下面結合圖式對本發明所述的虛擬資源投遞方法進行詳細的說明。圖1是本發明提供的虛擬資源投遞方法的一種實施例的方法流程示意圖。雖然本發明提供了如下述實施例或圖式所示的方法操作步驟，但基於常規或者無需創造性的勞動在所述方法中可以包括更多或者更少的操作步驟。在邏輯性上不存在必要因果關係的步驟中，這些步驟的執行順序不限於本發明實施例提供的執行順序。所述方法在實際中的虛擬資源投遞過程中或者裝置執行時，可以按照實施例或者圖式所示的方法順序執行或者並行執行（例如平行處理器或者多執行緒處理的環境）。 具體的本發明提供的一種虛擬資源投遞方法的一種實施例如圖1所示，所述方法可以包括： S1：響應於用戶端的資源投遞請求，獲取所述用戶端的資源投遞方向。 在本實施中，可以由伺服器接收用戶端發送的資源投遞請求，並響應於所述資源投遞請求，獲取所述用戶端的資源投遞方向。所述伺服器可以包括具有資料資訊處理功能的硬體設備和驅動該硬體設備工作所需的必要的軟體，所述伺服器可以根據所述用戶端的資源投遞方向確定目標投遞對象。所述伺服器可以提供預定端口，透過所述預定端口可以接收用戶端提供的資源投遞請求。例如，所述伺服器可以基於HTTP、TCP/IP或FTP等網路協議以及網路通訊模組與用戶端進行網路資料互動。 在本實施例中，所述用戶端可以為能夠基於網路協議接入通訊網路並具有虛擬資源投遞功能的終端設備。具體的，例如，所述用戶端可以為行動智慧電話、電腦（包括筆記型電腦，桌上型電腦）、平板電子設備、個人數位助理（PDA）或者智慧可穿戴設備等。此外，所述用戶端還可以為運行於任一上述所列設備上的具有虛擬資源投遞功能的APP，例如支付寶APP、微信APP、釘釘APP等。 在本實施例中，所述虛擬資源可以包括紅包、積分、優惠券、遊戲點卡、比特幣等能夠進行網路支付的資源。在其他實施例中，所述虛擬資源還可以包括任何可以產生使用價值的虛擬資源，本發明在此不做限制。

其中，所述用戶端的空間指向可以包括用戶端設備的空間指向，例如，行動電話的空間指向、智慧手錶的空間指向。在具體的場景中，用戶可以手持用戶端設備，並將所述用戶端設備向任意的方向轉動，用戶端設備最終停留的位置即為所述資源投遞方向。在一個實施例中，用戶端可以透過耦合於設備內部的能夠感應空間方向的感測器獲取所述空間指向，例如，所述感測器可以包括數位電子羅盤、霍爾感測器等。所述用戶端在獲取所述空間指向後，可以將所述空間指向發送至所述伺服器。 在另一個實施例中，所述用戶端的資源投遞方向還可以包括用戶自定義方向。用戶還可以在不需要轉動手機的情況下，確定資源投遞方向。例如，可以在所述用戶端中設置用戶自定義方向選項，用戶可以根據個人的意願、偏好，選取其中任意一個自定義方向。當然，用戶還可以在所述用戶端中輸入自定義方向，用戶確定自定義方向的方式在此不做限制。 在另一個實施例中，所述用戶端的資源投遞方向還可以包括預先設置方向。所述預先設置方向可以是所述用戶端預設設置的空間方向，也可以是隨機產生的空間方向。當然，所述預先設置方向還可以是所述伺服器預設設置的空間方向或者隨機產生的空間方向。 本實施例中，伺服器可以在進行虛擬資源投遞之前，獲取所述用戶端的資源投遞方向，使得虛擬資源投遞行為從現有技術中的無方向性轉變成有方向性，增強用戶在資源投遞過程中的自主選擇權利，提升體驗感。 S2：根據至少一個預設投遞對象的地理位置資訊，從所述至少一個預設投遞對象中確定位於所述資源投遞方向上的目標投遞對象。 本實施例中，所述伺服器在獲取所述用戶端的資源投遞方向之後，可以根據至少一個預設投遞對象的地理位置資訊，從所述至少一個預設投遞對象中確定位於所述資源投遞方向上的目標投遞對象。 所述預設投遞對象可以包括能夠被選取作為目標投遞對象的對象，所述對象可以包括用戶端設備、用戶帳戶等。所述預設投遞對象可以來自於同一設備上的通訊錄、一個或者多個用戶群、同一用戶帳戶的通訊錄，所述預設投遞對象還可以來自於與同一個用戶帳戶相關聯的用戶、用戶群、通訊錄的集合等。例如，所述預設投遞對象為來自同一個微信群、釘釘群、支付寶群等，也可以來自同一部行動電話上的通訊錄，還可以來自與同一個用戶帳戶相關聯的用戶群、用戶、通訊錄等，例如與同一淘寶帳戶相關聯的支付寶、天貓、阿裡媽媽、飛豬等APP帳戶中的用戶群、用戶、通訊錄等。 在本發明的一個實施例中，提出一種根據地理位置資訊確定目標投遞對象的具體實施方式，圖2是本發明提供的確定目標對象的一種實施例的方法流程圖，如圖2所示，所述方法可以包括： S21：獲取至少一個預設投遞對象的地理位置資訊； 為了能夠確定至少一個所述預設投遞對象是否位於所述資源投遞方向上，可以獲取至少一個預設投遞對象的地理位置資訊。 在一個實施例中，所述預設投遞對象的用戶端設備被設置為允許所述伺服器獲取定位資訊，例如GPS定位資訊。此時，所述伺服器可以根據定位資訊獲取所述預設投遞對象的地理位置資訊，例如，所述地理位置資訊可以包括所述預設投遞對象的經度、緯度、海拔高度等。 在另一個實施例中，所述伺服器可以根據所述預設投遞對象的網路標識資訊，獲取所述地預設投遞對象的地理位置資訊。例如，用戶登入帳戶資訊中可以包含所述預設投遞對象的網路標識資訊，如登入IP地址資訊，根據所述登入IP地址資訊可以確定所述預設投遞對象的地理位置資訊。 在其他實施例中，所述伺服器還可以透過任何其他方式獲取所述預設投遞對象的地理位置資訊，本發明在此不做限制。 S22：設置以所述用戶端地理位置為起點的沿著所述資源投遞方向上的目標接收區域； 本實施例中，可以沿著所述資源投遞方向設置能夠接收虛擬資源的目標接收區域。在本發明的一個實施例中，所述目標區域被設置為可以包括下述中的至少一種預設參數：擴張角度區間、投遞距離、投遞路線。 在一個實施例中，所述擴展角度區間可以包括以所述用戶端所在地理位置為起點、以所述資源投遞方向作為軸線的任意偏移角區間。例如，在直線上，所述擴展角度區間為0；在二維空間中，所述擴張角度區間可以包括以所述用戶端所在地理位置為原點、以所述資源投遞方向為座標軸的任意平面上的角度區間。在一個典型的示例中，所述目標區域可以為扇形區域，例如在海拔高度為1米的水平面上，擴張角度的區間可以為[-15°,15°]、[-41°,37°]、[-180°,4°]等等；在三維空間中，所述目標接收區域可以包括以所述用戶端所在地理位置為原點、以所述資源投遞方向為座標軸的規則或者不規則的椎體。三維空間的一個示例中，所述目標接收區域可以為圓錐體，所述擴張角度區間可以為圓錐頂角，如45°、87°、18°等等。在三維空間的另一個示例中，所述目標接收區域可以為規則稜錐體，所述擴張角度區間可以包括椎體頂角、側邊三角形頂角。在三維空間的另一些示例中，所述目標接收區域可以為不規則稜錐體，所述擴張角度區間可以包括椎體頂角區間、側邊三角形頂角區間等。在其他實施例中，所述目標區域還可以包括以所述用戶端所在地理位置為原點、以所述資源投遞方向為座標軸的任意形狀的區域，本發明在此不做限制。 在一個實施例中，所述投遞距離可以包括以所述用戶端所在地理位置為起點的最遠投遞距離。所述距離例如可以設置為3.7米、100米、2000米、無窮大等。 在一個實施例中，所述投遞路線可以包括投遞飛行路線。所述投遞路線可以設置為直線、抛物線、S形曲線、Z形曲線、螺旋曲線等。當然，所述投遞路線可以包括任意形態的曲線，本發明在此不做限制。 在本發明的另一個實施例中，所述目標區域的所述預設參數可以為用戶自定義參數。具體地，用戶可以在用戶端選擇或者輸入預設參數的值。在一個實施例中，用戶可以在用戶端中用文字表示所述預設參數的值。在另一個實施例中，用戶還可以用圖形表示所述預設參數的值，例如，用戶透過觸控螢幕畫出拋物曲線作為所述投遞路線。在其他任意實施例中，用戶還可以透過任意方式自定義所述預設參數的參數值，本發明在此不做限制。 S23：根據所述地理位置資訊，將地理位置位於所述目標接收區域中的至少一個投遞對象作為目標投遞對象。 本實施例中，所述伺服器可以根據所述預設投遞對象的地理位置資訊，將地理位置位於所述目標接收區域中的至少一個投遞對象作為目標投遞對象。例如，在不考慮海拔高度的情況下，設置所述目標接收區域是以所述用戶端所在地理位置為原點、以所述資源投遞方向為座標軸、擴張角度區間為[-15°,15°]的區域，那麼，根據所述預設投遞對象的經度、緯度，可以判斷所述預設投遞對象是否落入所述目標接收區域內，若判斷結果為是，則確定所述預設投遞對象為目標投遞對象。 在本發明的另一個實施例中，進一步地，如圖3所示，所述方法還可以包括： S31：向所述目標投遞對象發送資源投遞通知消息； S32：接收所述目標投遞對象的答覆消息； S33：響應於所述答覆消息，向所述目標投遞對象投遞虛擬資源。 本實施例中，所述伺服器在確定所述目標投遞對象之後，可以進行虛擬資源的投遞。在一個實施例中，可以直接向所述目標投遞對象預設數量的虛擬資源，例如，多個目標投遞對象平均分配或者隨機分配預設金額的紅包。在另一個實施例中，所述虛擬資源的數量為預設數量，可以大於、等於、小於目標投遞對象的數量。在投遞所述虛擬資源的過程中，所述目標投遞對象只是具有領取所述虛擬資源的資格，而最終能不能領取得到取決於虛擬資源的數量與目標投遞對象數量的比例。 在本實施例中，用戶可以選擇領取或者不領取所述虛擬資源，因此，可以在所述伺服器與用戶之間建立反饋機制，所述伺服器可以根據用戶的反饋確定是否發送虛擬資源至所述目標投遞對象。具體地，所述伺服器可以向所述目標投遞對象發送資源投遞通知消息，若所述目標投遞對象的用戶願意接收所述虛擬資源，則可以透過所述目標投遞對象返回答覆消息。所述伺服器可以接收所述目標投遞對象的答覆消息，並響應於所述答覆消息，向所述目標投遞對象投遞虛擬資源。 對應於上述虛擬資源投遞方法，本發明另一方面還提供一種伺服器，如圖4所示，所述伺服器40可以包括： 投遞方向獲取單元41，用於響應於用戶端的資源投遞請求，獲取所述用戶端的資源投遞方向； 目標投遞對象確定單元42，用於根據至少一個預設投遞對象的地理位置資訊，從所述至少一個預設投遞對象中確定位於所述資源投遞方向上的目標投遞對象。 為了能夠清楚地示出本實施例中伺服器與用戶端之間的互動過程，本發明還提供一種虛擬資源的投遞方法，圖5是本發明提供的虛擬資源的投遞方法的另一種實施例的方法流程圖，如圖5所示，所述方法可以包括： S51：用戶端發送資源投遞請求； S52：伺服器接收所述資源投遞請求； S53：所述伺服器響應於所述資源投遞請求，獲取所述用戶端的資源投遞方向； S54：所述伺服器根據至少一個預設投遞對象的地理位置資訊，從所述至少一個預設投遞對象中確定位於所述資源投遞方向上的目標投遞對象。 對應於上述虛擬資源的投遞方法，本發明另一方面還提供一種虛擬資源投遞系統，所述系統包括： 用戶端，用於發送資源投遞請求； 伺服器，用於接收所述資源投遞請求；以及，用於響應於所述資源投遞請求，獲取所述用戶端的資源投遞方向；以及，用於根據至少一個預設投遞對象的地理位置資訊，從所述至少一個預設投遞對象中確定位於所述資源投遞方向上的目標投遞對象。 本發明提供的一種虛擬資源投遞方法及系統、伺服器，可以根據至少一個預設投遞對象的地理位置資訊，從所述至少一個預設投遞對象中確定位於資源投遞方向上的目標投遞對象，實現了向用戶端指定方向進行資源投遞的技術方法。相對於現有技術中資源投遞方法的無方向性、用戶無選擇性，本發明的資源投遞方法可以使得資源投遞具有方向性，給用戶提供更多的資源投遞選擇權，增強用戶的使用體驗感。 本發明另一方面還從用戶端角度提出一種虛擬資源投遞方法，與上述從伺服器角度提出的虛擬資源投遞方法S1-S2不同的地方在於：根據S1-S2，可以發現，確定目標對象的過程均是在伺服器端完成的。而本實施例中，還可以由用戶端自身完成目標對象的確定。具體地，可以參考圖6，所述方法可以包括： S61：獲取至少一個預設投遞對象的地理位置資訊； S62：確定資源投遞方向； S63：根據所述地理位置資訊，從所述至少一個預設投遞對象中確定位於所述資源投遞方向上的目標投遞對象。 本實施例中，所述用戶端可以首先獲取至少一個預設投遞對象的地理位置資訊。如圖7所示，在一個具體的實施例中，所述獲取至少一個預設投遞對象的地理位置資訊可以包括： S71：發送地理位置獲取請求，所述地理位置獲取請求中包括至少一個預設投遞對象的標識資訊； S72：接收所述至少一個預設投遞對象的地理位置資訊。 本實施例中，所述用戶端可以確定至少一個預設投遞對象，所述預設投遞對象可以由用戶自由選擇，也可以是預設用戶群、預設通訊錄中的成員。所述用戶端在確定出所述預設投遞對象之後，可以向所述伺服器發送地理位置獲取請求，所述地理位置獲取請求中包括所述預設投遞對象的標識資訊，所述標識資訊例如所述預設投遞對象的用戶帳號資訊等。 所述伺服器可以響應於所述地理位置獲取請求，根據所述預設投遞對象的標識資訊，獲取並發送所述至少一個預設投遞對象的地理位置資訊。 在本實施例中，步驟S62-S63的實施方式可以參考步驟S2，本發明在此不再贅述。 在一個實施例中，如圖8所示，所述用戶端在確定所述目標投遞對象之後，所述方法還可以包括： S81：發送所述目標投遞對象的標識資訊； S82：接收所述目標投遞對象接收虛擬資源的通知消息。 本實施例中，所述用戶端在確定所述目標投遞對象之後，可以將後續的虛擬資源投遞工作轉移至所述伺服器。具體的，所述用戶端可以將所述目標投遞對象的標識資訊發送至所述伺服器，所述標識資訊例如所述目標投遞對象的用戶帳號資訊。所述伺服器在接收到所述標識資訊後，可以按照步驟S31-S33進行虛擬資源投遞。若虛擬資源投遞成功，所述伺服器可以返回所述目標投遞對象接收虛擬資源的通知消息，所述用戶端在接收到所述通知消息之後，可以確定所述目標投遞對象已成功接收虛擬資源。 對應於上述虛擬資源投遞方法，本發明另一方面還提供一種用戶端，如圖9所示，所述用戶端90可以包括： 地理位置獲取單元91，用於獲取至少一個預設投遞對象的地理位置資訊； 資源投遞方向確定單元92，用於確定資源投遞方向； 目標對象確定單元93，用於根據所述地理位置資訊，從所述至少一個預設投遞對象中確定位於所述資源投遞方向上的目標投遞對象。 為了能夠清楚地示出本實施例中伺服器與用戶端之間的互動過程，本發明還提供一種虛擬資源的投遞方法，圖10是本發明提供的虛擬資源的投遞方法的另一種實施例的方法流程圖，如圖10所示，所述方法可以包括： S101：用戶端發送地理位置獲取請求，所述地理位置獲取請求中包括至少一個預設投遞對象的標識資訊； S102：所述伺服器接收並響應於所述地理位置獲取請求，根據所述標識資訊，發送所述至少一個預設投遞對象的地理位置資訊； S103：所述用戶端接收所述地理位置資訊，並確定資源投遞方向； S104：所述用戶端根據所述地理位置資訊，從所述至少一個預設投遞對象中確定位於所述資源投遞方向上的目標投遞對象。 對應於上述虛擬資源的投遞方法，本發明另一方面還提供一種虛擬資源投遞系統，所述系統包括： 用戶端，用於發送地理位置獲取請求，所述地理位置獲取請求中包括至少一個預設投遞對象的標識資訊；以及，用於接收所述地理位置資訊，並確定資源投遞方向；以及，用於根據所述地理位置資訊，從所述至少一個預設投遞對象中確定位於所述資源投遞方向上的目標投遞對象； 伺服器，用於接收並響應於所述地理位置獲取請求，根據所述標識資訊，發送所述至少一個預設投遞對象的地理位置資訊。 本發明提供的一種虛擬資源投遞方法及系統、用戶端，可以根據至少一個預設投遞對象的地理位置資訊，從所述至少一個預設投遞對象中確定位於資源投遞方向上的目標投遞對象，實現了向用戶端指定方向進行資源投遞的技術方法。相對於現有技術中資源投遞方法的無方向性、用戶無選擇性，本發明的資源投遞方法可以使得資源投遞具有方向性，給用戶提供更多的資源投遞選擇權，增強用戶的使用體驗感。 下面透過具體的應用場景說明本發明的實施例方法。 圖11-13是本發明提供的場景1的示意圖。閒暇時間，用戶小王正在透過用戶端A與大學同學在用戶群B裡玩“紅包接龍”活動。在圖11所示的中國地圖中，用戶端A的地理位置為北緯26.336164°，東經52.030018°。用戶群B中的其他12個成員位於全國各個地方，現在輪到小王發紅包。如圖12所示的“發紅包”使用者介面1，小王設置分發總金額為10元，並將該10元金額分成5個紅包分發。小王點擊使用者介面1中的接收區域設置按鈕，所述使用者介面1跳轉至圖3所示的“接收區域設置”使用者介面2。如圖13所示，所述目標接收區域的三個參數擴張角度區間、投遞距離、投遞路線均可以由用戶自己選擇。假設用戶端A中預設所述目標接收區域只能是扇形或者扇形的組合，海拔高度不限。那麼根據使用者介面2所示的小王的選取，以用戶端A的位置為原點，資源投遞方向為座標軸，擴張角度區間為[-9°,30°]，投遞距離設置為無窮大，投遞路線為直線。當然，在其他的應用場景中，所述投遞路線還可以設置為S型曲線、Z型曲線、抛物線等，所述投遞路線還可以由用戶自己繪製產生。 設置完成目標接收區域的參數之後，小王將用戶端A指向西偏北9°的空間方向，並點擊使用者介面1中的發送紅包按鈕。此時，用戶點擊發送紅包按鈕可以觸發所述用戶端A向伺服器發送資源投遞請求，如圖11所示，所述伺服器根據S1-S2的實施方法，將用戶端A指向的空間方向作為所述資源投遞方向，還可以根據小王設置的目標接收區域的參數值，規劃出如圖11所示的目標接收區域。如圖11所示，伺服器根據群成員1-12的用戶端的地理座標分佈，篩選出群成員1、2、3、6、7、8的用戶端位於所述目標接收區域內，因此，將所述群成員1、2、3、6、7、8的用戶端作為目標投遞對象。 圖14是本發明提供的場景2的示意圖。圖14是某公司的4層寫字樓結構圖，在一個由14個員工組成的用戶群裡，正在進行“紅包接龍”活動。現在輪到14號員工發送紅包，14號員工設置擴張角度區間為[-30°,30°]，投遞距離為10米。設置完成後，14號員工將用戶端B對準上方與水平面成80°角的方向，並發送紅包。伺服器響應於用戶端B的資源投遞請求，規劃出如圖14所示的目標接收區域，根據群成員1-14的用戶端的地理座標分佈，篩選出只有4、8、9、10號員工的用戶端位於所述目標接收區域內，因此，將4、8、9、10號員工的用戶端作為目標投遞對象。 在20世紀90年代，對於一個技術的改進可以很明顯地區分是硬體上的改進（例如，對二極體、電晶體、開關等電路結構的改進）還是軟體上的改進（對於方法流程的改進）。然而，隨著技術的發展，當今的很多方法流程的改進已經可以視為硬體電路結構的直接改進。設計人員幾乎都透過將改進的方法流程編程到硬體電路中來得到相應的硬體電路結構。因此，不能說一個方法流程的改進就不能用硬體實體模組來實現。例如，可程式邏輯裝置（Programmable Logic Device, PLD）（例如現場可程式閘陣列（Field Programmable Gate Array，FPGA））就是這樣一種集成電路，其邏輯功能由用戶對裝置編程來確定。由設計人員自行編程來把一個數位系統“集成”在一片PLD上，而不需要請晶片製造廠商來設計和製作專用的集成電路晶片。而且，如今，取代手工地製作集成電路晶片，這種編程也多半改用“邏輯編譯器（logic compiler）”軟體來實現，它與程式開發撰寫時所用的軟體編譯器相類似，而要編譯之前的原始碼也得用特定的編程語言來撰寫，此稱之為硬體描述語言（Hardware Description Language，HDL），而HDL也並非僅有一種，而是有許多種，如ABEL（Advanced Boolean Expression Language）、AHDL（Altera Hardware Description Language）、Confluence、CUPL（Cornell University Programming Language）、HDCal、JHDL（Java Hardware Description Language）、Lava、Lola、MyHDL、PALASM、RHDL（Ruby Hardware Description Language）等，目前最普遍使用的是VHDL（Very-High-Speed Integrated Circuit Hardware Description Language）與Verilog。本領域技術人員也應該清楚，只需要將方法流程用上述幾種硬體描述語言稍作邏輯編程並編程到集成電路中，就可以很容易得到實現該邏輯方法流程的硬體電路。 控制器可以按任何適當的方式實現，例如，控制器可以採取例如微處理器或處理器以及儲存可由該（微）處理器執行的電腦可讀程式碼（例如軟體或韌體）的電腦可讀媒體、邏輯閘、開關、專用集成電路（Application Specific Integrated Circuit，ASIC）、可程式邏輯控制器和嵌入微控制器的形式，控制器的例子包括但不限於以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20 以及Silicone Labs C8051F320，記憶體控制器還可以被實現為記憶體的控制邏輯的一部分。本領域技術人員也知道，除了以純電腦可讀程式碼方式實現控制器以外，完全可以透過將方法步驟進行邏輯編程來使得控制器以邏輯閘、開關、專用集成電路、可程式邏輯控制器和嵌入微控制器等的形式來實現相同功能。因此這種控制器可以被認為是一種硬體部件，而對其內包括的用於實現各種功能的裝置也可以視為硬體部件內的結構。或者甚至，可以將用於實現各種功能的裝置視為既可以是實現方法的軟體模組又可以是硬體部件內的結構。 上述實施例闡明的系統、單元，具體可以由電腦晶片或實體實現，或者由具有某種功能的產品來實現。一種典型的實現設備為電腦。具體的，電腦例如可以為個人電腦、膝上型電腦、蜂窩電話、相機電話、智慧電話、個人數位助理、媒體播放器、導航設備、電子郵件設備、遊戲控制台、平板電腦、可穿戴設備或者這些設備中的任何設備的組合。 為了描述的方便，描述以上裝置時以功能分為各種單元分別描述。當然，在實施本發明時可以把各單元的功能在同一個或多個軟體和/或硬體中實現。 本領域內的技術人員應明白，本發明的實施例可提供為方法、系統、或電腦程式產品。因此，本發明可採用完全硬體實施例、完全軟體實施例、或結合軟體和硬體方面的實施例的形式。而且，本發明可採用在一個或多個其中包含有電腦可用程式碼的電腦可用儲存媒體（包括但不限於磁碟記憶體、CD-ROM、光學記憶體等）上實施的電腦程式產品的形式。 本發明是參照根據本發明實施例的方法、設備（系統）、和電腦程式產品的流程圖和／或方塊圖來描述的。應理解可由電腦程式指令實現流程圖和／或方塊圖中的每一流程和／或方塊、以及流程圖和／或方塊圖中的流程和／或方塊的結合。可提供這些電腦程式指令到通用電腦、專用電腦、嵌入式處理機或其他可程式資料處理設備的處理器以產生一個機器，使得透過電腦或其他可程式資料處理設備的處理器執行的指令產生用於實現在流程圖一個流程或多個流程和／或方塊圖一個方塊或多個方塊中指定的功能的裝置。 這些電腦程式指令也可儲存在能引導電腦或其他可程式資料處理設備以特定方式工作的電腦可讀記憶體中，使得儲存在該電腦可讀記憶體中的指令產生包括指令裝置的製造品，該指令裝置實現在流程圖一個流程或多個流程和／或方塊圖一個方塊或多個方塊中指定的功能。 這些電腦程式指令也可裝載到電腦或其他可程式資料處理設備上，使得在電腦或其他可程式設備上執行一系列操作步驟以產生電腦實現的處理，從而在電腦或其他可程式設備上執行的指令提供用於實現在流程圖一個流程或多個流程和／或方塊圖一個方塊或多個方塊中指定的功能的步驟。 在一個典型的配置中，計算設備包括一個或多個處理器(CPU)、輸入/輸出介面、網路介面和內存。 內存可能包括電腦可讀媒體中的非永久性記憶體，隨機存取記憶體(RAM)和／或非易失性內存等形式，如唯讀記憶體(ROM)或快閃隨機存取記憶體(flash RAM)。內存是電腦可讀媒體的示例。 電腦可讀媒體包括永久性和非永久性、可移動和非可移動媒體可以由任何方法或技術來實現資訊儲存。資訊可以是電腦可讀指令、資料結構、程式的模組或其他資料。電腦的儲存媒體的例子包括，但不限於相變內存(PRAM)、靜態隨機存取記憶體(SRAM)、動態隨機存取記憶體(DRAM)、其他類型的隨機存取記憶體(RAM)、唯讀記憶體(ROM)、電可擦除可程式唯讀記憶體(EEPROM)、快閃記憶體或其他內存技術、唯讀光碟(CD-ROM)、數位化多功能光碟(DVD)或其他光學儲存、磁盒式磁帶，磁帶磁磁碟儲存或其他磁性儲存設備或任何其他非傳輸媒體，可用於儲存可以被計算設備存取的資訊。按照本文中的界定，電腦可讀媒體不包括暫存電腦可讀媒體(transitory media)，如調變的資料信號和載波。 還需要說明的是，術語“包括”、“包含”或者其任何其他變體意在涵蓋非排他性的包含，從而使得包括一系列要素的過程、方法、商品或者設備不僅包括那些要素，而且還包括沒有明確列出的其他要素，或者是還包括為這種過程、方法、商品或者設備所固有的要素。在沒有更多限制的情況下，由語句“包括一個……”限定的要素，並不排除在包括所述要素的過程、方法、商品或者設備中還存在另外的相同要素。 本領域技術人員應明白，本發明的實施例可提供為方法、系統或電腦程式產品。因此，本發明可採用完全硬體實施例、完全軟體實施例或結合軟體和硬體方面的實施例的形式。而且，本發明可採用在一個或多個其中包含有電腦可用程式碼的電腦可用儲存媒體（包括但不限於磁碟記憶體、CD-ROM、光學記憶體等）上實施的電腦程式產品的形式。

The following describes the method of the embodiments of the present invention through specific application scenarios. Figures 11-13 are schematic diagrams of scene 1 provided by the present invention. In his free time, user Xiao Wang is playing "Red Packet Solitaire" in user group B through user A and university classmates. In the map of China shown in FIG. 11, the geographic location of user terminal A is 26.336164° north latitude and 52.030018° east longitude. The other 12 members of user group B are located in various parts of the country, and now it is Xiao Wang’s turn to send red envelopes. As shown in the user interface 1 of "red envelope" shown in FIG. 12, Xiao Wang sets the total amount of distribution to 10 yuan, and divides the 10 yuan amount into 5 red envelopes for distribution. Xiao Wang clicks the receiving area setting button in the user interface 1, and the user interface 1 jumps to the "receiving area setting" user interface 2 shown in FIG. As shown in FIG. 13, the three parameter expansion angle intervals, delivery distance, and delivery route of the target receiving area can be selected by the user himself. It is assumed that the target receiving area in the user terminal A can only be a fan shape or a combination of fan shapes, and the altitude is not limited. Then according to the selection of Xiao Wang shown in the user interface 2, the position of the user terminal A is the origin, the resource delivery direction is the coordinate axis, the expansion angle interval is [-9°, 30°], the delivery distance is set to infinity, delivery The route is straight. Of course, in other application scenarios, the delivery route can also be set as an S-shaped curve, a Z-shaped curve, a parabola, etc. The delivery route can also be drawn by the user. After setting the parameters of the target receiving area, Xiao Wang points the user terminal A to the spatial direction of 9° northwest, and clicks the send red envelope button in the user interface 1. At this time, the user clicks the send red envelope button to trigger the client A to send a resource delivery request to the server. As shown in FIG. 11, the server uses the spatial direction pointed by the client A as In the resource delivery direction, the target receiving area as shown in FIG. 11 can also be planned according to the parameter value of the target receiving area set by Xiao Wang. As shown in FIG. 11, the server filters out the client terminals of the group members 1, 2, 3, 6, 7, and 8 in the target receiving area according to the geographical coordinates of the client terminals of the group members 1-12. Therefore, The clients of the group members 1, 2, 3, 6, 7, 8 are targeted for delivery. FIG. 14 is a schematic diagram of Scene 2 provided by the present invention. Figure 14 is a structure diagram of a company's 4-storey office building. In a user group composed of 14 employees, the "Red Packet Solitaire" activity is in progress. Now it’s employee No. 14’s turn to send red envelopes. Employee No. 14 sets the expansion angle range to [-30°, 30°] and the delivery distance is 10 meters. After the setting is completed, employee No. 14 points user B at an angle of 80° above the horizontal plane and sends a red envelope. In response to the resource delivery request of client B, the server plans the target receiving area as shown in FIG. 14, and filters out only employees 4, 8, 9, and 10 based on the geographic coordinates of the client of group members 1-14. The user terminal is located in the target receiving area. Therefore, the user terminals of employees No. 4, 8, 9, and 10 are targeted for delivery. In the 1990s, the improvement of a technology can be clearly distinguished from the improvement of hardware (for example, the improvement of the circuit structure of diodes, transistors, switches, etc.) or the improvement of software (for the process flow Improve). However, with the development of technology, the improvement of many methods and processes can be regarded as a direct improvement of the hardware circuit structure. Designers almost get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method and process cannot be achieved with hardware physical modules. For example, a programmable logic device (Programmable Logic Device, PLD) (such as a field programmable gate array (Field Programmable Gate Array, FPGA)) is such an integrated circuit whose logic function is determined by the user programming the device. Designers can program themselves to "integrate" a digital system on a PLD without having to ask the chip manufacturer to design and make a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is also mostly implemented with "logic compiler" software, which is similar to the software compiler used in program development and writing, but before compilation The source code of must also be written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), and HDL is not only one, but there are many, such as ABEL (Advanced Boolean Expression Language ), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog are used. Those skilled in the art should also understand that it is easy to obtain the hardware circuit that implements the logic method flow by only slightly programming the method flow in the above hardware description languages and programming it into the integrated circuit. The controller can be implemented in any suitable way, for example, the controller can take, for example, a microprocessor or processor and a computer-readable program code (such as software or firmware) that can be executed by the (micro)processor Media, logic gates, switches, application specific integrated circuits (ASICs), programmable logic controllers and embedded microcontrollers. Examples of controllers include but are not limited to the following microcontrollers: ARC 625D, Atmel AT91SAM , Microchip PIC18F26K20 and Silicone Labs C8051F320, the memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that, in addition to implementing the controller in a pure computer-readable program code manner, it is entirely possible to make the controller with logic gates, switches, special integrated circuits, programmable logic controllers and embedded The same function is realized in the form of a microcontroller or the like. Therefore, such a controller can be regarded as a hardware component, and the device for implementing various functions included therein can also be regarded as a structure within the hardware component. Or even, the device for realizing various functions can be regarded as both a software module of the implementation method and a structure in the hardware component.
