我正在使用以下代码。(ServiceResponse 是一个仅用于包装响应的对象)
protected ServiceResponse executeHttpPostRequest(URL url,
Map<String, String> parameters) throws IOException {
String charset = "utf-8";
Set<String> keys = parameters.keySet();
StringBuffer query = new StringBuffer();
for (String key : keys) {
query.append(key);
query.append("=");
query.append(URLEncoder.encode(parameters.get(key), charset));
query.append("&");
}
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
if (Build.VERSION.SDK_INT > 13) {
connection.setRequestProperty("Connection", "close");
}
connection.setDoOutput(true);
connection.setChunkedStreamingMode(0);
connection.setRequestMethod("POST");
connection.setRequestProperty("Accept-Charset", charset);
connection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded;charset=" + charset);
connection.setRequestProperty("Content-Length",
Integer.toString(query.length()));
OutputStream output = connection.getOutputStream();
output.write(query.toString().getBytes(charset));
ServiceResponse response = new ServiceResponse();
response.setHttpCode(connection.getResponseCode());
if (connection.getResponseCode() == 200 && connection.getContentLength() > 0) {
response.setInputStream(connection.getInputStream());
}
output.close();
return response;
}
我在调用 HttpURLConnection.getResopnseCode 或 HttpURLConnection.getContentLength 时收到 EOFException,并且服务器仅响应 HTTP 代码 200 但没有内容。我在其他具有正文响应 (JSON) 并且工作正常的服务调用上使用了确切的方法。我在这里看到了类似的帖子,并试图在没有运气的情况下应用修复程序(这就是为什么你可以看到“连接”设置得非常好)。我也在使用System.setProperty("http.keepAlive", "false"); 以防万一。

这是堆栈跟踪
