我如何将Mpesa与Ionic 3集成

Question

我需要将mpesa与ionic 3代码进行集成。让我知道该怎么做。下面是我正在尝试的代码行：

Mpesa是我正在与用户的离子代码集成的支付网关。

     headers = new Headers({
        'Host': 'sandbox.safaricom.co.ke',
        'Content-Type': 'application/json',
        "Authorization": "Bearer " + auth
      });
      console.log("access token", headers);

      let options = new RequestOptions({
        headers: headers,
        method: "post"
      });
      let obj ={
        "Initiator": "testapi0347",
        "SecurityCredential": "mngQ/tfO0ocvXC66Ptzpm9E4JYSQUSmpOMpwQlrDGhpPLLuijC9o+2b6spghKKShWtDDZAvpBLXH/nrKBdheNWo0UuhbxSYq+BZr3vIY/Wxj5y68swuSOs/0gQ8gJ3gCYBZI4NcmAXqpgM3wK6ngPFhUxwDu9cBXM2YEYLmfDpuk4IPcZnEi/g8YpqpdvHB7Fgrz3uu7XHy6ldZXGGyay+r9g8L8gtkR2P8KGEw+QIg1uh+5+P1M/YyQkE7ngJK4cf6KOJ9iSKwmu6VWe/8PW1ZFa4JHUj7H/Pegyz8raUFrAjPLJTkW7Ky/yfBzCmm6PGe2REUwkii8WS/4uQmJvQ==",
        "CommandID": "test111",
        "SenderIdentifierType": "A",
        "RecieverIdentifierType": "B",
        "Amount": 1000,
        "PartyA": "A",
        "PartyB": "B",
        "AccountReference": "Mohit",
        "Remarks": "Payment",
        "QueueTimeOutURL": "",
        "ResultURL": ""
      }
      this.http.post(url,obj,{headers : headers}).subscribe(data=>{
      console.log("data ", data);

    });

对此有任何帮助。
