This article provides an in-depth examination of the common issue where boundary parameters are missing when sending multipart/form-data requests using the Fetch API. By comparing the behavior of XMLHttpRequest and Fetch API when handling FormData objects, the article reveals that the root cause lies in the automatic Content-Type header setting mechanism. The core solution is to explicitly set Content-Type to undefined, allowing the browser to generate the complete header with boundary automatically. Detailed code examples and principle analysis help developers understand the underlying mechanisms and correctly implement file upload functionality.

This paper comprehensively examines techniques for logging complete request and response bodies in Retrofit-Android. By analyzing different logging mechanisms in Retrofit 1.x and 2.x versions, it focuses on the classic approach using setLogLevel(LogLevel.FULL) and setLog(new AndroidLog("YOUR_LOG_TAG")), supplemented by HttpLoggingInterceptor implementation based on OkHttp in Retrofit 2.x.
