HTTPGET删除参数 [英] Httpget removes parameters
本文介绍了HTTPGET删除参数的处理方法，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
我想从该网站分析我的序列化的JSON数据：的http：// demos.brianbuikema.com/apps/soa_services/employees?format=JSON
但我的结果是我得到的回复是从该网站的来源$ C $ C：的http：//演示.brianbuikema.com /应用/ soa_services / 的员工？
所以，我某处参数格式= JSON将删除。但我不知道如何连接，其中
这是我的code不介意log.d，它只是对我来说，当我调试的调试。 `
的HttpClient HttpClient的=新DefaultHttpClient（）; // prepare请求对象
HTTPGET HTTPGET =新HTTPGET（http://demos.brianbuikema.com/apps/soa_services/employees?format=JSON）; 字符串结果= NULL;
尝试{
//执行请求
Log.d（BUH，2AA）;
HTT presponse响应= httpclient.execute（HTTPGET）;
Log.d（BUH，2A）;
//获取响应实体持有
HttpEntity实体= response.getEntity（）;
//如果响应未包封的实体，也没有必要
//担心连接释放
Log.d（BUH，2b中）;
如果（实体！= NULL）{
//一个简单的响应读取
Log.d（寮步，2C）;
InputStream的河道= entity.getContent（）;
结果= convertStreamToString（插播广告）;
Log.d（寮步，结果）;
//关闭输入流会触发连接释放
instream.close（）;
}
}赶上（ClientProtocolException E）{
// TODO自动生成catch块
e.printStackTrace（）;
}赶上（IOException异常五）{
// TODO自动生成catch块
e.printStackTrace（）;
} 返回结果;
}私人静态字符串convertStreamToString（InputStream为）{
/ *
*要InputStream中转换为字符串，我们使用
* BufferedReader.readLine（）方法。我们重复，直到的BufferedReader
*返回NULL，这意味着没有更多的数据读取。每一行
*附加到一个StringBuilder并返回为String。
* /
读者的BufferedReader =新的BufferedReader（新的InputStreamReader（是）
8192）;
StringBuilder的SB =新的StringBuilder（）; 串线= NULL;
尝试{
而（（行= reader.readLine（））！= NULL）{
sb.append（行+\\ n）;
}
}赶上（IOException异常五）{
e.printStackTrace（）;
} {最后
尝试{
is.close（）;
}赶上（IOException异常五）{
e.printStackTrace（）;
}
} 返回sb.toString（）;
}`
解决方案
这个错误是从服务器，请求此网址时，它消除了头JSON，
所以你需要添加：
httpget.addHeader（新BasicHeader（接受，应用/ JSON））; 下的HTTPGET
下面是完整的code：
的HttpClient HttpClient的=新DefaultHttpClient（）; // prepare请求对象
HTTPGET HTTPGET =新HTTPGET（URL）;
httpget.addHeader（新BasicHeader（接受，应用/ JSON））;
//httpget.getParams().setParameter(\"format，JSON）; Log.d（Z，httpget.getURI（）的toString（））; //执行请求
HTT presponse响应; 字符串结果= NULL;
尝试{
响应= httpclient.execute（HTTPGET）; //获取响应实体持有
HttpEntity实体= response.getEntity（）;
//如果响应未包封的实体，也没有必要
//担心连接释放 如果（实体！= NULL）{
//一个简单的响应读取
InputStream的河道= entity.getContent（）;
结果= convertStreamToString（插播广告）;
Log.d（Z，结果）;
//关闭输入流会触发连接释放
instream.close（）;
}
}赶上（ClientProtocolException E）{
// TODO自动生成catch块
e.printStackTrace（）;
}赶上（IOException异常五）{
// TODO自动生成catch块
e.printStackTrace（）;
} 返回结果;
}私人静态字符串convertStreamToString（InputStream为）{

i want to parse my serialized JSON data from the website : http://demos.brianbuikema.com/apps/soa_services/employees?format=JSON but my result that i get back is the source code from the site: http://demos.brianbuikema.com/apps/soa_services/employees? So somewhere my parameters format=JSON will delete. but I have no idea how en where
this is my code don't mind the log.d, it's just for me when i'm debugging debugging. `
HttpClient httpclient = new DefaultHttpClient();
// Prepare a request object
HttpGet httpget = new HttpGet("http://demos.brianbuikema.com/apps/soa_services/employees?format=JSON");
String result = null;
try {
// execute the request
Log.d("buh", "2aa");
HttpResponse response = httpclient.execute(httpget);
Log.d("buh", "2a");
// Get hold of the response entity
HttpEntity entity = response.getEntity();
// If the response does not enclose an entity, there is no need
// to worry about connection release
Log.d("buh", "2b");
if (entity != null) {
// A Simple Response Read
Log.d("buh", "2c");
InputStream instream = entity.getContent();
result = convertStreamToString(instream);
Log.d("buh",result);
// Closing the input stream will trigger connection release
instream.close();
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result;
}
private static String convertStreamToString(InputStream is) {
/*
* To convert the InputStream to String we use the
* BufferedReader.readLine() method. We iterate until the BufferedReader
* return null which means there's no more data to read. Each line will
* appended to a StringBuilder and returned as String.
*/
BufferedReader reader = new BufferedReader(new InputStreamReader(is),
8192);
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
} `
解决方案
The mistake was from the server, when requesting this URL, it removes the header JSON,
so you need to add :
httpget.addHeader(new BasicHeader("Accept", "application/json")); under the HttpGet
here is the full code:
HttpClient httpclient = new DefaultHttpClient();
// Prepare a request object
HttpGet httpget = new HttpGet(url);
httpget.addHeader(new BasicHeader("Accept", "application/json"));
//httpget.getParams().setParameter("format", "JSON");
Log.d("z",httpget.getURI().toString());
// Execute the request
HttpResponse response;
String result = null;
try {
response = httpclient.execute(httpget);
// Get hold of the response entity
HttpEntity entity = response.getEntity();
// If the response does not enclose an entity, there is no need
// to worry about connection release
if (entity != null) {
// A Simple Response Read
InputStream instream = entity.getContent();
result = convertStreamToString(instream);
Log.d("z",result);
// Closing the input stream will trigger connection release
instream.close();
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result;
}
private static String convertStreamToString(InputStream is) {
/*
* To convert the InputStream to String we use the BufferedReader.readLine()
* method. We iterate until the BufferedReader return null which means
* there's no more data to read. Each line will appended to a StringBuilder
* and returned as String.
*/
BufferedReader reader = new BufferedReader(new InputStreamReader(is), 8192);
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
