REST请求，通过域验证更新GMAIL签名

Question

我创建了下面的代码，它提供了一些帮助来访问我的域上的任何用户签名，以便在用户之间实现标准化。目前，当我在URLFetch参数中指定方法'PATCH'时，我得到的只是我发送的电子邮件的sendAs资源，包括旧签名。如果我指定了PUT方法，它将删除签名，但不会将我指定的签名设置到该帐户上。有人能帮我看看我做错了什么吗？

function setSignature(user) 
 
{ 
 
    var user = 'me@mydomain.com'; 
 
    var newSig = '<b>This is my new Signature!</b>'; 
 
    var service = getService(user); 
 
    if (service.hasAccess()) { 
 
    var url = 'https://www.googleapis.com/gmail/v1/users/'+user+'/settings/sendAs/'+user; 
 
     
 
     var payload = 
 
     {

     .setSubject(user) 
 

 
     // Set the property store where authorized tokens should be persisted. 
 
     .setPropertyStore(PropertiesService.getScriptProperties()) 
 

 
     // Set the scope. This must match one of the scopes configured during the 
 
     // setup of domain-wide delegation. 
 
     .setScope('https://www.googleapis.com/auth/gmail.settings.basic', 'https://www.googleapis.com/auth/gmail.settings.sharing');

////////////////////////////////////////////////////FUNCTION CLEAR SIGNATURE//////////////////////////////////////////////////////////////////////// 
 
function clearService(){ 
 
    OAuth2.createService('drive') 
 
    .setPropertyStore(PropertiesService.getUserProperties())

}

注：OAuth2用户凭据都存储在一个单独的文件中恒变量，但我已验证凭据返回的有效数据。

谢谢，

我的应用程序的作品，问题是contentType。

尝试：

var formData = {'sendAsEmail':user,'type':'patch','signature': newSig} 
    var options = 
     { 
     'method' : 'put', 
     'muteHttpExceptions': true, 
     'contentType': 'application/json', 
     'headers': {Authorization: 'Bearer ' + service.getAccessToken()}, 
     'payload': JSON.stringify(formData) 
     };
