Http Post With Body

Question

我已经发送了发送http帖子的objective-c中的方法，并在正文中我输了一个字符串：

NSString *requestBody = [NSString stringWithFormat:@"mystring"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:[requestBody dataUsingEncoding:NSUTF8StringEncoding]];

现在在Android中我想做同样的事情，我正在寻找一种方法来设置http帖子的主体。

Answer 1

您可以使用HttpClient和HttpPost构建并发送请求。

HttpClient client= new DefaultHttpClient();
HttpPost request = new HttpPost("www.example.com");

List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("paramName", "paramValue"));

request.setEntity(new UrlEncodedFormEntity(pairs ));
HttpResponse resp = client.execute(request);

Answer 2

您可以使用此代码段 -

HttpURLConnection urlConn;
URL mUrl = new URL(url);
urlConn = (HttpURLConnection) mUrl.openConnection();
...
//query is your body
urlConn.addRequestProperty("Content-Type", "application/" + "POST");
if (query != null) {
urlConn.setRequestProperty("Content-Length", Integer.toString(query.length()));
urlConn.getOutputStream().write(query.getBytes("UTF8"));
}

Answer 3

您可以使用HttpClient和HttpPost尝试这样的事情：

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("mystring", "value_of_my_string"));
// etc...

// Post data to the server
HttpPost httppost = new HttpPost("http://...");
httppost.setEntity(new UrlEncodedFormEntity(params));

HttpClient httpclient = new DefaultHttpClient();
HttpResponse httpResponse = httpclient.execute(httppost);

您可以使用HttpClient和HttpPost将json字符串作为正文发送：

public void post(String completeUrl, String body) {
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(completeUrl);
    httpPost.setHeader("Content-type", "application/json");
    try {
        StringEntity stringEntity = new StringEntity(body);
        httpPost.getRequestLine();
        httpPost.setEntity(stringEntity);

        httpClient.execute(httpPost);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

Json身体示例：

{
  "param1": "value 1",
  "param2": 123,
  "testStudentArray": [
    {
      "name": "Test Name 1",
      "gpa": 3.5
    },
    {
      "name": "Test Name 2",
      "gpa": 3.8
    }
  ]
}

Answer 5

 ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

然后为每对添加元素

 nameValuePairs.add(new BasicNameValuePair("yourReqVar", Value);
 nameValuePairs.add( ..... );

然后使用HttpPost：

HttpPost httppost = new HttpPost(URL);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

并使用HttpClient和Response从服务器获取响应
