yhs0092 commented on issue #1289: cse uri 添加参数如何操作 URL: https://github.com/apache/servicecomb-java-chassis/issues/1289#issuecomment-520421086 假设provider端有这样一个REST接口方法： ```java @RestSchema(schemaId = "hello") @RequestMapping(path = "/provider/v0") public class HelloService { @GetMapping(path = "/testQuery") public String testQuery(@RequestParam("q1") String q1, @RequestParam("q2") String q2) { return q1 + q2; } } ``` 在consumer端，你可以这样调用它： ```java @RestSchema(schemaId = "helloConsumer") @Path("/consumer/v0") public class HelloConsumerService { private RestTemplate restTemplate = RestTemplateBuilder.create(); @Path("/testQuery") @GET public String testQuery() { // 可变长参数，注意与前面的占位符的顺序对应 String response = restTemplate .getForObject( "cse://provider/provider/v0/testQuery?q1={q1}&q2={q2}", String.class, "qqq1", "qqq2"); System.out.println("response1 = " + response); // map参数，key值和占位符里的名字对应 Map<String, String> params = new HashMap<String, String>(); params.put("q1", "ppp2"); params.put("q2", "ppp2"); response = restTemplate.getForObject( "cse://provider/provider/v0/testQuery?q1={q1}&q2={q2}", String.class, params); System.out.println("response2 = " + response); // 或者你可以直接做字符串拼接 response = restTemplate.getForObject( "cse://provider/provider/v0/testQuery?q1=sss1&q2=sss2", String.class); System.out.println("response3 = " + response); return "OK"; } } ``` 或者你也可以去网上搜一搜别的用法，在网上能找到不少RestTemplate的使用资料 : )
