用Java中的数据发送HTTP POST请求

问题描述：

我正在尝试执行一个简单的http post请求，其中包含数据，但是我发送数据的网址正在向我返回错误信息，表明查询必须包含'code'参数。用Java中的数据发送HTTP POST请求

我们在Python中有一个脚本可以工作。它只是做到这一点：

import requests 

build_data = {'code': '827h46fh38fjg623hd6che6fhw63hf6239k589'} 
build_data['workflow.reponame'] = 'test' 
result = requests.post('https://SomeUrl', data=build_data, verify=False)

我的Java代码：

public void postReceive() 
{ 
    String payload = "{'code': '827h46fh38fjg623hd6che6fhw63hf6239k589','workflow.reponame': 'test'}" 
    makeRequest(payload) 
} 

private void makeRequest(String payload) 
{ 
    try 
    { 

     TrustManager[] trustAllCerts = new TrustManager[] {new X509TrustManager() { 
      public java.security.cert.X509Certificate[] getAcceptedIssuers() { 
      return null; 
      } 
      public void checkClientTrusted(X509Certificate[] certs, String authType) { 
      } 
      public void checkServerTrusted(X509Certificate[] certs, String authType) { 
      } 
     } 
     }; 


     // Install the all-trusting trust manager 
     SSLContext sc = SSLContext.getInstance("SSL"); 

     sc.init(null, trustAllCerts, new java.security.SecureRandom()); 
     HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory()); 

     // Create all-trusting host name verifier 
     HostnameVerifier allHostsValid = new HostnameVerifier() { 
      public boolean verify(String hostname, SSLSession session) { 
       return true; 

      } 
     }; 

     // Install the all-trusting host verifier 
     HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid); 

     String url = "https://SomeUrl"; 

     URL obj = new URL(url); 
     HttpsURLConnection con = (HttpsURLConnection) obj.openConnection(); 

     con.setRequestMethod("POST"); 
     con.setRequestProperty("User-Agent", "Mozilla/5.0"); 
     con.setRequestProperty("Accept-Language", "en-US,en;q=0.5"); 
     con.setRequestProperty("Content-Type", "application/json; charset=utf8"); 
     con.setDoOutput(true); 

     DataOutputStream wr = new DataOutputStream(con.getOutputStream()); 
     wr.write(payload.getBytes("UTF-8")); 
     wr.flush(); 
     wr.close(); 

     int responseCode = con.getResponseCode(); 

     /*HttpClient client = MySSLSocketFactory.getNewHttpClient(); 
     HttpPost post = new HttpPost("https://SomeUrl"); 

     List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1); 
     nameValuePairs.add(new BasicNameValuePair("data", payload)); 
     //nameValuePairs.add(new BasicNameValuePair("verify", false)); 
     post.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

     HttpResponse response = client.execute(post);*/ 
    } 
    catch(Exception e) 
    { 

    } 
}

我评论使用HttpClient的代码，但它做同样的事情。难道我做错了什么？

我不知道你如何检查服务器端的参数，但在你的有效载荷那些额外的“字符真的有必要？ “{code：827h46fh38fjg623hd6che6fhw63hf6239k589，workflow.reponame：test}” – user 2014-10-01 13:54:25

答

{'code': '827h46fh38fjg623hd6che6fhw63hf6239k589'}是一个python构造，它不是“按原样”发送，而是由post方法（解包和表单编码）使用。而不是

：

nameValuePairs.add(new BasicNameValuePair("data", "{'code': '827h46fh38fjg623hd6che6fhw63hf6239k589'}"));

，你应该这样做：

nameValuePairs.add(new BasicNameValuePair("code", "827h46fh38fjg623hd6che6fhw63hf6239k589"));
