How与Android的发送JSON对象在申请?
由于我是新的Android开发,我打了一个问题,JSON的形式将请求发送到Web服务。谷歌搜索,我发现以下code 发送使用参数的请求。这是我们在形式发送参数的Java类:
As I am new to Android development, I struck up with a problem sending requests to a web service in the form of JSON. Googling, I found the following code for sending requests using parameters. Here is the Java class we are sending parameters in the form of:
Main.java
Main.java
RestClient client = new RestClient(LOGIN_URL);
client.AddParam("Email", _username);
client.AddParam("Passwd", _password);
try {
client.Execute(RequestMethod.POST);
} catch (Exception e) {
e.printStackTrace();
}
String response = client.getResponse();
但在这里我要以JSON形式发送参数,例如像我想以这种形式发送参数:
But here I want to send parameters in the form of JSON, like for example I want to send parameters in this form:
{
"login":{
"Email":_username,
"Passwd":_password,
}
}
那么,谁能帮助我?我如何在JSON形式发送参数?
So, can anyone help me? How can I send parameters in the form of JSON?
推荐答案
你是发布采用图书馆被人放在一起作为围绕Apache的HttpClient的类包装的例子。这不是一个特别好的。但你并不需要使用包装可言,HttpClient的本身是死的简单运用。这里有一个code样品,你可以建立在:
The example you are posting uses a 'library' put together by someone as a wrapper around Apache's HttpClient class. It's not a particularly good one. But you don't need to use that wrapper at all, the HttpClient itself is dead simple to utilize. Here's a code sample you can build on:
final String uri = "http://www.example.com";
final String body = String.format("{\"login\": {\"Email\": \"%s\", \"Passwd\": \"%s\"}", "[email protected]", "password");
final HttpClient client = new DefaultHttpClient();
final HttpPost postMethod = new HttpPost(uri);
postMethod.setEntity(new StringEntity(body, "utf-8"));
try {
final HttpResponse response = client.execute(postMethod);
final String responseData = EntityUtils.toString(response.getEntity(), "utf-8");
} catch(final Exception e) {
// handle exception here
}
请注意,你最有可能被使用JSON库序列化POJO和创建请求JSON。
Note that you would most likely be using a JSON library to serialize a POJO and create the request JSON.
