Java Apache HttpClient 4.x不支持的媒体类型

java cookies

Java Apache HttpClient 4.x不支持的媒体类型,java,cookies,apache-httpclient-4.x,Java,Cookies,Apache Httpclient 4.x,我一直在尝试从HTTPPOST请求获取cookie，该请求用于使用用户名和密码在特定RESTAPI上进行身份验证。问题在于cookie存储中没有cookie（所有相关的隐藏参数都是正确的）。用于验证用户（JSON）的POST方法的主体是： { “用户名”：， “密码”： } 我正在使用以下代码： public static void main(String[] args) { String USER_AUTHENTICATION = "/user/authentication

我一直在尝试从HTTPPOST请求获取cookie，该请求用于使用用户名和密码在特定RESTAPI上进行身份验证。问题在于cookie存储中没有cookie（所有相关的隐藏参数都是正确的）。用于验证用户（JSON）的POST方法的主体是：

{
“用户名”：，
“密码”：
}
我正在使用以下代码：

    public static void main(String[] args) {

    String USER_AUTHENTICATION = "/user/authentication";
    String baseUrl = "http://<someIP>/<someProjectName>/rest";

    HttpClient http = null;
    CookieStore httpCookieStore = new BasicCookieStore();
    RequestConfig globalConfig = RequestConfig.custom().setCookieSpec(CookieSpecs.STANDARD).build();
    CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
    credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("<someUsername>", "<somePassword>"));

    HttpClientBuilder builder = HttpClientBuilder.create().setDefaultCookieStore(httpCookieStore)
            .setDefaultRequestConfig(globalConfig).setDefaultCredentialsProvider(credentialsProvider);
    http = builder.build();

    HttpPost httpRequest = new HttpPost(baseUrl + USER_AUTHENTICATION);
    HttpResponse httpResponse;
    try {
        httpResponse = http.execute(httpRequest);
    } catch (Throwable error) {
        throw new RuntimeException(error);
    }

    List<Cookie> cookies = httpCookieStore.getCookies();
    System.out.println("Cookies! " + cookies);
}

publicstaticvoidmain（字符串[]args）{
字符串USER_AUTHENTICATION=“/USER/AUTHENTICATION”；
字符串baseUrl=”http:////rest";
HttpClient http=null；
CookieStore httpCookieStore=新的BasicCookieStore（）；
RequestConfig globalConfig=RequestConfig.custom（）.setCookieSpec（CookieSpecs.STANDARD.build（）；
CredentialsProvider CredentialsProvider=新的BasicCredentialsProvider（）；
setCredentials（AuthScope.ANY，新用户名密码凭据（“，”）；
HttpClientBuilder=HttpClientBuilder.create（）.setDefaultCookieStore（httpCookieStore）
.setDefaultRequestConfig（globalConfig）.setDefaultCredentialsProvider（credentialsProvider）；
http=builder.build（）；
HttpPost httpRequest=新的HttpPost（baseUrl+用户认证）；
HttpResponse HttpResponse；
试一试{
httpResponse=http.execute（httpRequest）；
}捕获（可丢弃错误）{
抛出新的运行时异常（错误）；
}
List cookies=httpCookieStore.getCookies（）；
System.out.println（“Cookies！”+Cookies）；
}
控制台输出为：

12:09:34.406[main]DEBUG org.apache.http.wire-http-outing-0第一件突出的事情是
POST//rest/user/authentication http/1.1
具有
内容长度：0
您确定要发送数据吗

服务器还以415响应，这可能是因为您正在发送
内容类型：text/plain；charset=UTF-8
，您可能应该发送
application/json；字符集=UTF-8
。您可能还希望将Accept头设置为
application/json
，告诉服务器您希望响应是json


如果您只调用基于JSON的RESTAPI，那么直接使用HTTP客户机的级别似乎很低。就我个人而言，我会使用Springs RestTemplate（也可以配置为使用HttpClient和连接池），代码将缩短5倍，并且更易于阅读
 您应该更改问题的标题，它与cookies无关
和
httpPost.setHeader（“内容类型”、“应用程序/json”）
，但是当我看到您的示例时，我得到了
org.apache.http.headers-http-outgoing-0，看起来您是从其他地方复制的。您有CredentialsProvider，这通常用于基本身份验证，如果需要向服务发布用户/传递，则可能不应使用它。此外，您几乎从不在REST服务中使用Cookie，通常对身份验证的调用会返回一个令牌，您必须将该令牌添加到未来的请求中。对我来说，这听起来像是在你的头上。除非你能提供一个可以从互联网上访问的REST服务版本，否则我想我帮不了你。你有关于端点的文档吗？那么也许我可以构建一个虚拟应用程序
