问题描述
我正在尝试编写一个程序,该程序将使用E * Trade API在沙盒环境中交易股票.我正在使用他们的示例代码作为准则,目前.getAuthorizeURL()方法遇到问题.它说它对于String类型是未定义的,但是,在反编译OAuth jar之后,我陷入了如何解决此问题的麻烦之中.
I'm trying to code a program that will trade stocks in a sandbox environment with the E*Trade API. I am using their sample code as a guideline and currently am getting an issue with the .getAuthorizeURL() method. It says that it is undefined for type String however, after decompiling the OAuth jar I am stuck in a rut about how to solve this issue.

request.setEnv(Environment.SANDBOX); // Use sandbox environment
request.setConsumerKey(oauth_consumer_key); //Set consumer key
request.setConsumerSecret(oauth_consumer_secret);
token = client.getRequestToken(request); // Get request-token object
oauth_request_token = token.getToken(); // Get token string
oauth_request_token_secret = token.getSecret(); // Get token secret

String authorizeURL = null;
authorizeURL = client.getAuthorizeUrl(request); // E*TRADE authorization URL
URI uri = new java.net.URI(authorizeURL);

desktop.browse(uri);
return authorizeURL;

推荐答案
您需要配置构建路径,以将Apache log4j记录器(org/apache/log4j/Logger)包含在外部JAR中.它的用途被隐藏在ETRADE代码中.
You need to configure your build path to include the Apache log4j logger (org/apache/log4j/Logger) in your external JARs. It's use is buried down in the ETRADE code.
您要在其中编辑代码?查找针对您的开发环境的说明应该很容易. APACHE是免费的,您可以在此处下载JAR: http://logging.apache.org/log4j/2.x/
What are you editing your code in? It should be easy to find instructions for your development environment. APACHE is free and you can download the JAR here: http://logging.apache.org/log4j/2.x/
请注意ETRADE( https://us.etrade.com/ctnt/dev-portal/getContent?contentUri=V0_Code-Tutorialhttps://us.etrade.com/ctnt/dev-portal/getContent?contentUri = V0_Code-Tutorial ):Java SDK要继续本教程,您必须首先完成E * TRADE Java SDK的安装,其中包括:
