Question

我正在尝试使用Facebook Marketing API在Node.js中制作新的广告系列。

我已成功从此网址获取访问令牌：

var fbApi = {
'method': 'GET',
'url' : 'https://graph.facebook.com/oauth/access_token?client_id=MYCLIENTID&client_secret=MYSECRET&grant_type=client_credentials'
}

然后我发出此POST请求（使用＆＃39;请求＆＃39;模块）。我发布了＆＃39; name＆＃39;和＆＃39; campaign_group_status＆＃39;我理解的是必需的值。

我发布到端点

https://graph.facebook.com/<API_VERSION>/act_<AD_ACCOUNT_ID>/adcampaign_groups

我正在按照文档中的URL传递访问令牌：

http://graph.facebook.com/endpoint?key=value&access_token=app_id|app_secret

完整代码（由虚拟数据替换的敏感信息）：

var request = require('request');

var fbOptions = {
    'name' : 'test2',
    'campaign_group_status' : 'PAUSED'
}

var fbOptionsString = JSON.stringify(fbOptions);



var fbPost = {
    'uri' : ' https://graph.facebook.com/v2.3/act_5374356645419299/adcampaign_groups?access_token=56345345453773242|iert_arfwYfwfwxD-pLxHcpASFTNm',
    'method': 'POST',
    'headers': {
        'Content-Type' : 'application/json',
    },
    'body' : fbOptionsString
}

request(fbPost, function(error, response, body){
    console.log('request says ----', body);
})

我看到的错误回复：

request2 says ---- {"error":{"message":"Unsupported post request.","type":"GraphMethodException","code":100}}

在我收到关于许可的错误之前，另一个人说“＆＃39; name＆＃39;值是必需的。那些已经解决了。所以我相信我有正确的访问权限，Facebook正在获取请求的正文内容。

非常感谢帮助！

如果查看documentation示例，他们会在curl中使用-F选项。

     -F, --form <name=content>
          (HTTP) This lets curl emulate a filled-in form in which a user has pressed the submit button. This causes curl to POST data using the Content-Type  multipart/form-data  according  to  RFC  2388.  This
          enables  uploading of binary files etc. To force the 'content' part to be a file, prefix the file name with an @ sign. To just get the content part from a file, prefix the file name with the symbol <.
          The difference between @ and < is then that @ makes a file get attached in the post as a file upload, while the < makes a text field and just get the contents for that text field from a file.

因此您必须从多部分后期发送数据。请参阅here以了解如何使用node-request。

var request = require('request');

var fbOptions = {
    'name' : 'test2',
    'campaign_group_status' : 'PAUSED'
}

// var fbOptionsString = JSON.stringify(fbOptions);
var fbPost = {
    'uri' : ' https://graph.facebook.com/v2.3/act_5374356645419299/adcampaign_groups?access_token=56345345453773242|iert_arfwYfwfwxD-pLxHcpASFTNm',
    'method': 'POST',
    'headers': {
        'Content-Type' : 'application/json',
    },
    'formData' : fbOptions
}

request(fbPost, function(error, response, body){
    console.log('request says ----', body);
})
