我试图将多部分/混合请求发送到azure直接批量发送(https://msdn.microsoft.com/en-us/library/azure/mt734910.aspx)。我正在使用npm请求模块。在nodejs中发送多部分/混合请求

我想要什么要求,形成: -

POST https://{Namespace}.servicebus.windows.net/{Notification Hub}/messages/$batch?direct&api-version=2015-08 HTTP/1.1 
Content-Type: multipart/mixed; boundary="simple-boundary" 
Authorization: SharedAccessSignature sr=https%3a%2f%2f{Namespace}.servicebus.windows.net%2f{Notification Hub}%2fmessages%2f%24batch%3fdirect%26api-version%3d2015-08&sig={Signature}&skn=DefaultFullSharedAccessSignature 
ServiceBusNotification-Format: gcm 
Host: {Namespace}.servicebus.windows.net 
Content-Length: 431 
Expect: 100-continue 
Connection: Keep-Alive 


--simple-boundary 
Content-Type: application/json 
Content-Disposition: inline; name=notification 

{"data":{"message":"Hello via Direct Batch Send!!!"}} 
--simple-boundary 
Content-Type: application/json 
Content-Disposition: inline; name=devices 

['Device Token1','Device Token2','Device Token3'] 
--simple-boundary-- 

我曾尝试: -

第一种方法: -

Request({ 
      method: 'POST', 
      uri:'https://{namespace}.servicebus.windows.net/{Notification Hub}/messages/$batch?direct&api-version=2015-08', 
      headers: { 
       Authorization, 
     'Content-Type': 'multipart/mixed; ', 
       'ServiceBusNotification-Format': 'gcm', 
       'x-ms-version': '2015-04' 
      }, 
      multipart: [{ 
       'content-type': 'application/json', 
       body: { 
        data:{"message":"Hello via Direct Batch Send!!!"} 
       } 
      }, { 
       'content-type': 'application/json', 
       body : handles // This is array 
      }] 
     }, (err, res, body) => { 
      console.log('res: ', err, res, body) 
     } 

错误: - 第一个参数必须是一个字符串, Buffer,ArrayBuffer,Array或类似阵列的对象

第二种方法: -

 var formData = { 
      data:{"message":"Hello via Direct Batch Send!!!"}, 
      devices: handles // This is array 
     } 
     var options = { 
     uri:'https://{namespace}.servicebus.windows.net/{Notificatin Hub}/messages/$batch?direct&api-version=2015-08', 
     headers: { 
        Authorization, 
      'Content-Type': 'multipart/mixed; ', 
        'ServiceBusNotification-Format': 'gcm', 
        'x-ms-version': '2015-04' 
     } 
     } 
     Request.post({options, formData}, (err, res, body) => { 
      console.log('res: ', err, res, body) 
     }) 

错误:options.uri是必需的参数

请建议我正确和更好的方法来发送多部分/混合请求到Azure直接批量发送服务。 感谢您

在你的第一种方法转换为缓冲区中的句柄。 const buf1 = new Buffer(handles); –

嘿@PankajJatav改变了句柄来缓冲const bufferHandle = new Buffer(句柄),并在主体中传递了bufferHandle,但它返回错误:无法从请求中读取多部分内容 –

在你的第一种方法,因为你在multipart设置content-typeapplication/json,你应该使用JSON.stringify()方法对身体转换成JSON字符串象下面这样:

multipart: [ 
    { 
    'content-type': 'application/json', 
    body: JSON.stringify({data: {"message": "Hello via Direct Batch Send!!!"}}) 
    }, 
    { 
    'content-type': 'application/json', 
    body : JSON.stringify(handles) 
    } 
]
