多部分中的okhttp登录拦截器
Posted
技术标签:
【中文标题】多部分中的okhttp登录拦截器【英文标题】：okhttp loggin interceptor in multipart 【发布时间】：2016-11-28 12:55:17 【问题描述】：我正在尝试使用 okHTTP 多部分将图像上传到服务器。服务器不接受我的请求。我的问题是我在日志拦截器中看不到我的多部分的部分，所以我无法调试。这是我使用的代码以及生成的日志 cat 和所需的有效负载。任何帮助表示赞赏。
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("uploaded_file", filename, RequestBody.create(MEDIA_TYPE_PNG, sourceFile))
.addFormDataPart("flowChunkNumber", "1")
.addFormDataPart("flowCurrentChunkSize", String.valueOf(sourceFile.getTotalSpace()))
.addFormDataPart("flowChunkSize", "1048576")
.addFormDataPart("flowIdentifier", "4731-images1jpeg")
.addFormDataPart("flowFilename", "images (1).jpeg")
.addFormDataPart("flowFilename", "images (1).jpeg")
.addFormDataPart("flowRelativePath", "images (1).jpeg")
.addFormDataPart("flowTotalChunks", "1")
.build();
Request request = new Request.Builder()
.addHeader("cookie", ******* )
.url(URL_UPLOAD_IMAGE)
.post(requestBody)
.build();
HttpLoggingInterceptor logInterceptor = new HttpLoggingInterceptor();
logInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient
.Builder()
.addNetworkInterceptor(logInterceptor)
.build();
Response response = client.newCall(request).execute();
这就是我在使用拦截器时在日志猫中看到的内容
D/OkHttp: --> POST https://www.appido.ir/api/profile/avatar http/1.1
D/OkHttp: Content-Type: multipart/form-data; 边界=a8028055-3a30-4942-916b-af56935e8b32

这种胡言乱语持续了很多行
D/OkHttp: --> END POST (14097-byte body)
如何才能看到有意义的原木猫？我想实现这一点：

【问题讨论】：
它正在打印PNG文件的内容？ @JesseWilson 谢谢你的回答，我解决了这个问题。 在这里解决github.com/square/okhttp/pull/3833 【参考方案1】：这似乎是日志拦截器中的一个错误。
我能够解决这个问题购买调试日志拦截器。 问题是多部分的身体太大，迭代器无法一次显示这么大的身体。它需要逐行打印。 这是日志拦截器的修改版本，可与 okhttp 3.4.1 中的多部分一起使用：

【讨论】：
我可能会提交错误并请求 PR，但我之前从未做过 PR :D【参考方案2】：从 Okttp 和 Retrofit 查看 Multipart 上传内容的方法是使用 Facebook 的 Stetho，并将 StethoInterceptor 添加到 Okhttp 记录器
https://github.com/facebook/stetho
它将 Android 应用的网络请求放入开发机器的 chrome 检查器中。

感谢您的回答，但我最终编写了自己的拦截器以上是关于多部分中的okhttp登录拦截器的主要内容，如果未能解决你的问题，请参考以下文章
