Salesforce 如何下载renderas='；pdf'；来自java的visualforce页面？,salesforce,Salesforce,阅读此页时，我尝试了此代码，但它似乎对我不起作用 ConnectorConfig config = new ConnectorConfig(); config.setUsername(USERNAME); config.setPassword(PASSWORD); connection = Connector.newConnection(config); URL url = new URL("https://c.na14.visual.force.com/apex/ReportPrintOut

阅读此页时，我尝试了此代码，但它似乎对我不起作用

ConnectorConfig config = new ConnectorConfig();
config.setUsername(USERNAME);
config.setPassword(PASSWORD);
connection = Connector.newConnection(config);

URL url = new URL("https://c.na14.visual.force.com/apex/ReportPrintOut?id=");
url.openConnection().addRequestProperty("Authorization", "Bearer " + config.getSessionId());
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.connect();

我可以验证salesforce连接器对象是否成功，因为我没有引发无效的登录异常，并且我可以成功地查询数据。从url调用获得的url数据如下所示，表明会话id存在问题。但是我无法找出问题所在

我通过替换

url.openConnection().addRequestProperty("Authorization", "Bearer " + config.getSessionId());

借

url.openConnection().setRequestProperty("Authorization", "Bearer " + config.getSessionId());
