背景

公司的文件上传接口使用PUT协议，之前一直用的都是老项目中的上传类，现在项目中使用了okhttp网络库，就查了下资料，在这里分享一下。

代码实现

okhttp 2.7.X

    /**
     * @param mediaType MediaType
     * @param uploadUrl put请求地址
     * @param localPath 本地文件路径
     * @return 响应的结果 和 HTTP status code
     * @throws IOException
    public String put(MediaType mediaType, String uploadUrl, String localPath) throws IOException {
        File file = new File(localPath);
        RequestBody body = RequestBody.create(mediaType, file);
        Request request = new Request.Builder()
                .url(uploadUrl)
                .put(body)
                .build();
        Response response = client.newCall(request).execute();
        return response.code()+ ":" + response.body().string() ;
    //上传JPG图片
    public String putImg(String uploadUrl, String localPath) throws IOException {
        MediaType Image = MediaType.parse("image/jpeg; charset=utf-8");
        return put(Image, uploadUrl, localPath);
    }

可能还需要进行的设置：修改各种 Timeout

OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(30, TimeUnit.SECONDS);
client.setReadTimeout(15, TimeUnit.SECONDS);
client.setWriteTimeout(30, TimeUnit.SECONDS);

okhttp 3.X

    /**
     * @param mediaType MediaType
     * @param uploadUrl put请求地址
     * @param localPath 本地文件路径
     * @return 响应的结果 和 HTTP status code
     * @throws IOException
    public String put(MediaType mediaType, String uploadUrl, String localPath) throws IOException {
        File file = new File(localPath);
        RequestBody body = RequestBody.create(mediaType, file);
        Request request = new Request.Builder()
                .url(uploadUrl)
                .put(body)
                .build();
        //修改各种 Timeout
        OkHttpClient client = new OkHttpClient.Builder()
                .connectTimeout(600, TimeUnit.SECONDS)
                .readTimeout(200, TimeUnit.SECONDS)
                .writeTimeout(600, TimeUnit.SECONDS)
                .build();
        //如果不需要可以直接写成 OkHttpClient client = new OkHttpClient.Builder().build();
        Response response = client
                .newCall(request)
                .execute();
        return response.body().string() + ":" + response.code();
//上传JPG图片
    public String putImg(String uploadUrl, String localPath) throws IOException {
        MediaType imageType = MediaType.parse("image/jpeg; charset=utf-8");
