我需要向Web服務器發送POST請求並能夠讀取由所述服務器發送的響應。 我嘗試使用HTTPBuilder LIB與此代碼：Groovy HTTPBuilder：從GZIPed分塊響應獲取實體內容
def http = new HTTPBuilder('http://myServer/')
http.setProxy("Proxy_IP", 8080, "http")
postBody = [cmd:'e',format:'sep',c:'a',b:'b',t:'u',r:'r',kl:'lop']
http.post(body: postBody,
requestContentType: URLENC){ resp ->
HttpEntity he = resp.getEntity()
println "${resp.getAllHeaders()}"
println he.getContentType()
println "${resp.getEntity().getContent()}"
}
我得到當這個代碼被執行的例外：
ERROR errors.GrailsExceptionResolver - EOFException occurred when processing request: [GET] /PROJECT/home/index
Unexpected end of ZLIB input stream. Stacktrace follows:

我開啓電線頭調試，這是我所得到的：

所以我想這個問題來自於一個事實，即響應與發送：
Transfer-Encoding: chunked
Content-Encoding: gzip
是否有另一種方法可以做到這一點？ 我做錯了嗎？ 我嘗試了谷歌搜索一段時間，並沒有找到一個好的主角。 在我看來，HTTPBuilder lib在關閉結束後正在獲取實體內容，但是一旦我不在關閉狀態，我就無法訪問實體內容（例外是：無法訪問關閉流）
我真的將欣賞這一個幫助;）
