描述

This function can be used to send a query request. You first define the query using the appropriate steam_ugc_create_query_*() functions which will return a "query Handle". This handle is then used to set filters etc.... before being used in this funtion to send off the query request. The function returns a unique async ID value which can be used to check the details correctly in the Steam Async event. This event will have the async_load DS map which will be populated with the following key/value pairs:

1. "id" - 触发事件的函数返回的异步 ID
2. 
   
3. "result" - 操作的结果（实际值）。这将是 GML 常量 ugc_result_success 或其他一些实数。So you should check for this constant to ensure that the call was successful, and if otherwise somthing has not worked correctly. 返回的其余可能值显示为 Steam “EResult” 值的结果，你应该在 SDK 头文件 steamclientpublic.h 中看到所有 89 个可能值。
4. 
   
5. "event_type" - The string "ugc_query"
6. 
   
7. "num_results" - The number of results returned (max 50 )
8. 
   
9. "total_matching" - The total number of matching results
10. 
    
11. "cached_data" - Indicates whether this data was retrieved from the local on-disk cache or not (will be either true or false)
12. 
    
13. "results_list" - A DS list index index, where each list entry is a DS Map index containing details of the particular item

When you get the async event type "ugc_query", you can then parse the results list and extract the following information from each of the DS maps (one map per item in the list):

1. "published_file_id"" -Holds the unique published file id for the item
2. 
   
3. "file_type" - The type of file used
4. 
   
5. "creator_app_id" - The Steam ID of the item creator
6. 
   
7. "consumer_app_id" - The Steam ID of the item consumer
8. 
   
9. "title" - The title of the item
10. 
    
11. "description" - The description of the item
12. 
    
13. "steam_id_owner" - The Steam ID of the item owner
14. 
    
15. "time_created" - The time the item was first created
16. 
    
17. "time_updated" - The last time the item was updated
18. 
    
19. "time_added_to_user_list" - The time that the item was subscribed to
20. 
    
21. "visibility" - The visibility of the item (see steam_ugc_set_item_visibility() for the returned constants)
22. 
    
23. "banned" - Whether the item has been banned (true) or not (false)
24. 
    
25. "accepted_for_use" - Whether the item has been accepted for use (true) or not (false)
26. 
    
27. "tags_truncated" - Short version of the tags as an array
28. 
    
29. "tags" - A string containing the tags for the item, each one separated by a comma
30. 
    
31. "handle_file" - The unique file handle for the item
32. 
    
33. "handle_preview_file" - The unique handle for the image preview for the item (can be used as an argument with steam_ugc_download() to download a preview image)
34. 
    
35. "filename" - The name of the item file
36. 
    
37. "file_size" - The size of the item file
38. 
    
39. "preview_file_size" - The size of the preview image
40. 
    
41. "url" - The full URL for the item
42. 
    
43. "votes_up" - The number of up-votes received
44. 
    
45. "votes_down" - The number of down-votes received
46. 
    
47. "score" - The overall score of the item
48. 
    
49. "account_id_owner" - The account ID from the Steam ID owner (this can be used in the function steam_ugc_create_query_user_ex())
50. 
    

例如：

var query_handle = steam_ugc_create_query_all(ugc_query_RankedByTrend, ugc_match_Items, 1);
steam_ugc_query_add_required_tag(query_handle, "RPG");
steam_ugc_query_set_return_long_description(query_handle, true);
steam_ugc_query_set_allow_cached_response(query_handle, true);
query_ID = steam_ugc_send_query(query_handle);

The above code creates a query request and stores it's handle in a local variable for future use in the rest of the functions which further define the query request before sending the query.
