swift - 向谷歌表单发出 POST 请求

Question

我想向 Google Form 发出 POST 请求，但遇到找不到页面的情况。我正在关注 this关于使用如何设置 POST 请求的指南。

我正在使用这个 Google 表单:https://docs.google.com/forms/d/1knZJE-3afDGgW9Sqg6Cf6WiMdCSDAkgvi-wc6aRXV3k/viewform

该表单有 3 个字段和一些隐藏的输入字段，例如本教程未提及的 draftResponse 和 pagehistory。

let url = NSURL(string: "https://docs.google.com/spreadsheets/d/1YrQ71fhsX4XQtwV8qHpoHreBeyl1EnNo2pvafsoygtk/edit#gid=990368688")

var request = NSMutableURLRequest(URL: url!)
let session = NSURLSession.sharedSession()

request.HTTPMethod = "POST"

var fieldsToPost = "entry.1959479545=test1&entry.354177126=test2&entry.1807599304=test@gmail.com" as NSString

request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")

request.HTTPBody = fieldsToPost.dataUsingEncoding(NSUTF8StringEncoding)

var task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in

    println("Response \(response)")

    var strData = NSString(data: data, encoding: NSUTF8StringEncoding)

    println(strData)

    if error == nil {
      println("error")
    }

  })


task.resume()

不确定我的 POST 信息或我的实现是否正确。大家怎么看？

下面是我的 Google Form 页面源输入字段:

input type="text" name="entry.1959479545" value="" class="ss-q-short" id="entry_1959479545" dir="auto" aria-label="First Name  " title=""
input type="text" name="entry.354177126" value="" class="ss-q-short" id="entry_354177126" dir="auto" aria-label="Last Name  " title=""
input type="hidden" name="draftResponse" value="[,,"-7091411838997769820"]"
input type="hidden" name="pageHistory" value="0"
input type="hidden" name="fbzx" value="-7091411838997769820"

我在我正在从事的一个实用项目中完成了这个任务，在这个 repo 中查看它:https://github.com/goktugyil/QorumLogs

这里是如何设置它的教程: https://github.com/goktugyil/QorumLogs/blob/master/Log%20To%20GoogleDocs.md

代码如下:

private static func sendError(#text: String) {
    var url = NSURL(string: formURL)
    var postData = formField1 + "=" + text
    postData += "&" + formField2 + "=" + "anothertext"                
    postData += "&" + formField3 + "=" + "anothertext" 
    postData += "&" + formField4 + "=" + "anothertext" 

    var request = NSMutableURLRequest(URL: url!)
    request.HTTPMethod = "POST"
    request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
    request.HTTPBody = postData.dataUsingEncoding(NSUTF8StringEncoding)
    var connection = NSURLConnection(request: request, delegate: nil, startImmediately: true)
}

一个常见的错误是使用输入表单的“名称”字段，但是您应该使用“id”。
