我在下面的答案中提供了一个工作代码，因为这套API相对较新，我在网络上看不到其他端到端示例，因此可能有用任何希望使用新API API的人的参考资料。
我正在尝试使用WSO2 AM 1.10.0的新发布API集。我根据Sanjeewa Malalgoda的一篇文章写了一个样本客户端：http://wso2.com/library/articles/2015/11/article-introducing-wso2-api-manager-new-rest-api-for-store-and-publisher-operations
以下是基于该文章的代码并修复了一些小错误/拼写错误：

// PHASE 1: REGISTER CLIENT

System.out.println(consumerKey);
System.out.println(consumerSecret);

//Now we have access token and refresh token that we can use to invoke API.
JSONObject tokenData = new JSONObject(accessTokenGenerationResponse.getString("data"));
String userAccessToken = tokenData.getString("access_token");
String refreshToken = tokenData.getString("refresh_token");
System.out.println("Access token: " + userAccessToken);
System.out.println("Refresh token: " + refreshToken);
// PHASE 3: CALL THE API
// ---------------------
Map<String, String> requestHeaders = new HashMap<String, String>();
requestHeaders.put("Authorization", "Bearer " + userAccessToken);
System.out.println(requestHeaders);

System.out.println(response.getResponseCode());
System.out.println(response.getResponseMessage());
}

}

}
代码注册客户端并成功返回访问和刷新令牌。
以下是令牌请求的响应：
"data":
{
"access_token": "bb5176def22ffbc4a7b12d2fd1ee9733",
"refresh_token": "357926275971df21f9529ebb30ba36d1",
"scope":"default",
"token_type":"Bearer",
"expires_in":2502
}
但是，当我在API查询的标题中发送此标记时：
{Authorization=Bearer bb5176def22ffbc4a7b12d2fd1ee9733}
我收到错误代码401 /未经授权。
查看服务器日志，我得到以下信息：

一些注释
答案 0 :(得分：1)
请检查/_system/config/apimgt/applicationdata/tenant-conf.json文件中可用的角色和范围。然后请求带有那里提到的范围的令牌。然后，您将获得具有正确范围的访问令牌。请注意，具有默认范围的令牌不能用于REST API功能。
答案 1 :(得分：1)
对于基本身份验证，请将repository \ deployment \ server \ webapps \ api #am＃publisher＃v0.9 \ WEB-INF的beans.xml更改为：
<bean id="AuthenticationInterceptor" class="org.wso2.carbon.apimgt.rest.api.util.interceptors.auth.BasicAuthenticationInterceptor" />
然后代码大大简化了：
public class test {
public static void main(String[] args) throws
UnsupportedEncodingException,
AutomationFrameworkException,
InterruptedException,
MalformedURLException,
IOException
{
String dcrEndpointURL = getKeyManagerURLHttp()+"client-registration/v0.9/register";
String basicAuthAdmin = "admin" + ":" + "admin";
byte [] encodedBytesAdmin = Base64.getEncoder().encode(basicAuthAdmin.getBytes("UTF-8"));
Map<String, String> requestHeaders = new HashMap<String, String>();
requestHeaders.put("Authorization", "Basic " + new String(encodedBytesAdmin, "UTF-8"));
System.out.println(requestHeaders);
HttpResponse response = HttpRequestUtil.doGet(getKeyManagerURLHttp()+"api/am/publisher/v0.9/apis",requestHeaders);
System.out.println(response.getResponseCode());
System.out.println(response.getResponseMessage());
System.out.println(response.getData());
HttpResponse response1 = HttpRequestUtil.doGet(getKeyManagerURLHttp()+"api/am/publisher/v0.9/subscriptions",requestHeaders);
System.out.println(response1.getResponseCode());
System.out.println(response1.getResponseMessage());
System.out.println(response1.getData());
}
static String getKeyManagerURLHttp()
{
return "http://127.0.0.1:9763/";
}
static String getGatewayURLNhttp()
{
return "http://127.0.0.1:8280/";
}
}
