TIMGroupCreate

This API is used to create a group.

Prototype

TIM_DECL int TIMGroupCreate(const char* json_group_create_param, TIMCommCallback cb, const void* user_data);

Parameters

Parameter	Type	Description
json_group_create_param	const char*	JSON string of the API parameter for creating a group.
cb	TIMCommCallback	Callback function for indicating whether a group is created. For more information about the callback function definition and parameter parsing, see TIMCommCallback.
user_data	const void*	User-defined data. The IM SDK only transfers the user data to the callback function cb without processing the data.

Return values

Type	Description
int	If TIM_SUCC is returned, the API was successfully called. (The callback cb is called only when the API returns TIM_SUCC.) If other values are returned, the API failed to be called. For more information about the definition of each return value, see TIMResult.

Note：

• You can specify a group ID when creating a group. If no group ID is specified, the IM server will generate a unique ID to facilitate subsequent operations. The callback set by this API returns the group ID.
• For more information about JSON keys for creating group parameters, see CreateGroupParam.

TIMGroupGetPendencyList

This API is used to obtain the pending request list of a group. Pending requests indicate requests that are not handled, for example, requests for inviting a user to join a group or requesting to join a group.

Prototype

TIM_DECL int TIMGroupGetPendencyList(const char* json_group_getpendence_list_param, TIMCommCallback cb, const void* user_data);

Parameters

Parameter	Type	Description
json_group_getpendence_list_param	const char*	JSON string of the API parameter for obtaining the pending request list of a group.
cb	TIMCommCallback	Callback function for indicating whether the pending request list of a group is obtained. For more information about the callback function definition and parameter parsing, see TIMCommCallback.
user_data	const void*	User-defined data. The IM SDK only transfers the user data to the callback function cb without processing the data.

Return values

Type	Description
int	If TIM_SUCC is returned, the API was successfully called. (The callback cb is called only when the API returns TIM_SUCC.) If other values are returned, the API failed to be called. For more information about the definition of each return value, see TIMResult.

Note：

• Here, group pending requests refer to all group-related operations that need to be approved, for example, a request for joining a group or adding users to a group. You can call this API to obtain a pending request regardless of whether it is approved or rejected, and the returned pending request is marked handled.
• If user A applies to join group A, the group admin can obtain information related to this pending request. As user A does not have the approval permission, user A does not need to obtain this pending request.
• If admin A adds user A to group A, user A can obtain information related to this pending request because user A needs to approve this pending request.
• Permission description:
• Only the approver has the permission to obtain related pending requests.
• kTIMGroupPendencyOptionStartTime specifies the timestamp for obtaining pending requests. It is set to 0 for the first request and later set based on the timestamp specified by kTIMGroupPendencyResultNextStartTime contained in GroupPendencyResult.
• kTIMGroupPendencyOptionMaxLimited specifies the recommended number of pending requests to be obtained. The server can return pending requests as required. However, this key does not indicate whether a pending request is handled.

Example

Json::Value get_pendency_option;
get_pendency_option[kTIMGroupPendencyOptionStartTime] = 0;
get_pendency_option[kTIMGroupPendencyOptionMaxLimited] = 0;
int ret = TIMGroupGetPendencyList(get_pendency_option.toStyledString().c_str(), [](int32_t code, const char* desc, const char* json_param, const void* user_data) {
  if (ERR_SUCC != code) { 
      // Failed to obtain pending requests of a group
      return;
  }
}, nullptr);
// The `json_group_getpendence_list_param` JSON string obtained by `get_pendency_option.toStyledString().c_str()` is as follows:
{
 "group_pendency_option_max_limited" : 0,
 "group_pendency_option_start_time" : 0
}

TIMGroupReportPendencyReaded

This API is used to report that pending requests are read.

Prototype

TIM_DECL int TIMGroupReportPendencyReaded(uint64_t time_stamp, TIMCommCallback cb, const void* user_data);

Parameters

Parameter	Type	Description
time_stamp	uint64_t	Read timestamp (in seconds), which is compared with the time specified by kTIMGroupPendencyAddTime in GroupPendency.
cb	TIMCommCallback	Callback function for indicating whether the read state of pending requests is reported. For more information about the callback function definition, see TIMCommCallback.
user_data	const void*	User-defined data. The IM SDK only transfers the user data to the callback function cb without processing the data.

Return values

Type	Description
int	If TIM_SUCC is returned, the API was successfully called. (The callback cb is called only when the API returns TIM_SUCC.) If other values are returned, the API failed to be called. For more information about the definition of each return value, see TIMResult.

Note：

Group pending requests generated earlier than time_stamp are set to the read state. After the read state is reported, these pending requests can still be obtained. However, you can determine whether these pending requests have been read based on the read timestamp.

TIMGroupHandlePendency

This API is used to handle pending requests of a group.

Prototype

TIM_DECL int TIMGroupHandlePendency(const char* json_group_handle_pendency_param, TIMCommCallback cb, const void* user_data);

Parameters

Parameter	Type	Description
json_group_handle_pendency_param	const char*	JSON string of the API parameter for handling pending requests of a group.
cb	TIMCommCallback	Callback function for indicating whether group pending requests are handled. For more information about the callback function definition, see TIMCommCallback.
user_data	const void*	User-defined data. The IM SDK only transfers the user data to the callback function cb without processing the data.

Return values

Type	Description
int	If TIM_SUCC is returned, the API was successfully called. (The callback cb is called only when the API returns TIM_SUCC.) If other values are returned, the API failed to be called. For more information about the definition of each return value, see TIMResult.

Note：

• The IM SDK provides this API for handling pending requests of a group. An approver can select a single pending request to accept or reject. Pending requests that have been handled cannot be handled again.
• To handle a pending request, GroupPendency must be carried. The pending request can be saved in the pending request list returned by the TIMGroupGetPendencyList API. When a pending request is handled, GroupPendency is passed into the kTIMGroupHandlePendencyParamPendency key.

Example

Json::Value pendency; // Construct GroupPendency
...
Json::Value handle_pendency;
handle_pendency[kTIMGroupHandlePendencyParamIsAccept] = true;
handle_pendency[kTIMGroupHandlePendencyParamHandleMsg] = "I accept this pendency";

int ret = TIMGroupHandlePendency(handle_pendency.toStyledString().c_str(), [](int32_t code, const char* desc, const char* json_param, const void* user_data) {
  if (ERR_SUCC != code) {
      // Failed to handle a group pending request
      return;
  }
}, nullptr);
// The `json_group_handle_pendency_param` JSON string obtained by `handle_pendency.toStyledString().c_str()` is as follows:
{
 "group_handle_pendency_param_handle_msg" : "I accept this pendency",

TIMGroupGetOnlineMemberCount

This API is used to obtain the number of online members of a group.

Prototype

TIM_DECL int TIMGroupGetOnlineMemberCount(const char* groupid, TIMCommCallback cb, const void* user_data);

Parameters

Parameter	Type	Description
group_id	const char*	Group ID.
cb	TIMCommCallback	Callback function for obtaining the number of online members of a group. For more information about the callback function definition, see TIMCommCallback.
user_data	const void*	User-defined data. The IM SDK only transfers the user data to the callback function cb without processing the data.

Return values

Type	Description
int	If TIM_SUCC is returned, the API was successfully called. (The callback cb is called only when the API returns TIM_SUCC.) If other values are returned, the API failed to be called. For more information about the definition of each return value, see TIMResult.

Note：

Notes:

• Currently, this API is supported only by audio-video groups (AVChatRoom).
• This API implements frequency limit checks. It can be called by the SDK for up to once per 60 seconds.

Example

TIMGroupGetOnlineMemberCount("lamarzhang_group_public", [](int32_t code, const char* desc, const char* json_param, const void* user_data) {
}, nullptr);
Example of `json_param`. For details on JSON keys, see [GroupGetOnlineMemberCountResult](TIMCloudCallback.h).
