Question

我想通过Google Apps脚本以G Suite管理员身份更新域用户的签名。

我使用了对Gmail API的HTTP请求，跟随迈克的示例here，并且能够使用它。

以下是我所做的总结：

在Google服务和Google API控制台中启用了Gmail API
在我的项目中添加了OAuth2 for Apps Script库（因为Apps脚本没有为OAuth2协议提供内置支持）
为我的项目创建了一个服务帐户
授予服务帐户的域范围权限
添加＆＃34; https://www.googleapis.com/auth/gmail.settings.sharing＆＃34;范围

以下代码适用于GREAT（请参阅原始版本here）

＆＃13;

function setSignatureWithHTTPRequest(email, signature) {
  var signatureSetSuccessfully = false;
  var authorizationScope = ['https://www.googleapis.com/auth/gmail.settings.sharing'];
  
  var service = getDomainWideDelegationService("Gmail: ", authorizationScope, email);

  if (!service.hasAccess()) {
    Logger.log("failed to authenticate as user " + email);
    Logger.log(service.getLastError());

    signatureSetSuccessfully = service.getLastError();

    return signatureSetSuccessfully;
  } else {
    Logger.log("successfully authenticated as user " + email);
  }
  
  var username = email.split("@")[0];
  var resource = { signature: signature };
  
  var requestBody                = {};
  requestBody.headers            = {"Authorization": "Bearer " + service.getAccessToken()};
  requestBody.contentType        = "application/json";
  requestBody.method             = "PUT";
  requestBody.payload            = JSON.stringify(resource);
  requestBody.muteHttpExceptions = false;

  var emailForUrl = encodeURIComponent(email);

  var url = "https://www.googleapis.com/gmail/v1/users/me/settings/sendAs/" + emailForUrl;

  try {
    var setSignatureResponse = UrlFetchApp.fetch(url, requestBody);
    signatureSetSuccessfully = true;
    Logger.log("setSignatureResponse on successful attempt:" + setSignatureResponse);
  } catch (e) {
    Logger.log("Set signature with HTTP request failed: " + e);
  }
  
  return signatureSetSuccessfully;
}

＆＃13;

但是，当我修改代码以使用Gmail API中的patch方法而不是UrlFetchApp的HTTP请求时，我收到GoogleJsonResponseException: Not Found错误。

＆＃13;

function setSignatureWithMethod(email, signature) {
  var signatureSetSuccessfully = false;
  var authorizationScope = ['https://www.googleapis.com/auth/gmail.settings.sharing'];
  
  var service = getDomainWideDelegationService("Gmail: ", authorizationScope, email);

  if (!service.hasAccess()) {
    Logger.log("failed to authenticate as user " + email);
    Logger.log(service.getLastError());

    signatureSetSuccessfully = service.getLastError();

    return signatureSetSuccessfully;
  } else {
    Logger.log("successfully authenticated as user " + email);
  }
  
  var resource = { signature: signature };
  
  try {
    var setSignatureResponse = Gmail.Users.Settings.SendAs.patch(resource, "me", email);
    Logger.log("setSignatureResponse on successful attempt:" + setSignatureResponse);
    signatureSetSuccessfully = true;
  } catch (e) {
    Logger.log("Set signature with method failed: " + e);
  }

  return signatureSetSuccessfully;
}

＆＃13;

我的问题是双重的。

为什么function setSignatureWithMethod()会产生错误？
另一张提到here的海报＆＃34; ...您需要使用Gmail REST界面使用UrlFetchApp服务来拨打电话而不是Gmail服务...因为脚本不能作为服务帐户运行，仅作为用户帐户运行。＆＃34;这准确吗？ Gmail API提供的方法（列表，修补程序，更新等）是仅用于设置您自己的电子邮件签名（或自己的Gmail设置），而不是用于域中的其他用户吗？

好的，有两件事。

1 - Gmail.Users.Settings.SendAs.patch()无法工作。我认为这是Gmail API如何以任何语言实施的示例，或者是Google提供的here的一部分，无法在Apps脚本中使用

尝试更改此行：

var setSignatureResponse = Gmail.Users.Settings.SendAs.patch(resource, "me", email);

到这个区块：

var requestBody                = {};
requestBody.headers            = {"Authorization": "Bearer " + service.getAccessToken()};
requestBody.contentType        = "application/json";
requestBody.method             = "PATCH";
requestBody.payload            = JSON.stringify(resource);
requestBody.muteHttpExceptions = false;

var emailForUrl = encodeURIComponent(email);

var url = "https://www.googleapis.com/gmail/v1/users/me/settings/sendAs/" + emailForUrl;

try {

  var setSignatureResponse = UrlFetchApp.fetch(url, requestBody);

  signatureSetSuccessfully = true;

  Logger.log("setSignatureResponse on successful attempt:" + setSignatureResponse);

} catch (e) {

  Logger.log("Set signature with HTTP request failed: " + e.message);

}

2 - 不确定这是否重要但您发送数组作为授权范围，但我的原始示例和所有工作代码都使用字符串。

尝试更改此内容：

var authorizationScope = ['https://www.googleapis.com/auth/gmail.settings.sharing'];

到此......

var authorizationScope = 'https://www.googleapis.com/auth/gmail.settings.sharing';

使用Gmail API sendAs.patch方法更改域上用户的签名时出现GoogleJsonResponseException：Not Found错误
