Esp8266 HttpClient 帖子

Question

我正在尝试使用 HttpPost 在网络上创建对服务器的调用，但我一直收到 -1 的响应（错误：连接被拒绝）

我能够发出 HTTPGet 请求，但我的 httpPost 失败。如果我将尝试发布的相同数据放入 Fiddler 并从那里发布，我会得到 200 OK。

下面是我要执行的代码：

void PostData() {
  String data = "mailSend=1&new=1&rec=Gupta+Classic&topic=ddd&reply=ddd&fbSig=bE9";
  String url = "https://www.shippingmanager.dk/sh/mailbox.php";
  HTTPClient http;
  http.setReuse(true);
  http.begin(url);
  http.addHeader("Host", "www.shippingmanager.dk");
  http.addHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:53.0) Gecko/20100101 Firefox/53.0");
  http.addHeader("Accept-Language", " en-US,en;q=0.5");
  http.addHeader("Accept-Encoding", " gzip, deflate, br");
  http.addHeader("Content-Type", " application/x-www-form-urlencoded; charset=UTF-8");
  http.addHeader("X-Requested-With", " XMLHttpRequest");
  http.addHeader("Referer", " https://www.shippingmanager.dk/sh/?fb_source=shippingmanager.dk");
  http.addHeader("Connection", "keep-alive");
  http.addHeader("Pragma", " no-cache");
  http.addHeader("Cache-Control", " no-cache");

  int result = http.POST(data);
  http.writeToStream(&Serial);
  http.end();

}

这是我在 Fiddler 中发布的原始文本：

POST https://www.shippingmanager.dk/sh/mailbox.php HTTP/1.1
Host: www.shippingmanager.dk
User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:53.0) Gecko/20100101 Firefox/53.0

mailSend=1&new=1&rec=Gupta+Classic&topic=ddd&reply=ddd&fbSig=J9

请有人指出我的问题。

我也尝试了此链接中的代码，但我也失败了:-(

也许问题出在您使用的“https”协议上。我猜“https”有不同的代码，所以再次尝试将 url 中的“https”替换为“http”。
