Question

我知道之前已经多次询问过，但在阅读完所有解决方案之后，我仍然无法找到解决这个问题的方法。从最近4个小时开始我就陷入困境，所以任何帮助都会受到赞赏。这是我的ajax电话：

       $.ajax({
            url: "http://localhost:1316/MoviesWebService.asmx/saveReview",
            data: '{ username:"kartik1990",critic:"sanjayR",quote:"great",imdbId:"tt189",isCriticAMember:"true",reviewOrLikes:"review" }',
            type: 'post',
            contentType: 'application/json',
            dataType:'json',
            success: function (response) {
                console.log(response);
            }
        });

ASMX代码：

[WebMethod]
public bool saveReview(ProjLikesTO newReviewOrLike) {
    using (kkapilaCSDataContext db = new kkapilaCSDataContext()) {
        proj_like action = new proj_like();
        action.username = newReviewOrLike.username;
        action.critic = newReviewOrLike.critic;
        action.quote = newReviewOrLike.quote;
        action.imdbId = newReviewOrLike.imdbId;
        action.isCriticAMember = newReviewOrLike.isCriticAMember;
        action.reviewOrlikes = newReviewOrLike.reviewOrLikes;
        db.proj_likes.InsertOnSubmit(action);
        db.SubmitChanges();
        return true;
    }

ProjLikesTO：

public class ProjLikesTO {
    public string username {
        set;
        get;
    }
    public string critic {
        set;
        get;
    }
    public string quote {
        set;
        get;
    }
    public string imdbId {
        set;
        get;
    }
    public string isCriticAMember {
        set;
        get;
    }
    public string reviewOrLikes {
        set;
        get;
    }

    public ProjLikesTO() {
    }

    public ProjLikesTO(string username, string critic, string quote, string imdbId, string isCriticAMember, string reviewOrLikes) {
        this.username = username;
        this.critic = critic;
        this.quote = quote;
        this.imdbId = imdbId;
        this.isCriticAMember = isCriticAMember;
        this.reviewOrLikes = reviewOrLikes;
    }

}

Answer 1

在你的情况下，首先你必须在使用ajax传递之前填充对象，如下所示

var newReviewOrLike = { username:"kartik1990",critic:"sanjayR",quote:"great",imdbId:"tt189",isCriticAMember:"true",reviewOrLikes:"review" }
  $.ajax({
            url: "http://localhost:1316/MoviesWebService.asmx/saveReview",
            data:  JSON.stringify({ newReviewOrLike : newReviewOrLike }),
            type: 'post',
            contentType: 'application/json',
            dataType:'json',
            success: function (response) {
                console.log(response);
            }
        });

Answer 2

您需要对ajax方法进行一些更改..

 var newReviewOrLike= { username:"kartik1990",critic:"sanjayR",quote:"great",imdbId:"tt189",isCriticAMember:"true",reviewOrLikes:"review" };

  $.ajax({
            url: "http://localhost:1316/MoviesWebService.asmx/saveReview",
            data: JSON.stringify({'newReviewOrLike':newReviewOrLike}), // check this
            type: 'post',
            contentType: 'application/json',
            dataType:'json',
            success: function (response) {
                console.log(response);
            }
        });
