我有一个Android应用程序，可以在Web服务中进行咨询和插入。 所有这一切都通过apache HTTPClient和JSON。
所以例如我将一个新用户插入db。
HttpClient httpclient = new DefaultHttpClient();
// 2. make POST request to the given URL
HttpPost httpPost = new HttpPost(url);
String json = "";
// 3. build jsonObject
JSONObject jsonObject2 = new JSONObject();
jsonObject2.put("name", name);
jsonObject2.put("number", num);
// 4. convert JSONObject to JSON to String
json = jsonObject.toString();
// 5. set json to StringEntity
StringEntity se = new StringEntity(json);
// 6. set httpPost Entity
httpPost.setEntity(se);
// 7. Set some headers to inform server about the type of the content
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-type", "application/json");
// 8. Execute POST request to the given URL
HttpResponse httpResponse = httpclient.execute(httpPost);
所有完美创建，现在我想使用我在其余api中创建的方法，方法PUT覆盖例如ID为5的用户的名称如果我想要输入我的URL + / ID并得到一个特定的用户。到＆＃34; PUT＆＃34;我这样做但不起作用。
@Override
protected String doInBackground(String... params) {
InputStream inputStream = null;
String result = "";
try {
// 1. create HttpClient
HttpClient httpclient = new DefaultHttpClient();
// 2. make POST request to the given URL
HttpPut httpPut = new
HttpPut("http://000.000.0.000:0000/xxxxxx/webresources/net.xxxxx.users/5");
String json = "";
// // 3. build jsonObject
// JSONObject jsonObject2 = new JSONObject();
// jsonObject2.put("idGuarderias", idG);
// 3. build jsonObject
JSONObject jsonObject = new JSONObject();
jsonObject.put("name",newName);
// jsonObject.put("guarderiasIdGuarderias",jsonObject2);
json = jsonObject.toString();
StringEntity se = new StringEntity(json);
// 6. set httpPost Entity
httpPut.setEntity(se);
// 7. Set some headers to inform server about the type of the content
httpPut.addHeader("Accept", "application/json");
httpPut.addHeader("Content-type", "application/json");
// 8. Execute POST request to the given URL
HttpResponse httpResponse = httpclient.execute(httpPut);
} catch (Exception e) {
Log.d("InputStream", e.getLocalizedMessage());
}
我应该做出哪些改变？

也许你可以试试这个：
@Override
protected String doInBackground(String... params) {
InputStream inputStream = null;
String result = "";
try {
// 1. create HttpClient
HttpClient httpclient = new DefaultHttpClient();
// 2. make POST request to the given URL
HttpPut httpPut = new
HttpPut("http://000.000.0.000:0000/xxxxxx/webresources/net.xxxxx.users/5");
String json = "";
// // 3. build jsonObject
// JSONObject jsonObject2 = new JSONObject();
// jsonObject2.put("idGuarderias", idG);
// 3. build jsonObject
JSONObject jsonObject = new JSONObject();
jsonObject.put("name",newName);
// jsonObject.put("guarderiasIdGuarderias",jsonObject2);
json = jsonObject.toString();
StringEntity se = new StringEntity(json);
// 6. set httpPost Entity
httpPut.setEntity(se);
// 7. Set some headers to inform server about the type of the content
httpPut.addHeader("Accept", "application/json");
httpPut.addHeader("Content-type", "application/json");
// 8. Execute POST request to the given URL
HttpResponse httpResponse = httpclient.execute(httpPut);
//Try to add this
inputStream = httpResponse.getEntity().getContent();
if(inputStream != null)
result = convertInputStreamToString(inputStream);
else
result = "Did not work!";
} catch (Exception e) {
//Log.d("InputStream", e.getLocalizedMessage());
}
return result;
}

试试这段代码： 您可以在jsonObject对象中添加参数
JSONObject jsonObject = new JSONObject();
jsonObject.put("name",newName);
try {
HttpResponse response;
HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters, TIMEOUT);
HttpConnectionParams.setSoTimeout(httpParameters, TIMEOUT);
HttpClient httpClient = new DefaultHttpClient(httpParameters);
HttpPut putConnection = new HttpPut(url);
putConnection.setHeader("json", jsonObject.toString());
StringEntity se = new StringEntity(jsonObject.toString(), "UTF-8");
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,
"application/json"));
putConnection.setEntity(se);
try {
response = httpClient.execute(putConnection);
String JSONString = EntityUtils.toString(response.getEntity(),
"UTF-8");
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}

我用以下代码解决了我的问题，感谢您的回复。
@Override
protected String doInBackground(String... params) {
InputStream inputStream = null;
String result = "";
try {
// 1. create HttpClient
HttpClient httpclient = new DefaultHttpClient();
// 2. make POST request to the given URL
HttpPut httpPUT = new
HttpPut("http://xxx.xx.x.xxx:xxxx/xxxxxxxy/webresources/net.xxxxxx.users/3");
String json = "";
// 3. build jsonObject
JSONObject jsonObject = new JSONObject();
jsonObject.put("idUser","3");
jsonObject.put("name","Mark");
jsonObject.put("pass","1234");
jsonObject.put("rol","554");
jsonObject.put("usuario","mark");
// 4. convert JSONObject to JSON to String
json = jsonObject.toString();
// 5. set json to StringEntity
StringEntity se = new StringEntity(json);
// 6. set httpPost Entity
httpPUT.setEntity(se);
// 7. Set some headers to inform server about the type of the content
httpPUT.setHeader("Accept", "application/json");
httpPUT.setHeader("Content-type", "application/json");
// 8. Execute POST request to the given URL
HttpResponse httpResponse = httpclient.execute(httpPUT);
// 9. receive response as inputStream
// inputStream = httpResponse.getEntity().getContent();
// // 10. convert inputstream to string
// if(inputStream != null)
// result = convertInputStreamToString(inputStream);
// else
// result = "Did not work!";
} catch (Exception e) {
Log.d("InputStream", e.getLocalizedMessage());
}
return "EXITO!";
}
他们应该将id放在url中，并覆盖所有参数，包括id

希望这对某人有所帮助：
请注意，此处authToken是可选的
public JSONObject makePutRequest(String path, String params, String authToken) {
try {
//instantiates httpclient to make request
@SuppressWarnings("deprecation")
DefaultHttpClient httpclient = new DefaultHttpClient();
//url with the post data
@SuppressWarnings("deprecation")
HttpPut httpost = new HttpPut(path);
if (authToken != null) {
httpost.setHeader("X-Auth-Token", authToken);
}
//passes the results to a string builder/entity
@SuppressWarnings("deprecation")
StringEntity se = new StringEntity(params.toString());
//sets the post request as the resulting string
httpost.setEntity(se);
//sets a request header so the page receving the request
//will know what to do with it
httpost.setHeader("Accept", "application/json");
httpost.setHeader("Content-type", "application/json");
response = httpclient.execute(httpost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
if (is != null) {
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result = sb.toString();
}
jsonObject = new JSONObject(result);
Log.i("Response", "" + jsonObject.toString());
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
return jsonObject;
}
