我使用的是下面的code执行HTTP POST请求。该是的PostData以字符串形式
中的PostData样品：
金塔：枪鱼：广 频段：1-1：registr 通货膨胀业务：丽 nkAcquisitionurn： 马林：organizat 离子：testpdc：德维 CE制造商-X：CLIEN tnemo：aa08a1：59E a7e8cfa7a8582http：//docs.oasi s-open.org/wss/2 004/01 /绿洲-200 401-WSS-wssecuri TY-公用事业1.0.x的 SDURI =金塔：三月 林：核心：1.0：NEM ○：协议：PROFI 乐：1华盛顿州立大学：ID =SI gid0003nemosec ：用法=HTTP：//ñ emo.intertrust.c OM / 2005/10 / SECUR 性/配置文件/>＆LT; / SOAP-ENV：Envelo PE>
我们期待一个XML / SOAP响应，而不是我们得到一个xml文件作为响应。谁能告诉我，如果做一个HTTP POST的程序是正确的（如跌破code）
注：，卷曲用于执行自检工作正常使用时，同样POSTDATA
。 公共字节[] SENDRECV（字符串的PostData，长postDataSize）{
尝试{
如果（！（PostData.equals（空）））{
isPost = TRUE;
// InputStream的postDataInputStream =新ByteArrayInputStream的（POSTDATA）;
// BasicHttpEntity httpPostEntity =新BasicHttpEntity（）;
//httpPostEntity.setContent(postDataInputStream）;
StringEntity httpPostEntity =新StringEntity（的PostData，HTTP.UTF_8）;
//httpPostEntity.setContentLength(postData.length）;
//httpPostEntity.setContentType("application/x-www-form-urlen$c$cd）;
httpPost.setEntity（httpPostEntity）;
httpPost.setHeader（内容长度，新的整数（PostData.length（））的toString（））;
httpPost.setHeader（内容类型，应用程序/ x-WWW的形式urlen codeD）;
httpPost.setHeader（期望，100-继续）;
}
}赶上（例外五）{
e.printStackTrace（）;
}
尝试 {
如果（isPost ==真）{
响应= mAndroidHttpClient.execute（httpPost）;
isPost = FALSE;
}
其他 {
响应= mAndroidHttpClient.execute（HTTPGET）;
}
。状态code = response.getStatusLine（）的getStatus code（）;
如果（状态code！= 200）{
如果（状态code == 404）{
//System.out.println("error在HTTP连接：404）;
//返回ERR_HTTP_NOTFOUND
}否则，如果（状态code == 500）{
//System.out.println("error在HTTP连接：500）;
//返回ERR_HTTP_INTERNALSEVERERROR
} 其他 {
//System.out.println("error在HTTP连接：误差未知）;
//返回ERR_HTTP_FATAL
}
}
HttpEntity实体= response.getEntity（）;
InputStream的是= entity.getContent（）;
ByteArrayOutputStream BOS =新ByteArrayOutputStream（）;
为（中间体下一= is.read（）;！下一= ENDOFSTREAM;接下来= is.read（））{
bos.write（下）;

responseBuffer = bos.toByteArray（）;
bos.flush（）;
bos.close（）;

I am using the below code to execute a HTTP POST request. The PostData is in the form of a String
Sample of PostData:

We are expecting a xml/soap response, instead we are getting an xml file as the response. Can anyone tell me if the procedure to do an HTTP POST is correct (as in the below code)
Note: The same postData when used with cuRL for performing a POST is working fine.
public byte [] sendRecv(String PostData, long postDataSize){
try{
if(!(PostData.equals("empty"))){
isPost = true;
//InputStream postDataInputStream = new ByteArrayInputStream(postData);
//BasicHttpEntity httpPostEntity = new BasicHttpEntity();
//httpPostEntity.setContent(postDataInputStream);
StringEntity httpPostEntity = new StringEntity(PostData, HTTP.UTF_8);
//httpPostEntity.setContentLength(postData.length);
//httpPostEntity.setContentType("application/x-www-form-urlencoded");
httpPost.setEntity(httpPostEntity);
httpPost.setHeader("Content-Length", new Integer(PostData.length()).toString());
httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
httpPost.setHeader("Expect", "100-continue");
}
}catch(Exception e) {
e.printStackTrace();
}
try {
if(isPost == true){
response = mAndroidHttpClient.execute(httpPost);
isPost = false;
}
else {
response = mAndroidHttpClient.execute(httpGet);
}
statusCode = response.getStatusLine().getStatusCode();
if(statusCode != 200 ){
if(statusCode == 404) {
//System.out.println("error in http connection : 404");
//return ERR_HTTP_NOTFOUND
} else if(statusCode == 500){
//System.out.println("error in http connection : 500");
//return ERR_HTTP_INTERNALSEVERERROR
} else {
//System.out.println("error in http connection : error unknown");
//return ERR_HTTP_FATAL
}
}
HttpEntity entity = response.getEntity();
InputStream is = entity.getContent();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
for (int next = is.read(); next != ENDOFSTREAM; next = is.read()) {
bos.write(next);
}
responseBuffer = bos.toByteArray();
bos.flush();
bos.close();
}catch (IOException e) {
e.printStackTrace();
}
return responseBuffer;
}
