Question

我有以下CURL命令可以正常工作。但是在使用java代码时。我使用的是WSO2 API Manager版本1.9.1

 curl -k -d "grant_type=password&username=test&password=test" -H 
"Authorization: Basic QU01dE04MXFrdzg5ZFNFTjk2Vm0waGgwWnBNYTpzeHcxbko3c2gzdm5NVVlmUDEzVmV1bWtsbTRh, 
Content-Type: application/x-www-form-urlencoded" https://XXXXXX:8243/token

我使用RestTemplate API

开发了以下代码

public class Demo {

    public static void main(String[] args) {
        String url = "https://xxxxxxxx:8243/token";

        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        headers.add("Authorization", "Basic QU01dE04MXFrdzg5ZFNFTjk2Vm0waGgwWnBNYTpzeHcxbko3c2gzdm5NVVlmUDEzVmV1bWtsbTRh");
        headers.add("Content-Type", "application/x-www-form-urlencoded");
        headers.add("data", "grant_type=password&username=mahesh&password=mahesh00");

        String json =" {\"data\":\"grant_type=password&username=test&password=test\"}";
        HttpEntity<String> postEntity = new HttpEntity<String>(json, headers);

        RestTemplate restTemplate = new RestTemplate();
        ResponseEntity<String> response =restTemplate.exchange(url, HttpMethod.POST,postEntity,String.class);

        System.out.println("\nSTATUS : "+ response.getStatusCode()+" "+response.getStatusCode().getReasonPhrase());
        System.out.println("Response :"+ response.getBody());
    }
}

当我在下面执行时，我看到以下错误：

Answer 1

您忘记在java代码中指定端口：

https://192.168.0.102:/token

应该是：

https://192.168.0.102:8243/token

你也忘了隐藏IP，就像你使用curl命令一样，但由于它是一个内部IP，没有理由打扰它，它在你自己的局域网之外没有任何意义。所以我也没有掩盖它。

Answer 2

我正面临类似的问题 -

org.springframework.web.client.ResourceAccessException：I / O错误 POST请求＆＃34; http://hostname:port_number/projectname/inbound/message＆＃34;：连接拒绝：连接嵌套异常是java.net.ConnectException：连接被拒绝：连接

所以，我在application.yml下使用src/main/resources，我将主机值从服务器ip_address更改为localhost ，以便在我的电脑上使用Swagger进行测试，

gui:
  protocol: http
  host: localhost
  port: 8280

希望通过帮助某人获得任何信息。

引起：java.net.ConnectException：连接被拒绝：连接org.springframework.web.client.ResourceAccessException：POST上的I / O错误
