使用 Java Unirest 发布'x-www-form-urlencoded'实体

Question

我使用javaUnirest来调用我的api。但现在我需要发布一个对象，但使用x-www-form-urlencoded，我使用以下代码：

public static void main(String[] args) {
Unirest.config().setObjectMapper(new JacksonObjectMapper());
System.out.println(Unirest
.post("http://192.168.2.157:8082/auth/realms/collatum/protocol/openid-connect/token")
.header("Content-Type", "application/x-www-form-urlencoded")
.body(RequestToken.builder()
.username("user")
.password("1234")
.grant_type("password")
.client_id("front")
.build()).asString().getBody()

);
}

我得到这个错误：

{"错误"："无效请求"，"错误描述"："缺少表单参数：grant_type"}

当我分析请求时，头是可以的：(但看起来对象在json中，没有x-www-form-urlencoded

Answer 1

您的身体似乎处于应用程序/x-www-form-urlencoded的错误形式

它不应该是json对象，而应该是类似grant_type=password&client_id=front&username=user&password=1234的对象

可以在这里找到一个例子
