获取 JWS 令牌正在使用 curl 但不适用于 Java

Question

这是我用 curl 做的：

curl -d "username=<user>&password=<pass>" -X POST https://example.com/wp-json/api/v1/token

这很有效，我收到了令牌。这是 curl 发送的内容：

POST https://example.com/wp-json/api/v1/token HTTP/1.1
Host: example.com
User-Agent: curl/7.55.1
Accept: */*
Content-Length: <length>
Content-Type: application/x-www-form-urlencoded

username=<user>&password=<pass>

Java 我收到代码 403。这是 HttpClient 的调试输出：

org.apache.http.wire - http-outgoing-0 >> "POST /wp-json/api/v1/token HTTP/1.1[\r][\n]"
org.apache.http.wire - http-outgoing-0 >> "Content-Length: 45[\r][\n]"
org.apache.http.wire - http-outgoing-0 >> "Content-Type: application/x-www-form-urlencoded; charset=ISO-8859-1[\r][\n]"
org.apache.http.wire - http-outgoing-0 >> "Host: www.example.com[\r][\n]"
org.apache.http.wire - http-outgoing-0 >> "Connection: Keep-Alive[\r][\n]"
org.apache.http.wire - http-outgoing-0 >> "User-Agent: Apache-HttpClient/4.5.13 (Java/1.8.0_121)[\r][\n]"
org.apache.http.wire - http-outgoing-0 >> "Accept-Encoding: gzip,deflate[\r][\n]"
org.apache.http.wire - http-outgoing-0 >> "[\r][\n]"
org.apache.http.wire - http-outgoing-0 >> "username=<user>&password=<pass>"

我在这里看不到 curl 和 java 之间的显着差异。谁知道我在这里做错了什么？

这是我当前的 java 代码：

public void getToken(URI url, String username, String password) {
        HttpEntity entity = new StringEntity("username=" + username + "&password=" + password, ContentType.APPLICATION_FORM_URLENCODED);

        HttpHost target = new HttpHost(url.getHost(), 443, "https");

        SSLContext sslcontext = SSLContexts.createSystemDefault();
        SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(
                sslcontext, new String[] { "TLSv1.2", "SSLv3" }, null,
                SSLConnectionSocketFactory.getDefaultHostnameVerifier());

        Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
                .register("http", PlainConnectionSocketFactory.INSTANCE)
                .register("https", sslConnectionSocketFactory)
                .build();

        PoolingHttpClientConnectionManager cm = new 
        PoolingHttpClientConnectionManager(socketFactoryRegistry);

        CloseableHttpClient httpClient = HttpClients.custom()
                .setSSLSocketFactory(sslConnectionSocketFactory)
                .setConnectionManager(cm)
                .build();

        HttpPost httpPost = new HttpPost(url);
        httpPost.setEntity(entity);

        int statusCode = 0;
        try (CloseableHttpResponse httpResponse = httpClient.execute(target, httpPost)) {
            statusCode = httpResponse.getStatusLine().getStatusCode();
            //parse response here
        }
}

解决方案非常简单：我的一位朋友告诉我，我应该从 url 中删除“www”。然而，它奏效了！

解决方案非常简单（而且出乎意料）：在我从 URL 中删除“www”部分后，它开始起作用了！！！
