【安卓相关】OkHttp之GET请求、POST请求、文件上传

发送GET请求

        OkHttpClient OkHttpGet = new OkHttpClient();
        Request requestGet=new Request.Builder().url("https://www.norkm.com/").build();
        OkHttpGet.newCall(requestGet).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {

            }

            @Override
            public void onResponse(Call call, Response response) {
                    /*
                    * 返回结果
                    * response.body().string()
                    * */
            }
        });

发送POST请求

相比GET请求也只是多了一个post方法，请求参数放置在FormBody.Builder 中。

        FormBody.Builder formBody = new FormBody.Builder();
        formBody.add("","");

        OkHttpClient okHttpPost =new OkHttpClient();
        Request requestPost = new Request.Builder().url("https://www.norkm.com/").post(formBody.build()).build();
        okHttpPost.newCall(requestPost).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {

            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                /*
                 * 返回结果
                 * response.body().string()
                 * */
            }
        });

发送POST请求，并携带文件上传

        OkHttpClient okHttpClientFile = new OkHttpClient();
        RequestBody fileBody = RequestBody.create(MediaType.parse("multipart/form-data"), new File("filePath"));
        RequestBody requestBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addFormDataPart("otherName","otherValue")
                .addFormDataPart("file", "fileName", fileBody)
                .build();

        Request uploadRequest = new Request.Builder().url("https://www.norkm.com/").post(requestBody).build();

        okHttpClientFile.newCall(uploadRequest).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {

            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                /*
                 * 返回结果
                 * response.body().string()
                 * */
            }
        });
