javax.ws.rs.ProcessingException：找不到内容类型application / x-www-form-urlencoded类型的writer

我在 MediaType.APPLICATION_FORM_URLENCODED_TYPE 中使用"resteasy-client"库发送POST请求 .

示例代码：

String serviceUrl = "URL";

    ConnectRequest connectRequest = new ConnectRequest();
    connectRequest.setUsername("");
    connectRequest.setPassword("");
    connectRequest.setScope("bearer");
    connectRequest.setGrant_type("");

    Entity<ConnectRequest> entity = Entity.entity(connectRequest,
                MediaType.APPLICATION_FORM_URLENCODED_TYPE);

    ResteasyClient client = new ResteasyClientBuilder().build();
    ResteasyWebTarget target = client.target(serviceUrl);

    Response response = target.request().post(entity);

    System.out.println("RESP : "+response.toString());

请求使用POSTMAN时，连接正常并发送正确的响应

但在请求使用该程序后，它会产生错误

回应：

javax.ws.rs.ProcessingException：找不到内容类型application / x-www-form-urlencoded类型的writer

请帮忙...

java maven web-services jax-rs resteasy

    您不能使用POJO发送 application/x-www-form-urlencoded . 您需要使用javax.ws.rs.core.Form类 .

    Form connectRequest = new Form()
    .param("username", "...")
    .param("password", "...")
    .param("client_id")
    ...;

    您也可以使用 Entity.form(connectionRequest) ，这是速记，因此您不必使用 MediaType.APPLICATION_FORM_URLENCODED_TYPE .

    另外，请参阅this also以解析响应 . 你不需要依赖 . 你已经有了RESTEasy的那个 .
