Tôi cần gửi yêu cầu POST tới máy chủ web và có thể đọc phản hồi được gửi bởi máy chủ đã nói. tôi đã cố gắng sử dụng lib HTTPBuilder với mã này:Groovy HTTPBuilder: Lấy nội dung thực thể từ một phản hồi GZIPed Chunked
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()}"
}
tôi nhận được một ngoại lệ khi mã này được thực hiện:
ERROR errors.GrailsExceptionResolver - EOFException occurred when processing request: [GET] /PROJECT/home/index
Unexpected end of ZLIB input stream. Stacktrace follows:

Tôi quay gỡ lỗi trên cho dây và các tiêu đề và đây là những gì tôi nhận được :

Vì vậy, tôi đoán vấn đề xuất phát từ thực tế là câu trả lời được gửi cùng với:
Transfer-Encoding: chunked
Content-Encoding: gzip
Có cách nào khác để thực hiện việc này không? Tôi có làm sai không? Tôi đã cố gắng googling một thời gian và không tìm thấy một dẫn tốt. Dường như với tôi rằng HTTPBuilder lib nhận nội dung thực thể sau khi kết thúc đóng nhưng một khi tôi thoát khỏi sự đóng cửa đó, tôi không thể truy cập nội dung thực thể (ngoại lệ là: Không thể truy cập luồng đã đóng)
Tôi thực sự sẽ đánh giá cao trợ giúp về vấn đề này;)
