okhttp 上传图片java.net.SocketTimeoutException: timeout

使用OKHttp上传图片时，发生的超时异常。推测主要是网络的原因，重新设置连接、读超时、及池化连接，将最大空闲数和等待时间设大。多，且线程池中核心线程数量设置为10，最大线程数量设置为24。调用OkHttpUtils.getInstance()获取okhttpClient对象，在并发运行时需保证足够数量的okhttp连接。原来的代码底层用的默认值：连接池最大连接空闲数5，连接超时10秒，读写超时15秒。我们重新定义okhttp连接池最大空闲数量设为32，防止无连接可用等待超时后抛异常

按上面调整后，效果好了很多。应用这个单例：

 /** * * @param bytes 待上传文件 * @param ids 运单的batch_id * @param type 1 不正常 2 车辆登记 */ public static void uploadImage(byte[] bytes,String fileName,String ids,int type,long tonce,Callback callback){ if (bytes == null || bytes.length == 0 || TextUtils.isEmpty(fileName)) return; // URL String url = "http://192.168.10.114:8080?name="+ fileName +"&ids="+ids+"&type="+type; OkHttpClient client = getInstance(); if(client == null)return; MediaType mediaType = MediaType.parse("image/jpeg"); RequestBody body = RequestBody.create(mediaType,bytes); Request request = new Request.Builder() .url(url) .method("POST", body) .addHeader("user-agent", "android") .addHeader("x-userid", "87875415646")// 添加x-userid请求头 .addHeader("x-sessionkey", "151561155")// 添加x-sessionkey请求头 .addHeader("x-tonce", Long.valueOf(tonce).toString())// 添加x-tonce请求头 .addHeader("x-timestamp", Long.valueOf(tonce).toString())// 添加x-timestamp请求头 .addHeader("Content-Type", "image/jpeg") .build(); client.newCall(request).enqueue(callback); }
}
