Android OKHttp添加参数

Question

//request
Request.Builder requestBuilder = new Request.Builder()
            .url(url);

我已经管理了add头，但没有管理Params。

下面是一个关于如何使用okhttp来进行post请求(okhttp3)的完整示例。

将数据作为表单正文发送

RequestBody formBody = new FormBody.Builder()
        .add("param_a", "value_a")
        .addEncoded("param_b", "value_b")
        .build();

以多部分正文形式发送数据

RequestBody multipartBody = new MultipartBody.Builder()
            .setType(MultipartBody.FORM)
            .addFormDataPart("fieldName", fileToUpload.getName(),RequestBody.create(MediaType.parse("application/octet-stream"), fileToUpload))
            .build();

    RequestBody jsonBody = RequestBody.create(MediaType.parse("application/json; charset=utf-8"),
            jsonObject.toString());

    Request request = new Request.Builder()
            .addHeader("header_a", "value_a")  // to add header data
            .post(formBody)         // for form data
            .post(jsonBody)         // for json data
            .post(multipartBody)    // for multipart data
            .build();

    Response response = client.newCall(request).execute();
