这是php服务器端接收图片代码

Answer 1

我是这样写的 @Part("image\"; filename=\"image.png\" ") RequestBody image

Answer 2

&nbsp; Map<String, RequestBody> photoRequestBodyMap = new HashMap<>();&nbsp; &nbsp; &nbsp; &nbsp; photoRequestBodyMap.put("Content", RequestBody.create(MediaType.parse("text/plain"), et_body.getText().toString()));&nbsp; &nbsp; &nbsp; &nbsp; for (int i = 0; i < picList.size(); i++) {&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; File file = new File(picList.get(i));&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; RequestBody requestBody = RequestBody.create(MediaType.parse("image/*"), file);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; String key = "image\";filename=\"" + file.getName();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; photoRequestBodyMap.put(key, requestBody);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } catch (Exception e) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; netApiInterface&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .postMoment(photoRequestBodyMap)我是这样的。关于图片上传时要用的key，网上有多种说法。我这边，实测 String key = "image";filename="" + file.getName();可行

Answer 3

方法注解只使用POST，参数注解也只使用BODY，以及单独构造MultipartBody进行上传。retrofit2.0对上传文件支持并不那么简洁，应该去熟悉okhttp

Answer 4

如果你用的是Retrofit2.0 那 Part注解后面 后面应该是MultipartBody.Part 而不是RequestBody
