如何设置HttpRequest的路径和查询参数?

Question

我正在对期望字符串作为路径参数的服务进行REST调用，我应该如何传递字符串?

我代码:

HttpClient client = HttpClient.newHttpClient();
HttpRequest request = new HttpRquest.newBuilder().uri(URI.create(endpoint)).GET.header("Content-Type","application/json").build();
HttpResponse<String> response = client.send(request,Httpresponse.BodyHandlers.ofString());
ObjectMapper objectMapper = new ObjectMapper();
MyClass myClass = new MyClass();
myClass = objectMapper.readValue(response.body.toString(),MyClass.class);

对于端点，我应该添加字符串myString作为路径参数。感谢大家的支持!

Answer 1

URIBuilder uri = new URIBuilder().setScheme("https").setHost("dog.com");
List<String> pathSegs = new ArrayList<>();
pathSegs.add("random");
pathSegs.add("path");
pathSegs.add("5");
uri.setPathSegments(pathSegs);
System.out.println(uri.build());

控制台输出:https://dog.com/random/path/5

Answer 2

使用基于apache HTTP API的HTTP -request非常简单。

final HttpRequest httpRequest = HttpRequestBuilder.create(
ClientBuilder.create().build();
)
.build();
MyClass myClass = httpRequest.target(endpoint)
.addParameter(paramKey1, paramValue1)
.addParameter(paramKey2, paramValue2)
.addHeader("Content-Type","application/json")
.get(MyClass.class);
