如何在 Spring WebClient 中一次设置多个标头?

问题描述

我试图为我的休息客户端设置标题，但每次我必须写

I was trying to set headers to my rest client but every time I have to write

webclient.get().uri("blah-blah")
         .header("key1", "value1")
         .header("key2", "value2")...

如何使用 headers() 方法同时设置所有标题?

How can I set all headers at the same time using headers() method?

推荐答案

如果这些标头在每个请求的基础上发生变化，您可以使用:

If those headers change on a per request basis, you can use:

webClient.get().uri("/resource").headers(httpHeaders -> {
    httpHeaders.setX("");
    httpHeaders.setY("");
});

这不会节省太多打字时间；因此，对于不会从一个请求更改为另一个请求的标头，您可以在构建客户端时将它们设置为默认标头:

This doesn't save much typing; so for the headers that don't change from one request to another, you can set those as default headers while building the client:

WebClient webClient = WebClient.builder().defaultHeader("...", "...").build();
WebClient webClient = WebClient.builder().defaultHeaders(httpHeaders -> {
    httpHeaders.setX("");
    httpHeaders.setY("");
}).build();
