HTTP状态415-执行POST调用时不支持的媒体类型

Question

我看到POST请求时得到415-不支持的媒体类型。我检查了很多给出的解决方案，但似乎都没有用。我将内容类型设置为application / json。但是我仍然遇到同样的问题。

我尝试了一些解决方案，例如添加jackson-all.jar，jersey-media-json-jakson jar和添加无参数构造函数。似乎没有任何效果。

    public void setPublication(String publication) {

    "id"        : 1,
    "author"    : "J.R.R Tolkein",
    "publication" : "Allen & Unwin"

Answer 1

邮递员，我遇到了同样的问题。

我的解决方案是将我的数据以json格式以[原始]格式写入[Body]。像这样：

{“ message”：“已更新的第一篇文章！”}

并且在[标题]中：

[KEY]内容类型[值] application / json
