有的童鞋没弄过京东支付跑来问我，我们项目里有用到京东支付，于是自己写了个demo，代码贴在下面，希望能帮助到不会的童鞋。
1.新建一个继承Viewcontroller的JDViewcontroller
2. 在JDViewcontroller.h文件中，定义一个url属性，用来传url(废话)
@property (nonatomic, copy) NSString *urlStr;
3.在JDViewcontroller.m文件中，导入<JavaScriptCore/JavaScriptCore.h>框架，并定义一个成员变量webView
{
UIWebView *_webView;
}
4.主要代码
- (void)viewDidLoad {
[super viewDidLoad];
self.title = @"京东支付";
self.view.backgroundColor = [UIColor whiteColor];
[self initSubView];
}
- (void)initSubView {
//创建webView
_webView = [UIWebView new];
_webView.scrollView.bounces = NO;
_webView.delegate = self;
[self.view addSubview:_webView];
_webView.frame = self.view.frame;
NSURL *url = [NSURL URLWithString:[_urlStr stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]]];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
}
//delegate
- (void)webViewDidStartLoad:(UIWebView *)webView {
}
- (void)webViewDidFinishLoad:(UIWebView *)webView {
NSLog(@"加载中,,");
NSString *currentURL = webView.request.URL.absoluteString;
NSString *theTitle = [webView stringByEvaluatingJavaScriptFromString:@"document.title"];
NSLog(@"%@==", theTitle);
NSRange range = [theTitle rangeOfString:@"支付的结果"];
if (range.length > 0) {
_webView = [UIWebView new];
NSURL *url = [NSURL URLWithString:[currentURL stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]]];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
//固定格式，js与iOS交互
JSContext *context = [_webView valueForKeyPath:@"documentView.webView.mainFrame.javaScriptContext"];
context[@"jakilllog"] = ^() {
NSString *type;
NSLog(@"begin +++++++++++++");
NSArray *args = [JSContext currentArguments];
for (JSValue *jsVal in args) {
NSLog(@"%@", jsVal);
type = [NSString stringWithFormat:@"%@",jsVal];
}
JSValue *this = [JSContext currentThis];
NSLog(@"this : %@", this);
NSLog(@" end --------------");
if ([type isEqualToString:@"success"]) {
NSLog(@"success");
}
};
}
}
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
return YES;
}
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error {
}
在主Viewcontroller中导入JDViewController.h
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor whiteColor];
//新建一个button，用来做点击事件
UIButton *btn = [UIButton buttonWithType:UIButtonTypeSystem];
btn.frame = CGRectMake(80, 180, 180, 30);
[btn setTitle:@"点击进行京东支付" forState:UIControlStateNormal];
[btn addTarget:self action:@selector(ttt:) forControlEvents:UIControlEventTouchUpInside];
btn.backgroundColor = [UIColor redColor];
[self.view addSubview:btn];
}
//点击事件
- (void)ttt:(UIButton *)btn {
NSLog(@"点击进行京东支付");
[self jdPay];
}
//支付
- (void)jdPay {
NSString *userid = @"你的ID";
NSString *money = @"0.15
";
//具体根据你们后台的参数来设置
NSDictionary *dic = [[NSDictionary alloc] initWithObjectsAndKeys:userid,@"linkTel",@"付款",@"body",money,@"actualAmount",userid,@"userId",@"1",@"deviceType", nil];
//创建对象
JDViewController *jd = [JDViewController new];
//拼接url
NSString *url = [NSString stringWithFormat:@"{\"linkTel\":\"%@\",\"body\":\"支付名称\",\"actualAmount\":\"%@\",\"deviceType\":\"1\",\"userId\":\"%@\"}", dic[@"linkTel"], dic[@"actualAmount"], dic[@"userId"]];
jd.urlStr = [NSString stringWithFormat:@"%@%@", @"你们后台接口地址message=",url];
//跳转
[self.navigationController pushViewController:jd animated:YES];
}
结果图如下
