Question

目前，我正在使用Android与Retrofit 2.0.0-beta4和OkHttp3。我正在做一个如此定义的@PUT请求：

@Headers({
        Constants.CONTENT_TYPE_HEADER + ": " + Constants.JSON_HEADER_VAL,
        Constants.ACCEPT_HEADER + ": " + Constants.JSON_HEADER_VAL
})
@PUT(Constants.PUT_SKILL_LEVEL)
Call<EmployeeSkill> updateEmpSkillLevel(@Header(Constants.SESSION_COOKIE_NAME) String cookieValue, @Body EmployeeSkillRequest employeeSkillUpdate);

端点在此处：http://apps:8080/employeeSkillsService/employeeSkill。以下是PUT请求的日志输出：

我已经在Chrome上的Postman中验证过这个带有这些标头和有效负载的端点可以多次工作。然而，当我使用Retrofit时，尽管终端在Postman中工作，我仍然收到404错误。这是代码调用：

Call<EmployeeSkill> updateEmployeeSkillCall = RetrofitApiRestClient.getApiClient().updateEmpSkillLevel(cookieValue, employeeSkillUpdate);

updateEmployeeSkillCall.enqueue(new Callback<EmployeeSkill>() {

    @Override
    public void onResponse(Call<EmployeeSkill> call, Response<EmployeeSkill> response) {
        // called when response HTTP status is "200 OK"
        if (response.isSuccess()) {
            holder.spnSkillLevel.setTag(pos);
            Toast.makeText(mContext, holder.tvSkillName.getText() + mContext.getString(R.string.skill_updated_success_text)
                + holder.spnSkillLevel.getSelectedItem().toString(), Toast.LENGTH_LONG).show();

            List<EmployeeSkill> updateEmployeeSkillsRow = EmployeeSkill.find(EmployeeSkill.class, "employee = ? and skill = ?",
                response.body().getEmployee().getId().toString(), response.body().getSkill().getId().toString());

            EmployeeSkill updatedSkill = updateEmployeeSkillsRow.get(0);
            updatedSkill.setSkillLevel(response.body().getSkillLevel());
            updatedSkill.setTimeUpdated(response.body().getSkillLevel().getTimeUpdated());
            updatedSkill.save();
        }
    }

    @Override
    public void onFailure(Call<EmployeeSkill> call, Throwable throwable) {
        Toast.makeText(mContext, holder.tvSkillName.getText() + mContext.getString(R.string.skill_update_failed_text), Toast.LENGTH_LONG).show();
    }
});

我尝试将@Body参数更改为JSON字符串，但是我收到一条错误，指出JSON必须以数组或对象开头。这方面的任何帮助都会有用。如果没有这个功能，如果我找不到解决方案，我将被迫废弃Retrofit，我真的不希望这样做。

使用Fiddler2解决了我自己的问题。如果cookie名称和值不正确。邮差可能更倾向于如何发送东西与改造和其他人如何做到这一点。但是从中学到了一些东西。感谢所有协助的人。

将@PUT与Retrofit 2和OkHttp3
