android - 使用 HttpURLConnection 将调用正文添加到 POST

Question

我正在尝试使用 HTTPURLConnection 对服务器 api 进行 POST 方法调用。我的通话正文的 JSON 版本是：

{
    "grant_type"        : "password",
    "username"          : "perry.marange@zmod.co",
    "password"          : "password"
}

如何使用 httpURLConnection 添加这部分？

i think you can use the Android Rest-Client for sending data to a webservice

take classes RequestMethod.java and RestClient.java from this link https://github.com/TylerSmithNet/RESTclient-Android/tree/master/RESTclient-example/src/com/tylersmith/restclient

and use those in your project like this

String webServiceUrl = "your-service-url";
RestClient client = new RestClient(webServiceUrl);
String serverResponse = "";
String inputJsonString = "{" + 
    "    \"grant_type\"        : \"password\"," + 
    "    \"username\"          : \"perry.marange@zmod.co\"," + 
    "    \"password\"          : \"password\"" + 
    "}";
client.setJSONString(inputJsonString);
client.addHeader("Content-Type", "appication/json"); // if required
try {
    client.execute(RequestMethod.POST);
    if (client.getResponseCode() != 200) {
        // response error
    }
    else
    {
                    // the response from server
        serverResponse = client.getResponse();
    }
} catch (Exception e) {
    // handle error
}
