我的CreateTimeLine代码是

public static void createTimeLine(List<sObject> objList,Map<String,String> contentMap){
Map<Id,User> userMap = new Map<Id,User>([Select id,Name From User where Authorize__c = true]);
Map<Id,GlassUserApiSettings__c> userSettingsMap = new Map<Id,GlassUserApiSettings__c>();

for(Id user_id : userMap.keySet()){
GlassUserApiSettings__c userSettings = GlassUserApiSettings__c.getValues(user_id);
if(userSettings == null)
{ User u =userMap.get(user_id);
u.Authorize__c = false;
update u;
}
else userSettingsMap.put(user_id,userSettings);

}

正如您所看到的，在doApiCall函数之后，我没有使用任何DML语句。但是为什么我要面对这个错误呢？？请使用指南解决此问题。

您在进行标注之前进行更新-

更新u

和

更新用户设置。您应该在调出后进行更新。
但实际上，一个有您声誉的人应该先用谷歌搜索这个问题……事实上，我正在测试的testcase没有涵盖这些DML操作，仍然出现错误，这就是为什么我为没有以正确的方式表示歉意。我在得到这个消息后，通过触发器调用batch apex线路误差
