Java：将原始数据添加到有效负载 Httpost 请求

Java: Adding raw data to payload Httpost request

提问by James Mclaren

I intend to send a simple http post request with a large string in the Payload.

我打算在 Payload 中发送一个带有大字符串的简单 http post 请求。

So far I have the following.

到目前为止，我有以下内容。

    DefaultHttpClient httpclient = new DefaultHttpClient();


    HttpPost httppost = new HttpPost("address location");

    String cred = "un:pw";

    byte[] authEncBytes = Base64.encodeBase64(cred.getBytes());
    String authStringEnc = new String(authEncBytes);



    httppost.setHeader("Authorization","Basic " + authStringEnc);

However, I do not know how to attach a simple RAW string into the payload. The only examples I can find are name value pairs into the Entity but this is not what I want.

但是，我不知道如何将简单的 RAW 字符串附加到有效负载中。我能找到的唯一示例是实体中的名称值对，但这不是我想要的。

Any assistance?

任何帮助？

It depends on the concrete HTTP-API you're using:

这取决于您使用的具体 HTTP-API：

Commons HttpClient (old - end of life)

Commons HttpClient（旧 - 生命周期结束）

Since HttpClient 3.0 you can specify a RequestEntityfor your PostMethod:

从 HttpClient 3.0 开始，您可以RequestEntity为您的指定一个PostMethod：

httpPost.setRequestEntity(new StringRequestEntity(stringData));

Implementations of RequestEntityfor binary data are ByteArrayRequestEntityfor byte[], FileRequestEntitywhich reads the data from a file (since 3.1) and InputStreamRequestEntity, which can read from any input stream.

RequestEntityfor 二进制数据的实现是ByteArrayRequestEntityfor byte[]，FileRequestEntity它从文件中读取数据（自 3.1 起）和InputStreamRequestEntity，它可以从任何输入流中读取。

Before 3.0 you can directly set a Stringor an InputStream, e.g. a ByteArrayInputStream, as request body:

在 3.0 之前，您可以直接设置 aString或 an InputStream，例如 a ByteArrayInputStream，作为请求正文：

httpPost.setRequestBody(stringData);

or

或者

httpPost.setRequestBody(new ByteArrayInputStream(byteArray));

This methods are deprecated now.

现在不推荐使用此方法。

HTTP components (new)

HTTP 组件（新）

If you use the newer HTTP componentsAPI, the method, class and interface names changed a little bit, but the concept is the same:

如果使用较新的HTTP 组件API，方法、类和接口名称会发生​​一些变化，但概念是相同的：

httpPost.setEntity(new StringEntity(stringData));

Other Entityimplementations: ByteArrayEntity, InputStreamEntity, FileEntity, ...

其他Entity实现：ByteArrayEntity, InputStreamEntity, FileEntity, ...

i was making a common mistake sequence of json object was wrong. for example i was sending it like first_name,email..etc..where as correct sequence was email,first_name

我犯了一个常见的错误 json 对象序列是错误的。例如我发送它像 first_name,email..etc.. 正确的顺序是 email,first_name

my code

我的代码

boolean result = false;
    HttpClient hc = new DefaultHttpClient();
    String message;

HttpPost p = new HttpPost(url);
JSONObject object = new JSONObject();
try {

    object.put("updates", updates);
    object.put("mobile", mobile);
    object.put("last_name", lastname);
    object.put("first_name", firstname);
    object.put("email", email);

} catch (Exception ex) {

}

try {
message = object.toString();


p.setEntity(new StringEntity(message, "UTF8"));
p.setHeader("Content-type", "application/json");
    HttpResponse resp = hc.execute(p);
    if (resp != null) {
        if (resp.getStatusLine().getStatusCode() == 204)
            result = true;
    }

    Log.d("Status line", "" + resp.getStatusLine().getStatusCode());
} catch (Exception e) {
    e.printStackTrace();

}

return result;
