h5 无法调起微信支付错误:商家参数格式有误

1.商家参数格式有误,请联系商家解决 参考微信官方文档罗列的常见错误

  1. APP里调起H5支付,需要在 webview 中手动设置referer, referer的作用是验证是否为安全支付来源, 代码如下: (本文以UIWebView为例)
- (BOOL) webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType) navigationType 
    NSDictionary *headers = [request allHTTPHeaderFields];
    BOOL hasReferer = [headers objectForKey:@"Referer"]!=nil;
    if (hasReferer) {
        // .. is this my referer?
        return YES;
    } else {
        // relaunch with a modified request
        dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
            dispatch_async(dispatch_get_main_queue(), ^{
                NSURL *url = [request URL];
                NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
                [request setHTTPMethod:@"GET"];
                [request setValue:@"" forHTTPHeaderField: @"Referer"];
                [self.webView loadRequest:request];
        return NO;


iOS h5 支付从微信返回直接跳转到 Safari 浏览器无法跳转到 app

修改 Referer 和配置 scheme 进行跳转

  1. 设置 Referer 值为:

    [request setValue:@"" forHTTPHeaderField: @"Referer"];  
  2. 在Xcode项目Target->Info->URL Types 添加一个scheme

  3. Referer 去除 http:// 或 https:// 依然可以进行支付

在 Safari 浏览器中进行 scheme 跳转回app

  1. h5支付完成会配置一个回调地址,在此网页中再次进行scheme跳转

    window.location.href = "scheme://"
  2. 在 Safari 中可以通过scheme打开指定 app, 经过浏览器迂回跳转到 app,也可以配置scheme进行指定页面跳转


  1. ios微信H5支付提示参数格式错误
  2. iOS 解决微信h5支付无法直接返回APP的问题
  3. iOS实现微信外部H5支付完成后返回原APP(多APP也可实现)
  4. iOS支付宝H5支付无法返回APP解决方案
  5. iOS scheme跳转机制
