首先在Marketing Cloud的UI上创建一个contact：
观察Chrome开发者工具network标签页里的HTTP请求：
https://jerry.gcdemo.hybris.com/sap/opu/odata/sap/CUAN_COMMON_SRV/?sap-client=100
这个请求用于读取CSRF token：
点击保存，会发送一个新的HTTP post请求：
请求url：
https://jerry.hybris.com/sap/opu/odata/sap/CUAN_COMMON_SRV/ContactPersons?sap-client=100
再看下重要的请求头部字段：
把第一步获得的CSRF token填到Postman里的header字段里，如图：
body：
{"CountryCode":"CN","City":"Chengdu","FirstName":"Jerry1","LastName":"Wang1","PostalCode":"610093","RegionCode":"","Street":"天府软件园","HouseNumber":"天府软件园","DateofBirth":null,"ContactPersonFacets":[{"Id":"[email protected]","IdOrigin":"EMAIL","Obsolete":false,"Invalid":false},{"Id":"","IdOrigin":"PHONE","Obsolete":false,"Invalid":false},{"Id":"","IdOrigin":"MOBILE","Obsolete":false,"Invalid":false},{"Id":"","IdOrigin":"FAX","Obsolete":false,"Invalid":false}],"IsConsumer":true,"Filter":{"MarketingAreaId":"CXXGLOBAL"}}
状态码201，证明创建成功了：
