【问题描述】：

我正在尝试使用 Google Adwords 报告 HTTP POST 请求来检索可能存在于多个广告系列/广告组下的关键字列表的统计信息。这是我提到的 API 文档https://developers.google.com/adwords/api/docs/guides/reporting#prepare-the-http-post-request。

下面是返回 400 错误代码的 scala 代码。我究竟做错了什么？或者是否有其他方法可以从KEYWORDS_PERFORMANCE_REPORT 报告类型中检索数据？

      val httpClient = new DefaultHttpClient()
      val postRequest=new HttpPost("https://adwords.google.com/api/adwords/reportdownload/v201605")
      postRequest.addHeader("Host","adwords.google.com")
      postRequest.addHeader("User-Agent", "curl, gzip")
      postRequest.addHeader("Accept","*/*")
      postRequest.addHeader("Expect","100-continue")
      postRequest.addHeader("Accept-Encoding","gzip")
      postRequest.addHeader("Content-Type","multipart/form-data; boundary=------------------------12d01fae60c7b559; charset=utf-8")
      postRequest.addHeader("Authorization","Bearer 1/*************************************")
      postRequest.addHeader("developerToken","/*************************************")")
      postRequest.addHeader("clientCustomerId","/*************************************")")
      postRequest.addHeader("Parameters","__rdxml: <?xml version=\"1.0\" " +

      val httpResponse=httpClient.execute(postRequest)
      println(httpResponse.getStatusLine.toString)

【解决方案1】：

您的报告定义应进入编码为application/x-www-form-urlencoded 或multipart/form-data 的POST 请求正文——在您的代码中，您将其添加为名为@987654324@ 的标头。
