本文介绍了与Android HTTP POST问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
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：CLIENtnemo：aa08a1：59Ea7e8cfa7a8582http：//docs.oasis-open.org/wss/2004/01 /绿洲-200401-WSS-wssecuriTY-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 =SIgid0003nemosec：用法=HTTP：//ñemo.intertrust.cOM / 2005/10 / SECUR性/配置文件/>＆LT;/ SOAP-ENV：EnveloPE>
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（）;
}赶上（IOException异常E）{
e.printStackTrace（）;
}
返回responseBuffer;
}

I am using the below code to execute a HTTP POST request. The PostData is in the form of a String
Sample of PostData:
urn:marlin:broadband:1-1:registration-service:linkAcquisitionurn:marlin:organization:testpdc:device-maker-x:clientnemo:aa08a1:59ea7e8cfa7a8582http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" URI="urn:marlin:core:1.0:nemo:protocol:profile:1" wsu:Id="sigid0003" nemosec:Usage="http://nemo.intertrust.com/2005/10/security/profile"/></SOAP-ENV:Envelope>
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;
}
