问答 nutz rest HttpPost

nutz rest post 是不是必须使用 http://127.0.0.1/test/info/select/{"version", "NutzTest","website", Nutz.version()} 这种形式传参。

我用下面方式后台参数是index.html

Map<String, Object> parms = new HashMap<String, Object>();
    parms.put("version", "NutzTest");
    parms.put("website", Nutz.version());
String response = Http.post("http://127.0.0.1/test/info/select/", paramlist, 5 * 1000);

http://127.0.0.1/test/info/select/{"version", "NutzTest","website", Nutz.version()}

不知所云

http包就是对HttpConnection的封装，没有"必须"怎么怎么传参一说

把json直接拼入url是违反http规范的

@At("/jgxx/info")
public class test {
	@AdaptBy(type = JsonAdaptor.class)
	@At("/select/**")
	@POST
	public String getUser(@Param("..") NutMap jgxx) {
		// TODO 这里是实现代码
		System.out.println("jgxx"+jgxx);
		JSONObject json = new JSONObject();
		json.put("code", 200);
		json.put("message", "请求成功!");
		json.put("data", "");
		return json.toString();
	}
}

请求代码

Map<String, Object> parms = new HashMap<String, Object>();
    parms.put("version", "NutzTest");
    parms.put("website", Nutz.version());
String response = Http.post("http://127.0.0.1/test/info/select/", paramlist, 5 * 1000);

这样做可以获取到参数

String response = Http.post("http://127.0.0.1/test/info/select/{"version", "NutzTest","website", Nutz.version()} ", "", 5 * 1000);

你写的代码就不合法,

  1. Http.post的params参数是一个Map, 传字符串会编译错误的
  2. Http.post发的参数是表单, 后端用JsonAdaptor接收当然会报错
  3. @At("/select/**") 会优先匹配路径参数, 所以方法的第一个参数就用路径参数来填充
  4. 你用Http.post在路径里面填json字符串, 只是歪打正着地用一个错误的方式调用一个错误的方法,碰巧得到一个正确的输出

这样写才是你要的东西:

Http.post3("http://127.0.0.1/test/info/select", Json.toJson(params), Header.create().asJsonContentType(), 5 * 1000);

@At("/select")
