Android中的HTTP POST请求导致服务器崩溃

Question

我正在拔头发试图让它发挥作用。我正在使用 OkHTTP 向我的服务器发出 POST 请求。但是，我尝试使用参数成功发出 POST 请求的每种方法都会导致服务器关闭，并给出“503 服务不可用”的响应。我使用外部客户端来测试服务器，比如 Advanced Rest Client 扩展，它工作得非常好。

API 的 URL 格式为“https://mystuff-herokuapp.com/postuser”，我的正文参数是“user_id”、“userName”、“email”。我尝试在请求中添加标头，从 FormBodyEncoding() 更改为 MultiPartBuilder() 等。

onCreate

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_dashboard);
    //set toolbar as the acting action bar
    Toolbar actionToolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(actionToolbar);
    getSupportActionBar().setDisplayShowTitleEnabled(false);
    Intent intent = getIntent();
    String photoUrl = intent.getStringExtra("photo");
    String userTwitterID = intent.getStringExtra("userID");
    String userName = intent.getStringExtra("name");
    String userEmail = intent.getStringExtra("email");

    JSONObject jObject = new JSONObject();

    try {
        jObject.put("user_id", userTwitterID);
        jObject.put("userName", userName);
        jObject.put("userEmail", userEmail);
    } catch (JSONException e) {
        e.printStackTrace();
    }

    new UserApiProcess().execute(jObject);
}

异步任务

private class UserApiProcess extends AsyncTask<Object, Void, Void>{
    @Override
    protected Void doInBackground(Object... strings) {

        OkHttpClient client = new OkHttpClient();
        RequestBody formBody = new MultipartBuilder()
                .addFormDataPart("user_id", "800")
                .addFormDataPart("userName", "Nick")
                .addFormDataPart("email", "something@something.com")
                .build();
        Request request = new Request.Builder()
                .url("https://mystuff.herokuapp.com/postuser")
                .addHeader("Content-Type", "x-www-form-urlencoded")
                .post(formBody)
                .build();
        Response response = null;
        try {
            response = client.newCall(request).execute();
            if(!response.isSuccessful()) throw new IOException("Unexpected code " + response);
            System.out.println(response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }

}

来自 Advanced Rest 客户端的成功响应

我的 Android 出现服务器错误

试试这个。它应该可以工作。

private class UserApiProcess extends AsyncTask<Object, Void, Void>{

@Override
protected Void doInBackground(Object... strings) {
    OkHttpClient client = new OkHttpClient();
    RequestBody formBody = new FormEncodinBuilder()
            .add("user_id", "800")
            .add("userName", "Nick")
            .add("email", "something@something.com")
            .build();
    Request request = new Request.Builder()
            .url("https://mystuff.herokuapp.com/postuser")
            .addHeader("Content-Type", "x-www-form-urlencoded")
            .post(formBody)
            .build();
    Response response = null;
    try {
        response = client.newCall(request).execute();
        if(!response.isSuccessful()) throw new IOException("Unexpected code " + response);
        System.out.println(response.body().string());
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
    }

}
