Apache HTTPClient 未经授权

Question

我必须在 java 中编写这个 curl 命令的等效项（有效）：

curl https://api.linkedin.com/v2/me -H "Authorization: Bearer xxx"

我正在使用此代码：

import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;

public class testiamo {

    public static void main(String[] args) throws MalformedURLException, IOException{
        CloseableHttpClient client = HttpClientBuilder.create().build();

        HttpPost postRequest = new HttpPost("https://api.linkedin.com/v2/me");
        postRequest.addHeader("Authorization", "Bearer xxx");

        // Getting the response
        HttpResponse rawResponse = client.execute(postRequest);
        final int status = rawResponse.getStatusLine().getStatusCode();
        final StringBuilder response = new StringBuilder();

        // If status == 200 then we get the response (which could be JSON, XML and so on) and save it as a string.
        if(status == HttpStatus.SC_OK)
        {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    rawResponse.getEntity().getContent()));

            String inputLine;

            while ((inputLine = reader.readLine()) != null)
            {
                response.append(inputLine);
            }

            reader.close();
            client.close();
        }
        else
        {
            client.close();
            throw new RuntimeException("Error while doing call!\nStatus: "+ status);
        }


    }
}

但我收到此错误：

ago 04, 2021 10:30:17 AM org.apache.http.client.protocol.ResponseProcessCookies processCookies
WARNING: Invalid cookie header: "Set-Cookie: li_gc=MTswOzE2MjgwNjU4MTc7MjswMjFHaojFfu7ZrccbD2V9NU7pLUJlhg+my7cV7lmf3L/aRg==; Domain=.linkedin.com; Expires=Fri, 21 Jul 2023 00:02:44 GMT; Path=/; Secure; SameSite=None". Invalid 'expires' attribute: Fri, 21 Jul 2023 00:02:44 GMT

Answer 1

试试这个：

HttpPost postRequest = new HttpPost("https://api.linkedin.com/v2/me");

postRequest.setHeader(HttpHeaders.CONTENT_TYPE,"application/json");
postRequest.setHeader(HttpHeaders.AUTHORIZATION, "Bearer " + YOUR_TOKEN);

然后尝试执行请求。

我假设请求是 POST 请求。但如果不是这种情况，则使用相同的方式执行 GET 请求：

CloseableHttpClient client= HttpClients.custom()
        .setDefaultRequestConfig(RequestConfig.custom()
                .setCookieSpec(CookieSpecs.STANDARD).build())
        .build();
HttpGet getRequest = new HttpGet(url);
getRequest.setHeader(HttpHeaders.AUTHORIZATION, "Bearer " + YOUR_TOKEN);

那么获取响应的步骤是一样的。

更新

检查API docs后，请求应该是GET请求。所以使用上面代码的第二个sn-p。

祝你好运！

Java 的 HTTP 客户端不能很好地处理 RFC 规范的 cookie。您可以像这样切换到标准规范：

HttpClient client = HttpClientBuilder
   .create()
   .setDefaultRequestConfig(
      RequestConfig.custom().setCookieSpec(CookieSpecs.STANDARD).build()
   )
   .build();
