3.设置用户头像–js代码
function showSuccessMsg() {//fadeIn--使用淡入效果来显示$('.popup_con').fadeIn('fast', function() {setTimeout(function(){$('.popup_con').fadeOut('fast',function(){}); },1000) });
}function getCookie(name) {var r = document.cookie.match("\\b" + name + "=([^;]*)\\b");return r ? r[1] : undefined;
}$(document).ready(function () {$("#form-avatar").submit(function (e) {// 阻止表单的默认行为e.preventDefault();// 利用jquery.form.min.js提供的ajaxSubmit对表单进行异步提交$(this).ajaxSubmit({url: "/api/v1.0/users/avatar",type: "post",dataType: "json",headers: {"X-CSRFToken": getCookie("csrf_token")},success: function (resp) {if (resp.errno == "0") {// 上传成功var avatarUrl = resp.data.avatar_url;$("#user-avatar").attr("src", avatarUrl);} else if (resp.errno == "4101") {location.href = "/login.html";} else {alert(resp.errmsg);}}})});
4.修改用户名–后端代码
@api.route("/users/name", methods=["PUT"])
@login_required
def change_user_name():"""修改用户名"""# 使用了login_required装饰器后，可以从g对象中获取用户user_iduser_id = g.user_id# 获取用户想要设置的用户名req_data = request.get_json()if not req_data:return jsonify(errno=RET.PARAMERR, errmsg="参数不完整")name = req_data.get("name") # 用户想要设置的名字if not name:return jsonify(errno=RET.PARAMERR, errmsg="名字不能为空")# 保存用户昵称name，并同时判断name是否重复（利用数据库的唯一索引)try:User.query.filter_by(id=user_id).update({"name": name})db.session.commit()except Exception as e:current_app.logger.error(e)db.session.rollback()return jsonify(errno=RET.DBERR, errmsg="设置用户错误")# 修改session数据中的name字段session["name"] = namereturn jsonify(errno=RET.OK, errmsg="OK", data={"name": name})
5.修改用户名–前端代码

6.修改用户名–js代码
//修改用户名的js代码$("#form-name").submit(function(e){e.preventDefault();// 获取参数var name = $("#user-name").val();if (!name) {alert("请填写用户名！");return;}$.ajax({url:"/api/v1.0/users/name",type:"PUT",data: JSON.stringify({name: name}),contentType: "application/json",dataType: "json",headers:{"X-CSRFTOKEN":getCookie("csrf_token")},success: function (data) {if ("0" == data.errno) {$(".error-msg").hide();showSuccessMsg();} else if ("4001" == data.errno) {$(".error-msg").show();} else if ("4101" == data.errno) {location.href = "/login.html";}}});})
7.获取用户信息–后端代码
@api.route("/user", methods=["GET"])
@login_required
def get_user_profile():"""获取用户信息"""user_id = g.user_id# 查询数据库获取个人信息try:user = User.query.get(user_id)except Exception as e:current_app.logger.error(e)return jsonify(errno=RET.DBERR, errmsg="获取用户信息失败")if user is None:return jsonify(errno=RET.NODATA, errmsg="无效操作")return jsonify(errno=RET.OK, errmsg="OK", data=user.to_dict())
