Insert post Blogger API failed in GAS

Question

hi all iam trying insert post using GAS but failed.. can you tell me what im wrong... thx in advance....

here my code

`function sendHttpPost() {
 var API_KEY = 'my api key';
 var scope = "http://www.blogger.com/feeds/";       
 var oAuthConfig = UrlFetchApp.addOAuthService("blogger");
 oAuthConfig.setRequestTokenUrl("https://www.google.com/accounts/OAuthGetRequestToken?scope="+scope);
 oAuthConfig.setAuthorizationUrl("https://www.google.com/accounts/OAuthAuthorizeToken");
 oAuthConfig.setAccessTokenUrl("https://www.google.com/accounts/OAuthGetAccessToken");
 oAuthConfig.setConsumerKey("anonymous");
 oAuthConfig.setConsumerSecret("anonymous");
  var payload = 
    {
  "kind": "blogger#post",
  "blog": {
    "id": "486683248036684073"
  },
  "title": "A new post",
  "content": "With <b>exciting</b> content..."
}
  var options =
    {
      "contentType":"application/json",
      "oAuthServiceName" : "blogger",
      "oAuthUseToken" : "always",
      "method" : "POST",
      "payload" : payload
    };

  var respon = UrlFetchApp.fetch("https://www.googleapis.com/blogger/v3/blogs/486683248036684073/posts?key="+API_KEY, options);

and here is error message

Request failed for returned code 400. Server response: { "error": { "errors": [ { "domain": "global", "reason": "parseError", "message": "Parse Error" } ], "code": 400, "message": "Parse Error" } }

The error is pretty vague but I'd start with replacing the content with some simple text of say one line. — Srik, Mar 14 '13 at 23:55

I believe you are trying to use oauth1 when oauth2 is required. there already is a unanswered request about that here. Implementing oauth 2 with Google app script is really a pain, so I made an attempt to build a library that could answer the need (dioxygen library) - it work a little bit like the oauth2 playground but it's less pretty. With a little work you should be able to adapt it to your need with blogger.

I tried Harold's library, but after successfully retrieving OAuth token, I ended up with the same error.

But, when I issued the same JSON request as in my script through the API Explorer, it was processed: https://developers.google.com/blogger/docs/3.0/reference/posts/insert

[UPDATE]

I am taking it back. This code works. I just replaced the payload variable and put the JSON request straight into URL fetch options. So there was some problem with passing that payload variable into options variable.

function testBlogger() {

  var payload =
      {
        "kind": "blogger#post",
        "blog": {
          "id": "YOUR_BLOG_ID"
        },
        "title": "New post",
        "content": "With content..."
      };

  var options =
      {
        "method" : "post",
        "headers" : { "Authorization" : "Bearer YOUR_ACTIVE_TOKEN"},
        "contentType" : "application/json",
        "payload" : '{ "kind": "blogger#post", "blog": { "id": "YOUR_BLOG_ID" }, "title": "New post", "content": "With content..." }'
      };

  try {

    var result = UrlFetchApp.fetch(
      "https://www.googleapis.com/blogger/v3/blogs/YOUR_BLOG_ID/posts",
      options);

    Logger.log(result);

  } catch (e) {
    Logger.log(e);
  }
}
