我正在尝试将发布请求从我的Android应用发送到Express服务器。我创建一个JSON,然后将其转换为字符串,当我记录它时,它看起来像:
{"customerID":"testID"
"productID":"testID",
"productCategory":"testCategory", "city":"Oslo",
"country":"Norway",
"deviceType":"Android",
"token":"5f883e921523d77504eaea12"}
然后,我尝试通过此函数在请求正文中发送它:
try {
URL url = new URL(urlString);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("POST");
out = new BufferedOutputStream(urlConnection.getOutputStream());
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out));
writer.write(data);
writer.flush();
writer.close();
out.close();
urlConnection.connect();
} catch (Exception e) {
Log.d("err", e.getMessage());
}
当我将参数记录到后端时,它会转换为类似的内容:
{
'{"customerID":"testID""productID":"testID","productCategory":"testCategory","city":"Oslo","country":"Norway","deviceType":"Android","token":"5f883e921523d77504eaea12"}': ''
}
我认为问题出在缓冲写入器中,但我不知道如何解决。
