question

我的请求如下：-

http://example.com:8984/service/response?q=bags&source=desktop.search&city.data=mumbai|delhi

如何从url访问这些值，以便获得以下地图：-

{
q => bags,
source => desktop.search,
city.data => [mumbai, delhi]
}

我写了下面的程序：-

import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class serviceController {

    @RequestMapping("/service/response")

    String getSearchString(@RequestParam Map<String, String> params) {
        return "SearchString ---- "+params;
    }
}

当我在city.data = mumbai中仅给出1个参数时，它工作正常但是当我给city.data = mumbai | delhi

时遇到错误

请提出正确的方法？预先感谢

Answer 1

我建议您以其他方式发送参数，但是如果需要管道字符，则应将其替换为代码%7C。因此，如果要添加city.data=mumbai|delhi作为参数，则应将其替换为city.data=mumbai%7Cdelhi。

之后，您可以使用String方法解析该字段中的参数。

Answer 2

我认为您可以尝试这样。

@RequestMapping(value = "/test")
@ResponseBody
public void test(@RequestParam Map<String,String> param) {
    String[] city = org.springframework.util.StringUtils.split(param.get("city.data"), "|");
    System.out.println(Arrays.toString(city));
    System.out.println(param);
}

如果只有几个参数，也可以这样尝试。但是请求url应该这样改变。 test2？q = bags＆source = desktop.search＆city.data = mumbai＆city.data = delhi

@RequestMapping(value = "/test2")
@ResponseBody
public void test2(String q, String source, @RequestParam(value = "city.data") String[] city) {
    System.out.println(Arrays.toString(city));
    System.out.println(source);
    System.out.println(q);
}
