Salesforce平台可以将contact或者lead导入到Campaign中
即给该Campaign 添加Campaign Members，如下图所示：
使用REST API 可以将联系人导入的同时，将其加入指定的Campaign，好不容易调研出来，一定要记录下来，啊哈哈哈~~~~
step1
用户输入要将该联系人加入的Campaign Name
step2
根据Campaign Name查询该Campaign是否存在
- 若存在，则根据Name获取CampaignId
返回：
{
"attributes": {
"type": "Campaign",
"url": "/services/data/v29.0/sobjects/Campaign/7010O00JulqAC"
},
"Id": "7010O00JulAC",
"Name": "test campaign"
}
- 若不存在，则创建一个相应Name的Campaign，并获取CampaignId
- 请求：POST
https://yourinstance.salesforce.com/services/data/v29.0/sobjects/Campaign {"Name":"yonghu create"} - 返回：
{"id":"7010O00JumPQAS","success":true,"errors":[]}}
step3
导入过程中要先创建accountId（公司唯一标识），然后将该accountId作为参数去上传contact
POST https://yourinstance.salesforce.com/services/data/v29.0/sobjects/Account
POST https://yourinstance.salesforce.com/services/data/v29.0/sobjects/Contact
用户导入Cantact或者Leads完成后，获取其ContactId或LeadId
并通过CampaignId与用户指定的Campaign Name建立联系,成为其Campaign Member
请求：POST
https://yourinstance.salesforce.com/services/data/v29.0/sobjects/CampaignMember {"CampaignId":"701200004nAAQ","LeadId":"00Q0O007IyBUAK","ContactId":"0030O002UMQA3"}返回 Campaign Member ID：
{"id":"00v0O000QAN","success":true,"errors":[]}}
至此，就将cantact/lead导入Campaign啦！
