Question

这是我第一次发布到stackOverflow，我想通过oauth2（仅应用程序身份验证）从twitter获取持有者令牌并遵循here的指示，但我的代码返回错误401未经授权

这是我的代码：

package com.example.twitterapp;

import java.net.URLEncoder;

import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.ResponseEntity;

import android.util.Base64;
import android.util.Log;

import com.octo.android.robospice.request.springandroid.SpringAndroidSpiceRequest;

public class BearerTokenJsonRequest extends
        SpringAndroidSpiceRequest<BearerToken> {


    String API_STRING;



    @Override
    public BearerToken loadDataFromNetwork() throws Exception {
        try{
            API_STRING = URLEncoder.encode("xvz1evFS4wEEPTGEFPHBog","UTF-8")+  
                ":"+URLEncoder.encode("L8qq9PZyRg6ieKGEKhZolGC0vJWLw8iEJ88DRdyOg","UTF-8");
            Log.d("JSON" , "apistring: "+ API_STRING);
            }catch(Exception e){
                e.printStackTrace();
            }

        String encodedString = Base64.encodeToString(API_STRING.getBytes("UTF-8"), Base64.DEFAULT);
                Log.d("ENCODED" , "Base64: "+ encodedString);       




        HttpHeaders headers = new HttpHeaders();
        headers.add("Authorization", "Basic " + encodedString); 
        headers.add("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8"); 



        ResponseEntity<BearerToken> entity= getRestTemplate().exchange(
                "https://api.twitter.com/oauth2/token?grant_type=client_credentials", 
                HttpMethod.POST, new HttpEntity<Object>(headers), BearerToken.class);

        return entity.getBody();


    }

}

此代码返回错误401未经授权。我确保消费者密钥和密钥是正确的，尝试url编码Base64编码的字符串

这是我的logcat错误：

Answer 1

您可以使用examples provided by tweeter替换MyClientKey和MyClientSecret，并确保您通过邮寄发送的基本身份验证是正确的吗？

请更换它们并显示日志，以明确表示您已获得Tweeter所需的确切表格。

请注意：之后，您应该隔离代码以生成您发送的令牌，并使用tweeter的示例在单元测试中测试此代码。

使用RoboSpice从Twitter api获取Bearer令牌（仅应用程序身份验证）1.1返回未授权
