Facebook 测试用户无法发帖

Question

对于我们的网站，我们做了很多自动化测试。因此，最近我刚刚使用 Facebook Graph API 编写了一个方法，该方法可以在 feed 上创建墙贴。 当我使用真实的 Facebook 帐户进行现场测试时，此方法有效。但是，当我使用 facebook 测试用户 （权限设置为“publish_stream”）时，我得到 403 禁止。

“测试用户”不可以发墙帖吗？或者我有什么做得不对的地方吗？

这是我用 groovy 编写的测试代码

void testPostMessageOnWall() {
    def appAccessToken = facebookService.getAppAccessToken()
    assertNotNull appAccessToken

    def testUser1 = facebookService.createTestAccount("Ryoko UserOne", appAccessToken)
    assertNotNull testUser1
    def testUser2 = facebookService.createTestAccount("Ryoko UserTwo", appAccessToken)
    assertNotNull testUser2

    def response = facebookService.connectTwoTestAccount(testUser1.id, testUser1.access_token, testUser2.id, testUser2.access_token)
    assertTrue response

    println testUser1
    println testUser2

    def postResponse = facebookService.postMessageOnWall([accessToken:testUser1.access_token,
                                                          from:testUser1.id,
                                                          to:testUser2.id,
                                                          message:"Join ryoko.it. It's nice there!",
                                                          link:"http://ryoko.it",
                                                          name:"name of website",
                                                          caption:"ryoko.it",
                                                          description:"description",
                                                          picture:"http://ryoko.it/images/ryoko.png"
                                                          ])

    println postResponse
    assertNotNull postResponse

    facebookService.deleteTestAccount(testUser1.id, testUser1.access_token)
    facebookService.deleteTestAccount(testUser2.id, testUser2.access_token)
}

这个测试创建了两个测试用户/帐户并使他们成为彼此的朋友，然后 testUser1 在 testUser2 的墙上发布了一些内容。它失败了：assertNotNull postResponse。

这是响应的标题：

data:
{
  "error": {
    "type": "OAuthException",
    "message": "(#200) The user hasn't authorized the application to perform this action"
   }
}

用户是这样创建的：

def createTestAccount(fullname, appAccessToken) {
    def accessToken = appAccessToken
    def urlString = "${GRAPH_API_URL}/${APP_ID}/accounts/test-users?installed=true"
    def encodedFullname = URLEncoder.encode(fullname, "UTF-8")
    urlString += "&name=${encodedFullname}"
    urlString += "&permission=create_note,email,offline_access,photo_upload,publish_stream,read_friendlists,share_item,status_update,video_upload"
    urlString += "&method=post"
    urlString += "&access_token=${accessToken}"
    def url = new URL(urlString)
    def connection = url.openConnection()
    def userDetails

    if (connection.responseCode == 200) {
        userDetails = JSON.parse(connection.content.text)
    }
    else {
        println "[FACEBOOK]\tResponse code ${connection.responseCode}: ${connection.responseMessage} [${urlString}]"
    }

    userDetails
}

发布消息是这样的：

def postMessageOnWall(params) {
    assert params.accessToken
    assert params.from
    assert params.to

    def content = "access_token=${postEncode(params.accessToken)}"
    if (params.message)     content += "&message=${postEncode(params.message)}"
    if (params.link)        content += "&link=${postEncode(params.link)}"
    if (params.name)        content += "&name=${postEncode(params.name)}"
    if (params.caption)     content += "&caption=${postEncode(params.caption)}"
    if (params.description) content += "&description=${postEncode(params.description)}"
    if (params.picture)     content += "&picture=${postEncode(params.picture)}"
    if (params.from)        content += "&from=${postEncode(params.from)}"
    if (params.to)          content += "&to=${postEncode(params.to)}"

    def urlString = "${GRAPH_API_URL}/${params.to}/feed"
    def url = new URL(urlString)
    def connection = url.openConnection()
    connection.doOutput = true
    connection.setRequestMethod("POST")
    connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded")
    connection.setRequestProperty("Content-Length", "${content.size()}")

    println content

    def writer = new OutputStreamWriter(connection.outputStream)
    writer.write(content)
    writer.flush()
    writer.close()
    connection.connect()

    def response

    if (connection.responseCode == 200) {
        response = JSON.parse(connection.content.text)
    }
    else {
        println "[FACEBOOK]\tResponse code ${connection.responseCode}: ${connection.responseMessage} [${urlString}]"
    }

    println "response: ${response}"

    response
}

尽管它可以使用真实的 Facebook 帐户（通过手动填写 id 和访问令牌），但这仍然困扰着我。我真的很好奇你认为问题可能是什么。

在 createTestAccount() 中，查询参数“permission”应为“permissions”（复数形式）。
