我正在尝试保存 parse4cn1 3.0 ParseUser 或 ParseObject。该对象保存在模拟器上，但是在 Java 脚本端口上我收到错误。注意 ParseFile save() 适用于模拟器和 Java 脚本端口。
public void createTask(String userObjectId, String taskName, String taskDescription, String url) {
try {
ParseObject task = ParseObject.create("Task");
task.put("userId", userObjectId);
task.put("taskName", taskName);
task.put("taskDescription", taskDescription);
task.put("url", url);
task.save();
} catch (ParseException e) {
e.printStackTrace();
}
}

Currently 'stopOnErrors' is on. With this enabled, even build warnings will cause the build to fail.
Try adding the 'javascript.stopOnErrors=false' build hint and see if it builds.
WARNING: switching stopOnErrors off may result in runtime errors, if the warnings actually fall in the execution path of the app.
最佳答案
看起来 JavaScript 端口中缺少 getCanonicalName()。我不确定这是我们应该在 JavaScript 端口中修复还是作为拉取请求添加到 parse4cn1。这对于解析 based on this search 似乎不是必需的.
由于该方法一开始就已弃用且不推荐使用，因此我确定可以将其删除。
关于javascript - 使用 parse4cn1 库在 Codenameone 上保存 ParseUser 或 ParseObject 时出错，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41744822/
